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

ABSTRACT:

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 pelvis radiographs.

Material and methods

We obtained 2 pelvis Sawbones models with attached femurs and created a true shortening of the left femur of the experimental model by 7 mm. We then obtained a series of radiographs manipulating each model in standardized increments for a total of 66 different permutations of suboptimal radiogra
