[Treatment of spondylolisthesis with pedicle screw instrumentation and anterior or posterior lumbar interbody fusion].
OBJECTIVE
To investigate the treatment of spondylolisthesis with pedicle screw instrumentation and anterior or posterior lumbar interbody fusion.


METHODS
26 patients, 14 males and 12 females, underwent spinal instrumentation with RF or SOCON instrumentation and anterior or posterior interbody fusion with TFC. Among them, 6 patients underwent RF instrumentation and posterior interbody fusion with TFC, 15 SOCON instrumentation and posterior interbody fusion with TFC, and 5 RF instrumentation and anterior interbody fusion with composite cortical ring.


RESULTS
All the patients were followed up for an average of 22 months (range 6 - 18 months) after operation. The reduction of spondylolisthesis was 88%, and the fusion rate 89%. There was no recurrence of spondylolisthesis.


CONCLUSIONS
High quality SOCON instrumentation may be reliable for the treatment of spondylolisthesis. Implantation of TFC into the interbody space can stabilize the fused segments, prevent the collapse of the interbody space, avoid bone resorption, remain or increase the heights of the interbody space, facilitate the union of the fused segments, and allow early mobilization.
