Reconstruction of the human median nerve in the forearm with the Neurotube™

Reconstruction of the median nerve in the forearm traditionally has required multiple interfascicular interposition autologous nerve grafts. Recovery of two-point discrimination, even in young adults, has been reported rarely. Two patients, aged 43 and 61, are reported with 5-year follow-up of median nerve reconstruction in the distal forearm in which multiple interposition bioabsorbable polyglycolic acid conduits (Neurotube™) were used to bridge the 3-cm nerve defects. Four separate 2.3-mm diameter, 4.0-cm long conduits were used in each patient. Sensory re-education was used for rehabilitation. Each patient recovered two-point discrimination with good localization in the thumb, index, and middle finger by 2 years after the nerve reconstruction. Both patients recovered abductor pollicis brevis function.
