Management of residual internal rotation deformity in obstetric brachial plexus palsy: A case report
Author(s): R Hariharasudhan, Sunil Kumar PC and Manjunath M
Abstract: Background; Obstetric brachial plexus palsy (OBPP) often leads to residual internal rotation contracture of the shoulder with progressive glenohumeral deformity due to muscle imbalance. Surgical release and external rotation osteotomy can improve function in affected children.
Case Presentation: A 5-year-old boy presented with right shoulder deformity and difficulty in hand-to-mouth movement following birth-related Erb-Duchenne’s palsy. Examination showed 55° fixed internal rotation, absent external rotation, 10° elbow flexion contracture, and Modified Mallet Grade II-III function. Imaging revealed dysplastic humeral head, absent glenoid concavity, and scapular elevation. He underwent contracture release and 40° proximal humeral external rotation osteotomy followed by immobilization and rehabilitation.
Results: At six months, deformity was corrected, hand-to-mouth function restored, and active external rotation improved to 50°. Modified Mallet grade improved to IV, with minimal residual weakness.
Conclusion: Combined contracture release and humeral osteotomy significantly improved shoulder function and deformity in OBPP. Early intervention and rehabilitation are essential for optimal outcomes.
