CPT® Code 24330

Flexor-plasty of the elbow, as described by CPT® Code 24330, is a surgical procedure aimed at repairing the flexor-pronator complex, which may be partially or completely detached at the elbow joint. This procedure is particularly indicated for patients who have experienced significant loss of function due to injuries or conditions affecting the flexor muscles, which are crucial for elbow flexion and forearm pronation. The surgery involves making an incision over the elbow joint to access the underlying structures. During the procedure, the ulnar nerve is carefully dissected and protected to prevent nerve damage. If the flexor-pronator complex remains intact, it is surgically detached along with a segment of the medial epicondyle using a chisel. The flexor group is then meticulously dissected, and a planned attachment site on the humerus is prepared by drilling a hole. The flexor group is subsequently transferred proximally by 2 to 6 centimeters and reattached to the medial or mediovolar surface of the humerus. To secure the flexor group in place, a fixing wire is pulled through the drilled hole, and additional screw fixation may be employed to stabilize the epicondyle fragment. This procedure is essential for restoring elbow function and improving the patient's ability to perform daily activities that require flexion of the elbow.
