RESUMO
OBJECTIVE: To evaluate the functional and radiographic results in patients undergoing shoulder anterior soft tissue stretching in association with open reduction and internal rotation osteotomy to centralize the humeral head as a treatment for Erb-Duchenne obstetric palsy sequelae. METHOD: A total of 35 patients underwent this surgical treatment, and the mean follow-up was 4.6 years. The Mallet scale was applied before and after the surgical procedure. A total of 20 patients underwent computed tomography to assess the glenoid version and humeral head subluxation. RESULTS: Functional improvement was achieved, as evidenced by an increase in the Mallet scale score from 12.14 to 16.46 (p<0.001). The correction of retroversion was achieved once the glenoid version ranged from -21.4 to -12 degrees (p<0.001). The humeral head subluxation improved from 6.5 to 35.2% (p<0.001). Patients older than 6 years of age did not achieve glenohumeral joint improvement with respect to dysplastic abnormalities. CONCLUSION: Internal rotation osteotomy in association with the stretching of anterior soft tissues of the shoulder in patients under the age of 7 years provided improvements in the function, retroversion, and subluxation of the glenohumeral joint.
