We studied radiographs of 125 children (105 boys, 20 girls) with unilateral Legg-Calvé-Perthes' disease to examine the epiphyseal development of the femoral head in the contralateral (unaffected) hip. The epiphyseal height (EH) and width (EW) of the unaffected hip were measured on the initial anteroposterior pelvic radiograph. In 109 of the patients (87.2%) the EH was below the mean for normal ...

BACKGROUND Recent reports support the hypothesis that thrombophilia plays an important role in the pathogenesis of Perthes disease (PD) and the objective of this report is to show evidence of the role of protein C deficiency in the etiology of PD, based on a meta-analysis of current scientific literature. MATERIAL AND METHODS Studies were selected in all languages over the last twenty years (...

In this study, clinical and radiological results were evaluated in patients with Legg-Calve-Perthes disease treated with Salter pelvic osteotomy. Between 2004 and 2008, 16 patients underwent a Salter osteotomy as treatment for Legg-Calve-Perthes disease (15 male, 1 female; 10 right hip, 6 left hip). The mean age at the time of surgery was 8.1 +/- 1.4 (range: 6 to 10) years. Surgical indications...

We report a six year old male with mental retardation, postaxial polydactyly and syndactyly, atrichia congenita totalis, severe seborrhoeic dermatitis, recurrent staphylococcal skin sepsis, and Perthes' disease of the hip. His birth may have resulted from an incestuous mating.

In this paper we wish to emphasise the danger of avascular necrosis of the capital femoral epiphysis arising as a late complication of osteomyelitis of the intertrochanteric region. This necrosis is primarily aseptic and is believed to follow interference with the vulnerable vascular channels supplying the capital femoral epiphysis rather than spread of infection into the joint. If, however, th...

Some 2500 children with congenital dislocation of the hip were treated at the Orthopaedic Hospital of the Invalid Foundation over the period 1954 to 1974 and have been regularly followed up to the end of growth. One of us (Laurent 1953) had already observed that the vulnerability of the femoral head had often led to changes resembling Perthes’ disease. In 1957 preliminary traction and adductor ...

Background and purpose - Different radiographic classifications have been proposed for prediction of outcome in Perthes disease. We assessed whether the modified lateral pillar classification would provide more reliable interobserver agreement and prognostic value compared with the original lateral pillar classification and the Catterall classification. Patients and methods - 42 patients (38 bo...

A 14 year old boy presented with a painful hip, initially attributed to Perthes' disease although it is uncommon in teenagers. Subsequent investigation showed that the underlying pathology was non-Hodgkin's lymphoma.

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...
