Massive graft resorption after iliac crest allograft reconstruction for glenoid bone loss in recurrent anterior shoulder instability.

Abstract：

INTRODUCTION:Donor site morbidity constitutes the most prevalent source of complications during anatomic glenoid reconstruction. Therefore, the aim of this study was to evaluate the clinical and radiologic results of arthroscopic anatomic glenoid reconstruction using an allogenic, tricortical iliac crest bone graft for glenoid bone loss in recurrent anterior shoulder instability. MATERIALS AND METHODS:Ten patients [one female/nine male, mean age 31.9 years (range, 26-40)] underwent allogenic iliac crest bone grafting and were evaluated clinically [range of motion, subscapularis tests, apprehension sign, Constant score (CS), Rowe score (RS), Walch-Duplay score (WD), Western Ontario Shoulder Instability Index (WOSI), Subjective Shoulder Value (SSV)] and radiographically [3-dimensional computed tomography (CT) scans]. RESULTS:After 23.2 months, the CS averaged 90 points (range, 84-98), RS 83 points (range, 50-100), WD 81 points (range, 50-100), WOSI 72% (range, 41-86) and the SSV 83% (range, 70-95). All patients showed a free range of motion and intact subscapularis muscle function. The apprehension sign was positive in three patients (30%) with a recurrent subluxation in one patient (10%). The glenoid surface area increased significantly from 84.4% (range, 73.5-92.1) preoperatively to 118.4% (range, 105.6-131.2) after surgery, while the glenoid defect was significantly reduced from 16.2% (range, 9.2-26.5) to 0.6% (range, 0-1.6). One year postoperative, total resorption of the allografts was observed with a glenoid surface area of 86.6% (range, 76.4-98.0) and corresponding increase of the glenoid defect to 14.0% (range, 2.9-23.6). CONCLUSION:Arthroscopic glenoid reconstruction using an iliac crest bone allograft achieves satisfactory clinical results and glenohumeral stability during a short-term follow-up. However, this procedure was not observed to accomplish an anatomic reconstruction of the glenoid concavity due to excessive graft resorption. LEVEL OF EVIDENCE:Level IV, case series, therapeutic study.
