ABSTRACT: Humeral derotational osteotomy is currently considered the definitive treatment for sequelae of POPB involving a fixed internal rotation deformity of the shoulder. Its purpose is to position the arm in a more functional orientation, thereby improving patients’ quality of life. This study aimed to evaluate the effects of this procedure on shoulder function. Methods: Thirteen patients underwent humeral derotational osteotomy at the Order of Malta Hospital in Dakar between January 2016 and December 2024. The humeral osteotomy was performed via an anterolateral approach just below the insertion of the deltoid muscle and fixed using stainless steel plates and screws. The mean age of the patients at the time of surgery was 9.23 years. Functional outcomes were assessed using the modified Mallet score. Results: At a mean follow-up of 43.54 months, improvements were noted in external rotation, with the mean Mallet score increasing from 2 to 3.38, and in abduction, with the mean score rising from 2.85 to 3.31. Complications occurred in three (3) patients, including hardware loosening and radial nerve injury. Conclusion: Humeral derotational osteotomy is a valuable treatment option for managing the sequelae of congenital brachial plexus palsy in patients with internal rotation contracture of the shoulder and advanced glenohumeral dysplasia, which contraindicates soft tissue release and tendon transfers
