Missed Bilateral Anterior Shoulder Dislocation With Bilateral Coracoid Fracture and Unilateral Long Head of Biceps...

Missed or chronic bilateral anterior shoulder dislocation is a rare presentation, usually secondary to epileptic attack. We present herein an exceptional case of this injury pattern, associated with bilateral displaced fracture of the coracoid process, and unilateral rupture of the long head of biceps. Treatment consisted of open reduction through osteotomy of the lesser tuberosity, with additional stabilization of the glenohumeral joint, using the Latarjet procedure by transposition of the coracoid fragment with its attached conjoint tendon to the antero-inferior glenoid rim. Rupture of the long head of the biceps required tenodesis. Temporary glenohumeral pin transfixation was performed for residual instability at the end of the procedure. Patients with postictal shoulder pain, discomfort, or disability should be investigated with adequate radiographs, in addition to CT scan or MRI when needed. Early diagnosis allows for safe closed reduction, and helps avoid late and more complex surgical treatment required for missed or chronic dislocations.
