Abstract:
Objective Currently there is little study on the K-Rod pedicle fixation system in the treatment of far lateral lum-ber disc hernaition with multiple segment degeneration.The study was to compare the short-term efficay of K-Rod pedicle dynamic fixa-tion system and lumbar fusion for far lateral lumber disc herniation with multiple segment degeneration. Methods Retrospective a-nalysis were made on 56 patients with lumbar intervertebral disc herniation with multiple segment degeneration who received operation in General Hospital of Shenyang Military Region from January 2010 to October 2012.They were divided into K-Rod group (combined treatment of lumbar fusion and adjacent degenerative segment unfusion) and traditional fusion group according to different treatments. 28 patients in K-Rod group were treated with K-Rod pedicle dynamic fixation system and 28 cases in traditional fusion group were trea-ted with traditional lumbar fusion and internal fixation.Comparative analysis were made on the indexes before and after operation be-tween two groups, including Oswestry disability index, visual analogous scale (VAS) ,improvement rate of low back pain, postopera-tive lumbar spine X-ray, operation time, intraoperative blood loss and postoperative average length of stay. Results 12 to 24 months follow-up were achieved on 56 cases.The Oswestry function score and visual analog scale for both groups were improved significantly at 12 months after operation, and the difference was of statistical significance (P<0.05).Oswestry function scores and vis-ual analog scales between two groups were of no significant difference either before operation or after operation (P>0.05), while the average operation time ([119.6 ±14.2] min vs [155.5 ±17.5]min), the average blood loss ([235.5 ±32.5] mL vs [367.5 ±29. 5] mL), the average length of stay (ALOS) ([10.5 ±2.2] vs [14.2 ±2.6]d) between K-Rod group and traditional fusion group were of significant difference(P<0.05). Conclusion In the treatment of far lateral lumber disc hernaition with multiple segment degeneration, the K-Rod pedicle dynamic fixation system atrributes to less intraoperative blood loss, shorter operation time and little postoperative effect on lumbar spine mobility.
