Prolapsed intervertebral disc with sciatica: the role of common peroneal nerve block.

A total of 210 patients of Lumbar disc prolapse with sciatica were given common peroneal block by infiltrating 2% xylocaine around the common peroneal nerve 3 cm below the head of fibula on the affected side. After receiving the block the pain decreased on from grade 2.99 +/- 0.46 to 0.91 +/- 0.99, and straight leg raising increased from 32.1 +/- 12.55 to 59.66 +/- 12.11 degrees. The method, as an outpatient procedure, has been found to be simple and useful in the patients of sciatica with prolapsed lumbar intervertebral disc potentially appropriate for a low-resource setting.
