Central lumbar disc herniation (CLDH) outcomes are poorer than other types. Surgical approach and CLDH subcategories (CMP vs. CCDH) showed minimal impact on results.

Area of Science:

  • Neurosurgery
  • Spinal Surgery
  • Orthopedic Surgery

Background:

  • Central lumbar disc herniation (CLDH) may be associated with poorer surgical outcomes compared to other lumbar disc herniations.
  • The specific anatomical location of CLDH might influence postoperative results.

Purpose of the Study:

  • To evaluate clinical outcomes in patients with CLDH.
  • To determine if surgical approach (unilateral vs. bilateral) affects outcomes.
  • To compare outcomes between central mass prolapse (CMP) and central contained disc herniation (CCDH) subcategories.

Main Methods:

  • Retrospective analysis of 40 patients diagnosed with CLDH between 1990 and 1997.
  • Patients underwent microdiscectomy via unilateral or bilateral fenestrations.
  • Standardized questionnaires were used for long-term follow-up by an unbiased observer.

Main Results:

  • 85% long-term follow-up (mean 3.3 years) was achieved for 34 patients.
  • Overall success rate was 68%, with 24% excellent, 44% good, 24% fair, and 9% poor results.
  • No significant differences in outcomes were found between CMP and CCDH, nor between unilateral and bilateral surgical approaches.

Conclusions:

  • Postoperative outcomes for CLDH are generally poorer than for other lumbar disc herniations.
  • The anatomical position of CLDH, affecting disc architecture, is a likely reason for poorer outcomes.
  • Surgical approach and CLDH subcategories have minor impact; interlaminar fenestrations are suitable for fragment removal.
