Abstract:
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.
