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.

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.

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.

237 patients with Legg-Calve-Perthes disease were treated during past 12 years. Among them, a comparative study was done for 87 patients who were followed up over 2 years. They were analyzed according to Catteralls classification and divided into a group of conservative treatment and of surgical treatment. 74 patients were boys and 13 patients were girls and the ratio of boys to girls was 5.7 to 1. The mean age was about 6.9-year-old. Bilateral involvement was observed in 6 patients. According to Catterall classification. 1(1.1%) was classified as group I, 27(29.0%) as group II, and 36(38.7%) as group III, and 29(31.2%) as group IV. According to assessment by Harrison et al., satisfactory result was achieved in 63.2% of cases of conservative treatment and 34.3% of cases of operative treatment. The measurement of epiphyseal quotient and femoral head sphericity(by Mose) were considered meaningful methods for assessing the result of the treatment. The most frequent one of “Head-at-Risk” factors was lateral subluxation of femoral head. The result of treatment was not always coincided with the classification by Catterall. In bilateral involvement, the first affected hip had better prognosis than contralateral one.
