Both Decreased and Increased Relative Acetabular Volume Are Associated with Increased Hip Arthritis in an Osteological Review of 1090 Hips

Abstract

Purpose: Recently, there has been considerable interest in quantifying the associations between bony abnormalities about the hip joint and osteoarthritis. The relationships between acetabular undercoverage, acetabular overcoverage, and femoroacetabular impingement (FAI) with hip joint osteoarthritis (HOA) remain controversial. Methods: 545 cadaveric skeletons (1090 hip joints) from the Hamann-Todd osteological collection were obtained. Femoral head volume (FHV), acetabular volume (AV), the ratio between femoral head volume and acetabular volume (FHV/AV), …
