Abstract
Rotation osteotomy of the humerus has been described by several authors to treat the internal rotation contracture of the shoulder in Erb palsy. The main aim of the osteotomy in Erb patients is to bring the functioning hand to the face which greatly improves function. The author has performed the rotation humeral osteotomy in children with total obstetric brachial plexus palsy aiming for the improvement of the cosmetic appearance of the limb rather than improvement function. This article specifically reports on this group of patients.Over the last 15 years, the author has performed rotation humeral osteotomy in 13 children (mean age 6 years; range, 4.5-9 years) with total obstetric brachial plexus palsy aiming for improvement of the cosmetic appearance of the limb rather than improvement of function. All children had a triad of severe internal rotation contracture of the shoulder, severe flexion contracture of the elbow, and poor hand function.After a mean follow-up of 2 years following the humeral osteotomy, all patients/parents were satisfied with the result and a panel of plastic surgeons confirmed the significant improvement in aesthetics. Reasons for this improvement following the osteotomy were as follows: the child no longer needed to stand with shoulder slightly abducted, the antecubital fossa became visible in the standing position, and the forearm no longer appeared excessively pronated. Of more importance, was the improvement in elbow flexion contracture which had major contribution in improving limb appearance and the perception of length discrepancy between the affected and the contralateral normal limb.The humeral osteotomy improves the cosmetic appearance of children with total palsy and the triad of severe internal rotation contracture of the shoulder, severe flexion contracture of the elbow and poor hand function.
