Scapular (glenoid and acromion) osteotomies for the treatment of posterior shoulder instability: technique and preliminary results.

ABSTRACT:

Background

Static and dynamic posterior shoulder instability (PSI) are associated with a higher, more horizontal acromion providing poor posterior humeral head (HH) coverage. The current surgical treatment yields unsatisfactory long-term outcomes with high recurrence rates in dynamic and failure to restore joint concentricity in static PSI. We hypothesized that restoring physiological acromio-glenoid relations would prevent recurrence of dynamic and positively influence static PSI.

Methods

This study reports the outcome after a "scapular (acromion and glenoid) corrective osteotomy for posterior escape procedure in 9 consecutive patients at a minimum 2-year follow-up. One patient had static, 2 had dynamic and 6 had combined PSI. Osteotomies to restore normal scapular bony ana
