Microdiscectomy Surgery
Overview
Microdiscectomy is a minimally invasive spine surgery performed to relieve nerve compression caused by a herniated lumbar disc. Using specialized instruments and a surgical microscope, the surgeon removes a portion of the disc material that is pressing on the spinal nerve. The procedure is designed to alleviate leg pain, numbness, or weakness caused by sciatica or nerve root compression.
Indications
Microdiscectomy may be recommended for patients with:
- Herniated lumbar disc with radiating leg pain (sciatica)
- Numbness, tingling, or weakness in the leg or foot
- Persistent symptoms despite 6–12 weeks of conservative treatment
- Confirmed nerve root compression on imaging studies (e.g., MRI)
Procedure
Microdiscectomy is typically performed under general anesthesia and involves the following steps:
- A small incision (about 1–1.5 inches) is made in the lower back
- Muscles are gently retracted to expose the vertebra
- A portion of the lamina may be removed (laminotomy) for better access
- The herniated disc fragment compressing the nerve is removed
- The incision is closed and the patient is monitored before discharge
Risks & Considerations
While microdiscectomy is considered safe and effective, potential risks include:
- Infection or bleeding
- Nerve injury or dural tear (spinal fluid leak)
- Recurrent disc herniation
- Incomplete symptom relief
- Rarely, persistent back pain or need for future surgery
Recovery & Outcomes
- Most patients return home the same day or after one night
- Walking is encouraged within hours after surgery
- Return to light activities in 2–4 weeks; more strenuous activity after 6 weeks
- Most patients experience rapid relief of leg pain with high long-term success rates
