• STUDY DESIGN
    • A description of the technique for lumbar microdecompression and a prospective study of the outcomes.
  • OBJECTIVE
    • To describe and analyze a technique that affords an excellent decompression while minimizing damage to surrounding tissues.
  • SUMMARY OF BACKGROUND DATA
    • Commonly used techniques of lumbar decompression that include bilateral takedown of paraspinal musculature and aggressive bony resection can result in significant iatrogenic sequelae. A less destructive alternative is needed.
  • METHODS
    • Unilateral limited takedown of multifidus was undertaken, and ipsilateral decompression performed. The contralateral side then was addressed under the midline structures with microscopic visualization--thereby preserving the supra-/interspinous ligament complex and the contralateral musculature. Thirty consecutive patients undergoing the procedure were analyzed prospectively and after a follow-up period by independent observers using a modified validated functional outcome score and patient satisfaction measures.
  • RESULTS
    • The technique affords an excellent decompression while minimizing destruction to tissues not directly involved in the pathologic process. Functional outcome scores doubled, and 87% of patients reported high satisfaction rates.
  • CONCLUSIONS
    • Lumbar microdecompression is a minimally invasive technique that appears to provide excellent functional outcomes.
