Abstract:
PURPOSE: The purpose of this study was to evaluate the long term results of performing femoral varus osteotomy (FVO) for the treatment of Legg-Calve-Perthes disease (LCPD). MATERIALS AND METHODS: We selected 35 LCPD patients who received FVO and they were followed up to the time their skeletons' matured. The inclusion criteria were patients in a fragmentation stage, the patients were in Catterall group III or IV, and the patients underwent a teleoroentgenographic examination at the time of full skeletal maturity. RESULTS: The radiological outcome at the time of skeletal maturity was assessed using Stulberg's classification. The final results were 4 hips in class I, 17 hips in class II, 13 hips in class III, one hip in class IV and none in class V. The satisfactory results (good+fair hips) were 34 hips (97%). Significant shortening (>10 mm) was observed in 12 hips (34%). In 35 patients, 5 (14%) had same leg length (less than 2 mm difference), 27 (77%) had shortening of 2 mm or more, and 3 had lengthening of 2 mm or more in the operated limb. Of these 12 patients with significant shortening, only 3 patients (9%) showed shortening of 21 mm or more. CONCLUSION: FVO is a reliable method for managing LCPD in patients who are in Catterall group III or IV and who are in the fragmentation stage of disease.
