Loss of the sciatic nerve may result in paralysis and sensory loss of the leg. Among indications for lower limb amputation is blunt trauma to the nerve that is feared to have no chances of recovery. Injuries of thermal in nature are thought to have an extensive damage far from the site of injury and are thus unlikely to recover. The injured nerve is likely to heal by fibrosis and scarring making it difficult for any axons to go through it. The only hope for such recovery is removal of all injured sections followed by the nerve repair with a nerve graft or nerve transfer. With advances in microsurgery more and more injured nerves that were otherwise considered unsalvageable are now routinely reconstructed with relatively good outcomes. A good proportion of this are nerve injuries of the upper limbs such brachial plexus, median, ulnar and radial nerve injuries. Compared to the upper limb nerve injuries there is little data on the outcomes of lower limb nerve injuries. The tendency towards amputation of the lower limb following blunt trauma to the sciatic nerve is much higher than the upper limb. We present a case of post traumatic thermal sciatic nerve injury that was repaired with a sural nerve graft with good outcomes.
