Lumbar Laminectomy

Removal of bone, the lamina, which is the posterior ring of the spinal canal.

This allows for decompression of the spinal canal and nerve roots being compressed.

Using a high speed drill, the lamina is drilled away to expose the underlying ligamentum flavum.

The ligamentum flavum is also removed to expose the underlying spinal canal and the existing nerve roots. The spinal canal contains the thecal sac, which houses the cauda equina (collection of nerves) that eventually turn into the nerves that go down your legs providing movement and sensation in your legs.

By decompressing the thecal sac and the nerve roots, this can alleviate symptoms in a patient’s legs.
