Microneurosurgical treatment for relief of spasticity of limbs in brain injury patients

Abstract

Objective To study the effectiveness of microneurosurgical treatment for relief of spasticity of limbs in brain injury patients. Methods 21 patients (50 limbs) of spasticity duo to brain injury were treated by microsurgical selective peripheral neurotomy from July 2006 to July 2008. The peripheral nerves included: tibial, musculocutaneous, median, ulner, and lumbosacral posterior spinal nerves. Results At follow up evaluation( mean duration: 12. 6 months), this study showed that 100% cases experienced disappearance or notable regression of the spasticity right after operation, and the relief percentage in follow - up duration was 98%. The improved motor capacities was found in 86% cases in follow - up duration. Better quality of life was found in 95% cases by follow - up studying. Postoperative complications included dysaesthesias and pain of limbs in 26 limbs (52%), muscle weakness in 18 (36%). All the complications were relieved during follow- up period. There was 1 limb (2%) of recurrence of spasticity. Conclusions Selective peripheral neurotomy is an effective and safe microsurgical method for the treatment of spasticity of limbs in brain injury patients. The proper choice of cases and operation time and long time regular postoperative rehabilitation are keys to gain good effects.
