What is Microdiscectomy?
Microdiscectomy is a minimally invasive surgical procedure designed to relieve pain caused by a herniated disc pressing on a nerve root. During the procedure, Dr. Rastegar removes the portion of the disc that is compressing the nerve, providing relief from pain, numbness, and weakness.
Using specialized microscopes and instruments, Dr. Rastegar can perform this surgery through a small incision (typically 1-1.5 inches), minimizing damage to surrounding muscles and tissues. This approach results in less pain, faster recovery, and better outcomes compared to traditional open spine surgery.
Microdiscectomy is most commonly performed for lumbar (lower back) herniated discs but can also be performed in the cervical (neck) region. It's considered the gold standard surgical treatment for herniated discs that haven't responded to conservative care.
When is Microdiscectomy Recommended?
Dr. Rastegar may recommend microdiscectomy if you have:
- Leg pain (sciatica) that hasn't improved with 6-12 weeks of conservative treatment
- Significant weakness in your leg or foot
- Difficulty standing or walking due to nerve compression
- Loss of bowel or bladder control (this is a medical emergency requiring immediate surgery)
- Pain that severely impacts your quality of life and daily activities
- MRI confirmation of a herniated disc compressing a nerve
The Microdiscectomy Procedure
Anesthesia
The procedure is performed under general anesthesia, so you'll be asleep and comfortable throughout.
Incision
Dr. Rastegar makes a small incision (typically 1-1.5 inches) over the affected disc. The muscles are gently moved aside rather than cut.
Accessing the Spine
Using a surgical microscope for magnification and precision, Dr. Rastegar carefully accesses the herniated disc.
Removing the Herniation
The portion of the disc pressing on the nerve is carefully removed. Any loose disc fragments are also removed to prevent future problems.
Closure
The incision is closed with sutures. The entire procedure typically takes 45-90 minutes.
Same-Day Discharge: Most patients go home the same day as surgery, typically 2-4 hours after the procedure.
Recovery & Expected Results
Immediate Recovery (Days 1-7)
- Many patients experience immediate relief from leg pain after surgery
- Light walking is encouraged starting the day of surgery
- Avoid bending, lifting, and twisting during this period
- Pain medication helps manage any discomfort
Short-Term Recovery (Weeks 2-6)
- Gradual return to daily activities
- Physical therapy may begin to strengthen back muscles
- Most patients can return to sedentary work within 2-4 weeks
- Driving is typically allowed after 1-2 weeks (when off narcotics)
Full Recovery (Weeks 6-12)
- Return to most normal activities, including moderate exercise
- Those with physically demanding jobs can typically return by 6-12 weeks
- Continue core strengthening and proper body mechanics
Success Rate
Microdiscectomy has an excellent success rate, with 85-95% of patients experiencing significant improvement in leg pain. Patient satisfaction is very high with this procedure.
Advantages of Microdiscectomy
Frequently Asked Questions
How long does microdiscectomy surgery take?
The surgery typically takes 45-90 minutes, depending on the specific case. You'll spend additional time in recovery before being discharged home the same day.
Will I need physical therapy after surgery?
Most patients benefit from physical therapy starting 2-4 weeks after surgery. Dr. Rastegar will recommend a personalized rehabilitation program to strengthen your back and prevent future problems.
Can the herniated disc come back?
There is a 5-10% chance of recurrent disc herniation. However, Dr. Rastegar uses advanced techniques to minimize this risk. Following post-operative guidelines and maintaining good spine health are important for long-term success.
What are the risks of microdiscectomy?
As with any surgery, there are risks including infection, bleeding, nerve injury, and recurrent herniation. However, serious complications are rare. Dr. Rastegar will discuss all risks and benefits with you during your consultation.
Will I have a scar?
Yes, but the scar is typically very small (1-1.5 inches) and fades significantly over time. The minimally invasive approach results in a much smaller scar compared to traditional open surgery.
When can I return to work after microdiscectomy?
Return to work depends on your job requirements. Those with desk jobs can often return within 2-4 weeks, while those with physically demanding jobs may need 6-12 weeks. Dr. Rastegar will provide specific guidance based on your occupation.
