title: Silastic interposition arthroplasty of the shoulder.
abstract: We report a series of 12 Silastic interposition arthroplasties of the shoulder. There was a very high incidence of dislocation or fragmentation (50%) leading to early failure of the device in seven patients. Our analysis suggests that the operation should be restricted to rheumatoid arthritic shoulders in which there is no loss of bone or distortion of the humeral head.
