摘要:

背景:腰椎后外侧植骨融合中需要进行植骨,但骨量常不够,需再取患者部分自体髂骨补充。
目的:探讨纳米晶胶原基骨材料在腰椎后外侧植骨融合中的应用安全性及效果。
方法:回顾性分析四川省眉山骨科医院2013年2月至2014年2月收治的52例腰椎退行性疾病患者的临床资料,均实施腰椎后外侧植骨融合治疗,术中所使用的植骨材料为患者自体骨颗粒混合纳米晶胶原基骨材料。
结果与结论:52例患者中,内固定后伤口一期愈合的有51例,患者局部皮肤均未出现皮温上升以及红肿、疼痛、流液等现象。患者内固定后功能和疼痛症状均得到不同程度的改善,对患者的内固定后植骨融合情况进行分析,可得内固定后3个月完全融合率达13%,内固定后6个月达54%,内固定后12个月达84%,且未出现假关节,随访12个月,所有患者均未出现螺钉松动或者移位等现象,对固定节段相临椎体情况进行检查,均未出现滑脱或者移位等情况。表明在腰椎后外侧植骨融合中应用纳米晶胶原基骨材料可以获得良好的效果,材料具有生物相容性及一定的安全性。

Abstract:

BACKGROUND: Bone grafting is often needed in posterolateral lumbar spinal fusion, but bone mass is often not enough to finish this operation. Part of the autologous iliac bones from patients are needed to take as supplement.

OBJECTIVE: To investigate the safety and effectiveness of application of nano-hydroxyapatite/collagen/ poly(L-lactide) for posterolateral lumbar spine fusion.

METHODS: The clinical data of 52 patients with lumbar degenerative disease who had received the treatment in Meishan Orthopedics Hospital of Sichuan Province, China during February 2013 to February 2014 were retrospectively analyzed. The patients all received posterolateral lumbar spine fusion with bone grafts made of autologous iliac bone particles and nano-hydroxyapatite/collagen/poly(L-lactide).

RESULTS AND CONCLUSION: Among the 52 patients, wound healing by primary intention occurred in 51 patients, increased skin temperature, skin swelling, pains and fluid leaking were not observed. The lumbar spine function and pain symptoms of patients all improved to different degrees after internal fixation, The posterolateral lumbar spine fusion rate was 13%, 54% and 84% at 3, 6 and 12 months after internal fixation respectively, and there was no pseudarthrosis. During the 12 months of follow-up period, no screw loose or displacement , adjacent segment slippage or displacement were observed in any patient. These results suggest that the application of nano-hydroxyapatite/collagen/poly(L-lactide) for posterolateral lumbar spine fusion can achieve good results. The nano-hydroxyapatite/collagen/poly(L-lactide) bone graft material is highly biocompatible and safe.
