Background: External Rotational Humeral osteotomy is used to address the external rotation deficit in older children with obstetric brachial plexus Injury (OBPI). Although this procedure improves the cosmetic effect of shoulder subluxation, it has no effect on the underlying structural (glenohumeral deformity and scapular elevation and rotation) and functional problems. In this study, improvements in glenohumeral joint alignment; scapular hypoplasia, elevation, and rotation (SHEAR) deformity; and upper extremity functional movements were demonstrated in adult patients with OBPI 1 year after the mod Quad and/or triangle tilt surgeries. Methods and Patients: The outcome of humeral rotational osteotomy reported in the literature was compared with the results from 43 adult patients with OBPI (21 men and 22 women; 23 right and 20 left sides) with a mean age of 21.3 years (range, 17 to 38 years) who underwent mod Quad and/or triangle tilt surgeries and had over 12 months of postoperative follow-up (mean 22.9 months; range, 12 to 50 months). Results: The preoperative average modified total Mallet score, including supination, was 14.6 ± 3.5 (P < 0.0001) in the 43 adult patients with OBPI in this report. This total Mallet score was significantly improved to 22 ± 3.9 (P < 0.0001) over 12 months after mod Quad and/or triangle tilt surgeries. Thirty-two (75%) of the patients showed great improvement in all upper extremity functions: shoulder abduction, external rotation, hand-to-mouth, hand-to-neck, hand-to-spine, and supination. The improvement after humeral osteotomy reported in the literature was a cosmetic effect that did not address the underlying structural and functional problems and was found to decrease the improved shoulder abduction in long-term follow-up. Conclusions: Thirty-two (75%) of 43 adult patients with OBPI showed great improvement in all upper extremity functions 1 year after mod Quad and/or triangle tilt surgeries. The other 11 patients (25%) showed improvement in hand-to-mouth movement and/or supination. In contrast, humeral osteotomy, as reported in the literature, improved the cosmetic effect of shoulder subluxation but had no effect on the underlying structural and functional problems.
