Abstract:
Objective To observe the therapeutical effect by using pedicle screw and interbody fusion cage,and compare with posterior interbody simple autogenous bone graft. Methods From August 2006 to January 2009,46 cases of lumbar spondylolisthesis patients were treated by using pedical screw internal fixation system, including 24 cases of cage-graft (group A), 22 cases of interbody simple autogenous bone graft (group B), efficacy evaluation using JOA evaluation standard, and measured lumbar olisthe reset rate, relative intervertebral space height and lumbosacral angle of recovery and observed fusion rate through the preoperative and postoperative follow-up X-ray films. Results All the patients' waist pain symptoms relieved after operative reduction. At 18 months of follow-up , group A of lumbar olisthe reset rate was 94.7%, relative intervertebral space height was (74.93 ± 7.85)% ,lumhosacral angle was 36.6° ± 3.6° ,meanwhile group B was 89.9%, (68.72 ± 12.40)%,39.3°± 5.6°. There were significant differences between two groups (P<0.05). Bone graft fusion rate in group A was 95.83% (23/24), in group B was 90.91%(20/22), there was significant difference between two groups (P < 0.05). Conclusion Pedicle screw system and interbody cage-graft in treatnent of lumber spondylolisthesis can effectively prevent the loss of reduction,mid and long-term effects are satisfactory,it is a stable and reliable method.
