INTRODUCTION: The purpose of this study was a detailed analysis of clinical and radiological results following open fixation of acute-traumatic, displaced anterior glenoid rim @entity174 with bioresorbable pins. MATERIALS AND METHODS: This retrospective study included 17 @entity1 with @entity154 sizes >= 20  %, as directly measured in preoperative sagittal en face CT. The mean @entity154 size was 25.3  % (20-35, SD 4.7). Two or three polylactid pins were used for fixation. Mean age of @entity1 at the time of surgery was 50.1  years (27-71). The mean follow-up period was 6.2  years (2.0-11.1). Follow-up included comprehensive objective and subjective evaluation of shoulder function as well as standard radiographs. RESULTS: The majority of 15/17 @entity1 obtained good or excellent clinical results according to the absolute and normalized Constant score, the Rowe score, the Oxford shoulder score, the simple shoulder test, the shoulder @entity158 and disability index and the subjective shoulder value. Quality of life (SF-36) showed reference values. Mean or subitem values of all outcome measures did not differ from the contralateral, uninjured side. Radiographically, all @entity174 healed without secondary dislocation. Radiological signs of @entity625 developed in two @entity1 and progressed in two other @entity1 . There were no @entity532 . No @entity1 experienced glenohumeral instability or had to undergo revision surgery. CONCLUSIONS: Bioresorbable pin fixation is a feasible and safe method of osteosynthesis for anterior glenoid rim @entity174 up to a @entity154 size of about 35  % and enables immediate active range of motion. Good or excellent clinical outcome can be expected and glenohumeral stability is reliably restored. The most common mid- and long-term complication is occurrence or progression of @entity571 . The major benefits of bioresorbable pin fixation are redundancy of implant removal, minimal risk of @entity532 and early functional rehabilitation.
