Displaced acromion fracture associated with anterior glenohumeral subluxation in a polytrauma patient: a case report
Abstract Background: Fractures of the acromion process of the scapula are a rare entity that account for approximately 7% to 16% of all scapula fractures, which in turn account for 0.5% to 1% of all fractures in the body. These fractures usually occur from direct trauma to the shoulder or as a result of overuse injuries to the shoulder joint. Given the rare incidence of these fractures, there are currently no treatment guidelines for treating these fractures when diagnosed. Case presentation: In this case report, we discuss how a secondarily diagnosed displaced acromion fracture associated with anterior glenohumeral joint subluxation in a polytrauma patient was surgically treated. After surgical fixation of this fracture and accordingly neutralizing all the dislocating tension forces exerted by the deltoid muscle, the glenohumeral joint was spontaneously relocated postoperatively. Conclusion: Patient with shoulder trauma should be carefully examined for acromion fractures. Acromion fractures can be treated with good results with early surgical treatment and proper fixation. Surgical treatment is important to regain shoulder functions, as it enables early rehabilitation.
