It has been suggested that Perthes' disease is more prevalent in urban areas, and that the risk increases with deprivation. We present the findings of a preliminary analysis of Perthes' disease in Northern Ireland, which is shown to have one of the highest national annual rates of incidence in the world (11.6 per 100000). Of the 313 children diagnosed over a seven-year period, 311 were allocate...

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...

BACKGROUND AND OBJECTIVES Perthes disease is a childhood precipitant to osteoarthritis of the hip, for which the etiology and mechanism are unknown. There is mounting evidence to suggest a vascular insult is responsible for disease, and it is suggested that this may have long-term implications for the vascular health of affected individuals. This study sought to use ultrasound measures to inves...

BACKGROUND The prognosis for children in whom Legg-Calvé-Perthes disease develops before the age of six years was initially reported to be good, but later studies demonstrated a less favorable prognosis. To assess the natural history of this condition in this age group, we reviewed a large cohort of children who had received minimal treatment for the disease. METHODS The medical records and r...

Premature closure of the growth plate of the femoral capital epiphysis associated with limitation of abduction and gluteal insufficiency is described. The indications for trochanteric advancement and the results obtained in the late treatment of Perthes' disease and of congenital dislocation are discussed. Nine hips treated after Perthes' disease had satisfactory results, in that all were impro...

Radiographs of 155 Indian children were examined to identify the acetabular changes which occur in Perthes' disease. These changes included osteoporosis of the acetabular roof, irregularity of contour, premature fusion of the triradiate cartilage, hypertrophy of articular cartilage and changes in dimensions. These changes tended to be more marked in older children and when more than half of the...

PURPOSE "Hinge abduction" is a complication of Perthes' disease caused by impingement of the extruded superolateral portion of the femoral head against the lateral lip of the acetabulum. Catterall first described femoral valgus extension osteotomy (VGEO) to treat this condition. We report the results of this operation in 16 cases of Perthes' disease with "hinge abduction". METHODS Sixteen hip...

Legg-Perthes disease (osteochondritis deformans) is an aseptic necrosis of the capital femoral epiphysis. The clinical and radiographic features of Legg-Perthes disease have been well documented (Goff, Shutkin, and Hersey, 1954; Kemp and Boldero, 1966) but apart from Molloy and MacMahon's Massachusetts study (1966) few epidemiologic investigations have been reported. A genetic component to the ...
