摘要
目的观察胸腰椎爆裂骨折后路经伤椎置钉短节段固定治疗的近远期疗效。方法根据是否经伤椎置钉将70例胸腰椎爆裂骨折患者分为观察组(经伤椎置钉,40例)与对照组(伤椎不置钉,30例),术后随访12~24个月,比较2组近远期疗效。结果观察组平均手术时间、术中出血量显著大于对照组,差异有统计学意义(P<0.05);2组住院时间、并发症发生率比较差异无统计学意义(P>0.05);2组末次随访脊髓神经功能美国脊柱脊髓损伤学会(ASIA)分级较术前差异有统计学意义(P<0.05),但2组间比较差异无统计学意义(P>0.05)。2组术后1周、末次随访的椎体高度均较术前显著提高,终板角均显著减少,差异有统计学意义(P<0.05);观察组末次随访椎体高度、终板角分别为(27.8±3.6)mm、(7±3)°,较对照组的(23.1±2.6)mm、(10±4)°差异有统计学意义(P<0.05)。结论后路经伤椎固定与跨伤椎固定的近期疗效相仿,但能有效预防术后远期椎体高度丢失及后凸畸形复发。
Objective To observe the short-term and long-term effects of posterior trans-fraetured vertebra screw-setting short-segment fixation in treating thoracolumbar burst fractures. Methods We divided 70 patients with thoraeolumbar burst fraetures into the observation group （with trans-fraetured vertebra screw-setting, 40 eases） and the control group （without trans-pedicular screw-setting, 30 cases） according to whether the patients receiving trans-fraetured vertebra screw-setting. All patients were followed up for 12-24 months after operation. The short-term and long-term efficacy was compared between the two groups. Results The average operation time and intraoperative blood loss were significantly longer and more in the observation group than the control group（ P〈0.05） ,respeetively. There was no significant difference between the two groups in the length of hospital stay and the incidence rates of complications （ P〉0.05）. At the end of follow-up, the spinal nerve function ASIA grade showed statistically significant differenee, compared with that before operation （ P〈0.05）, but there was no significant difference between the two groups （ P〉0.05）. One week after the operation and at the end of follow-up, the vertebral heights were significantly increased while the end plate angles were significantly decreased （P〈0.05）. At the end of follow-up, the vertebral height and end plate angle showed statistically significant differenees between the observation group and the eontrol group[（27. 8±3. 6） mm and （7±3） degrees vs （23.1±2.6） mm and （10±4） degrees] （ P （0.05）. Conclusion The short-term efficacy of posterior trans-fraetured vertebra fixation and trans-fraetured vertebra fixation is similar. It can effectively prevent long-term vertebral height loss and recurrence of kyphosis.
