Stemless reverse total shoulder
These authors, including the co-conceptor of the design, enrolled 101 patients having 105 stemless reverse total shoulders in a prospective study, with a minimum follow-up period of 24 months. 91 procedures in 87 patients (61 men and 26 women), with a mean age of 73 years, were available at a mean follow-up of 41 months (range, 24-69 months).
Ninety-six percent of patients rated their satisfaction as good or excellent. Mean flexion was 143° (range, 90°-170°), and mean external rotation was 39° (range, 20°-70°). The Constant score improved from 40 points preoperatively to 68 points at last follow-up (P < .001). The mean American Shoulder and Elbow Surgeons score was 24 points. The mean neck-shaft angle was 154° (range, 142°-165°). Inferior scapular notching occurred in 17 cases (19%). The notching rate was higher when the glenometaphyseal angle increased (P < .001), when the inferior tilt decreased (P = .003), and when the neck-shaft angle increased. The authors reported no evidence of component loosening.
