摘要:

文题释义:

纳米羟基磷灰石/聚酰胺66支撑棒:由纳米羟基磷灰石晶体颗粒均匀分散在聚酰胺66中组成,羟基磷灰石是一种活性生物陶瓷材料,为人和动物骨骼、牙齿的主要无机成分,在骨代谢过程中作为钙盐沉积的支架,可诱导新骨形成;聚酰胺是一种与胶原蛋白结构相似的有机高分子材料,具有加工简单、可塑性强的特点,二者复合而成的生物材料具有良好的生物相容性和生物安全性,可用于修复骨缺损,促进骨生长。

脱钙骨基质:是经一系列化学方法去除同种异体骨中的钙和脂肪,降低免疫原性,保留骨形态发生蛋白等成骨因子,具有良好的骨传导、骨诱导及促进成骨能力。脱钙骨基质特有的多孔隙结构适宜新骨生长替代,并使骨形态发生蛋白可以持久稳定地缓慢释放并长期发挥作用,其内保留的Ca2+可作为新生骨再钙化的核心,为磷酸钙沉积提供帮助。

 

摘要

背景:对于股骨头坏死Ⅲ期患者是否进行保头手术治疗,保头手术后临床效果如何,一直存在争议。

目的:分析纳米羟基磷灰石/聚酰胺66支撑棒结合同种异体骨治疗ARCOⅢ股骨头坏死的临床疗效。

方法:选择20173月至20189月航空总医院收治的股骨头坏死患者36例,其中男32例,女4例,年龄16-58岁,双侧坏死3例,单侧坏死33例,按ARCO分期中塌陷程度ⅢA35髋、ⅢB3髋、ⅢC1髋,均接受纳米羟基磷灰石/聚酰胺66支撑棒结合同种异体骨植入治疗。术后进行随访,采用Harris髋关节评分评价髋关节功能,利用X射线评估股骨头塌陷程度,CT检测评估坏死区成骨情况。研究获得航空总医院伦理委员会批准(伦理编号:HK2019-01-04)

结果与结论:36例患者获得(19.28±6.51)个月随访,末次随访时4个股骨头保头失败行全髋关节置换术,保头成功率为89.7%(35/39);②Harris髋关节评分显示,36例患者末次随访的髋关节功能优良率明显高于术前(71.8%17.5%P=0.000);③末次随访CT图像显示,术前ⅢA35髋中26髋可见明显成骨迹象;术前ARCOB3髋均未见明显成骨迹象;术前ARCOC1髋未见成骨;④末次随访X射线片显示,术前ARCOA35髋中5髋有进展,其中3髋进展到ⅢB期、2髋进展到Ⅳ期,剩余30髋病情稳定无进展;术前ARCOB3髋均有进展,其中2髋进展到ⅢC期,1髋进展到Ⅳ期;术前ARCOC1髋进展到Ⅳ期;⑤结果表明,纳米羟基磷灰石/聚酰胺66支撑棒结合同种异体骨治疗ARCOⅢ股骨头坏死具有较好的疗效。

Abstract:

BACKGROUND: It remains controversial whether patients with ARCO stage III osteonecrosis of the femoral head should be treated with femoreal head preserving surgery, and what the clinical efficacy of femoreal head preserving surgery is.

OBJECTIVE: To investigate the clinical efficacy of nano-hydroxyapatite/polyamide 66 support rod combined with bone allograft in the treatment of ARCO stage III osteonecrosis of the femoral head

METHODS: From March 2017 to September 2018, 36 patients (32 male and 4 female, 16-58 years old) with ARCO state III osteonecrosis of the femoral head who received treatment in Aviation General Hospital were included in this study. Among these patients, three had bilateral osteonecrosis of the femoral head and 33 had unilateral osteonecrosis of the femoral head. According to ARCO classification, 35 hips fell into stage IIIA, 3 hips in stage IIIB, and 1 hip in stage IIIC. All included paitents underwent nano-hydroxyapatite/polyamide 66 support rod combined with bone allograft. Postoperative follow up was performed. Hip joint function was evaluated using Harris hip score. The degree of collapse of the femoral head was evaluated using X-ray imaging. The osteogenesis in the necrotic area was determined by CT scans. This study was approved by Aviation General Hospital Ethics Committee (Ethics code: HK2019-01-04).

RESULTS AND CONCLUSION: (1) Thirty-six patients were followed up for (19.28±6.51) months. At the last follow-up, 4 hips ultimately underwent total hip arthroplasty with the success rate of 89.7%(35/39). (2) Harris hip score revealed that at the last follow-up, the excellent and good rate of hip function was significantly higher than that before surgery (71.8%,17.5%, P=0.000). (3) Last follow-up CT scans revealed obvious osteogenesis was observed in 26 of 35 hips at ARCO stage IIIA and it was observed in neither 3 hips at ARCO stage IIIB nor in 1 hip at ARCO stage IIIC. (4) At the last follow-up, X-ray showed that there was progress in 5 of the 35 hips (IIIA), 3 of which progressed to ARCO stage IIIB, 2 to ARCO stage IV, and the remaining 30 hips were stable without progression; three hips in ARCO stage IIIB progressed, including 2 progressed to ARCO stage IIIC and 1 to ARCO stage IV; 1 hip in ARCOIIIC stage progressed to ARCO stage IV. The results suggest that nano-hydroxyapatite/polyamide 66 support rod combined with bone allograft has a good effect on the treatment of ARCO stage III osteonecrosis of the femoral head.
