Outcomes of Woodward's Procedure for Sprengel's Shoulder Using Neurophysiological Monitoring of the Brachial Plexus Without Clavicular Osteotomy: A Retrospective Study.

Introduction For Sprengel deformity, a variety of operations are available, with Woodward's procedure being a favorable option with good outcomes. This study aims to assess the outcomes of Woodward's procedure with brachial plexus monitoring to prevent the possible complications of nerve injury and consequent deficits. Methods In our study, we included 18 patients with Sprengel deformity treated with Woodward's procedure using intraoperative neuromonitoring for the brachial plexus from 2013 to 2019 at our institute. For each patient, we collected information about age, gender, follow-up duration, affected shoulder side, and presence of an omovertebral bar. Also, preoperative and postoperative degrees of shoulder abduction, Cavendish grade of cosmetic appearance, Rigaults grade, and difference in scapular elevation along with postoperative complications were all measured to evaluate the outcomes. Results The mean duration of follow-up was 12 months. The average preoperative Cavendish grade was 3.1, which decreased to 1.3 on the final follow-up. The average preoperative Rigault grade was 2.5, which has decreased to an average of 1.8. The average increase in the degree of shoulder abduction postoperatively was 48.3°. The average preoperative difference in scapular height (mm) was 26.9, which decreased to an average of 12.2. Furthermore, the final outcome was not impacted by the absence or the existence of the omovertebral bar. Conclusion Woodward's procedure using intraoperative neuromonitoring without clavicle osteotomy for Sprengel's deformity successfully corrects the deformity and decreases the risk of iatrogenic brachial plexus injury.
