Abstract:
Objective To discuss the short-term clinical effect of K-Rod pedicle dynamic fixation system for multiple segmental lumbar degeneration. Methods From January 2010 to October 2012,28 patients with multiple segmental lumbar degeneration who were accepted K-Rod pedicle dynamic fixation system were retrospectively reviewed. The short-term clinical effect were based on Oswestry disability index score,visual analogous scale ( VAS) ,improvement rate of low back pain,postoperative lumbar hyperextension, hyperbend X-ray film lumbar ROM value ( lumbar flexion mobility) ,average operation time, intraoperative blood loss. Results All of 28 cases were achieved 12 ~24 months follow-up,the difference of Oswestry disability index score and visual analogous scale ( VAS) between 12 months postoperatively and preoperatively were statistically significant,the improvement rate of low back pain was (87. 0 ± 2. 0)%,the average operation time was (99. 6 ± 16. 2) minutes,the average blood loss was (70. 5 ± 31. 5)mL,the average length of stay(ALOS) was (11. 2 ± 2. 6) days after sur-gery. Conclusion K-Rod pedicle dynamic fixation system in the treatment of multiple segmental lumbar degeneration can obtain satisfactory short-term clinical effect.
