PINCER MORPHOLOGY IS NOT ASSOCIATED WITH DEVELOPMENT OF HIP OSTEOARTHRITIS WITHIN 10 YEARS; A NATIONWIDE PROSPECTIVE COHORT STUDY (CHECK)

Abstract

Purpose: Pincer morphology is an overcoverage of the acetabulum relative to the femoral head (figure 1). During motion of the hip, this might lead to an abutment between the acetabular rim and femoral head-neck junction, a process referred to as pincer-type femoroacetabular impingement. This abnormal contact between the femoral head and acetabulum might potentially lead to damage of the labrum and articular cartilage. However, to date, results on the relationship between pincer morphology and hip osteoarthritis (OA) have been conflicting and previous prospective cohort studies typically did not find an association.
