RT Journal A1 BOWERS, RALPH F. T1 COMPLETE ACROMIOCLAVICULAR SEPARATION Diagnosis and Operative Treatment JF The Journal of Bone & Joint Surgery JO The Journal of Bone & Joint Surgery YR 1935 FD October 1 VO 17 IS 4 SP 1005 OP 1010 DO UL http://dx.doi.org/ AB Complete acromioclavicular separation is a relatively minor injury which is often the cause of disability when not correctly diagnosed and treated. If the x-rays are negative for fracture of the outer end of the clavicle and dislocation of the head of the humerus, the diagnosis of this injury may be established by the recognition of the typical deformity which is corrected by raising the arm upward.Treatment should be undertaken without delay and should consist of an open operation with approximation of the articular surfaces of the joint and reconstruction of the torn ligaments.
