| 【Abstract】 Objectives： To evaluate the effect of short-segment transpedicular fixation combined with vertebroplasty for thoracolumbar burst fractures in patients with osteoporosis. Methods: The clinical data of thoracolumbar burst fractures of 86 patients from January 2008 to March 2012 were analyzed retrospectively. There were 32 cases accompanied by osteoporosis including 14 males and 18 females with a mean age of 64.5(range, from 56 to 78 years old). The mechanisms of injuries were fall in 14 cases, traffic accident in 9 cases, high falling in 5 cases and heavy pound injury in 4 cases. The involved vertebrae included T11(3 cases), T12(10 cases), L1(15 cases) and L2(4 cases). Fractures were reduced with pedicle screw system followed by vertebroplasty. VAS and SF-36 scoring systems were used to evaluate the patients′ pain and life quality. The height recovery and kyphotic correction of fracture level were measured by X-ray. Results: All patients underwent surgery safely without severe complications occurred. The average follow-up time was 16.5 months(range, 12-36 months). There was significant difference(P<0.05) in VAS score at final follow-up(2.17±1.81) and post-operation(2.43±1.81) compared with pre-operation(7.67±2.25), respectively. And also there was significant difference(P<0.05) in SF-36 score between final follow-up(123.5±22.3) and post-operation(95.7±17.5). The Cobb angle recovered to 5.2°±1.2° of post-operation and 6.0°±2.3° of final follow-up, with a loss of 0.8°±1.5°. The vertebra height improved to (95.3±2.9)% of post-operation and (91.4±3.7)% of final follow-up, with a loss of(4.0±2.5)%. The asymptomatic bone cement intravenous leakage occurred in 3 patients. There was no breakage of internal fixations. Conclusions: Short-segment transpedicular fixation combined with vertebroplasty is a safe and effective management due to its less loss of correction and instrument failure. |
