Greater blood loss and prolonged operative duration have been reported in patients undergoing hip arthroplasty via a transtrochanteric approach. Furthermore, trochanteric nonunion rates, ranging from 5% to 17%, have discouraged surgeons from using the transtrochanteric approach in routine primary arthroplasty. However, trochanteric osteotomy still has an important role in hip arthroplasty in cases of preexisting developmental hip dysplasia with superior subluxation, revision arthroplasty, specifically with acetabular component revision in the face of well-fixed femoral component, and recurrent dislocation without component loosening or malalignment, in which the trochanter can be advanced for abductor tightening.This study reports the clinical outcomes of trochanteric hook plate fixation in a cohort of ten patients.
