Does valgus femoral osteotomy improve femoral head roundness in severe Legg-Calvé-Perthes disease?
VFO appears to help the deformed femoral head in the fragmentation stage to remodel to fit the acetabulum.
The renoprotective benefit of an obtained attenuation of intermediate parameters is modified by other factors. Further optimization of renoprotective therapy requires identification of such factors and explicit consideration of therapeutic efficacy on intermediate parameters as well as hard end points.
