Massive irreparable rotator cuff tear and associated deltoid tear. Does the reverse shoulder arthroplasty and deltoid repair be a possible option of treatment?

RSA associated with a repair of deltoid tear could be a viable surgical option in cases of tear involving the anterior and middle deltoid associated with a RCA. Patient with a preoperative chronic axillary nerve neuropathy associated with a deltoid muscle tear should be cautioned about the possibility of lower functional outcomes.
