Objective To discuss the effect of vertebral lamina fenestration with small incision for the treatment of lumbar disc herniation(LDH).Methods Random sample of 120 cases of patients with LDH in different intervertebral spaces form January 2001 to January 2008 were subjected to operations with conventional surgical instruments. A posterior central mini-incision about 2.5-4cm was made,a mini-window about 1.5cm ×1.5cm opened in the interstice between the consecutive vertebral plates,and the nerve canal was depressed. Then,the vertebral pulp was removed. The whole operative time was 30min to 1.5h (mean 1h). Results All the patients were followed up for 6 months to 8 years (mean 24 months). According to the Nakai criteria,the outcome was excellent in 82 cases,good in 30 cases,fair in 5 cases and poor in 3 cases. The excellent-good rate was 93.3%. Recurrence occurred in 3 patients 6 months after operation. Conclusion The method of small incision technique is safe and effective with the advantages of minimal invasion,short operative time,less blood loss,minimal damage to spinal structure,more rapid recovery,out-of-bed activity in short time and fewer complication.
