Children presenting with Perthes' disease before their sixth birthday are considered to have a good prognosis. We describe 166 hips in children in this age group. The mean age at onset of the disease was 44 months (22 to 72). Mild forms (Catterall I and II) were treated conservatively and severe forms (Catterall III and IV) either conservatively or operatively. The aim of the former treatment w...

Legg-Calvé-Perthes disease (LCPD) is an idiopathic osteonecrosis of the femoral head with variable complications and resultant deformity of the femoral head and osteoarthritis. Suggested risk factors are acetabular retroversion, obesity, latitude, hyperactivity, and coagulopathy. The most commonly applied classification is based on radiolucency in the lateral pillar of the femoral head, which i...

Classifications of Legg-Calvé-Perthes disease (LCPD) may be divided into three categories: those defining the stage of the disease, those attempting to prognosticate outcome, and those defining outcome. Although Arthur Legg MD [13], Jacques Calvé [2], and Georg Perthes MD [17] share credit for their descriptions of the disease published between 1909 and 1910, according to Wenger and Pandya, Hen...

Upper femoral osteotomy is a recognised treatment for selected patients with Perthes' disease. The results of this procedure were investigated at skeletal maturity in 44 patients (48 hips). The indication for operation was Catterall group II, III, and IV hips with 'head-at-risk' signs. Harris and Iowa scores were calculated clinically, and each hip was assigned radiographically to one of the fi...

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...

Background In a previous study, we reported clinical and radiographic results of our modified Salter innominate osteotomy technique in 16 hips affected by Legg-Calvé-Perthes disease (LCPD) with an average follow-up of 31.8 months. In this study, we present the long-term results of the osteotomy in LCPD patients followed until physeal closure. Methods Thirty hips of 29 patients were followed u...

The clinical importance of dysplasia epiphysealis capitis femoris (Meyer dysplasia) is that it is easily mistaken for Legg-Calve-Perthes disease, leading to unnecessary diagnostic procedures and treatments. After a review of 578 children (619 hips) with Legg-Calve-Perthes disease, 17 children (27 hips) in whom both the clinical and radiologic pattern was obviously different could be found and a...

The natural history of Legg-Calvé-Perthes disease (LCPD) in children older than 8 years is usually poor without treatment. The treatment goal is to prevent deformity and incongruity of the hip by achieving a stable spherical femoral head in a deep, congruent, sharp-edged acetabulum, with a good range of hip movement at skeletal maturity. Lateral shelf acetabuloplasty in LCPD can increase the co...

Eight cases of disseminated herpes simplex infection unassociated with infantile eczema have been found at autopsy during the period September, 1957, to April, 1958. All but two of these were grossly malnourished. Herpetic stomatitis is very much more common than is generally appreciated. Routine studies carried out in our virus laboratory have revealed that many of the more severe and atypical...
