Abstract:

BACKGROUND: The modified autogeneous bone fusion refers to the combination of cancellous bone and cortical bone. Their combination plays a complementary role in lumbar spinal fusion. This can ensure the fusion rate and reduce the excessive loss of intervertebral height.
OBJECTIVE: To study the curative effect of internal fixation by nail-stick system and posterior lumbar interbody fusion with modified autogeneous bone for lumbar degenerative disease.
METHODS: According to different operation methods, 60 patients with lumbar degenerative disease were equally divided into modified group and control group. The modified group was treated with internal fixation by nail-stick system and posterior lumbar interbody fusion with modified autogeneous bone, while control group was treated with internal fixation by nail-stick system and Cage posterior lumbar interbody fusion. All patients were detected at 3, 6, 12 months of follow-ups. The postoperative complications, improvement rate of low back pain, intervertebral height and lumbar lordosis angle after operation were observed and compared in two groups.
RESULTS AND CONCLUSION: All the patients have better life quality and significant improvement in low back pain after surgery, when compared to before surgery. Fewer postoperative complications happen to patients in the modified group. There is no significant difference in intervertebral height and lumbar lordosis angle between the two groups. Internal fixation by nail-stick system and posterior lumbar interbody fusion with modified autogeneous bone is similar to internal fixation by nail-stick system and Cage posterior lumbar interbody fusion, but modified autogeneous bone has less complication than Cage in a long-term follow-up.
