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.

Objective To discuss the clinical effect and the notes of atlas lateral mass screws combined with posterior epistropheus ped-icle screws for the treatment of atlantoaxial joint instability. Methods In our hospital from January 2006 to January 2011,48 cases of atlan-toaxial joint instability accepted operation of the atlas lateral mass screws combined with epistropheus pedicle screws were analyzed. Results All patients with follow-up time 12~24 months,an average of 17 months,were achieved primary healing and atlanto-axial intervertebral osse-ous healing. Besides postoperative neck pillow area pain improved and nerve function get a degree of recovery,there was no inner fixed damage cases. Complications of operation include venous plexus hemorrhage was in 2 cases,cervical occipital pain and numbness increase in 3 cases,cere-brospinal fluid leak in 2 cases,vertebral artery extrusion occlusion after cerebral ischemic symptoms in 1 case. Conclusion Combination of atlas lateral mass screws and posterior epistropheus pedicle screws technique is one of the effective means of treatment of atlantoaxial joint instabili-ty and can obtain satisfactory clinical effect. Standard operation performance is the key to reduce or even eliminate surgical complications.

Objective The purpose was to compare the biomechanical characteristics of new percutaneous guide wire and conventional wire in cadaveric spines,and to evaluate the new percutaneous guide wire's efficacy and safety in a clinical trial.Methods Compared the push-out and penetration forces of the new percutaneous guide wire and conventional wire in fresh cadaveric lumbar spines from L1 to L5.And analyzed the related complications of new percutaneous guide wire by clinical experiment.Results Push-out forces caused the spiral part of the new percutaneous guide wire to bend or spread,so as to resist the anterior migration of the guide wire.The mean push-out forces of the new percutaneous guide wire and conventional wire were (15.5-+ 1.9) N and (5.7 ± 0.8) N respectively (P < 0.01),and the mean penetration forces were (69.1 ±4.2) N and (37.1 ±4.8) N respectively (P <0.01).There was no wire breakage or anterior-wall penetration in the clinical trial of 222 new percutaneous guide wire.Conclusion The mean push-out and penetration forces of the new percutaneous guide wire were approximately 2 to 3 times greater than those of conventional wire.The new percutaneous guide wire effectively prevented guide-wire anterior migration and penetration of the anterior vertebral-body wall.The new percutaneous guide wire device could effectively improve the safety of percutaneous pedicle screw insertion procedures for patient with osteoporosis.

Objective To explore the effect of paraspinal approach and posterior median approach for one -stage decompression recon-struction in the treatment of thoracolumbar spine fracture and dislocation .Methods From January 2012 to January 2014, 60 patients with thoracolumbar spine fracture and dislocation who were admitted and treated in our hospital were selected as the research objects .All patients received one-stage decompression reconstruction for treatment .According to the methods of approach , the patients were divided into the ob-servation group and the control group .The 30 cases in observation group were treated by paraspinal approach while the other 30 cases in con-trol group were treated by posterior median approach .Visual analogue score ( VAS) was applied .The status of surgery , recovery of centrum height, changes of Cobb angle as well as the occurrence rate of postoperative complications in the two groups were recorded .Results In the observation group, the operative time, time in bed and length of stay were (89.16 ±11.63) min, (39.75 ±8.69) h and (3.96 ±1.04) d respectively, which were shorter than those in the control group .The intraoperative blood loss was (89.64 ±13.62) mL which was lower than that in the control group and the difference was significant (P<0.05).One week after operation, the anterior and posterior height of centrum in the observation group increased significantly while Cobb angle significantly reduced .Compared with those before the treatment , the difference was significant (P<0.05).The maximum coronary diameter and maximum sagittal diameter of paraspinal muscles in the ob -servation group after the treatment were (48.96 ±5.34)mm and (18.16 ±6.74)mm respectively, which were significantly higher than those in the control group and the difference was significant (P<0.05).The incidence of lumbar and back pain in the observation group was 3.33%which was lower than 23.33%in the control group and the difference was statistically significant (P<0.05).Conclusion To carry out decompression reconstruction through paraspinal approach can reduce the the pain degree of patients and the incidence of lumbar and back pain after operation .

Objective To expore the difference between magnetic resonance image ( MRI) expression of spinal tuberculosis and brku-cellare spondylitis. Methods Retrospectively analyzed the clinical data of 10 patients with tuberculous spondylitis and 12 patients with bru-cellar spondylitis from Jan. 2012 to Oct. 2013. All the patients were scanned by MRI, and the expression difference of MRI were compared. Results The vertebral body of spinal tuberculosis was destroyed severely, and it often accompanied by the kyphosis and multiple-level para-vertebral abscess, and even adjacent organs tuberculosis. The vertebral body of brucellar spondylitis was destroyed lightly,and the abscess is often limited. Conclusion We can distinguish spinal tuberculosis and brucellar spondylitis by the typical difference of the expression of MRI.
