Glenoid fractures

Abstract

The prevalence of anterior glenoid rim fractures has been reported from 22% of patients after first-time anterior shoulder dislocation and up to 73% of patients in recurrent instability. These fractures are associated with failures after arthroscopic Bankart repairs. Fractures of anterior glenoid correspond to type IA in the Ideberg classification. There exist, as always, either conservative or surgical treatment options. The good results achieved while operating acute dislocations and the worse outcomes of chronic lesions repairs are reflected in the literature. Treatment includes open or arthroscopic repair with use of either suture anchors or metal cannulated and bioabsorbable screws. Arthroscopic approach is recommended for that purpose and has some advantages. These are intra-articular visualization of the reduction, preservation of the bony fragment blood supply, decreased soft-tissue dissection, etc. Usually, accessory anteroinferior portal through the inferior part of the subscapularis tendon is used. Overall, the results of arthroscopic treatment of anterior glenoid fractures are satisfying. A redislocation rate occurs from 0 to 6.6% in either acute or chronic lesions. The return to activity is possible in most of the cases.
