CPT® Code 25315

The procedure described by CPT® Code 25315, known as the flexor origin slide, is a surgical intervention aimed at addressing flexion contractures of the wrist, hand, and fingers. These contractures can arise from conditions such as cerebral palsy or ischemic injuries, which may lead to a condition known as Volkmann's contracture. In simpler terms, this procedure is designed to relieve tightness and restore function in the affected areas by allowing the muscles and tendons to slide more freely along the forearm. The surgical approach involves making an incision along the ulnar side of the forearm, which provides access to critical structures such as the ulnar and median nerves, as well as the brachial artery. During the operation, these nerves are carefully identified and protected to prevent damage. The procedure includes decompressing the ulnar nerve and releasing specific muscles from their bony attachments, which facilitates their distal movement. This sliding action of the muscles is essential for alleviating the contractures, ultimately improving the range of motion and functionality of the wrist and hand. After the surgical site is closed, the wrist and hand are immobilized in an extended position to promote healing and ensure the best possible outcome for the patient.
