If the patient has presented very late, then it can lead to radial nerve palsy with atrophy of the muscles of the back of the forearm. He or she would have permanent wrist, finger, and thumb drops.
Such condition of wrist drop and finger, thumb drop (inability to extend the wrist, thumb, and fingers) is also usually seen in long-standing compression of the radial nerves due to tumors or injuries of the radial nerve after accidents or fractures.
How are late cases of radial nerve compression managed?
Release of the compression along with the tendon transfers should be done to strengthen the weak portions of the hand.
A strong tendon of the hand is re-routed to substitute a weaker or lost movement of the hand.
How is tendon transfer done for radial nerve compression?
During tendon transfers for radial nerve palsy, 3 tendons from the front of the forearm and hand are taken, re-routed, and sutured to the tendons of the back of the forearm and hand so that the patient can extend his wrist, fingers, and thumb.
- The surgery is usually done under brachial block or general anesthesia and a splint or slab is given for immobilization in the post-operative period.
- The patient is usually discharged on the second day after the surgery.
- Sutures are removed 14 days after surgery.
- Splint is removed 3 to 4 weeks after the surgery and gradual training of the transferred muscles or tendons is started so that they regain their newly assigned function.
