[Show abstract][Hide abstract] ABSTRACT: To evaluate the efficacy of posterior instrumentation plus vertebroplasty and posterolateral fusion using calcium sulfate for thoracolumbar burst fractures without neurologic deficits.
Between July 2005 and January 2008, a total of 45 patients who had been diagnosed as having thoracolumbar burst fractures without neurologic deficits were treated with pedicle screw instrumentation plus vertebroplasty using calcium sulfate in our unit. The Cobb angles and loss rates of anterior-middle columns height at different time intervals were measured on lateral radiographs, and the preoperative and postoperative functional outcomes were evaluated using the Visual Analogue Scale (VAS) and Oswestry Disability Index (ODI).
The Cobb angles and loss rates of anterior-middle columns height postoperatively period were restored significantly compared with those noted preoperatively. The angles and heights were well maintained for at least two years using this technique. The mean postoperative VAS (back pain) score was 2.1 ± 0.8, which was significantly better (P < 0.001) than the mean preoperative VAS score 7.9 ± 1.1. The average preoperative ODI was 66.6 ± 8.1% and this had improved significantly to 15.5 ± 4.5% by the latest follow-up (P < 0.001). No instrumentation failure was detected in this study. The calcium sulfate had been absorbed completely by 3-6 months postoperatively.
Pedicle screw instrumentation plus augmentation vertebroplasty with calcium sulfate is an economic, efficient and reliable technique for treating unstable thoracolumbar fractures without neurologic deficits.

[Show abstract][Hide abstract] ABSTRACT: To analyze retrospectively the clinical outcome of surgical management for upper cervical spine injury caused by trauma.
From January 2005 to March 2007, 16 patients with injury of upper cervical spine were treated by different management. There were 11 males and 5 females with an average age of 44 years ranging from 24 to 75. Of all, 5 cases were the odontoid fracture, 3 were atlas fracture, 5 were Hangman's fracture, 3 were atlanto-axial dislocation. MR imaging of cervical spine showed cervical cord compression and changes of T2 high signal in 5 cases. According to the injury mechanism, the imageological appearance, fracture classification, the methods of treatment were selected.
Seven patients received non-operative treatment and nine patients underwent operation. Sixteen patients were followed up for 7 to 34 months (means 10.5 months). All fractures were healing or bone graft fusion and no internal fixation was lossing. There were no injuries of vertebral artery, nerve root or spinal cord.
CT and MRI are required in the course of diagnosis for the traumatic injury of upper cervical spine. The optimal modus operandi should be choose to retain upper cervical spine, meanwhile, can reserve the cervical movement.
