Myelodysplasia. The influence of the quadriceps and hip abductor muscles on ambulatory function and stability of the hip.

In an analysis of motor function, ambulatory function, and hip stability in sixty-five patients with myelodysplasia, four motor-function groups based on the strength of the quadriceps and hip abductor muscles were identified. Retrospectively, it was evident that based on these groups, it would have been possible to predict which hips would remain stable, what level of ambulatory function the patients could achieve, and whether treatment to reduce and stabilize the hips was indicated. Fifty-seven of fifty-eight hips in the twenty-nine patients with functioning quadriceps muscles but non-functioning hip-abductor muscles were either subluxated or dislocated. Thirty-nine of the remaining forty-six patients with functioning quadriceps muscles could walk. In this series, three operative procedures were used to treat hip subluxation: varus osteotomy, varus osteotomy combined with iliopsoas transfer, and iliopsoas transfer alone. One shelf procedure was also done. Varus osteotomy was the best procedure for hip subluxation while posterior iliopsoas transfer, either alone or in combination with a varus osteotomy, was of questionable value. Treatment of hip instability (subluxation or dislocation) in patients without quadriceps function was not necessary.

The changing signs of congenital hip dislocation.

A total of 36 patients (42 hips) with frank congenital hip dislocation were studied. The initial clinical and x-ray signs were evaluated according to the age at which the patient was first seen and treatment started.

Congenital hip dislocation: before and after walking age.

Residual morbidity from congenital dislocation of the hip is for the most part preventable. Prevention is possible, however, only by establishing the diagnosis early and undertaking treatment which leads to stable reduction and avoids complications. To attain these goals, hip examination whould be a routine part of all newborn care. When dislocation is found in a newborn and early treatment initiated, the anatomic abnormalities are minimal, the dislocation is rasily reduced, and the treatment is simple. When diagnosis and treatment are delayed, the soft-tissue and bony abnormalities become established and therapy becomes more complicated.

Changes in tibiotalar area of contact caused by lateral talar shift.

A carbon black transference technique was used to determine the contact area in twenty-three dissected tibiotalar articulations, with the talus in neutral position and displaced one, two, four, and six millimeters laterally. The greatest reduction in contact area occurred during the initial one millimeter of lateral displacement, the average reduction being 42 per cent. With further lateral displacement of the talus the contact area was progressively reduced but the rate of change for each increment of shift was less marked.

Congenital dislocation of the hip. Use of the Pavlik harness in the child during the first six months of life.

From 1968 to 1972, twenty-three infants under six months old with twenty-seven dislocated hips were treated with a Pavlik harness. All the dislocations except three were successfully reduced. Only one child required hospitalization. All the patients were followed for more than two years. All but three of the hips were clinically and roentgenographically normal at follow-up, and none had avascular necrosis. In infants, the Pavlik harness successfully utilizes the principle of reduction in flexion, avoiding forced abduction.

Congenital dislocation of the hip associated with central core disease.

Central core disease is a congenital, non-progessive myopathy with proximal muscle weakness most prevalent about the pelvic girdle. Including out two patients there have been seven recorded cases of congenital hip dislocation associated with central core disease in children. Initial and recurrent contractures about the hip and knee should suggest the possibility of central core disease. However, the definitive diagnosis can only be made by muscle biopsy.

Treatment of steroid induced osteocartilagenous separation of the distal femur. A case report.

A 20-year-old Negro man, with a history of febrile disease, was diagnosed to have noncaseating granulomatous inflammatory disease. He was placed on Prednisone therapy for several years. Subsequently, he was found to have osteocartilagenous separation of the lateral condyle of the right femur. This was preceded by symptoms of recurrent pain and swelling of the knee. The surgical treatment employed was anatomic repositioning of the osteocartilagenous fragment with an interposed corticocancellous graft. The postoperative management was non weight-bearing for a 6 months' period and a cast brace. The patient was symptom free at 20 months' follow-up.
