CORR Insights^®: Complete Circumferential Osseous Extension in the Acetabular Rim Occurs Regardless of Acetabular Coverage

Excerpt

Acetabular labral ossification, a condition resulting from labral damage, is not generally well-known among orthopaedic surgeons. From what I found, Ninomiya and colleagues [4] first described a patient with enchondral ossification of the labrum in 2000. More than a decade later, Corten and colleagues [2] postulated in a case series that this rim ossification was bone apposition in the presence of preexisting pincer impingement in which ossification began in the subperiosteal region, subsequently either displacing or encasing the labrum. Recently, my colleagues and I reported on the demographics and outcomes of patients with femoroacetabular impingement (FAI) associated with labral ossification compared to FAI cases in which no ossification was present [1]. …
