An open treatment of a humeral epicondylar fracture involves a surgical procedure aimed at correcting a fracture located at the medial or lateral epicondyle of the distal humerus. The epicondyles are bony projections at the lower end of the humerus, which serve as attachment points for muscles and ligaments. This type of fracture is classified as extra-articular, meaning it does not extend into the joint space, and specifically affects the medial or lateral columns of the distal humerus. The procedure is indicated for cases where there is an isolated displaced fracture of either the medial or lateral epicondyle, but not both simultaneously. During the surgery, the fracture site is carefully exposed to allow for direct visualization and access. The ulnar nerve, which runs close to the medial epicondyle, is identified and protected to prevent nerve damage during the procedure. After clearing any debris from the fracture site, the fracture is reduced, meaning the bone fragments are realigned to their normal position. For stabilization, smaller fragments may be secured using sutures, while larger fragments may require internal fixation methods such as K-wires, pins, nails, or screws. Once the fracture is adequately stabilized, the surgical wound is closed, and a splint is applied to support the arm during the initial healing phase.
