摘　　要：背景:脊柱融合过程中使用一定的骨移植材料可以达到促进骨融合、增强脊柱稳定性的效果。目的:探讨自体骨髓富集的间质干细胞复合羟基磷灰石磷酸三钙在脊柱融合中的应用效果。方法:回顾性分析64例行脊柱融合患者的临床资料,按照植骨融合材料的不同分为对照组(32例)和观察组(32例),分别予以自体髂骨移植和自体骨髓富集的间质干细胞复合羟基磷灰石磷酸三钙移植。治疗后随访12个月,对两组患者腰背疼痛、脊柱融合、伤椎复位情况等进行评估。结果与结论:治疗后两组患者LBOS评分、LBOS评分优良率、脊柱融合Lenke分级、Cobb角经比较差异无显著性意义(P>0.05)。两组患者均未出现感染和炎症表现,内固定物对皮肤无刺激现象。两组患者凝血功能、肾功能、炎性因子相关指标均处于正常水平,差异无显著性意义(P>0.05)。试验结果表明,自体骨髓富集的间质干细胞复合羟基磷灰石磷酸三钙应用于脊柱融合可以获得与自体髂骨移植基本相当的临床效果。BACKGROUND： The use of bone graft materials can promote bone fusion and enhance the stability of the spine during the spinal fusion. OBJECTIVE： To investigate the effect of autologous bone marrow mesenchymal stem cells with hydroxyapatite/ tricalcium phosphate in the spinal fusion. METHODS： A retrospective analysis of clinical data of 64 patients with spinal fusion was carried out, and these patients were divided into two groups（n=32 per group）： control group undergoing autogenous iliac bone grafting and observation group undergoing autologous bone marrow mesenchymal stem cells combined with hydroxyapatite/tricalcium phosphate. All patients were followed up for 12 months, and their recovery conditions about low back pain, spinal fusion and vertebral reset were assessed. RESULTS AND CONCLUSION： The low-back outcome scale scores and excellent rate, Lenke grading and Cobb angle had insignificant differences between the two groups after treatment（P〈0.05）. No infection, inflammation and skin irritation occurred in the two groups. The coagulation function, renal function and inflammatory factor levels were at normal levels in all the patients, and there was no difference between the two groups（P〉0.05）. These findings indicate that autologous bone marrow mesenchymal stem cells combined with hydroxyapatite/tricalcium phosphate can achieve clinical outcomes equivalent to the autologous iliac bone grafting.
