[Proximal femur remodeling after proximal femur varus-derotational osteotomy in treatment of developmental dysplasia of the hip].
The aim of this paper was to assess proximal femur remodelling after proximal femur varus-derotational osteotomy in treatment of developmental dysplasia of the hip up to skeletal maturity. The analysis included 48 osteotomies performed in 33 children between 1st and 10th year of life. The follow-up period was on average 12 years. Supported by statistical evaluation the analysis showed persistent increase of the neck-shaft angle after proximal femur varus-derotational osteotomy, especially in the younger age groups. It also correlated strongly with the amount of varus fixed at the time of operation. On other hand femoral antetorsion corrected during surgery remained unchanged till skeletal maturity.
