Improved Neurotization in High Peripheral Nerve Injury: Side to Side H-shaped Nerve Graft at the Most Distal Part of an Injured Extremity in a Rabbit Model.

Background: We aimed to investigate the effects of nerve repair by setting a side-to-side (H-shaped) nerve graft on the most distal part of the damaged nerve to the adjacent intact nerve to accelerate its regeneration in the end organ.

Methods: This pure experimental study was done on the lower extremities of two groups of rabbits in Animal Laboratory Department, 15 Khordad Hospital Tehran, Iran. In both groups, the sciatic nerve at the proximal part of the extremity below the superficial femoral branch was first cut and then repaired.
