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.
