Mechanical considerations in impaction bone grafting. (1/715)

In impaction grafting of contained bone defects after revision joint arthroplasty the graft behaves as a friable aggregate and its resistance to complex forces depends on grading, normal load and compaction. Bone mills in current use produce a distribution of particle sizes more uniform than is desirable for maximising resistance to shear stresses. We have performed experiments in vitro using morsellised allograft bone from the femoral head which have shown that its mechanical properties improve with increasing normal load and with increasing shear strains (strain hardening). The mechanical strength also increases with increasing compaction energy, and with the addition of bioglass particles to make good the deficiency in small and very small fragments. Donor femoral heads may be milled while frozen without affecting the profile of the particle size. Osteoporotic femoral heads provide a similar grading of sizes, although fewer particles are obtained from each specimen. Our findings have implications for current practice and for the future development of materials and techniques.  (+info)

The pathogenesis of Perthes' disease. (2/715)

It has been shown that in the puppy, two infarcts separated by an interval of four weeks produce a disorder of long duration which results in flattening and broadening of the femoral head and which reproduces the radiological changes seen in Perthes' disease in man. The histological appearances produced by two infarcts are characteristic. In this study the histological appearance of fifty-seven femoral head biopsy specimens in Perthes' disease in man have been studied. In 51 per cent of hips histopathological changes characteristic of double infarction were present, and there were grounds for postulating that double infarction might eventually occur in all cases. The findings support the concept that the deformation of the femoral head and the chronicity of Perthes' disease in man may be due at least as much or even more to repeated episodes of infarction and the ensuing abnormalities of growth as to mechanical factors related to weight-bearing.  (+info)

The influence of weight-bearing on the measurement of polyethylene wear in THA. (3/715)

We have studied the influence of weight-bearing on the measurement of wear of the polyethylene acetabular component in total hip arthroplasty using two techniques. The measured vertical wear was significantly greater when radiographs were taken weight-bearing rather than with the patient supine (p = 0.001, method 1; p = 0.007, method 2). Calculations of rates of linear wear of the acetabular component were significantly underestimated (p < 0.05) when radiographs were taken supine. There are two reasons for this. First, a change in pelvic orientation when bearing weight ensures that the thinnest polyethylene is brought into relief, and secondly, the head of the femoral component assumes the position of maximal displacement along its wear path. Interpretation of previous studies on both linear and volumetric polyethylene wear in total hip arthroplasty should be reassessed in the light of these findings.  (+info)

Accuracy of EBRA-FCA in the measurement of migration of femoral components of total hip replacement. Einzel-Bild-Rontgen-Analyse-femoral component analysis. (4/715)

Several methods of measuring the migration of the femoral component after total hip replacement have been described, but they use different reference lines, and have differing accuracies, some unproven. Statistical comparison of different studies is rarely possible. We report a study of the EBRA-FCA method (femoral component analysis using Einzel-Bild-Rontgen-Analyse) to determine its accuracy using three independent assessments, including a direct comparison with the results of roentgen stereophotogrammetric analysis (RSA). The accuracy of EBRA-FCA was better than +/- 1.5 mm (95% percentile) with a Cronbach's coefficient alpha for interobserver reliability of 0.84; a very good result. The method had a specificity of 100% and a sensitivity of 78% compared with RSA for the detection of migration of over 1 mm. This is accurate enough to assess the stability of a prosthesis within a relatively limited period. The best reference line for downward migration is between the greater trochanter and the shoulder of the stem, as confirmed by two experimental analyses and a computer-assisted design.  (+info)

The prediction of failure of the stem in THR by measurement of early migration using EBRA-FCA. Einzel-Bild-Roentgen-Analyse-femoral component analysis. (5/715)

We report the ten-year results for three designs of stem in 240 total hip replacements, for which subsidence had been measured on plain radiographs at regular intervals. Accurate migration patterns could be determined by the method of Einzel-Bild-Roentgen-Analyse-femoral component analysis (EBRA-FCA) for 158 hips (66%). Of these, 108 stems (68%) remained stable throughout, and five (3%) started to migrate after a median of 54 months. Initial migration of at least 1 mm was seen in 45 stems (29%) during the first two years, but these then became stable. We revised 17 stems for aseptic loosening, and 12 for other reasons. Revision for aseptic loosening could be predicted by EBRA-FCA with a sensitivity of 69%, a specificity of 80%, and an accuracy of 79% by the use of a threshold of subsidence of 1.5 mm during the first two years. Similar observations over a five-year period allowed the long-term outcome to be predicted with an accuracy of 91%. We discuss the importance of four different patterns of subsidence and confirm that the early measurement of migration by a reasonably accurate method can help to predict long-term outcome. Such methods should be used to evaluate new and modified designs of prosthesis.  (+info)

The pathology of bone allograft. (6/715)

We analysed the histological findings in 1146 osteoarthritic femoral heads which would have been considered suitable for bone-bank donation to determine whether pathological lesions, other than osteoarthritis, were present. We found that 91 femoral heads (8%) showed evidence of disease. The most common conditions noted were chondrocalcinosis (63 cases), avascular necrosis (13), osteomas (6) and malignant tumours (one case of low-grade chondrosarcoma and two of well-differentiated lymphocytic lymphoma). There were two with metabolic bone disease (Paget's disease and hyperparathyroid bone disease) and four with inflammatory (rheumatoid-like) arthritis. Our findings indicate that occult pathological conditions are common and it is recommended that histological examination of this regularly used source of bone allograft should be included as part of the screening protocol for bone-bank collection.  (+info)

Histopathology of retrieved allografts of the femoral head. (7/715)

From November 1994 to March 1997, we harvested 137 grafts of the femoral head from 125 patients for donation during total hip arthroplasty according to the guidelines of the American Associations of Tissue Banks (AATB) and the European Association of Musculo-Skeletal transplantation (EAMST). In addition to the standards recommended by these authorities, we performed histopathological examination of a core biopsy of the retrieved bone allograft and of the synovium. Of the 137 allografts, 48 (35.0%) fulfilled all criteria and were free for donation; 31 (22.6%) were not regarded as suitable for transplantation because the serological retests at six months were not yet complete and 58 (42.3%) were discarded because of incomplete data. Of those discarded, five showed abnormal histopathological findings; three were highly suspicious of low-grade B-cell lymphoma, one of monoclonal plasmacytosis and the other of non-specific inflammation of bone marrow. However, according to the standards of the AATB or EAMST they all met the criteria and were eligible for transplantation. Our findings indicate that the incidence of abnormal histopathology in these retrieved allografts was 3.6%. Since it is essential to confirm the quality of donor bones in bone banking, we advise that histopathological screening of donor bone should be performed to exclude abnormal allografts.  (+info)

Decrease in the mesenchymal stem-cell pool in the proximal femur in corticosteroid-induced osteonecrosis. (8/715)

We have evaluated bone-marrow activity in the proximal femur of patients with corticosteroid-induced osteonecrosis and compared it with that of patients with osteonecrosis related to sickle-cell disease and with a control group without osteonecrosis. Bone marrow was obtained by puncture of the femoral head outside the area of necrosis and in the intertrochanteric region. The activity of stromal cells was assessed by culturing fibroblast colony-forming units (FCFUs). We found a decrease in the number of FCFUs outside the area of osteonecrosis in the upper end of the femur of patients with corticosteroid-induced osteonecrosis compared with the other groups. We suggest that glucocorticosteroids may also have an adverse effect on bone by decreasing the number of progenitors. The possible relevance of this finding to osteonecrosis is discussed.  (+info)

Although obesity is a risk factor for hip osteoarthritis (OA), the role of body composition, if any, is unclear. This study examines whether the body mass index (BMI) and body composition are associated with hip cartilage changes using magnetic resonance imaging (MRI) in community-based adults. 141 community-based participants with no clinical hip disease, including OA, had BMI and body composition (fat mass and fat free mass) measured at baseline (1990 to 1994), and BMI measured and 3.0 T MRI performed at follow-up (2009-2010). Femoral head cartilage volume was measured and femoral head cartilage defects were scored in the different hip regions. For females, baseline BMI (β = −26 mm3, 95% Confidence interval (CI) -47 to −6 mm3, p = 0.01) and fat mass (β = −11 mm3, 95% CI −21 to −1 mm3, p = 0.03) were negatively associated with femoral head cartilage volume. Also, while increased baseline fat mass was associated with an increased risk of cartilage defects in the central superolateral region
Femoral neck fracture is one of the most common complications of hip resurfacing and considered by some to be related to reduced blood flow as a consequence of the surgical approach. We measured oxygen concentration during hip resurfacing through the trochanteric flip approach (n = 15 patients) and compared this approach with previous data for the posterior and anterolateral approaches. With the trochanteric flip the average femoral oxygenation decreased during the procedure to approximately 50% of that at the start, however it recovered to starting level by the end of the procedure. Preservation of oxygenation with the trochanteric flip was similar to that observed with the anterolateral approach, but with less variation during the procedure. Both of these approaches were superior in terms of oxygenation preservation to the posterior approach which resulted in a dramatic reduction in oxygenation.
TY - JOUR. T1 - Microcracks in articular calcified cartilage of human femoral heads. AU - Mori, S.. AU - Harruff, R.. AU - Burr, David. PY - 1993. Y1 - 1993. N2 - The purpose of this work was to determine whether microcracks occur in calcified cartilage in vivo, and to use histological techniques to separate these from artifacts caused by processing. Six femoral heads without disease were split in the frontal plane. Sections from one slab were cut to 150 μm and stained with basic fuchsin. The other slab was stained en bloc, and sections were cut to 150 μm after staining. Sections were examined microscopically, and microcrack density was calculated. Data show that microcracks occur routinely in calcified cartilage from nondiseased femoral heads of aged humans, and that they can be separated from processing artifact. Their physiological significance is unknown, but it is possible that microcracks may trigger vascular invasion of subchondral bone and may play a role in the initiation and ...
Few data are available concerning structural changes at the hip observed by magnetic resonance imaging (MRI) in people with or without hip osteoarthritis (OA). The aim of this study was to compare cartilage volume and the presence of cartilage defects and bone marrow lesions (BMLs) in participants with and without diagnosed hip OA. Femoral head cartilage volume was measured by MRI for 141 community-based persons with no diagnosed hip OA, and 19 with diagnosed hip OA. Cartilage defects and BMLs were regionally scored at the femoral head and acetabulum. Compared with those without diagnosed hip OA, people with diagnosed hip OA had less femoral head cartilage volume (1763 mm3 versus 3343 mm3; p |0.001) and more prevalent cartilage defects and BMLs (all p ≤0.05) at all sites other than the central inferomedial region of the femoral head. In those with no diagnosed hip OA, cartilage defects in the anterior and central superolateral region of the femoral head were associated with reduced femoral head
TY - JOUR. T1 - Diagnosis of Avascular Necrosis of the Femoral-Head in Patients Treated for Lymphoma. AU - Ratcliffe, M A AU - Gilbert, Fiona Jane. AU - Dawson, A A AU - Bennett, B. PY - 1995/5. Y1 - 1995/5. N2 - Avascular necrosis of bone (AVNB) is a well-known but rare complication of chemotherapy for lymphoma with a reported incidence ranging from 1 to 10 per cent. Early diagnosis is essential for optimal therapeutic management. Using MRI, the most sensitive means of detecting the earlier stages of AVNB, 100 patients treated with standard chemotherapy for lymphoma were assessed. Fifteen were found to have changes of AVNB, 10 with early changes but five with advanced segmental collapse of the femoral head. None with AVNB had more than the standard course of corticosteroids.Almost a quarter of the study group complained of joint pain during and/or after their treatment, a third of whom were found to have AVNB; a strong indicator to screen all those with pain. However, 40 per cent of those with ...
The size and shape of the acetabulum and of the femoral head influence the injury tolerance of the hip joint. The aim of this study is to quantify changes in acetabular cup geometry that occur with age, gender, height, and weight. Anonymized computed tomography (CT) scans of 1,150 individuals 16+ years of age, both with and without hip trauma, were used to describe the acetabular rim with 100 equally spaced points. Bilateral measurements were taken on uninjured patients, while only the uninjured side was valuated in those with hip trauma. Multinomial logistic regression found that after controlling for age, height, weight, and gender, each 1 degree decrease in acetabular anteversion angle (AAA) corresponded to an 8 percent increase in fracture likelihood (p≺0.001). Age, weight, and gender were found to influence anteversion angle significantly, with each 10 years in age increasing AAA by 1.07 degrees, each 10 kg of weight decreasing AAA by 0.45 degrees, and being female resulting in 1.42 ...
we report the early results and complications of resurfacing arthroplasty using the trochanteric Flip osteotomy approach to the hip. there are no published clinical results of this approach used for resurfacing arthroplasty. one hundred consecutive patients were assessed prospectively for a minimum follow-up of 2 years (range 2 - 5 years). the oxford Hip score fell from a median of 30 pre-operatively to 5 at two years. similar improvement was found in the UCLA activity score. there were no cases of component failure or fractures. However, nine patients had minor complications related to the osteotomy. resurfacing arthroplasty of the hip may be successfully performed through a trochanteric flip osteotomy. this surgical approach may avoid some of the complications associated with avascular necrosis of the femoral head.

Developmental toxicity of 4-octylphenol (OP), an estrogenic endocrine disruptor was verified using frog embryo teratogenesis assay Xenopus. LC50, EC50Malformtion and EC50Melanocyte-dysgenesis of OP were 9.9, 10.5, and 2.4 μM, respectively. In tadpoles, despite the low teratogenic index, 2 μM OP significantly inhibited head cartilage development and tail malformation. The total length of tadpole was significantly increased at 5 μM and decreased at 10 μM OP. In OP-treated tadpoles, head cartilages were frequently missed and col2a1 mRNA was decreased at 2 μM, indicating a chondrogenic defect in developing head. In the head skin of 1 μM OP-treated tadpoles, number of melanocytes and melanogenic pathway genes expression were significantly decreased. In the head-neck junction of stage 22 embryos, OP increased foxd3 and sox10 mRNA and SOX10(+) neural crest cells (NCCs) in somite mesoderm and endoderm, indicating the inhibition of chondrogenic differentiation, ectopic migration to endoderm, and ...
All-Metal-Hips; We expect not many patients are demanding them right now. Its incredible how these bandwagons gain momentum isnt it? Although less so when the enormity of the problem and its impact on a significant patient group is factored in. Perhaps its also unsurprising that after the coverage of last weeks British Hip Society Meeting, the repercussions are now exercising clinicians and the medical and non medical media around the world.. The issue, as if you need reminding, is that in recent days the UK MHRA has issued guidance suggesting that patients with implanted metal-on-metal hips above a certain femoral head diameter (36mm) and all metal-on-metal hips from DePuys ASR range should undergo a regime of lifelong testing for signs of wear or failure.. Following MHRA issuing guidance, the British Hip Society(BHS) met in Manchester last week and debated the subject again at great length, issuing this document in conjunction with the British Orthopaedic Association(BOA), explaining its ...
Fig. 1: The Zetos culture system: the loading device (left), a set of diffusion culture chambers (arrow), each with their own media supply from a reservoir (right) through Tygon tubing with the aid of a peristaltic pump (white box).. This novel system (Ref. 1) combines a set of housing chambers for the cancellous bone tissue, as well as a loading device to apply daily physiological mechanical stimulation (Figure 1). Cancellous bone tissue from ovine distal femora, bovine metacarpals or human femoral heads (Ethic Commission Graubünden (18/02) approval), were excised and cut into 9mm thick sections with the use of an Exakt 300 band saw. No animals were sacrificed specifically for this work, bovine material was collected from the local slaughterhouse and ovine material was used from animals after sacrifice for other experiments. Cores 10mm in diameter were bored out from the sections and cut parallel to 5mm with an annular saw. Bone cores were inserted inside the diffusion culture chambers and ...
TY - JOUR. T1 - A modified posterior approach preserves femoral head oxgenation during hip resurfacing. AU - Steffen, R. T.. AU - De Smet, K. A.. AU - Murray, D. W.. AU - Gill, H. S.. PY - 2011. Y1 - 2011. N2 - In 11 patients, the oxygenation was measured in the superolateral quadrant of the femoral head during resurfacing with a modified posterior approach, designed to preserve the blood supply, using a gas-sensitive electrode. These were compared with measures from 10 patients in whom the standard posterior approach was used. The modified approach patients maintained a significantly (P ,.005) higher amount of relative oxygenation after the approach, 78% (standard deviation [SD], 45%) vs 38% (SD, 26%), and acetabular component implantation, 74% (SD, 56%) vs 20% (SD, 28%). The modified posterior approach, unlike the standard extended approach, does not significantly compromise the blood supply to the head; and we recommend this approach be considered for hip resurfacing.. AB - In 11 patients, ...
Bone growth ex vivo: sheep femora, bovine metacarpals or human femoral heads were cut at the joint into 7 mm thick sections. Cancellous bone cores, 10 mm in diameter, were drilled from the sections and then cut parallel to the height of 5 mm. Throughout all cutting procedures the bone was irrigated with sterile saline to limit the amount of damage caused by heat and to stop the bone from drying out. Bone cores were washed in cell culture medium (containing tested foetal calf serum) and antibiotics for 30 minutes before being inserted into the chambers. The assembled system was allowed to settle for 36 hours at 37°C (Fig. 1). The set up for the Zetos system consists of two parts. One part is a number of cross-flow circumfusion chambers, where trabecular bone cores are situated. These cores are circumfused by a constant flow of media, which is circulated in a closed system for 1-2 days. The second part is a computer controlled loading device, which is used to maintain the bone in a loaded ...
Femoral Head Ostectomy (FHO) is the surgical procedure in which the femoral head and the neck are removed from the femur bone at the hip joint. The neck and head are not replaced and over time a layer of scar tissue develops at the point where the neck was removed. This scar tissue forms a false joint which prevents bone-to-bone rubbing, discomfort and pain. ...

Metastases to the bone as the sole manifestation of recurrence of a gastric carcinoma are extremely rare. We herein report the case of a 63-year-old man operated a year and a half before for a poorly differentiated gastric carcinoma affecting the fundus, who developed bilateral metastasis to the femoral head as the sole manifestation of recurrence. He was treated with radiotherapy to control pain with a poor response and both femoral heads had to be eventually resected. We review the literature on the rare occurrence of osseous metastasis from gastric carcinoma and comment briefly on the therapeutic options for these cases.
A hip replacement is performed by separating a femoral head from a femoral neck in a patients body, fragmenting of the femoral head and removing the fragments from the body, and molding in-situ in the body a neo femoral head joined to the femoral neck. The molding is performed by inserting a molding device, formed of bioabsorbable material, through a hole formed through the femoral head and the femoral neck. The molding device includes an expandable balloon which is expanded by the introduction of molding material, whereby the balloon forms the shape of the neo femoral head.

Aseptic necrosis of the femoral head (ANFH) has a high incidence in the community and causes substantial problems with health as well as economic and social stress. Core decompression is the most commonly used treatment for early ANFH. Although many studies have reported on the efficacy of femoral head core decompression surgery for ANFH, there are still some shortcomings in assessing the severity of femoral head necrosis, the location distribution, and changes in necrotic lesions before and after surgery. Magnetic resonance imaging (MRI) and equivalent sphere model analysis were used to further clarify the clinical efficacy of percutaneous multiple small-diameter drilling core decompression in patients with ANFH. From July 2013 to November 2016, 24 patients (32 cases of the hip joint) with ANFH who underwent percutaneous multiple small-diameter drilling core decompression were selected, and a retrospective analysis was conducted. MRI as well as VAS, OHS-C, and HHS scores were used to evaluate joint
What is the prevalence of symptomatic or asymptomatic femoral head osteonecrosis in patients previously treated with chemoradiation? A magnetic resonance study of anal cancer patients. It is generally assumed that femoral head osteonecrosis (FHO) is a serious but rare complication of pelvic radiotherapy. A review of the literature carried out by the authors indicates a prevalence of 4/763 (95% confidence interval 0.1%-1.3%). A recent publication has suggested that the prevalence of symptomatic FHO may be much greater than previously assumed as a result of sensitization of bone to radiation by concomitant treatment with chemotherapy. Magnetic resonance imaging (MRI) is currently the most sensitive modality for detecting and confirming symptomatic or asymptomatic FHO of any aetiology. The aim of this study therefore was to assess the prevalence of symptomatic and asymptomatic FHO in patients previously treated for anal cancer by chemoradiation (CRT). The hips of 34 currently disease-free ...

Veterinarian Seiche Genger, a first year resident in the poultry health management program at the College of Veterinary Medicine, carries a supplemental feeder down the center aisle of the chick-filled teaching animal unit poultry house Tuesday morning, Feb. 10, 2015. Genger is conducting a study to determine if the lesions associated with femoral head necrosis, an osteopathology commonly associated with lameness in poultry, are being artificially induced by the necropsy techniques currently being used or if they are truly a result of pathologic changes in the metaphyseal region of the femur. There is a lot of argument in the veterinary field if [these lesions] are truly indicative of femoral head necrosis or not because we find that samples submitted from the field that have been positively identified with femoral head necrosis to our laboratory here, and other diagnostic labs, histopathologically dont indicate such lesions, said Genger ...
Legg-Calve-Perthes disease (LCPD) is a rare hip disease that affects children. It is a pattern of bone tissue death and repair at the hip which can cause abnormal growth and development in children. The hip is made of the ball-shaped head of the thigh bone (femoral head) and bowl-shaped socket of the pelvis. LCPD affects the femoral head. There are 4 stages of LCPD: Severity of LCPD depends on the childs age when the disease started and how much damage was done during fragmentation.
Teichtahl et al studied the dominant hip on 3T MRI in 141 community participants recruited from the MCCS who had never been diagnosed with OA and had no symptoms of hip OA, and 19 separately recruited participants meeting American College of Rheumatology (ACR) criteria for hip OA, including K-L grade ,1. This study confirmed that the OA participants had significantly reduced femoral head cartilage volumes (FHCV) compared with their non-OA counterparts, with mean values 1763±321 vs 3343±808 mm3, p,0.001.10 In addition, cartilage defects and bone marrow lesions were more prevalent in the OA participants after adjusting for age, gender and BMI. Further work by the same investigators on presumably the same cohort of 141 non-OA participants showed that FHCV was significantly and substantially higher in men than women (mean 3891±636 vs 2867±451 mm3, respectively). In women only, increasing BMI correlated negatively with FHCV and with increased cartilage defects. Interestingly, increased fat-free ...
We have used a combination of hip distraction and the principles of diamond concept for bone regeneration to treat a femoral head suffering from advanced avascular necrosis (AVN). In such cases hip preservation is impossible and patients are treated with hip replacement. Our treatment modality preserved the hip joint offering an excellent outcome and can be used as a salvage technique for advanced femoral head osteonecrosis. This is the first reported case where such modality was applied.

TY - JOUR. T1 - Avascular necrosis of the femoral head in HIV positive patients-an assessment of risk factors and early response to surgical treatment. AU - Chokotho, L. AU - Harrison, W. AU - Lubega, Nicholas. AU - Mkandawire, Nyengo. PY - 2013. Y1 - 2013. N2 - 26 consecutive patients (37 hips) with avascular necrosis (AVN) of the femoral head treated surgically at our institution from 1999 to 2008 were reviewed. The aims of the study were to evaluate the risk factors associated with AVN in HIV positive and HIV negative individuals, and assess early response to total hip replacement (THR) surgery in HIV positive and negative patients. There were 15 male and 11 female patients in total. The mean age for all patients was 47.1± 8.0 years (range, 33 to 66 years). 12 patients were HIV positive, 11 patients were HIV negative and 3 patients had unknown HIV status. Excessive alcohol intake was the most common risk factor for developing AVN.15 patients (58%) had more than one risk factor for AVN and ...
The paper, published in The Journal of Arthroplasty, cited a recent report of a noticeable increase in hip revision surgeries due to adverse reactions to metal debris. The authors found the failure rate revealed in their study very worrisome because of the great number of hip replacements implanted and the apparently irreversible soft tissue damage that can occur due to adverse reactions to cobalt metal such as metallosis, tissue death, and pseudotumors.. To avoid complications due to corrosion at the head-neck junction (taper/trunnion), the authors suggested attaching ceramic femoral heads to titanium femoral stems, thereby avoiding use of cobalt-chromium components where possible..

All 20 patients underwent magnetic resonance imaging (MRI) within 2 months after the first symptoms. Follow-up MRI after treatment was performed in 10 patients. The subchondral fracture line in radiographs and serial T1-weighted image was used to measure the extent of the epiphyseal necrosis volumetrically. These extents in the early stage were compared with those in the late stage for determination of prognostic significance. The intensities of coronal MRIs under the subchondral fracture were not homogeneous. The uninvolved epiphysis ...

AAAS Fellow William Catterall wants to unravel the mysteries of autism. To do this, hes examining a debilitating form of the disorder that causes seizures and sometimes death in young children. His key suspects: a genetic mutation and tiny bioelectrical circuits called ion channels.. Ion channels are a series of minute electrical-signaling pathways that use electrons from ions to aid numerous biological processes-from triggering the release of neurotransmitters to helping the body absorb nutrients. They are now recognized as so fundamental to essential biological processes that theyre often called gatekeepers.. Unlocking the secrets of ion channels-how they work and how theyre structured-has instigated a tsunami of research. Surfing one crest is Catterall.. A gray-haired professor in his late sixties, Catterall chairs the pharmacology department at the University of Washington, where he runs a lab that focuses on sodium and calcium ion channels, so named because they use ions of sodium and ...
INTRODUCTION: Cam femoroacetabular impingement (FAI) is characterized by an osseous overgrowth on the femoral head-neck junction [1], leading to pain and limited range of motion (ROM) during daily life activities [2]. Corrective surgery is highly recommended and performed in order to reduce or eliminate pain and further development of osteoarthritis (OA). However, it is still unclear whether it would lead to improved functional mobility. The purpose was to compare kinematic variables of the operated limb between FAI patients when performing a squat task pre-surgery and at around 2-year follow-up. A secondary objective consisted of express the results in a biomechanical functional score to quantify the joint kinematics of FAI patients compared to healthy control (CTRL) participants. METHODS: Eleven male patients (7 arthroplasty: 34.6±8.1 years, 25.7±3.2 kg/m2; 4 open: 33.3±7.1 years, 24.9±1.9 kg/m2) and 21 CTRL (2F/19M, 33.4±6.7 years, 25.4±3.3 kg/m2) participants were recruited from the ...

Avascular necrosis (AVN) of the femoral head (FH) is believed to be caused by a multitude of etiologic factors and is associated with significant morbidity in younger populations. Eventually, the disease progresses and results in FH collapse. Thus, a focus on early disease management aimed at joint preservation by preventing or delaying progression is key. The use of stem cells (SC) for the treatment of AVN of the FH has been proposed. We undertook a systematic review of the medical literature examining the use of SC for the treatment of early stage (precollapse) AVN of the FH, in both pre-clinical and clinical studies. Data collected included: Pre-clinical studies - model of AVN, variety and dosage of SC, histologic and imaging analyses. Clinical studies - study design, classification and etiology of AVN, SC dosage and treatment protocol, incidence of disease progression, patient reported outcomes, volume of necrotic lesion and hip survivorship. In pre-clinical studies, the use of SC uniformly
Background: The hip essentially represents the major weight-bearing joint of the human organism. It is conspicuously characterized by its mobility and complex origination, specific organization and development. The anatomic structures referred to as acetabulum and femoral head arise from the same primitive mesenchymal cells and, by the end of the 11th week of gestation, the hip joint becomes fully formed and continues to develop throughout intrauterine life. During embryonic life, the femoral head grows at a faster rate than the acetabulum, and at the end of gestation the femoral head is approximately less than 50% covered, and after birth, the growth rate of the acetabular cartilage surpasses that of femoral head thus resulting in progressively increased coverage. Methods: Cartilaginous at birth, the ossification of acetabulum is set at around a three-month age period, while ossification centers of the proximal femur start to appear at 4 to 7

Ceramic-on-ceramic bearing couples are theoretically attractive in total hip arthroplasty (THA) because of low wear, but concerns regarding ceramic fracture and squeaking have arisen. Improved material properties of newer alumina matrix composite (AMC) materials, known as Delta ceramics, may reduce these risks. In addition, the use of thinner liners and larger femoral heads may be helpful clinically to lower the rate of dislocation. However, limited short-term clinical results are available and intermediate-term effects are unclear.. ...

Perthes : Perthes disease is a rare childhood disorder which affects the head of the femur. In Perthes disease, the blood supply to the growth plate of the bone at the end of the femur (called the epiphysis), becomes inadequate. As a result the bone softens and breaks down (a process called necrosis).. It is not clear why this blood vessel problem occurs in the femoral head. It is neither due to injury nor due to a general blood vessel problem. A child with Perthes disease is usually otherwise well and over several months the blood vessels regrow, and the blood supply returns to the dead bone tissue. New bone tissue is then laid down and the femoral head regrows and remodels over several years. This is similar to bone reform and remodelling after any normal fracture or breakage to the bone, but takes longer time.. ...
