摘要
目的：探讨经伤椎椎弓根螺钉恢复椎体前缘高度及脊椎生理弯曲的可行性和科学性。方法：采用经伤椎椎弓根螺钉内固定术治疗胸腰椎爆裂骨折20例，其中单一节段18例、双节段1例、三节段1例；DRFS18例、PRSS2例；神经功能Frankle分级A级2例，B级1例，C级1例，D级8例，E级8例。观察术前术后伤椎前后缘高度比、后凸角及神经功能Frankle分级的变化。结果：20例均接受1-4a随访。术前术后伤椎前后缘高度比分别为45．2％±19．6％和94．6％±6．3％。19例后凸畸形矫正，至前凸8．3°±8．7°（-8°～30°）。术后神经功能Frankle分级A级1例、D级5例、E级14例。结论：经伤椎椎弓根螺钉撬拨可以使骨折块复位，更好地恢复伤椎前缘高度及脊柱生理弯曲，为神经功能恢复创造条件。
Objective： To investigate the practicability of a new method to treat the thoracolumbar burst fractures by the pedicle screw of the injured vertebrae. Methods ：20 patients with complete or incomplete neurological deficits as a result of the thoracolumbar or lumbar burst fractures were included in this study, including 18 cases with the single segment fracture and 1 case with double segment fractures and 1 case with three segment fractures. 18 cases were fixed with DRFS system, 2 cases with PRSS system. The ratio of vertebra body height and degrees of lordosis were recorded before and after operation, so did the neurological condition of the patients according to the Frankle system. Results ：20 cases were followed up 1 -4 years. The ratio of vertebra body height were 94.6% ± 6.3% （82.5%± 100% ） and the degrees of lordosis were 8.3°± 8.7° （ - 8°- 30° ） after operation. The neurological condition of the patients were recorded before and after operation accord- ing to the Frankie system, And during following up period, the neurological functions were obviously improved in the cases of the incomplete neurological deficit. Conclusions： The method that reduced and fixed through the pedicle of the injured vertebrae could achieve satisfactory results in clinical practice, the injured vertebral body height was recovered and the kyphosis was corrected and the lordosis were recovered. Neural canal decompression and stabilization of the thoracolumbar and lumbar burst fractures were performed. This technique had more than the classical posterior method, especially in the fracture -dislocation cases.
