There is growing evidence that patients with lumbar spine fusion are at greater risk for postoperative dislocation following total hip arthroplasty. The purpose of this study is to review one author's experience with the modified direct lateral approach in patients with prior or subsequent lumbar spine fusion and total hip arthroplasty. Our IRB approved clinical database was queried for all primary total hip arthroplasties performed by the senior author from 1/1/2004 to 12/31/2016. All were performed via a modified direct lateral approach. Of these 1902 hips (1656 patients), 59 were identified in our medical records as patients who had a prior spine fusion or a spine fusion following THA. The extent of fusion was identified and reported. Radiographs were reviewed for acetabular position (abduction and anteversion) and leg length discrepancies. Records were reviewed and patients were contacted to determine if there were dislocations.Introduction
