A second microdiscectomy for lumbar disc herniation offers significant pain relief and return to work for most patients. Key factors for success include preoperative job status and timely reoperation.

Area of Science:

  • Neurosurgery
  • Orthopedics
  • Spinal Surgery

Background:

  • Microdiscectomy is a standard treatment for lumbar disc herniation.
  • Few studies have evaluated outcomes of repeat microdiscectomy at the same spinal level.

Purpose of the Study:

  • To review outcomes of 55 patients undergoing a second microdiscectomy at the same location.
  • To identify factors associated with improved outcomes after repeat lumbar microdiscectomy.

Main Methods:

  • Retrospective review of 55 patients who had a second microdiscectomy at the same spinal level.
  • Analysis of patient data including demographics, symptom duration, operative details, and outcomes.

Main Results:

  • 86% reported complete/partial relief of pain, 88% relief of sciatica, 85% relief of back pain.

  • 100% returned to work within an average of 7 weeks; 89% were glad they had the second operation.
  • Preoperative job status, symptom recurrence interval, and second operation duration (<90 min) were key predictive factors.

    • Conclusions:

    • Repeat microdiscectomy at the same spinal level is effective for lumbar disc herniation.
    • Patient selection and surgical timing are crucial for successful outcomes in revision microdiscectomy.
