Case ReportDisplaced acromion fracture: A rare injury, case report

- There is no widely accepted treatment algorithm and fixation method of acromion fractures.
- In improperly treated acromion fractures, pain, movement restriction, subacromial impingement, rotator cuff injury and symptomatic nonunion can occur.
- Symptomatic nonunion, subacromial impingement, displacement more than 1 cm, open fractures and disruption of superior shoulder suspensory shoulder complex require surgical treatment.
- Compression with a good reduction and cannulated screw can make the fracture healing complete successfully.

IntroductionAcromion fractures are extremely rare. There are no common accepted treatment schemes and fixation methods We aimed to present a case which may contribute to the diagnosis and treatment of acromion fracture in a patient with polytrauma.Presentation of caseAcromion fracture associated with scapula and clavicle fractures was diagnosed in 40 years old patient and treated with open reduction and cannulated screw fixation. The fracture healing was completed without causing subacromial impingement.DiscussionIn patients with polytrauma, diagnosis and treatment of acromion fractures can be delayed or overlooked. In improperly treated acromion fractures; pain, movement restriction, subacromial impingement, rotator cuff injury and symptomatic nonunion can occur.ConclusionWe recommend early surgical treatment for displaced acromion fractures, reduction of subacromial space and disruption of the superior shoulder suspensory complex.
