Surgical Treatment of Severe Sprengel's Deformity

An adolescent girl who presented with obviously impaired shoulder abduction due to untreated severe Sprengel's deformity underwent deformity correction surgery. Intraoperative neuromonitoring was used to warn of potential brachial plexus injury during a modified Woodward procedure. At 3-month follow-up, range of shoulder abduction had improved significantly.Sprengel's deformity is a rare congenital shoulder deformity, and the Woodward procedure could cause nerve injury in patients with severe Sprengel's deformity. Neuromonitoring can be performed intraoperatively to avoid brachial plexus injury.
