Abstract

Background
Injury of the radial nerve in the arm is a common site for injury especially with bone trauma. This type of injury can be managed by nerve transfer to the extensors of the fingers and the wrist and this is superior to using grafting or transfer of the tendons. Injury of the radial nerve causes weakness of the fingers and wrist extension. Distal transfer of functioning nerves to the radial nerve branches can restore independent function which is not the case in transferring tendons and it also overcomes the obstacle of long distance of the repair for better recovery.

Aim: The purpose of the study is the assessment of the results of nerve transfers where the branch of flexor digitorum superficialis is transferred to the branch of extensor carpi radialis brevis for restoration of extension of the wrist, and the flexor carpi radialis branch of the median nerve is destined to be transferred to the posterior interosseous nerve to restore extension of the thumb and fingers.
Patients:Ten patients were included in the study suffering from radial nerve injury and they were followed up for 1 year and results were collected and presented in our prospective study and outcome was assessed using MRC scale where seven of our patients improved to grade 4 on the scale
Conclusion:
We concluded that using branches of the median nerve to be transferred to the branches of the radial nerve in patients with radial nerve palsy is an effective surgical option with good outcome.
