The prevalence and clinicopathological appearance of extension of osteonecrosis in the femoral head. (1/547)

In about 50% of cases, osteonecrosis of the femoral head is known to occupy more than one site. There is controversy as to whether a single focus may increase in size. We have reviewed 606 consecutive femoral heads which had been surgically removed for osteonecrosis. Extension of osteonecrosis was observed in only two (0.3%) and was confirmed histopathologically by the enlargement of the necrotic segment beyond the repair zone formed for the primary necrosis into the adjacent, previously uninvolved bone. In both cases, the necrotic regions were wedge-shaped and occupied over 80% of the femoral head. It appears that an increase in size is extremely rare and that osteonecrosis is due to a single event. Our findings may be of value in assessing the use of joint-salvage procedures for osteonecrosis of the femoral head.  (+info)

Decrease in the mesenchymal stem-cell pool in the proximal femur in corticosteroid-induced osteonecrosis. (2/547)

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)

Slipped capital femoral epiphysis after septic arthritis of the hip in an adolescent: report of a case. (3/547)

Septic arthritis of the hip must be managed promptly to avoid the serious complications associated with the condition. In the case reported here, the diagnosis was delayed and was complicated by a slipped capital femoral epiphysis. The patient, an adolescent boy previously in good health, presented with a 2-week history of hip pain and systemic illness. Septic arthritis was diagnosed and was managed by incision and drainage and antibiotic therapy. Two weeks later he presented with a subcutaneous abscess and a slipped capital femoral epiphysis, which was pinned in situ. There was a 2.5-cm leg-length discrepancy. Avascular necrosis of the femoral head subsequently developed leaving the boy with a permanent disability.  (+info)

Cyclosporin A mono-therapy in nephrotic syndrome with contra-indication of steroid therapy. (4/547)

We describe three cases of nephrotic syndrome with a contra-indication for steroid therapy successfully treated with cyclosporin A (CsA). A 21-year-old man with focal segmental glomerulosclerosis (FSGS) complicated by necrosis of the femoral head, and a 34-year-old woman and a 48-year-old man with minimal change disease (MCD) complicated by psychogenic reaction and diabetes mellitus, respectively, were given CsA at initial dosages of 3.8-5.0 mg/kg/day and immediately remitted completely. However, two of these patients suffered relapses when CsA was tapered. They are currently maintained in complete or partial remission on CsA at dosages of 3.2-4.7 mg/kg/day. These findings suggest that CsA mono-therapy may be useful in nephrotic syndrome patients contra-indicated for steroid therapy.  (+info)

Increased level of apolipoprotein B/apolipoprotein A1 ratio as a potential risk for osteonecrosis. (5/547)

OBJECTIVE: This study was performed to investigate whether a high ratio of apolipoprotein B to apolipoprotein A1 (apo B/apo A1 ratio) is significantly associated with the risk of developing non-traumatic osteonecrosis of the femoral head (ON). METHODS: Fifty consecutive non-traumatic ON cases were compared with 50 age and sex matched controls, using both univariate and stepwise discriminant analyses, regarding the factors of corticosteroid, alcohol, cigarettes, cholesterol, triglyceride, and apo B/apo A1 ratio. To eliminate the possibility that ON or osteoarthritic change itself can increase the apo B/apo A1 ratio, a further 32 consecutive cases comprising nine traumatic ON and 23 osteoarthritis (OA) patients were analysed using Scheffe's test. RESULTS: There was a significant association between a high apo B/apo A1 ratio and the development of non-traumatic ON with both univariate (p=0.0001) and stepwise discriminant analyses (partial r(2)=0.1239, p=0.0004). The apo B/apo A1 ratio in the non-traumatic ON group was significantly higher than that in the traumatic ON (p<0.01), control (p<0.001), or the OA groups (p<0.001). CONCLUSION: A high apo B/apo A1 ratio is significantly associated with the risk of developing ON. This ratio may be useful for assessing the potential risk of developing osteonecrosis.  (+info)

Treatment of osteonecrosis of the femoral head by free vascularized fibular grafting: an analysis of surgical outcome and patient health status. (6/547)

OBJECTIVE: To evaluate the limb-specific outcome and general health status of patients with osteonecrosis of the femoral head treated with vascularized fibular grafting. DESIGN: A retrospective review. SETTING: A single tertiary care centre. PATIENTS: Fifty-five consecutive patients with osteonecrosis of the femoral head who underwent fibular grafting (8 bilaterally). INTERVENTION: Vascularized fibular grafting. OUTCOME MEASURES: Limb-specific scores (Harris Hip Score, St. Michael's Hospital Hip Score), general health status (Nottingham Health Profile, SF-36 health status survey) and radiographic outcome measures (Steinberg stage). RESULTS: Patients were young (mean age 34 years, range from 18 to 52 years) and 80% had advanced osteonecrosis (Steinberg stages IV and V). Fifty-nine hips were followed up for an average of 50 months (range from 24 to 117 months) after vascularized fibular grafting. Sixteen hips (27%) were converted to total hip arthroplasty (THA). To date, 73% of hips treated with vascularized fibular grafting have required no further surgery. Preoperative and postoperative Harris Hip Scores were 57.3 and 83.6 respectively (p < 0.001). As measured by patient-oriented health status questionnaires (SF-36, Nottingham Health Profile) and compared with population controls, patients had normal mental health scores and only slight decreases in physical component scores. CONCLUSIONS: Free vascularized fibular grafting for osteonecrosis of the femoral head provides satisfactory pain relief, functional improvement and general health status and halts the progression of symptomatic disease.  (+info)

Diagnostic criteria for non-traumatic osteonecrosis of the femoral head. A multicentre study. (7/547)

Six major and seven minor diagnostic criteria have been developed by the Japanese Investigation Committee for osteonecrosis of the femoral head (ONFH). We have carried out a multicentre study to clarify these. We studied prospectively 277 hips in 222 patients, from six hospitals, who had ONFH and other hip pathology and from whom histological material was available. We identified five criteria with high specificity: 1) collapse of the femoral head without narrowing of the joint space or acetabular abnormality on radiographs, including the crescent sign; 2) demarcating sclerosis in the femoral head without narrowing or acetabular abnormality; 3) a 'cold-in-hot' appearance on the bone scan; 4) a low-intensity band on T1-weighted images (band pattern); and 5) evidence of trabecular and marrow necrosis on histological examination. With any combination of two of these criteria, the sensitivity and specificity of the diagnosis were 91% and 99%, respectively.  (+info)

Femoral head necrosis treated with vascularized iliac crest graft. (8/547)

We reviewed 24 hips with avascular necrosis of the femoral head in 24 patients treated with vascularized iliac bone grafts 12 years after operation. In 7 patients the necrosis was classified as Ficat Stage II and in 17 patients as Stage III. Eight patients showed poor results. In 6 hips with fair results, moderate progression of the necrosis was noted at 3 to 8 years postoperatively. In 5 hips showing good results, slow progression with incipient signs of arthrosis were noted 8 years after surgery. In the remaining 5 patients with excellent results, no evidence of progression was noted 9 to 14 years postoperatively. The method described is recommended for treatment in the Ficat Stage II and early Stage III, when necrosis does not yet involve the complete femoral head.  (+info)

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

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 ...

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 ...

Hip osteonecrosis occurs due to disruption of blood supply to the highest part of the thigh bone. Hip surgeon, Dr Phil Downer at Seattle Hip Surgery in Seattle, WA offers core decompression, osteotomy, arthroplasty and bone grafting
Hip osteonecrosis is really a serious condition characterised with a temporary or permanent disruption from the bloodstream supply towards the hip bone. Bone cells also require sufficient perfusion of oxygenated bloodstream because they are full of soft tissue known as marrow. Your bones are believed to get about 10 % from the bloodstream the heart pumps out, which enables for the bones to heal when broken, promote bone growth, in addition to allow removing metabolic waste material.. Osteonecrosis from the hip is really a gradual disorder that induce discomfort once the bloodstream supply towards the bone is disrupted. Its believed which more than 20,000 individuals the U . s . States are accepted towards the hospital every year for hip osteonecrosis treatment. The problem happens in individuals of every age group, races, or genders.. ...
The purpose of this investigation was to further elucidate calorimetric properties of cartilage samples from femoral head necrosis and osteoarthritis from live surgeries. The natural course of this disease is one of steady progression with eventual collapse of the femoral head, followed by secondary osteoarthritis in the hip joint. All samples showed a clear denaturation peak on the calorimetric curve. Cartilage obtained from necrotic femoral head required the lowest amount of energy for decomposition. The use differential scanning calorimetry as part of thermal analysis was a reliable method for differentiating. ...
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.
Background: The risk of post-traumatic humeral head avascular necrosis (AVN), regardless of the treatment, has a high reported incidence. In 2004, Hertel et al. stated that the most relevant predictors of ischemia after intracapsular fracture treated with osteosynthesis are the calcar length, medial hinge integrity and some specific fracture types. Based on Hertels model, the purpose of this study is to evaluate both its reliability and weaknesses in our series of 267 fractures, assessing how the anatomical configuration of fracture, the quality of reduction and its maintenance were predictive of osteonecrosis development, and so to suggest a treatment choice algorithm. Materials and methods: A retrospective study, level of evidence IV, was conducted to duly assess the radiographic features of 267 fractures treated from 2004 to 2010 following Hertels criteria treated with open reduction and internal fixation by angular stability plates and screws. The average age was 65.2 years. The average ...
What Is Avascular Necrosis Of The Hip? ,Treating Avascular Necrosis With Hip Surgery. When disease or injury prevents the blood supply from flowing freely to a bone, cells in the bone begin to die. As the bone withers, the surrounding cartilage begins to deteriorate, producing pain and other symptoms. This condition, called avascular necrosis or osteonecrosis, is most commonly found in the top of the thighbone. It usually strikes between the ages of 30 and 60, but can affect anyone at any age. The disease, which has many causes, gets worse over time.. Avascular necrosis of the hip occurs when blood flow to the top portion of the thighbone (femur) is interrupted. The affected portion of the bone consists of the head (the ball-shaped piece of bone that fits into the socket of the hip) and neck (the portion of the thighbone just below the head). When its deprived of blood, this part of the bone begins to die, breaking down and causing the cartilage on top of it to collapse.. Causes of avascular ...

Bipolar Hip rthroplasty (BHA) is one of the options for treatment of avascular necrosis of femoral head. Acetabular erosion and groin pain are the commonest complications. We postulate that these complications are secondary to improper acetabular preparation allowing for motion between BHA head and acetabulum.. The current study retrospectively evaluated 96 hips with avascular necrosis (AVN) of femoral head treated with modified BHA. Here the acetabulum was gently reamed till it became smooth and concentric to accommodate tight fitting outer acetabular cup.. The mean age of the patients was 42 years (range, 30-59). The mean follow up was 7.52 years (range, 4-12). The Harris hip score significantly improved from preoperative 39.3 (range, 54-30) to postoperative 89.12 (range, 74-96). According to Harris hip score grades the final outcome was excellent in 52 hips, good in 28 hips and fair in 16 hips. Hip and groin pain was reported in 4 hips (4%) and did not limit activity in them. Subsidence of ...

Core decompression is a procedure which entails drilling into the femoral neck, up into the necrotic area of the femoral head, to get the bone to heal faster. Theoretically, removing this central core of bone will lower the intraosseous pressure, which is thought to be one of the etiologies of the disease. When properly done, this procedure has minimal morbidity.. ...

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 number of total hip replacement (THR) is expected to increase specially in younger patients who suffer severe joint diseases. Several conditions may cause early osteoarthritis in young patients: the most frequent disorder is femoral head osteonecrosis in patients treated for acute lymphoblastic leukemia. The osteonecrosis determines a marked reduction in function and mobility due to articular degeneration and pain. Few studies have reported long-term results about implants in patients younger than 25 years of age. The purposes of this study are to: 1) evaluate life quality from a subjective point of view; 2) objectively examine clinical functionality; 3) carry out a radiographic evaluation of prosthesis integration in a group of patients under 25 who underwent a THR ...
Avascular necrosis is a disease that results from the temporary or permanent loss of blood supply to the bone. When blood supply is cut off, the bone tissue dies and the bone collapses. If avascular necrosis happens near a joint, the joint surface may collapse.. This condition may happen in any bone. It most commonly happens in the ends of a long bone. It may affect one bone, several bones at one time, or different bones at different times.. ...

Definition of Avascular necrosis staging with photos and pictures, translations, sample usage, and additional links for more information.
Avascular necrosis (AVN), also called osteonecrosis or bone infarction, is death of bone tissue due to interruption of the blood supply.[1] Early on there may be no symptoms.[1] Gradually joint pain may develop which may limit the ability to move.[1] Complication may include collapse of the bone or nearby joint surface.[1]. Risk factors include bone fractures, joint dislocations, alcoholism, and the use of high dose steroids.[1] The condition may also occur without any clear reason.[1] The most commonly affected bone is the femur.[1] Other relatively common sites include the upper arm bone, knee, shoulder, and ankle.[1] Diagnosis is typically by medical imaging such as X-ray, CT scan, or MRI.[1] Rarely biopsy may be used.[1]. Treatments may include medication, not walking on the affected leg, stretching, and surgery.[1] Most of the time surgery is eventually required and may include core decompression, osteotomy, bone grafts, or joint replacement.[1] About 15,000 cases occur per year in the ...
