Flexor to Extensor Tendon Transfers in the HandFrom the Peripheral Nerve Injuries Unit, Royal National Orthopaedic Hospital Trust, Stanmore, London, UK Correspondence: Mr R. Birch, MChir, FRCS, Royal National Orthopaedic Hospital Trust, Brockley Hill, Stanmore, Middlesex HA7 4LP, UK. We reviewed 49 cases of flexor to extensor tendon transfer following injury to the radial nerve (22) or brachial plexus (27). Post-operative follow-up averaged 5.6 years (0.5–12.5). Function was improved in 84% (41) of patients. 16% (8) reported no improvement; of these, four (50%) had associated vascular injuries. In those with improvement, impaired coordination and dexterity were reported by 79% (15 of 19) of the plexus injuries and in 64% (14 of 22) of the radial nerve palsies. Premature fatigue was noted by 89% (17 of 19) of plexus injuries and in 82% (18 of 22) of radial nerve palsies. The power of wrist extension averaged 22% of the contralateral side (8% to 80%), power of digital extension was 31% (5% to 130%), and power grip was reduced to 40% (5% to 86%).
