A massive rotator cuff tear in association with acute traumatic posterior
glenohumeral dislocation is rare. To our knowledge, only four documented cases
have been reported in the literature. We present two additional cases of such
injury secondary to the traffic accident. The first patient had an unsuccessful
closed reduction due to the posterior instability while the second developed the
profound shoulder weakness following the reduction.
From the findings of our
cases together with the previous reports, every patient had a unique injury
mechanism of high-energy directed axial loading on an outstretched, adducted, and
internally rotated arm. The glenohumeral capsule and rotator cuff were uniformly
avulsed from the humeral attachment, and the supraspinatus and infraspinatus were always involved. However, the clinical presentations were variable based on the
severity of the associated rotator cuff tear. The outcomes of operative treatment
in this type of injury with the open repair were favorable.
