arthroplasty (THA) via a posterior approach and to investigate anatomic variables …

Background Total hip arthroplasty (THA) patients with limited lumbar flexion (LF) have
increased rates of dislocation. An instrumented spinal fusion is a well-recognized cause …

Background Recent research has demonstrated that patients with reduced pelvic mobility
