Objective To describe the up-to-date development in spine and spine cord injuries. Methods To summarize the cl inical and basic research on spine and spine cord injuries were summarized by reviewing papers and combining them with our own experience. Results The occi pitocervical and atlantoaxial fusions by the pedicle or the lateral mass screw were widely used to treat the upper cervical fractures. The anterior cervical plate, posterior pedicle or lateral mass screw fixation techniques were used in treatment of lower cervical fractures. The cl inical appl ication of artificial cervical disc replacement showed the good biomechanical results in treatment of serious cervical disc diseases. However, there were no unified criteria for selection of the surgical approach, fixation level, and fusion model in the treatment of thoracolumbar spine fractures. Lumbar posterior dynamic fixation and artificial disc replacement for treatment of degenerative lumbar disc diseases provided the biomechanical stabil ization and reduced the morbidity of adjacent segment diseases, but there was lack of long-term follow-up results. The basic research in spine cord injuries, especially in apoptotic signal pathway, made great progress. The biological treatment including cell transplantation and gene therapy provided the sol id theoretical foundation for cl inical appl ication. Conclusion The reparative and reconstructive development in spine and spine cord injuries has made great progress in recent years.
Objective To study the clinical effects of the artificial vertebral body of the biomimetic nanohydroxyapatite/polyamide 66 (nHA/PA66) compositefor the structural reconstruction and the height restoring of the vertebral body in the thoracolumbar fractures by the anterior surgical procedures. Methods From December 2003 to January 2006, 42 patients with thoracolumbar fractures received the anterior surgical procedures to decompress and reconstruct the spinal vertebral structure with the artificial vertebral body of the nHA/PA66 composite. Among the patients, there were 28 males and 14 females, aged 1767 years, averaged 43.6 years. The thoracolumbar fractures developed at T12 in 5 patients, at L1 in 17, at L2 in 14, and at L3 in 6. The height of the anterior border of thevertebral body amounted to 29%-47% of the vertebral body height, averaged 40.6%.The Cobb angle on the sagittal plane was 2138° averaged 27.6°. According tothe Frankel grading scale, the injuries to the nerves were as the following: Grade A in 7 patients, Grade B in 19, Grade C in 8, Grade D in 6, and Grade E in 2. Results All the 42 patients were followed up for 625 months. Among the patients, 36 were reconstructed almost based on the normal anatomic structure, and 6 were well reconstructed. The mean height of the anterior border of the vertebralbody was 40.6% of the vertebral body height before operation but 91.7% after operation. And the reconstructed height of the vertebra was maintained. The mean Cobb angle on the sagittal plane was 27.6°before operation but 13.4° after operation. All the patients had a recovery of the neurological function that had a 1grade or 2grade improvement except 7 patients who were still in Grade A and 2 patients who were in Grade D. The implant was fused 35 months after operation. No infection, nail break, bar/plate break or loosening of the internal fixation occurred. Conclusion The artificial vertebral body of the biomimetic nHA/PA66 composite can effectively restore the height and the structure of the vertebra, can be fused with the vertebral body to reconstruct the spinal structural stability effectively, and can be extensively used in the clinical practice.

Abstract Dual-blade plate is widely used in reconstruction of anterior stability of spine. Two hundred and ninety-eight cases were followed up since 1984. Among them, 181 cases were fractureof thoracolumbar spine; 63 cases were tuberculosis of thoracolumbar spine; 43 cases were tumor of thoracolumbar spine; 5 cases were spondylisthesis of lumbar spine; 2 cases were ankylosing spondylitis accompanied with gibbosity; 2 cases were adolescent vertebral epiphysis; I case was hemivertebra; I case was dysplasia of the first lumbar vertebra acompanied with gibbosity. Most cases were successful following operation, but in some cases, the results were unsuccessful, mainly due to the position of the dualblade plate in the vertebral body was not satisfactory. The mistakes most commonly occurred were one or two blades, or a part of the blade going into the intervertebral space, and less commonly seen was deviation of the dual -blade plate from itscorrect orientation or a little side-bent of the blade. Split of the vertebra and fall off of the dual-blade plate were happened in few cases. The causeswere analyzed and ways of prevention were provided in this article.
Objective To explore the short-term therapeutic effect of mini-incision common vertebral pedicle screw internal fixation on thoracoclumbar fractures without neurological injury. Methods The data of 61 patients with thoracolumbar fractures without neurological injury treated with mini-incision common vertebral pedicle screw internal fixation (the mini-incision group, n=32) or percutaneous pedicle screw fixation (the percutaneous group, n=29) from February 2014 to January 2016 was retrospectively collected and analyzed. Total incision length, operation time, blood loss, fluoroscopy times, postoperative bed rest time, hospitalization costs, Visual Analogue Scale (VAS) score, Oswestry Disability Index (ODI), vertebral Cobb angle of correction, and accuracy rate of screw placement were compared between the two groups. Results All the patients were followed up for 6 to 24 months with a mean of 13.4 months. There were no complications such as incision infection and neurovascular injury except for 2 screws breakage in one patient in the percutaneous group. In the mini-incision group, the average total incision length was longer than that in the percutaneous group [(7.33±0.53) vs. (6.38±0.44) cm], while the average operation time was shorter than that in the percutaneous group [(62.66±4.75) vs. (72.93±5.09) minutes]; the differences were statistically significant (P<0.001). In the mini-incision group, the average frequency of fluoroscopy was fewer [(5.63±0.61)vs. (19.07±1.60) times] and the average hospitalization costs was lower [(23.3±1.5) thousand yuan vs. (39.5±1.6) thousand yuan] than those in the than that in the percutaneous group; the differences were statistically significant (P<0.001). No significant difference was found in blood loss, postoperative bed rest time, VAS score, ODI, vertebral Cobb angle of correction, and accuracy rate of screw placement between the two groups (P>0.05). Conclusions Mini-incision common vertebral pedicle screw internal fixation for thoracoclumbar fractures without neurological injury has the advantages of short operation time, less fluoroscopy times, low hospitalization costs and high fixation strength. It may obtain a good short-term effectiveness.

Methods From October 2008 to October 2010, type Ⅲ Acrylic resin bone cement and the system of vertebroplasty were used in percutaneous kyphoplasty (PKP) to treat 40 patients. There were 5 males and 35 females with an average of 65 years old (53-84 years). There were 37 older patients with osteoporotic vertebral compression fracture, 2 cases of vertebral tumor and one hemangioma. Visual analogue scale (VAS) was used to evaluate the pain before and after the operation. The complications in and after the operation were also recorded. Results Before discharge, posterior-anterior and lateral X-ray films were taken to evaluate the distribution of bone cement. Three patients showed a little bone cement leakage from the vertebral body, but no clinical symptoms were found. All patients were followed for 1 to 12 months with an average of 8 months. Pain in the back decreased obviously or disappeared, and the qualities of daily life were improved greatly. The score of VAS was (8.30±0.48) before the operation, and (3.11±0.41), (2.50±0.36), and (2.50±0.36) 3 days, 1 month after the operation, and during the last follow-up, respectively. Significant differences were found between the VAS score before and after operation (Plt;0.05). Conclusions Good results can be expected when bone cement is used in percutaneous kyphoplasty. Solidified bone cement can effectively support and stablize the spinal column.
Objective To evaluate the effect of self-designed antirotation reduction internal fixator(ARRIF) on treating different spine segment fracture.Methods From August 1999 to March 2003, 76 patients(48 males and 28 females, aged from 22 to 59 with an average of 34.1) with thoracolumbar fracture were operatively treated by ARRIF. The follow-up period ranged from 6 to 21 months(15 months in average). Classification according to injury segment: flexion compression racture 27 cases, burst fracture 42 cases, flexion distraction injury 3 cases, flexion revolving type fracture dislocation 2 cases, shear force type dislocation 2 cases. Classification according Frankel’s grade:A grade 16 cases, B grade 15 cases, C grade 27 cases, D grade 10 cases, E grade 8 cases.Operation duration, volume of bleeding, incidence postoperation complication and effect of reduction fixation were observed.

The nerve function showed one Frankel’s grade improvement after operation were as follows:A grade 8 cases(50%), B grade 11 cases (73.3%), C grade20 cases(74.1%), D grade 3 cases (30%); 2 Frankel’s E cases have no nerve function changes.The nerve function damage have no aggravation in all the patients,the postoperation Cobb’s angle was averagely corrected 22°. The horizontal displacement of dislocation vertebrae was averagely corrected 28% in sagittal plane, the statistical analysis had significant variance(Plt;0.01).ARRIF had no complications of the breakage of screws and rods. Conclusion ARRIF proves to be a valid internal fixator in reducing and fixing different thoracic lumbar segment spine fracture.
ObjectiveTo compare the clinical results of throacolumbar fractures treated through Wiltse paraspinal approach and conventional posterior approach. MethodsSeventy-six cases of single segmental thoracolumbar fractures (Type A) were treated by posterior reduction and pedicle screw instrumentation from January 2011 to January 2013. Thirty-five cases were treated through Wiltse paraspinal approach (group A), including 27 males and 8 females with an average age of 39.7 years. Forty-one cases were treated through conventional posterior approach (group B), including 30 males and 11 females with an average age of 41.6 years. The data including incision length, operation time, intraoperative blood loss, postoperative volume of drainage, the anterior vertebral height, Cobb angle and complications were compared between the two groups. ResultsAll operations were finished successfully. The incision length, operation time, intraoperative blood loss and postoperative volume of drainage were (8.3±1.9) cm, (74.0±21.9) min, (125.0 ±46.7) mL, and (51.0±42.6) mL respectively in group A, and (10.7±2.8) cm, (97.0±18.2) min, (245.0±56.1) mL, and (190.0±72.3) mL in group B respectively. There was significant difference between the two groups (P<0.05). The restoration of anterior vertebral height and the correction of Cobb angle were well maintained in both groups. The difference was statistically significant before and after treatment (P<0.05), but there was no significant difference between the two groups (P>0.05). There was no difference in the complication rate between the two groups (P>0.05). ConclusionCompared with conventional posterior approach, Wiltse paraspinal approach has the advantage of shorter operation time, less trauma and blood loss. It is a better option for the treatment of throacolumbar fractures.
