Total epiphyseal separation of distal humerus

Total epiphyseal separation of the distal humerus is a rare epiphyseal injury of the elbow joint in children. The epiphyseal separation of the epiphyseal center of the epiphysis has not occurred completely before it is easily confused with the humeral epicondylar fracture and dislocation of the elbow joint. The total epiphyseal separation after the ossification center appears is easily misdiagnosed as a transcendental fracture. The epiphysis of the distal humerus is composed of the humerus epicondyle, the pulley, the medial epicondyle, and the lateral epicondyle condyle. The humerus epiphysis and humerus pulley epiphysis are connected by cartilage, so this part is weak. Generally, violence can cause the humeral epicondylar cartilage to break, resulting in a fracture of the humeral condyle. But sometimes external forces can separate the entire epiphysis of the distal humerus. The two are not exactly the same in treatment. The former often requires surgical open reduction, and the total osteophyseal separation can be reduced by closed methods. This kind of injury is easy to be misdiagnosed and missed. If improperly treated, it can cause severe elbow deformity of the elbow joint and affect function.
