Scapulothoracic penetration of a Beath pin: an unusual complication of arthroscopic Bankart suture repair.

The arthroscopic Bankart suture repair technique is an alternative to open procedures that control anterior shoulder instability. A case is presented in which a Beath pin traveled through the scapula and penetrated the scapulothoracic articulation during arthroscopic Bankart repair. The authors caution that strict adherence to Morgan's technique should minimize complications with this procedure.
