Brachial plexus injury (BPI) is one of the most devastating injuries from the point of view of the patient. The Saha procedure was commonly used for a reconstructive option for shoulder abduction, and the Steindler procedure for a reconstructive option for elbow flexion in case of brachial plexus injury.We report a teenager male presented with inability to move his right shoulder and elbow after a motor vehicle accident 5 weeks before. He was unable to move the elbow and shoulder, but the hand and wrist still had a good function. From the right shoulder X-Ray there is proximal humerus fracture. Steindler flexorplasty was performed after 3 months strengthening program. 6 months after Steindler flexorplasty, Saha’s procedure was performed to improve the shoulder movement. The shoulder can abduction 20⁰-55⁰ and the elbow can flex 20⁰-80⁰ after the surgery.In this case, the superior trunk of the brachial plexus was injured due to the shoulder and the neck forcibly widens after direct shoulder trauma. Saha’s procedure after Steindler flexorplasty is best for superior trunk brachial plexus injury, a simple procedure with minimal blood loss, which provided functional improvement.Steindler flexorplasty and Saha’s Procedure are two procedures very beneficial to the patients who experienced superior trunk brachial plexus injury.
