The modeling of elbow posterior instability after injuries of forearm anterior structures (experimental study)

Authors made experiment to study conditions at which recurrent posterior dislocation of forearm bones occurs. Bone and soft tissue structures providing stability of elbow joint, necessary and sufficient conditions of its stabilization were studied. It is found out that the most important structure stabilizing an elbow joint is the forward portion of medial collateral ligament. Its damage against the background of bone fracture results in posterior dislocation. The biomechanical substantiation of efficiency of various techniques of operative treatment of old recurrent posterior dislocation of forearm bones is received.
