The Intraoperative Pelvic Radiograph During Total Hip Arthroplasty: Is It Reliable to Estimate Leg Length?

Background: Symptomatic leg length discrepancies (LLDs) are a significant complication after total hip arthroplasty. Many surgeons incorporate an intraoperative anteroposterior pelvis radiograph, to help prevent LLD; however, obtaining a high-quality radiograph is often difficult. The purpose of this study is to evaluate the accuracy and reliability of estimating LLD using different radiographic reference landmarks on suboptimal anteroposterior …
