Interposition in the median and ulnar nerve; a 40 year follow-up. (P2.019)

TL;DRAbstract

Objective To describe a unique observation of nerve interpositions in the ulnar and median nerve, with a 40-year follow-up. Background Irreversible peripheral nerve damage is often treated with surgery. Nerve interposition is usually performed with auto grafts. Design/methods Case report, based on history, clinical details, NCV/EMG and imaging by nerve ultrasound and MRI. Case report A 60-year old patient had a complete lesion of the median and ulnar nerve following a plaster cast at the age of 10. The hand was severely impaired. Sural nerve grafts interpositions were implanted and with continuous training a substantial functionality of the hand was achieved. 40 years later the patient suffered from a mild loss of function and dexterity. NCV demonstrated prolonged distal latencies and small sensory action potentials at all fingers. Imaging modalities as high resolution ultrasound, conventional MRI with 1,5 T, and MRI fibre tracking exams were employed to assess the fascicular nerve mor
