Conditions

Lumbar Facet Arthrosis, Nerve Degeneration

Brief summary

The purpose of the study is to understand the composition of the nerves supplying the facet joints in low back.

Detailed description

After written informed consent, the nerves supplying the facet joints - lumbar dorsal rami and its medial branches, will be harvested when they are exposed during spinal surgery. These nerves will be fixed, washed and further dissected to enable smaller sections. The cut section will be stained and subjected to analysis of overall cross-sectional area and presence of connective tissue sheaths under light microscope.

Interventions

PROCEDURESpinal surgery

In participants who undergo elective lumbar spinal surgery and consented for research, the medial branch and dorsal rami will be harvested for histological analysis.

The harvested nerves will be fixed, cut into smaller sections. Analysis of macroscopic and light microscopic sections will be carried out
