Adhesive capsulitis, also referred to as frozen shoulder, refers to an insidious syndrome of shoulder pain and restricted movement in the absence of shoulder impingement and rotator cuff injury. The patient generally complains of loss of the normal... 

Transverse fractures result from direct blows. Twisting injuries produce the more common spiral fracture. In infants, this injury should always rouse suspicion of child abuse. The position of the bony fragments will be determined by the pull of adjacent muscles. For proximal metaphyseal fractures, the rotator cuff abducts the proximal fragment while the distal fragment is adducted by the pectoralis muscle.

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...
