Laminectomy with rhizotomy: what to know

Laminectomy removes part of the vertebral lamina to make space around the spinal cord or nerves. Rhizotomy refers to cutting or otherwise treating a selected nerve root or its branches. The exact target and purpose vary by diagnosis; it may be considered when a particular nerve pathway is contributing to severe, persistent symptoms or abnormal muscle activity.

These procedures require careful mapping of symptoms and nerve function. [Spinal Stenosis] can create pressure in the canal, and [Spondylolisthesis] can alter the position of vertebrae. Ask which symptom the rhizotomy is intended to address and what sensation or movement that nerve controls.

Discuss your medicines, allergies, previous spine procedures, and any weakness or bladder symptoms before consent. Arrange transport and support for the first part of recovery. Follow wound and walking instructions, protect the treated area from strain, and attend neurological follow-up. Numbness, altered sensation, or weakness may need specific monitoring because a nerve pathway has been treated.

Your team may compare this plan with [Endoscopic Spine Surgery] when the anatomy permits. The general [Laminectomy] page provides context for the decompression portion.

Contact the surgical team for fever, wound drainage, increasing redness, uncontrolled pain, or new or worsening weakness or numbness. Seek urgent care for loss of bladder or bowel control, numbness around the saddle area, sudden severe weakness, or breathing difficulty.

Which nerve root will be treated, and what finding identifies it? Is rhizotomy intended to change pain, spasm, or another symptom? What function could be affected? How will nerve recovery be monitored? Which postoperative changes require immediate assessment?
