Posterior Spinal Hemi- Anaesthesia for Tendon Transfer in Patient with Foot Drop- Case Report

In surgery for foot drop, regional anaesthesia, with selective sensory block and preserved motor function, can be of immense benefit to the surgeon. It allows patient to move foot on command, thus helping in identifying functional tendons, and determine the efficacy of transplanted tendon intraoperatively. We describe a simple and effective technique to achieve this, using hypobaric local anaesthetic drug for spinal anaesthesia and keeping the patient prone in jack-knife position for 15 minutes This allows only sensory posterior nerve roots to be blocked, sparing the motor anterior nerve-roots.
