摘要 股骨头坏死存在众多病因学说,针对不同学说和疾病不同分期而有多种治疗方法。钽棒支撑技术是近年开始应用的一项针对股骨头坏死的微创手术治疗手段,治疗原理是在坏死股骨头髓芯减压基础上以多孔钽金属棒为股骨头及软骨下骨板提供安全而有效的力学支撑,并促进新生骨与血管的长入。此技术操作简单,在透视引导下准确定位髓芯钉道后逐步扩髓、测深、攻丝并植入合适规格的钽棒。基础试验研究表明,多孔钽棒植入物在结构和生理力学特性上十分接近天然骨组织,且组织相容性和安全性好。临床试验研究发现,钽棒支撑能改善早期无塌陷股骨头坏死患者的髋关节功能,并有效阻止坏死加重;对中晚期患者的治疗效果则尚不肯定。钽棒支撑为无塌陷早期股骨头坏死患者提供了一种新的治疗方法。
