title: Arthroscopic posterior shoulder stabilization with an iliac bone graft and capsular repair: a novel technique.
abstract: Several surgical approaches have been described for the treatment of recurrent posterior shoulder instability. Many authors have performed posterior bone block procedures with good results not only in the presence of glenoid bone loss or dysplasia but also in the case of capsular hyperlaxity and poor soft-tissue quality. Open techniques often require an extensive approach with the disadvantage of a poor cosmetic result and possible insufficiency of the deltoid muscle. Furthermore, the treatment of concomitant pathologies and the correct placement of the bone graft are difficult. Therefore we describe an all-arthroscopic posterior shoulder stabilization technique with an iliac bone graft and capsular repair that is intended to improve the pre-existing open procedure. The key steps of the operation are the precise placement and screw fixation of the bone block at the posterior glenoid under arthroscopic control and the subsequent posterior capsular refixation and plication using 2 suture anchors to create an extra-articular graft position.
