Glenoid osteotomy

Abstract

Glenohumeral instability is a common disease with the incidence rate of 56 per 100 000 people per year. On the other hand, posterior shoulder instability (PSI) affects only 2-4% of patients suffering from glenohumeral instability. Although there is a variety of therapeutic options for management of PSI, conservative approach remains a first-line treatment with 60-90% success rate. Following unsuccessful conservative treatment, surgical approach should be considered. One of the potential surgical procedures is glenoid osteotomy, which could be beneficial in group of patients with atraumatic and symptomatic instability with increased glenoid retroversion (<20o), or glenoid dysplasia following unsuccessful conservative or soft tissue repair. Due to limited indications and potential complications of the glenoid osteotomy, it should be performed after careful preoperative planning by experienced surgeons.
