Morphometric Variations in the Hip Joint: Implications for Total Hip Arthroplasty

Author(s): Crizel Rosane*

Morphometric variations in the hip joint play a critical role in the planning and execution of total hip arthroplasty (THA), influencing both surgical outcomes and implant performance. This review examines the anatomical diversity of the hip joint, focusing on variations in the acetabulum and femur that can impact the success of THA procedures. By analyzing recent studies utilizing imaging techniques such as computed tomography (CT), magnetic resonance imaging (MRI), and three-dimensional modeling, we highlight key morphometric parameters—including acetabular version, femoral head shape, and bone stock quality—that are crucial for optimizing implant alignment and positioning. Understanding these variations is essential for tailoring surgical approaches and selecting appropriate implants, thereby minimizing complications such as dislocation, implant loosening, and poor functional outcomes. Additionally, we explore advancements in preoperative planning tools and techniques aimed at accommodating these anatomical differences. This review provides insights into how a detailed understanding of hip joint morphometry can enhance surgical precision, improve patient-specific outcomes, and contribute to the overall success of total hip arthroplasty.
