There are few reports in literature dealing with spontaneous rupture of the deltoid muscle. In the reported cases, the injury occurred in patients with chronic, massive rotator cuff tears and was in some instances responsible for an acute onset of shoulder weakness. One of the possible causative factors claimed to explain rupture or detachment of the deltoid muscle is a history of repeated steroid injections for frozen shoulder and longstanding rotator cuff tears (Allen and Drakos 2002). Because, in patients with deltoid rupture and massive rotator cuff tear, contraction of the intact deltoid can lead... 

Among the degenerative arthropathies that typically involve the shoulder, there are a variety of conditions related to crystal deposition diseases, including renal osteodystrophy, milk alkali syndrome, hyper-vitaminosis D and the so-called Milwaukee shoulder syndrome . This last condition, which is also known as apatite-associated destructive arthritis, hemorrhagic shoulder or rapid destructive arthritis of the shoulder, consists of massive rotator cuff tear, osteoarthritic changes, hlood-stained noninflammatory joint effusion containing calcium hydroxyapatite and calcium pyrophosphate dihydrate crystals, synovial hyperplasia and extensive destruction...

Reverse prosthesis designs were developed for use in cases of rotator cuff tear arthropathy, and although they continue to be used primarily in such cases, they have also been used in others. From a series of 240 reverse prosthesis cases. Wall and colleagues [39] report that 31% were used for rotator cuff tear arthropathy, 22.5% for revision arthroplasty, 17% for massive rotator cuff tears, 14% for primary OA, and 14% for posttraumatic arthritis. In marked contrast to other TSA studies, only 1 of the 240 cases reported by Wall and coworkers was done for RA [39].
