Frequency and Characteristics of Posterior Labral Injuries in Operative Acetabular Fractures Treated Through a Posterior Approach: A Prospective Observational Study.

This study describes the high rate (89%) of posterior labral injuries in posterior wall fractures, the most common injury pattern being a detachment of the posteroinferior labrum. Labral injuries in acetabular fractures may have important clinical implications and this study is the first to identify the frequency and characteristics of these injuries. Further studies should assess the relationship between labral injuries, treatment strategies, and the progression to post-traumatic osteoarthritis.
