Surgical management of isolated acromion fractures: technical tricks and clinical experience
- View All
SUMMARY: Acromion fractures of the scapula are rare and most often occur with concomitant fractures of the ipsilateral glenoid, neck and body of the scapula as sequelae of high-energy injuries. Indications for operative management include symptomatic nonunion, displaced fractures, or acromion fractures associated with other lesions of the superior shoulder suspensory complex. Less displaced acromion fractures resulting in decreased subacromial space may also warrant surgery. Although surgical indications have been reported, the literature regarding surgical approaches and fixation techniques for management of these factures is limited. Acromion fractures can generally be addressed with a direct posterior approach using either tension band or low-profile plating in combination with cortical lag screws to obtain a stable construct. This technique is both effective in achieving fracture union and safe to the patient. When associated with a more complex fracture of the glenoid and/or scapula body, the surgical approach and fixation strategy should be dictated by the optimal approach to other displaced elements of a scapula fracture. The purpose of this study was to describe a step-wise approach to the surgical management of isolated acromion fractures, describe surgical tips and techniques, and to present the early clinical outcomes in 13 patients after surgical treatment with this approach.
