Abstract:
Objective To analyse the relationship between lumbar discectomy outcomes and herniated type and annular integrity. Methods Two hundred and sixty patients who underwent conventional posterior discectomy for lumbar herniated disc were reviewed and followed-up for 6-14 years, with an average of 8.5 years. The criteria of enrolled patients include: all of the cases with low lumbar disc herniation at a single level, laterally protruded disc(one side sciatica) without spinal canal stenosis. Four categories of intraoperative findings were found basing on the defect size of annular and extruded fragments, and postoperative outcomes was compared statistically. Results The patients with larger disc fragments and minimal annular defects had the better outcomes and lowest incidence of recurrence after surgery. On the contrary, small fragments with massive annular defects did worse by comparison. Conclusion The outcomes of lumbar discectomy have close relationship with herniation type and annular integrity. Patients with mild clinical symptoms, small and broad-based disc herniations should be exempted from open discectomy. If open discectomy unavoidable, annular integrity and bony stability should be preserved as much as possible.
