摘要:

背景:钛合金和不锈钢是两种较为常用的内固定植入材料,但两种材料的治疗效果和生物相容性存在一定的差异。
目的:分析钛合金和不锈钢内固定材料置入治疗脊柱结核的效果及生物相容性。
方法:纳入脊柱结核患者71例,其中男35例,女36例,年龄17-81岁,35例进行钛合金内固定材料置入治疗,36例进行不锈钢内固定材料置入治疗。随访12个月,分析两组脊柱后凸畸形角度变化、治疗效果、Frankel脊髓损伤分级及材料生物相容性。
结果与结论:两组治疗前的脊柱后凸畸形角度、Frankel脊髓损伤分级比较差异无显著性意义,两组治疗后末次随访的脊柱后凸畸形角度、Frankel脊髓损伤分级均较治疗前明显改善(P < 0.05),但两组间比较差异无显著性意义;钛合金内固定组治愈34例(97%),不锈钢内固定组治愈33例(92%),两组间治愈率比较差异无显著性意义。两种材料均具有良好的生物相容性,未发生感染等不良反应。表明在脊柱结核治疗过程中,置入钛合金或不锈钢内固定材料均能获得良好的效果,并具有良好的生物相容性。

Abstract:

BACKGROUND: Titanium alloy and stainless steel are two common internal fixation materials, but there are some difference in their therapeutic effects and biocompatibility.
OBJECTIVE: To explore the therapeutic effects and biocompatibility of titanium alloy and stainless steel internal fixation materials for the treatment of spinal tuberculosis.
METHODS: Seventy-one spinal tuberculosis patients, 35 males and 36 females, aged 17-81 were enrolled. Among them, 35 patients received titanium alloy internal fixation, and the 36 patients underwent stainless steel internal fixation. At the end of 12-month follow-up, Cobb angle changes, therapeutic effect and Frankel grade were analyzed in the two groups.
RESULTS AND CONCLUSION: Before treatment, there was no difference in the spinal kyphosis angle and Frankel grade between the two groups. At the last follow-up, the Frankel grade and Cobb angle were both improved in the two groups (P < 0.05), but there was still no difference between the two groups. The cure rate was 97% (n=34) in the titanium alloy group and 92% in the stainless steel group (n=33), and no significant difference was found between the two groups. These two kinds of internal fixation materials exhibited good biocompatibility, and no infection and other adverse reactions occurred. These findings indicate that both titanium alloy and stainless steel as internal fixation materials have good biocompatibility and therapeutic effects.
