Avascular necrosis (AVN) is a known complication during the management of developmental dysplasia of the hip (DDH). It has the potential to alter the growth of the head or acetabulum and prevent the best outcomes. While past literature has evaluated the risks of AVN and strategies to avoid it, studies on the impact of AVN on the outcomes are scarce.

From the Department of Orthopaedic Surgery, Keck Medical Center of the University of Southern California, Los Angeles, CA (Ihn, Chung, Lovro, Patterson, Christ, and Heckmann), the Department of Orthopaedic Surgery, Mayo Clinic, Rochester, MN (Chen), the Department of Orthopaedic Surgery, University of Pittsburgh, Pittsburgh, PA (Tucker), and the Department of Radiology, Keck Medical Center of the University of Southern California, Los Angeles, CA (White, and Hwang).
Introduction: Vascular injury during acetabular screw fixation is a life-threatening complication of total hip arthroplasty. This study uses three-dimensional computed tomography to (1) measure absolute distance from the external iliac artery (EIA) to the acetabulum, (2) determine available bone stock along the EIA path, and (3) create a novel acetabular vascular risk map.
Methods: A retrospective radiographic study was conducted using three-dimensional CT.
Intraprosthetic Dislocation Following Dual Mobility Total Hip Arthroplasty: A Retrieval Analysis Study.

Department of Orthopaedic Surgery, Fiona Stanley Fremantle Hospitals Group, Murdoch, Western Australia, Australia.
Background: Dual mobility (DM) implants in total hip arthroplasty provide excellent range of motion with low dislocation rates. A complication of this design is intraprosthetic dislocation (IPD), where the polyethylene (PE) liner dissociates from the femoral head. In older designs, IPD occurred due to a small head size and late PE wear with head-capture-mechanism failure.

Cell salvage (CS) is a tool where autologous blood lost during surgery is collected and recycled with anticoagulation, centrifugation to separate red blood cells, and washing to be reinfused back to the patient. The purpose of this study was to investigate our experience with CS in pelvic and acetabular surgery and its relationship to perioperative transfusion requirements.
