Objective:
To explore the surgical therapy for lumbar disc herniation (LDH).
Methods:
Under local anesthesia by blocking the posterior branches of spinal nerves, 3 surgical approaches were adopted in 6 815 LDH cases, namely discectomy by lateral and interlamina access, double fenestration and enhanced decompression for broad central LDH, and removal of nucleus pulposus with small incision and fenestration.
Results:
Follow-up study was conducted in 5 324 cases for the duration varying from 6 months to 14 years, averaging 6.3 years. Excellent results were achieved in 4 260 cases (80.02%), good in 855 cases (16.06%) with another 209 cases (3.92%) showing symptomatic improvement. X-ray examination in these cases revealed narrowed intervertebral spaces of different degrees without lumbar instability or spondylolisthesis.
Conclusion:
In comparison with conventional approaches, the 3 surgical approaches for LDH management may preserve the utmost integrity of the posterior lumbar structures and cause less traumatic injuries with shortened operation time and quick recovery.
