Glenoplasty for recurrent posterior shoulder instability. Good results in 13 cases followed for 1-16 years.

After the failure of closed treatment, 13 shoulders in 10 patients with chronic posterior shoulder instability had an open wedge osteotomy of the collum scapulae, with interposition of an autologous graft from the iliac crest. After a median follow-up of 9 (1-16) years, there were no recurrent posterior luxations or signs of instability. All patients were satisfied, but 3 had slight pain after strenuous work. All had a full range of motion.
