Surgical technique for treating unstable os acromiale in athletes

Rationale. Os acromiale is a variant of nonunion of the apophysis of the acromial process, occurring in 6–8% of cases in the adult population. Symptomatic os acromiale may be accompanied by pain and decreased muscle strength during active sports. Target. The main goal is to develop an effective method for of treatment of symptomatic os acromiale in athletes. Materials and methods. A technique for surgical treatment of unstable os acromiale in athletes has been proposed, including mobilization of a free bone fragment of the acromion, formation of bone tunnels using a double-barreled guide for parallel drilling of bone canals and osteosynthesis using two cannulated screws. Conclusion. Thus, our proposed technique allows us to achieve reliable fixation of an unstable fragment of the acromial process without the use of additional grafts with simultaneous correction of the shape of the acromial process of the scapula to prevent the subsequent development of impingement syndrome and disruption of the congruence of the acromioclavicular joint.
