As a treatment of multiple degenerative lumbar disease, there is no doubt about wide
decompressive laminectomy for neural decompression. But postlamenectomy instability
caused by wide decompression can provoke neurologic deterioratons and further
stabilization procedures may requires to improve clinical symptom. Among stabilization
procedure, posterior lumbar interbody fusion and posterior fixation with transpedicular
screw can provide immediate stability postoperatively. But the posterior fixation with
rigid rod or plate system can cause degenerative instability in adjacent segment and
hardware failure due to hyperrigidity. Therefore authors have tried posterior soft GRAF
fixation and posterior lumbar interbody fusion cages to avoid complications of rigid
systems and iliac bone graft in 124 patients with multiple degenerative lumbar disease.
The angular instability was improved from 14.9¡Æ¡¾6.4¡Æ to 3.4¡Æ¡¾3.5¡Æpostoperatively
and translational instability was decreased from 6.4mm¡¾1.1mm(p<0.001). The height of
intervertebral disc was increased from 9.8mm¡¾2.1mm to 12.2mm¡¾2.4mm significantly.
The new instability on adjacent segment was not apparent during follow-up period.
With this procedure, 88.7% of the patients were improved clinically.
Results of this study show that soft GRAF fixation and posterior lumbar interbody
fusion with cage(circumferential fusion or 360¡Æ fusion) can provide the three column
stability immediately after operation without any hardware related complications. Also, it
can give more physiologic property biomechanically than rigid fixation to degenerative
spinal column.
