Functional deficits persist in a significant percentage of total hip arthroplasties (THA), leading to patient dissatisfaction. Spinal stenosis is a leading cause of chronic disability and lower extremity weakness. Although previous studies have evaluated the potential benefit of THA on back pain, none have reported the effects of spine disability on functional outcomes and patient satisfaction with THA. 244 primary THAs (233 patients) with minimum 2-year follow-up rated their satisfaction, return to activity, and standard hip outcomes using the Oxford Hip Score (OHS). History of lumbar spine pain, lumbar surgery, and daily activity limitations was documented and an Oswestry Disability Index (ODI) score was calculated.Introduction
