Isolated Traumatic Tear of the Middle Head of the Deltoid Muscle: A Case Report.

CASE

A 27-year-old male pedestrian struck presented with left shoulder pain and weakness 4 months postinjury, with an isolated middle head of the deltoid tear. The patient's pain persisted despite extensive nonoperative management. The deltoid was primarily repaired to the lateral acromion using a transosseous suture repair technique.

CONCLUSION

Suture repair of the deltoid to the acromion using transosseous tunnel fixation is a successful treatment for traumatic, isolated tears of the middle head of the deltoid muscle that fail conservative treatment. After surgical repair and physical therapy, our patient recovered full, pain-free range of motion and strength at 6 months.
