If you're considering surgery for a lumbar disc herniation at the L5-S1 level, one risk you'll want to be aware of is if you're at an increased risk of developing a recurrent herniation in the same spot after surgery.

Is there an increased risk of recurrent lumbar disc herniation after surgery?

A recent study examined the results of 467 patients who had surgery for a lumbar disc herniated and assessed the preoperative risk factors for developing a recurrent disc herniation.

In this study, 39 patients—or 8.3 percent of patients—developed another disc herniation in the same spot (in the disc at the L5-S1 level) after surgery. This rate of recurrence is consistent with prior clinical studies.

The study examined a number of factors, including:

  • Radiologic parameters, such as such as disc height, disc degeneration, and more
  • Clinical parameters, such as the patient's age, BMI, diabetes, smoking, and more

The study concluded that the following factors contributed to increased risk of developing a recurrent disc herniation after discectomy surgery:

  • Several biomechanical factors, including moderate disc degeneration with preserved disc height, as well as a few other detailed anatomical factors
  • Being male
  • Having a large tear in the annulus

If you're considering having a microdiscectomy for symptoms from a lumbar herniated disc, talk to your surgeon about your individual risk factors so that you are well informed before the surgery.
