Technical considerations in total hip arthroplasty after femoral and periacetabular osteotomies

The purpose of this article is to outline key technical considerations in the performance of total hip arthroplasty after common osteotomies of both the proximal femur and acetabulum. Attention is called to anatomic variation, both innate and incurred. After a femoral osteotomy, specific focus should be placed on incision selection, residual hardware management, abductor handling, and proper version establishment. After a periacetabular osteotomy, similar concern should be granted to cup position and fixation. Results of total hip arthroplasty after common osteotomies are also reviewed and importance of these issues highlighted.
