Following primary iliac crest graft glenoid augmentation, patients with shoulder instability showed good results through 19 years follow-up and the method fostered anatomic reconstructions, according to this study.
“Glenoid rim reconstruction with iliac crest graft was equally effective for patients with primary repair and for failed previous stabilization,” Viviane Steffen, MD, wrote in the abstract. “It offered the advantage of an anatomic reconstruction with a comparatively good long-term preservation of the joint line.”
In 48 patients with mean 9.2 year follow-up, the mean Oxford Shoulder Instability Score was 18.1 points. Initially, 15% to 25% of patients had glenoid defects, based on the abstract. Eight of 43 patients reported residual pain, 3 patients had perceived instability, and 1 patients required re-intervention after a dislocation.
Steffen and colleagues noted in 2 patients a relevant fatty infiltration of the subscapularis was present. They found arthrosis that was mild in 19 patients and moderate in 1 patient. The mean rates of subscapularis atrophy and residual glenoid defects were 6% and 4%, respectively, according to the abstract.
