Legg-Calve-Perthes Disease

Legg-Calve-Perthes disease is self-limited, but its course may result in irreversible mechanical impairment of the hip. The clinical observation and analysis were carried out on 83 cases of Legg-Calve-Perthes disease in the Department of Orthopaedic Surgery, Presbyterian Hospital, Taegu.

Subtrochsnteric varization osteotomy with open wedge technic was performed for the Legg-Calve-Perthes disease patients of 6 years to 9 years of age. Open wedge technic is less complicated with unwilling effect of postoperative leg shortening than closed wedge technic, but has seldom performed for the patients over 5 years of age because of possible delayed or nonunion of osteotomy site. Authors trial of this technic in a older patient(6 to 9 years of age) showed excellent post-operative result with noneventual post-operative course including delayed or nonunion.

Although many reports have been published about Legg-Calve-Perthes disease, developmental dysplasia of hip, it is difficult to gain a satisfactory results in treatment. We experienced 9 year-old girl with ipsilateral neglected DDH combined with contralateral LCPD, and treated with Klisic operation for DDH and femoral valgus osteotomy for hinged abduction of LCPD. We gained satisfactory results and report this rare case.

PURPOSE: To know the proportional contribution of causative factors to the femoral shortening in Legg-Calve-Perthes disease. MATERIALS AND METHODS: In twenty piglets, 4 to 5 weeks old, vascular supply to the capital femoral epiphysis was interrupted by ligating the femoral neck containing the epiphyseal artery. RESULTS: Mean femoral shortening in piglets sacrificed at 4 weeks after devascularization was 7.4 mm. In detail, the shortening was 2.5 mm (34%) in the epiphysis and 4.9 mm (66%) in the neck and diaphysis. Mean femoral shortening in piglets sacrificed at 8 weeks after operation was 12.1 mm. The distribution of shortening was 4.6 mm (38%) in the epiphysis and 7.5 mm (62%) in the neck and diaphysis. Mean femoral shortening in piglets sacrificed at 20 weeks after operation was 20.7 mm. The distribution of shortening was 4.0 mm (19%) in the epiphysis and 16.7 mm (81%) in the neck and diaphysis. CONCLUSION: We determined the proportional contribution to the residual shortening according to the causative factors.

This report describes simultaneous bilateral Legg-Calve-Perthes disease (LCPD) development in four-year-old identical male twins. Moreover, the twins showed head involvement patterns with mirror symmetry. We included a review of the literature on this rare condition and discussed the genetic risks associated with LCPD.

PURPOSE: The purpose of this study was to determine the relative contributions made by pathoanatomical factors responsible for femoral shortening in Legg-Calve-Perthes disease (LCPD), and to devise a method of reducing the amount of residual shortening based on a better understanding of its pathoanatomy and developmental pattern in LCPD. MATERIALS AND METHODS: We measured shortening of three anatomical components, namely, the femoral epiphysis, neck, and diaphysis on the teleoroentgenograms of 106 LCPD patients, comprised of 35 children with active disease, 24 in the healing stage, and 47 at skeletal maturity. RESULTS: The proportional contributions made by these 3 anatomical components to residual shortening at skeletal maturity were; 20% by the epiphysis (epiphyseal flattening), 53% by the neck (physeal growth retardation), and 27% by the diaphysis (underuse atrophy). These contributions differed according to disease stage and shortening severity. Mean diaphyseal shortening was 3.9 mm at skeletal maturity, but this increased to 5.8 mm when only patients with severe shortening (20 mm or more) were included. CONCLUSION: Our findings suggest that diaphyseal shortening is likely to be minimized by the implementation of limb exercise programs.
