Percutaneous skeletal fixation of a supracondylar or transcondylar humeral fracture, with or without intercondylar extension, is a minimally invasive surgical procedure aimed at stabilizing specific types of fractures in the distal humerus. The distal humerus features two prominent bony projections known as the lateral and medial epicondyles. A supracondylar fracture occurs just above these epicondyles, while a transcondylar fracture extends through them, potentially involving the intercondylar region, which includes critical structures such as the trochlea and olecranon fossa. This procedure is indicated when these fractures occur, as they can significantly impact the function of the elbow and arm. Prior to the fixation, imaging studies, such as radiographs, are performed to confirm the presence and extent of the fracture. The procedure involves the manual reduction of the fracture fragments, ensuring they are realigned to their normal anatomical position. The ulnar nerve, which runs close to the fracture site, is carefully located and protected during the procedure, sometimes necessitating a small incision to facilitate this. The stabilization of the fracture is achieved through the insertion of percutaneous pins or K-wires, which are strategically placed to maintain the alignment of the bone fragments. The use of imaging is critical throughout the procedure to verify both the reduction of the fracture and the correct positioning of the pins. Finally, a long arm cast is applied to provide additional support and immobilization during the healing process.
