Elbow dislocation is the most common joint dislocation in childrens, second most common in adults. It is often observed in young adults. Posterior elbow dislocation develops in 90% of the cases during axial loading while elbow is in valgus and supination. Depending on the severity of the injury, simple elbow dislocation containing capsuloligamentous lesion or complex elbow dislocation accompanied by radial head dislocation and coronoid fractures (terrible triad) may develop. The case is important since the trauma is located in the elbow joint hosts a large surface and due to the function of the surrounding ligaments close to the neurovascular structures. Diagnosis and treatment of elbow trauma is complex, and complications may occur: neurological complications in the early stages, including vascular injury and compartment syndrome. Late-term complications are motion loss, post-traumatic arthritis, myositis ossificans and heterotopic ossification, instability, radioulnar sinositoz/instability, cubitus recurvatum, nonunion, bone healing disorders/malunion infection and wound problems.
