What Percentage of Microdiscectomies Are Successful?

Written by The Barricaid Team | Aug 14, 2024 7:46:00 AM


Microdiscectomy is a minimally invasive surgical procedure used to treat herniated discs in the spine. This procedure involves removing a small portion of the herniated disc material that is pressing on a nerve root or the spinal cord. Unlike traditional open surgery, microdiscectomy uses smaller incisions and specialized tools, resulting in less tissue damage and faster recovery times. 

For those suffering from persistent back pain and sciatica, this operation can offer hope for relief. But as with any medical intervention, patients often wonder about its effectiveness. In this article, you will learn about the success rates of microdiscectomies, factors that influence outcomes, and what patients can expect during recovery.

Success Rates: The Numbers

When it comes to microdiscectomy success rates, the numbers are generally encouraging:

  • Short-term success – Approximately 80–90 percent of patients report significant pain relief and improved function within the first few weeks following surgery.
  • Long-term outcomes – About 70–80 percent of patients maintain positive results for several years post-surgery.
  • Repeat surgery rates – The need for repeat surgery within 10 years is relatively low, ranging from 5–15 percent of cases.

It is important to note that “success” can be defined differently across various studies. Some focus on pain reduction, while others consider factors like return to work or overall quality of life improvement.

Factors Influencing Success Rates

Several factors can impact the success of a microdiscectomy:

  • Patient selection – Proper diagnosis and patient selection are crucial. Those with clear disc herniation and corresponding symptoms tend to have better outcomes.
  • Surgeon experience – The skill and experience of the surgeon play a significant role in the procedure’s success.
  • Timing of surgery – Patients who undergo surgery within 6–12 months of symptom onset often have better results than those who wait longer.
  • Patient compliance – Following postoperative instructions, including physical therapy and activity restrictions, can greatly influence long-term success.
  • Preexisting conditions – Factors such as obesity, smoking, and certain medical conditions may affect healing and overall outcomes.

Comparing Microdiscectomy to Other Treatments

To put microdiscectomy success rates into perspective, it is helpful to compare them with other treatment options:

  • Conservative treatments – While many patients improve with nonsurgical approaches like physical therapy and pain management, microdiscectomy often provides faster and more complete relief for appropriate candidates.
  • Traditional open surgery – Microdiscectomy generally has similar or slightly better success rates compared to open discectomy, with the added benefits of faster recovery and lower complication rates.
  • Newer minimally invasive techniques – Some emerging techniques show promise, but microdiscectomy remains the gold standard for many surgeons due to its proven track record and well-established success rates.

Potential Complications and Risks

While microdiscectomy is generally safe and effective, it is important to be aware of potential risks:

  • Infection – Although rare (occurring in less than 1 percent of cases), surgical site infections can occur.
  • Dural tear – This complication, where the membrane covering the spinal cord is damaged, happens in about 1–3 percent of cases.
  • Recurrent disc herniation – As mentioned earlier, a small percentage of patients may experience recurrence of their herniated discs.
  • Nerve root damage – While extremely rare, there is a slight risk of nerve injury during the procedure.

Understanding these risks is crucial for patients making informed decisions about their treatment options.

The Recovery Process

A successful microdiscectomy is not just about the surgery itself but also the recovery process. Here is what patients can typically expect:

  • Hospital stay – Most patients go home the same day or after one night in the hospital.
  • Initial recovery – Many experience immediate relief from leg pain, though some back pain and discomfort at the incision site are normal.
  • Activity restrictions – Patients are usually advised to avoid bending, lifting, and twisting for several weeks.
  • Physical therapy – A structured rehabilitation program often begins 2–6 weeks after surgery to increase strength and flexibility.
  • Return to work – Many patients can return to sedentary jobs within 1–2 weeks, while those with more physically demanding occupations may need 4–6 weeks.
  • Full recovery – Most patients achieve maximum improvement within 3–6 months, though everyone’s healing process is unique.

Maximizing Your Chances of Success

If you are considering a microdiscectomy, there are steps you can take to increase your chances of a positive outcome:

  • Choose an experienced surgeon – Look for a board-certified spine surgeon with a track record of successful microdiscectomies.
  • Follow preoperative instructions – This may include stopping certain medications or making lifestyle changes like quitting smoking.
  • Commit to rehabilitation – Take your postoperative care seriously, including physical therapy and activity modifications.
  • Maintain a healthy lifestyle – Good nutrition, weight management, and regular exercise can contribute to long-term spine health.
  • Set realistic expectations – While many patients experience significant improvement, it is important to have realistic goals and understand that some residual symptoms may persist.

Microdiscectomy has proven to be a highly successful procedure for many patients suffering from herniated discs. With success rates ranging from 70–90 percent, depending on how success is defined and measured, it offers hope for those who have not found relief through conservative treatments. However, as with any surgical procedure, it comes with potential risks and requires careful consideration.

The decision to undergo a microdiscectomy should be made in consultation with a qualified spine specialist, taking into account your specific condition, overall health, and personal goals. By understanding the factors that contribute to successful outcomes and committing to proper pre- and postoperative care, you can maximize your chances of joining the majority of patients who find significant relief and improved quality of life following this procedure. A thorough discussion with your healthcare provider is the best way to determine if a microdiscectomy is the right choice for you and to set appropriate expectations for your individual case.

Although microdiscectomy surgery is generally a very successful procedure, a hole is left in the outer wall of the disc. Patients with a large hole in the outer ring of the disc are more than twice as likely to reherniate after surgery. A new treatment, Barricaid, which is a bone-anchored device proven to reduce reherniations, was specifically designed to close the large hole often left in the spinal disc after microdiscectomy. In a large-scale study, 95 percent of Barricaid patients did not undergo a reoperation due to reherniation in the 2-year study timeframe. This treatment is done immediately following the discectomy—during the same operation—and does not require any additional incisions or time in the hospital.
