What should you know about microdiscectomy and fusion?

A microdiscectomy uses a focused approach to remove the part of a disc that irritates a nerve. It may be considered when a [Herniated Disc](/conditions/herniated-disc/) causes matching leg symptoms such as [Radiating Leg Pain](/symptoms/radiating-leg-pain/) or [Sciatica](/conditions/sciatica/). Fusion uses bone graft and implants to hold selected vertebrae together while the segment heals; it is a separate structural decision, not an automatic addition to discectomy. A [Surgical Microscope](/technology/surgical-microscope/) may help the surgeon see the nerve through a smaller operative field.

Ask which symptom the operation is intended to improve and what imaging shows. Review medicines, nicotine use, health conditions, and home support before surgery. Recovery commonly includes short walks, careful position changes, incision care, and a gradual return to activity. Physiotherapy may be introduced when appropriate. Discuss whether [Endoscopic Spine Surgery](/treatments/spine-care/endoscopic-spine-surgery/) or an [Epidural Steroid Injection](/treatments/spine-care/epidural-steroid-injection/) could fit your situation, and what role [Physiotherapy](/treatments/physiotherapy-and-rehabilitation/physiotherapy/) has before or after surgery.

Seek urgent care for new weakness, numbness around the groin, loss of bladder or bowel control, severe breathing difficulty, or rapidly worsening pain. Call the surgical team for fever, increasing wound redness, drainage, wound opening, or a new severe headache that changes with position.

Is nerve pressure the only problem, or is the segment unstable? Why would fusion help me? What are the expected restrictions and rehabilitation stages? What symptoms should improve first? What is the plan if pain or weakness continues?
