Femoral osteotomy was associated with improved sphericity in severe Perthes'; leaves open whether RCTs would confirm benefit or change practice.
Does femoral osteotomy improve the development of congruous spherical femoral heads in severe Perthes' disease compared to no treatment?
Femoral osteotomy significantly improves the development of congruous spherical femoral heads in severe Perthes' disease compared to no treatment.
