Subacute Acromioclavicular Dislocation After Basal Coracoid Process Fracture: Indirect Reduction without Open Reduction and Internal Fixation

A 55-year-old man presented with an isolated undisplaced basal coracoid process (CP) fracture after direct trauma over his right shoulder. One week later, he presented with pain and anatomical deformity over the acromioclavicular joint (ACJ). Shoulder x-rays and computerized tomography revealed a complete acromioclavicular (AC) dislocation and displaced CP fracture. Anatomical AC reduction and ipsilateral coracoid fracture reduction were obtained using fixation with a hook plate. At 12-month follow-up, the patient regained functionality and showed complete CP consolidation and anatomic alignment of the ACJ.Our alternative treatment of coracoid fracture associated with secondary subacute AC dislocation showed satisfactory functional results.
