Percutaneous skeletal fixation of a humeral epicondylar fracture, whether medial or lateral, is a minimally invasive surgical procedure aimed at stabilizing fractures located at the distal end of the humerus. The epicondyles are bony protrusions on the humerus that serve as attachment points for muscles and ligaments. Fractures of these areas are classified as extra-articular, meaning they do not extend into the joint space, and can significantly impact the function of the elbow and forearm. The procedure begins with a thorough assessment, including obtaining separate radiographs to confirm the presence and extent of the fracture. A neurovascular examination is also conducted to ensure that the surrounding nerves and blood vessels are intact, which is crucial for preventing complications. Once the fracture is confirmed, the fragments are manually manipulated back into their proper anatomical positions. This manipulation is critical for ensuring optimal healing and function post-surgery. The ulnar nerve, which runs close to the medial epicondyle, is carefully located and protected during the procedure, sometimes necessitating a small incision to facilitate this. Following the reduction of the fracture, percutaneous pins or K-wires are inserted to provide stability to the fracture fragments. The use of these fixation devices allows for a less invasive approach, reducing recovery time and minimizing soft tissue damage. The procedure concludes with the application of a long arm cast to immobilize the area and support the healing process.
