Production of a radiographic image of a small or very thin object on fine-grained photographic film under conditions which permit subsequent microscopic examination or enlargement of the radiograph at linear magnifications of up to several hundred and with a resolution approaching the resolving power of the photographic emulsion (about 1000 lines per millimeter).
A progressive, malignant disease of the blood-forming organs, characterized by distorted proliferation and development of leukocytes and their precursors in the blood and bone marrow. Leukemias were originally termed acute or chronic based on life expectancy but now are classified according to cellular maturity. Acute leukemias consist of predominately immature cells; chronic leukemias are composed of more mature cells. (From The Merck Manual, 2006)

Spontaneous or traumatic premature closure of the tibial tubercle. (1/142)

A premature closure of the physis of the tibial tubercle in a young man has given rise to a shortening of the tibia, a patella alta and a reversed tibial slope of 20 degrees with clinical genu recurvatum. After a proximal open wedge tibial osteotomy all three postural deformities could be restored. The etiology of this complex deformity is discussed.  (+info)

Malunion in the lower limb. A nomogram to predict the effects of osteotomy. (2/142)

Nomograms derived from mathematical analysis indicate that the level of malunion is the most important determinant of changes in the moment arm of the knee, the plane of the ankle and alterations in limb length. Testing in five patients undergoing reconstruction showed a mean error of postoperative limb length of 2.2 mm (SD 0.8 mm), knee moment arm of 4.7 mm (SD 3.3 mm) and ankle angle of 2.6 degrees (SD 2.3 degrees). These nomograms provide the information required when assessing whether a particular degree of angulation may be accepted.  (+info)

Nerve palsy after leg lengthening in total replacement arthroplasty for developmental dysplasia of the hip. (3/142)

We reviewed 508 consecutive total hip replacements in 370 patients with old developmental dysplasia of the hip, to relate the amount of leg lengthening to the incidence of nerve palsies after operation. There were eight nerve palsies (two femoral, six sciatic), two complete and six incomplete. We found no statistical correlation between the amount of lengthening and the incidence of nerve damage (p = 0.47), but in seven of the eight hips, the surgeon had rated the intervention as difficult because of previous surgery, severe deformity, a defect of the acetabular roof, or considerable flexion deformity. The correlation between difficulty and nerve palsy was significant (p = 0.041). We conclude that nerve injury is most commonly caused by direct or indirect mechanical trauma and not by limb lengthening on its own.  (+info)

Leg lengthening over an intramedullary nail. (4/142)

Distraction osteogenesis is widely used for leg lengthening, but often requires a long period of external fixation which carries risks of pin-track sepsis, malalignment, stiffness of the joint and late fracture of the regenerate. We present the results of 20 cases in which, in an attempt to reduce the rate of complications, a combination of external fixation and intramedullary nailing was used. The mean gain in length was 4.7 cm (2 to 8.6). The mean time of external fixation was 20 days per centimetre gain in length. All distracted segments healed spontaneously without refracture or malalignment. There were three cases of deep infection, two of which occurred in patients who had had previous open fractures of the bone which was being lengthened. All resolved with appropriate treatment. This method allows early rehabilitation, with a rapid return of knee movement. There is a lower rate of complications than occurs when external fixation is used on its own. The time of external fixation is shorter than in other methods of leg lengthening. The high risk of infection calls for caution.  (+info)

Arrest of the growth plate after arterial cannulation in infancy. (5/142)

Seven children who had partial arrest of the growth plate after neonatal arterial cannulation, developed obvious skeletal changes in adolescence. Cannulation of the femoral artery produced ischaemia which led to four cases of ipsilateral shortening of the lower limb and one of partial arrest of the proximal femoral physis with subsequent coxa valga. The two arrests in the upper limb affected the humerus, ulna and radius, and the radius alone, after cannulation of the brachial and radial arteries, respectively. These late effects of cannulation are not widely appreciated, and may occur as a result of thrombosis rather than extravasation.  (+info)

Prenatal ultrasonographic diagnosis of posteromedial bowing of the leg: two case reports. (6/142)

Congenital posteromedial bowing of the leg was prenatally detected in two pregnancies, at 20 and 31 weeks of gestation. Posteromedial bowing is a rare anomaly of unknown etiology. The prenatal course, monitored by ultrasonography, and the postnatal clinical and radiographic outcomes are discussed and show a complex differential diagnosis. The initial postnatal therapy is conservative. Leg length discrepancy can eventually be treated by lengthening or epiphysiodesis on the contralateral side.  (+info)

Leg lengthening for short stature in Turner's syndrome. (7/142)

We describe ten patients with Turner's syndrome (karyotype 45, XO) who had leg lengthening for short stature. A high incidence of postoperative complications was encountered and many patients required intramedullary fixation as a salvage procedure. We discuss the reasons for this and highlight the differences between our findings and those of a similar series recently reported. In view of the considerable difficulties encountered, we do not recommend leg lengthening in Turner's syndrome.  (+info)

Missed chronic anterior Monteggia lesion. Closed reduction by gradual lengthening and angulation of the ulna. (8/142)

Two consecutive cases of chronic dislocation of the head of the radius after missed Bado type-I Monteggia lesions are presented. Reduction was successfully achieved in both patients after ulnar corticotomy, gradual lengthening and angulation of the ulna using an external fixator. Open reduction or reconstruction of the radio-ulnar capitellar joint was not undertaken. The age at injury was seven years in the older and two years in the younger patient. The time from injury to treatment was five years in the older and three months in the younger child. At follow-up, nine years after completion of treatment in the older and eight months in the younger patient, both show satisfactory movement, function of the forearm and reduction of the head of the radius. This technique may be considered in missed Monteggia lesions before open procedures on the radio-ulnar capitellar joint are undertaken.  (+info)

|p|Growing rods have been in widespread use among pediatric spinal deformity surgeons for many years. In early 2014, the FDA gave 510k approval to several implants to be used as non-fusion growing rods for the control of spinal deformity among pediatric patients. Among the approved devices, is a magnetically activated growing rod. The magnetically activated growing rod represents new technology that had not been previously available in the United States. Traditional growing rods require periodic lengthening to accommodate growth. Surgeons must select an appropriate interval for lengthening that minimizes the risk of unintended autofusion while balancing the desire to minimize the number of invasive surgeries their young patients have to endure. In general, patients undergo two to three procedures per year with these constructs. Magnetically activated growing rods can be lengthened externally with the patient awake in the outpatient setting. Furthermore, lengthenings can be done more frequently to avoid
Yesterday I had the absolute worst dental appointment of my life. It lasted for about 40 minutes and during that time I gagged almost non-stop, cried, had to be strapped down, and thought for sure that I was going to faint before it was over. If a dentist ever tells me again that I need crown lengthening for another tooth, Im going to tell him to pull the offensive tooth instead. The 2 root canals I had a few weeks ago were better than the 2 crown lengthenings yesterday (and I cried and gagged during that appointment, too -- but not nearly as much.) Part of the problem may be the strong gag reflex I have while pregnant, but it was horrific ...

An experimental model of leg lengthening was used to study the morphology of, the collagenous proteins present, and the collagen genes expressed in the regenerating tissue following 20% lengthening at four different distraction rates. At a distraction rate of 0.3 mm/day (8 weeks distraction), the regenerate consists of intramembranous bone and localized areas of fibrocartilage. At rates of 0.7 (4 weeks) and 1.3 mm/day (2 weeks), the bone that grows from the cut ends of the cortical bone is separated by fibrous tissue and cartilage is present. At 2.7 mm/day (1 week), only fibrous tissue and sparse bone are present. Type I collagen is present in the matrices around the cells expressing its mRNA and similarly, type II collagen is located around the chondrocytes. Type I collagen mRNA is expressed predominantly by the fibroblasts in the fibrous tissue, the bone surface cells and to a reduced extent by the osteocytes. Type II collagen mRNA is expressed by chondrocytes. The results suggest that osteoblasts and
Discussion: Pain relief is very often not given due importance in our (Indian) circumstances. The importance of keeping the patient free of pain, during the entire length of treatment cannot be overemphasized. This is even more vital in the early post-op period, because the patient with pain is not going to be very cooperative in the physiotherapy and mobilization. Pain also will cause the adoption of protective postures such as flexion of the knee, plantarflexion of the ankle, which later develop into contractures one of the commonest complications of the Ilizarov method. Adequate doses of non-steroidal anti-inflammatory and or narcotics must be used. The use of NSAIDs is generally discouraged because of possible, unproved deleterious effects on regenerate formation; but for a short while they can be used ...

Methods. The authors carried out a retrospective study of a series of cases regarding the treatment of patients suffering from the outcome of physeal fractures of the lower limbs, with a follow-up from 3 to 7 years depending on the place of the previous injury. 12 patients are included (4 distal tibia, 6 distal femur, 2 proximal tibia), in which the rare unfavourable outcomes are related to growth disorders. If the physeal injury affects the entire cartilage or its central portion, the limb will present length discrepancy due to shortening, whereas in case of partial damage the deformity will be an axial deviation. The treatment includes surgery of the growing cartilage and bone surgery. In the first case, medial hemiepiphysiodesis according to Blount is the treatment of choice for the correction during the growth of genu valgum. As to bone surgery, it should be performed towards the end of skeletal growth and includes osteotomies, and lengthenings, that can be performed with axial external ...

Dr.: Dr. Scharf has already given you an answer I can agree with. I would like to address the 2 last parts of your question. Today, intraoral treatments are almost always done with some form of local anesthetic so the procedure itself should not only be pain free but feeling free. Postoperatively, as the area heals sensation gradually returns and the area becomes normal feeling again. Rarely does a patient need more than over-the-counter pain meds for the usual minimal discomfort experienced after these procedures. A quality practitioner should be aware of your concerns and address them accordingly. Personally speaking, I had a crown lengthening done on myself by a colleague and dont remember it to be a painful experience. Your question about commonality of this procedure is interesting. As I am a periodontist who also does crowns (not-limited to periodontics) I can only speak from personal experience. In my office, probably less than 5% of the crowns that I do get crown lengthenings. Other ...

Introduction. The treatment of Legg-Calvé-Perthes (LCP) disease continues to be controversial with disputed and uncertain outcomes reported. The work by the Perthes Study Group reported by Herring, Kim and Browne1 dealt with children 6 years of age and older, and did not include the younger age groups. The treatment recommended for children 5 years or younger by Kim2 in a review article is non-surgical, despite reports that this group does not have a universally good outcome.3-6 It would be beneficial to be able to define accurately which children are likely to have a poor outcome, and whether any treatment can change this. Rosenfeld, Herring and Chao6 reporting on 188 hips showed that the prognosis in this age group is favourable with 80% having a good result, and that patients with a Herring lateral pillar classification B-C or C have a less favourable outcome. Of note is that all their patients were treated conservatively. Fabry, Fabry and Moens5 reported on 36 hips in 30 patients with more ...

It affects those between 2 and 18 years of age, but is most commonly seen in boys from 4 to 8 years of age. What are the Signs and Symptoms?
Bones that are too long can cause a visible or measureable length discrepancy or asymmetry when comparing the right and left upper and lower extremities. Leg length discrepancies are more commonly the source of clinical symptoms and are more perceivable by patients since the imbalance in height between sides can be detected with standing and normal walking.
Perthes disease results from a disruption of arterial irrigation of the femoral head, with the emergence of a deformity which may lead to the onset of arthritis. The
Regular exercise and physical therapy is important for the rehabilitation of the affected limb(s). Otherwise, it may result in delayed recovery and poor response to treatment. In some dogs, small lead weights are attached as ankle bracelets above hock joint to encourage early weight bearing.. Follow-up checkups are generally recommended every two weeks to ensure physiotherapy and exercises are working as desired. Overall recovery may take three to six months, thus patience is required. Dogs that are obese may undergo certain diet restrictions.. Those with Manchester terriers suffering from Legg-Calvé-Perthes Disease will be informed of the breeds genetic association with the disease, and are often recommended against breeding the dog in the future.. ...

Deep fascia is less extensible than superficial fascia. It is essentially avascular,[2] but is richly innervated with sensory receptors that report the presence of pain (nociceptors); change in movement (proprioceptors); change in pressure and vibration (mechanoreceptors); change in the chemical milieu (chemoreceptors); and fluctuation in temperature (thermoreceptors).[3] Deep fascia is able to respond to sensory input by contracting; by relaxing; or by adding, reducing, or changing its composition through the process of fascial remodeling.[4] Fascia may be able to contract due to the activity of myofibroblasts which may play a role in wound healing.[5] The deep fascia can also relax. By monitoring changes in muscular tension, joint position, rate of movement, pressure, and vibration, mechanoreceptors in the deep fascia are capable of initiating relaxation. Deep fascia can relax rapidly in response to sudden muscular overload or rapid movements. Golgi tendon organs operate as a feedback ...

Some children are born with absence or underdeveloped bones in the lower limbs e.g., congenital hemimelia. Others have a condition called hemihypertrophy that causes one side of the body to grow faster than the other. Sometimes, increased blood flow to one limb (as in a hemangioma or blood vessel tumor) stimulates growth to the limb. In other cases, injury or infection involving the epiphyseal plate (growth plate) of the femur or tibia inhibits or stops altogether the growth of the bone. Fractures healing in an overlapped position, even if the epiphyseal plate is not involved, can also cause limb length discrepancy. Neuromuscular problems like polio can also cause profound discrepancies, but thankfully, uncommon. Lastly, Wilms? tumor of the kidney in a child can cause hypertrophy of the lower limb on the same side. It is therefore important in a young child with hemihypertrophy to have an abdominal ultrasound exam done to rule out Wilms? tumor. It is important to distinguish true leg length ...

She had two additional medical treatments, one at age 10 years for additional muscle lengthening, and one at age 13, which consisted of a triple arthrodesis of her feet, hamstring lengthenings distally, and a rectus transfer at the knee. She continued to walk in the community with a combination of Lofstrand crutches and a walker. Around the house, she would walk holding on to furniture. During her high school years, she developed a mildly increased crouching gait pattern and was placed in a ground reaction ankle foot orthosis (AFO), which she disliked. With aggressive medical treatment, the infection can be eradicated, and approximately 30% of children are left with CP and mental retardation. 1 In our experience, most of these children who survive bacterial meningitis and have CP will have very severe spastic quadriplegic pattern involvement. Temporary neurologic deficits are caused by many toxic agents, with alcohol being the most commonly encountered. Alcohol almost never causes a static ...
There are assumptions that leg length discrepancy (LLD) may cause low back pain by creating pelvis obliquity and lumbar scoliosis. Although individuals with LLD develop compensatory movements in the lower limbs and pelvis during walking, few investigations have attempted to identify kinematic variables of the upper body. This study aims to gain an understanding of how simulated LLD influences three-dimensional motion of the pelvis and spine. Seven male participants were required to walk barefoot at a preferred speed. Three LLD conditions (1, 2, and 3cm) were simulated using modified pieces of high density EVA attached to the right foot. An optoelectronic motion analysis system was used to record kinematic data of the pelvis and spine (lumbar, lower and upper thoracic segments) for each condition. Differences in range of motion and patterns of movement for the pelvis and lumbar spine were minimal between barefoot and LLD conditions. These observations could be attributed to various kinematic ...
The surgical approach is required for the cleaning of necrotic bone tissues and infected soft tissues.. The resection of the infected area and the artholiths lead to a physiological shortening of the limb. The procedure that is universally recognised as being the most effective for restoring normal anatomic function is the one theorised and perfected by Ilizarov.. Thanks to a frame made up of metal rings and secured to the bone, the Ilizarov apparatus is able to carry out the bone transport of separated tissues and encourage their elongation.. The two bone segments in question can thus rely on a fixed support to guide them in the process of recomposition and subsequent recalcification..

The potential of RIS technology is explored to perform equalization over-the-air for frequencyselective channels whereas, equalization is generally conducted at either the transmitter or receiver in conventional communication systems. Reconfigurable intelligent surface (RIS)-empowered communications is on the rise and is a promising technology envisioned to aid in 6G and beyond wireless communication networks. RISs can manipulate impinging waves through their electromagnetic elements enabling some sort of a control over the wireless channel. In this paper, the potential of RIS technology is explored to perform equalization over-the-air for frequencyselective channels whereas, equalization is generally conducted at either the transmitter or receiver in conventional communication systems. Specifically, with the aid of an RIS, the frequencyselective channel from the transmitter to the RIS is transformed to a frequency-flat channel through elimination of inter-symbol interference (ISI) components at the

Legg-Calvé-Perthes disease is a childhood hip disorder which is common enough to be a significant public health problem (affects 1 in 740 boys between ages 0-14), but uncommon enough to have a sufficient number of patients from a single institution to perform a definitive prospective study comparing the results of current treatments. The present study will establish a database of prospectively identified patients with Legg-Calvé-Perthes (LCP) Disease and collect information regarding their presentation, treatment, and outcomes in the course of receiving currently available treatments..

On October 31st 2016, Halloween, our sweet Little Pony and her brothers took to the street to trick or treat. Most children, except for those littles who cant keep up (like our youngest son) run door to door in their costumes as they bob down the street. But, for some reason, our daughter wasnt. She was slow. She was walking with a limp. I wasnt sure if she fell and hurt herself earlier that day, we stopped by a few houses before returning back home. What could possibly keep this Pony from trotting down the street along with everyone else? We werent sure, but the following day it continued. And the day after that. And, you guessed it, the day after that.. A trip to the doctor led to the conclusion of what was believed to be transient synovitis. Basically, a virus was leaving her body and was trapped in a joint; causing stiffness and limping. That sounded reasonable, it would last for a few weeks. In December, the limp returned.
