Bennet Lesion
摘要
Bennet lesion is an extra-articular ossification of the posteroinferior glenoid. First described by Bennet in 1941 and later redefined by Lombardo in 1977, its origins are attributed to either traction of the posterior band of the inferior glenohumeral ligament or humeral head impingement. The lesion is linked to repetitive throwing motions and is commonly asymptomatic, though its role in shoulder pain remains debated. Epidemiological studies highlight a higher prevalence among baseball players, with rates of 21–32.2% in different populations. Despite its presence in the general population, it is more frequent in athletes, particularly those with long playing histories. Diagnosis is challenging due to its association with other shoulder pathologies, complicating the identification of symptoms’ true cause. Treatment typically begins conservatively, with surgery considered after 3–6 months if necessary. The optimal surgical approach and the necessity of removing the Bennet lesion itself remain unclear, emphasizing the importance of accurate diagnosis for effective treatment.
