Percutaneous lumbar nucleotomy (PLN) showed a 79.7% success rate in patients, enabling return to work and activity. However, PLN was ineffective for severe leg pain or positive straight leg raise tests.

Area of Science:

  • Neurosurgery
  • Orthopedic Surgery
  • Minimally Invasive Procedures

Background:

  • The study evaluates the efficacy of percutaneous lumbar nucleotomy (PLN) for treating lumbar disc herniation.
  • A total of 66 procedures were performed on 63 patients between October 1984 and March 1990.

Observation:

  • Patient age ranged from 13 to 73 years (average 36.8).
  • Postoperative follow-up varied from 6 months to nearly 6 years (average 2.0 years).
  • Pre- and postoperative discograms were utilized for assessment.

Findings:

  • A high success rate of 79.7% (51 patients) was observed, with patients returning to employment and prior activity levels.
  • Six patients (9.4%) experienced unsuccessful outcomes, necessitating further surgical intervention.

  • PLN demonstrated limited effectiveness in cases of severe sciatica or extremely positive straight leg raise (SLR) signs.

    • Implications:

    • Percutaneous lumbar nucleotomy is a viable option for select patients with lumbar disc issues.
    • Careful patient selection is crucial, excluding those with severe radicular symptoms.
    • Further research may explore alternative treatments for patients unresponsive to PLN.
