A tendon transfer surgery can be performed to treat irreversible and longstanding radial nerve palsy in order to improve the lost hand function. Case report: A 39-year-old right-handed female offce worker presented with deformity in her left arm and drop hand. She had a motorcycle accident a year before and was treated by a traditional bonesetter. The extension movements in her left wrist and fngers were restricted. We performed an ORIF with bone graft at her left nonunion humerus and also tendon transfer procedure to treat the high radial nerve palsy. We use the modifed Jones procedure to attach the palmaris longus to the extensor pollicis longus. After that, we attached the fexor carpi radialis to extensor digitorum communis and extensor carpi radialis brevis with the Pulvertaft technique. After fve months of follow up, the patient fnally can extend her wrist and thumb. Conclusion: Modifed Jones procedure is a viable option to treat high radial nerve palsy with great functional outcomes after 5 months of follow up. Introduction Fractures of the humeral shaft contribute to 1–3 % of musculoskeletal fractures. The fracture is usually caused by a low-energy injury mechanism. Meta-analysis of 21 studies showed that the incidence of radial nerve palsies caused by humeral shaft fractures is 1.18 % (532/4517), with middle to distal humerus as the most common site [1]. Permanent nerve dysfunctions can be treated by reconstructive surgeries i.e. tendon transfers, especially for longstanding radial nerve palsy in order to improve the lost hand function. Tendon transfer surgery can be called successful if it can restore pre-injury functions of the wrist and fngers without any signifcant motor defcit on the hand [2]. Case report A 39-year-old female came to our clinic with a deformity in her left arm and drop hand after previous road traffc injury.
