Summary

The aim of the study is to evaluate the results of reconstruction of neglected and failed cases of terrible triad of the elbow

Detailed description

A terrible triad injury consists of posterior dislocation of the elbow associated with a radial head fracture and a coronoid fracture. This injury occurs during a fall onto an outstretched arm, and it presents a disruption of the bony and capsuloligamentous structures from the lateral side, which progresses anteriorly and medially.The primary goal of surgical treatment for terrible triad injury is to restore elbow function with. good stability. The current standard treatment involves internal fixation and reconstruction of the bony and ligamentous structures to allow early mobilization. Fixation or replacement of radial head fractures and lateral ligament reconstruction represent the main operative procedures. A biomechanical and clinical study showed that restoration of the coronoid process and anterior capsule is an important step for a stable elbow. old "terrible triad" of elbow with no operative history is difficult to treat. The elbow's functions and stabilization can be recovered by thorough elbow release, repair of coronoid process and anterior capsule, radial head fixation or replacment reconstruction or repaire of, lateral collateral ligament and reinsertion of the common extensor tendon, combined with hinged external fixator Although improved knowledge of this injury has yielded favourable clinical outcomes, complications continue to occur, including stiffness, recurrent subluxation or dislocation, heterotopic ossification, ulnar nerve neuropathy, and arthritis.The common causes of revision after terrible triad injury reconstruction are stiffness and recurrent instability, Stiffness and instability, among all these complications, are indeed the most recurring. A stiff or unstable elbow is very poorly tolerated because of the lack of compensatory motion in adjacent joints, So it's very important to detect causes and risk factors that leading to fail terrible triad reconstruction.
