Which of the following features should make you consider a rotator cuff injury rather than an axillary nerve lesion?

Patients with rotator cuff injuries often present with limited shoulder abduction but normal forward flexion of the elbow. This is because the humerus subluxates upwards when the rotator cuff is ruptured, and the coracoid bone prevents full abduction. Additionally, the long head of the biceps may be ruptured, causing the biceps to bunch up during elbow flexion. On attempted abduction, the shoulder may elevate, giving it a characteristic shrugging appearance. The range of passive movement of the shoulder is also limited and sometimes painful.
