Case:
We report a rare case of a spontaneous, atraumatic rupture of the anterior and middle heads of the deltoid with an underlying massive rotator cuff tear. Unique clinical findings included a palpable mass of torn deltoid distally with a proximal tissue defect. Magnetic resonance imaging of the deltoid demonstrated complete tear of the anterior head; involvement of the middle head was found intraoperatively. Given the acute nature of injury and potential impact on the feasibility of future reverse shoulder arthroplasty, surgical repair of the torn deltoid was discussed with the patient and performed via superior approach.
Conclusion:
Direct surgical repair is a viable treatment option if diagnosed early.
