摘要(Abstract):

目的:观察3种植骨方式对腰椎内固定术疗效的影响。方法:271例行腰椎植骨融合内固定术的腰椎疾病患者,根据植骨方式分为后外侧植骨组84例、椎间植骨组96例、360°植骨91例,所有患者于术后2、3、6月、1年及2年常规行X线摄片检查,比较3种术式的有效病例;比较术后2年,3种术式的失效例数及比例。结果:术后2月和3月时,3种植骨术式的有效率高达95%以上,两两比较,差异无统计学意义(P>0.05);从术后6月开始,后外侧植骨的有效率低于椎间植骨和360°植骨,术后2年时后外侧植骨有效率<90%,而椎间植骨和360°植骨仍>95%,差异有统计学意义(P<0.05);椎间植骨与360°植骨疗效比较,差异无统计学意义(P>0.05);术后2年时,后外侧植骨9例、椎间植骨3例及360°植骨2例患者发生内固定发生钉棒系统松动、断裂,失效率分别为10.07%、3.1%级2.2%,差异有统计学意义(P<0.05)。结论:椎间植骨术及360°植骨术的腰椎内固定疗效优于后外侧植骨。
Objective: To investigate the effect of three ways of bone graft for lumbar internal fixation. Methods: 271 patients with lumbar interbody fusion and internal fixation were divided into three groups according to mode of bone graft,84 cases in group posterior lateral bone graft,96 cases in bone graft intervertebral and 91 cases in 360 degree bone graft. The patients were examined with conventional radiography in second months,third months,sixth months,the first year and the second year. To compare the effective cases of three different bone graft methods and to compare the number and proportion of failure cases in second year of surgery. Results: The differences of the effective rate of the 3implants was more than 95% at second and third months after operation,there was no statistical significance( P > 0. 05). After sixth months,the effective rate of the posterior lateral bone graft was lower than that of the bone graft intervertebral and 360 degree bone graft. At second years after operation,the efficiency of the posterior lateral bone graft was less than 90%,while the intervertebral bone graft and the 360 degree bone graft were still higher than 95%,the difference was statistically significant( P< 0. 05). There was no significant difference in the curative effect between the bone graft intervertebral and the 360 degrees bone graft( P > 0. 05). Loosening and fracture occurred in the spinal fixation system were to be found 9 cases of posterior lateral bone graft,3 cases of intervertebral bone graft and360 degrees of bone graft were 2 cases. Loss of efficiency was 10. 7%,3. 1%,2. 2%,the differencewas statistically significant( P < 0. 05). Conclusion: The therapeutic effect of internal fixation with intervertebral bone grafting and 360 degree bone grafting is better than that of posterior lateral bone graft.
