Abstract

BACKGROUND:

There has been a controversy concerning whether fusion or not is applied in the treatment of lumbar disc herniation.

OBJECTIVE:

To compare the curative effects of instrumented fusion and simple fenestration discectomy in the treatment of bulged lumbar disc herniation.

METHODS:

Totally 152 patients with bulged lumbar disc herniation treated between December 2004 and December 2009 in Zhujiang Hospital were reviewed. Fifty-five cases underwent simple fenestration discectomy (simple fenestration group), 97 cases received nucleus pulposus annulus extraction, instrumented intervertebral fusion and pedicle screw fixation (fusion group). Follow-up was performed termly after operation.

RESULTS AND CONCLUSION:

X-rays showed that the intervertebral height of simple fenestration group was significantly reduced at 6 months and 6 years after operation whereas the intervertebral height of the fusion group was increased at these two time points (P < 0.05). There was no significant difference in visual analogue score and Oswestry score before and 6 months after operation between two groups (P > 0.05). However, 6 years later, the mean visual analogue score and Oswestry score in the fusion group were significantly lower than that in the simple fenestration group (P < 0.01). For bulged disc herniation, nucleus pulposus annulus extraction, instrumented intervertebral fusion and pedicle screw fixation have better long term results compared with simple fenestration discectomy.
