Background: The radial nerve is the largest terminal branch of the brachial plexus. Loss of radial nerve function creates a significant disability in the hand. The grip is severely impaired following loss of radial nerve function as a result of loss of extension of wrist, metacarpophalangeal joints of fingers and interphalangeal joints of the thumb.
Methods: Prospective, quasi experimental study carried out for 3 years at National Institute of Traumatology and Orthopaedic Rehabilitation (NITOR). Forty-eight patients of high radial nerve palsy were selected for tendon transfer (split FCU tendon to EDC and EPL) and PT transferred to ECRB.
Results: Mean age of the patients was 28.92 years (range 15-45 years), significantly higher in 26-35 years age group. There was preponderance of injury to the dominant right side (58.33%) than the none-dominant left side (41.67%). Motor vehicle accident (66.67%) was the common cause of injury followed by assault (33.33%). Out of 48 patients, 28 patients score 8-9 (excellent), 16 patients score 7 (good), 4 patients scores 5 (fair). So that, total 44 patients achieved satisfactory outcome (91.67%) and 4 patients achieved unsatisfactory outcome (8.33%). All patients can extend their wrist, fingers and thumb. Beyond this, all patients can flex their fingers up to mid palmar crease and thumb can be extended separately-independent of EDC function.
Conclusions: Transfer of split FCU tendon to EDC and EPL for fingers and thumb extension in irreparable and neglected long standing high radial nerve palsy results significant functional outcome.
