摘要:

文题释义:

3D打印导航模板3D打印技术与计算机虚拟导航相结合的技术,依据CT或者MRI成像的三维模型,结合快速成型的3D打印技术将虚拟三维导航模板打印成实体用于设计手术方案或引导术中操作。

髓芯减压植骨:股骨头坏死非塌陷期常用的保髋术式之一,通过钻孔降低股骨头内的高压,改善静脉回流,促进毛细血管再生,同时通过减压通道对股骨头内坏死区域植入人工骨或自体骨,分散股骨头局部应力集中,避免股骨头进一步塌陷。

背景:髓芯减压植骨是治疗ARCOⅡ期非创伤性股骨头坏死的主要术式,但是存在定位不准确,坏死骨清除不彻底或过多的风险。

目的观察3D打印导航模板辅助髓芯减压植骨治疗ARCO期非创伤性股骨头坏死的精确性和安全性。

方法 收集2017111月西安交通大学附属红会医院收治的80(96)ARCO期非创伤性股骨头坏死患者,将其随机分为2组,3D40(48)3D打印导航模板辅助髓芯减压植骨;对照组40(48)行传统髓芯减压植骨,即未使用导航模板。2组患者对治疗方案均知情同意,且得到医院伦理委员会批准。分别记录2组手术时间、术中透视次数、术中失血量,观察术后第361224个月X射线片复查结果,评估股骨头存活率、髋关节Harris评分、疼痛目测类比评分等指标,进行疗效对比。

结果与结论:①3D组与对照组比较,手术时间由(132.57±14.86) min缩短至(82.63±10.31) min,术中透视次数由(16.80±2.15)次降低至(4.93±1.36)次,失血量由(143.23±17.98)mL降低至(75.64±16.23)mL,3D组在手术时间、透视次数、失血量方面均优于对照组(P < 0.05);②术后24个月影像学随访结果显示,3D组仅2例股骨头发生塌陷,但髋关节功能尚可,未行人工髋关节置换,股骨头存活率为96%;对照组中有9例股骨头发生塌陷,其中4例因髋关节活动受限行人工全髋置换,股骨头存活率为81%;3D组股骨头存活率高于对照组(P=0.024);③与对照组比较,3D组在Harris评分、目测类比评分方面均有所改善(P < 0.05);④提示将3D 打印导航模板应用于髓芯减压植骨治疗ARCOⅡ期非创伤性股骨头坏死,可减少手术时间、术中透视次数及出血量,提高术中定位的精确性和安全性。

Abstract:

BACKGROUND: Core decompression and bone grafting is the main postoperative method in the treatment of ARCO stage II non-invasive necrosis of the femoral head, but there are risks of inaccurate location, incomplete or excessive removal of necrotic bone.

OBJECTIVE: To observe the accuracy and safety of three-dimensional (3D) printed navigation template assisted core decompression and bone grafting in the treatment of ARCO stage II non-traumatic femoral head necrosis.

METHODS: Eighty patients (96 hips) of ARCO stage II non-traumatic femoral head necrosis were enrolled from January to November 2017 in Honghui Hospital Affiliated to Xi’an Jiaotong University. The patients were randomly divided into two groups. In the 3D group, 40 cases (48 hips) received 3D printed navigation template assisted core decompression and bone grafting. In the control group, 40 cases (48 hips) received core decompression and bone grafting (no navigation template). All patients signed the informed consent. This study was approved by the Hospital Ethics Committee. The operation time, intraoperative fluoroscopy, and intraoperative blood loss were recorded, and X-ray examination results at 3, 6, 12, and 24 months after operation were observed. The femoral head survival rate, hip Harris score, and pain visual analogue scale score were evaluated. The efficacy was compared.

RESULTS AND CONCLUSION: (1) Compared with the control group, the operation time was shortened from (132.57±14.86) minutes to (82.63±10.31) minutes; the number of intraoperative fluoroscopy was reduced from (16.80±2.15) times to (4.93±1.36) times; blood loss was reduced from (143.23±17.98) mL to (75.64±16.23) mL in the 3D group. Operation time, number of fluoroscopy, and blood loss were superior in the 3D group than in the control group (P < 0.05). (2) The 24-month follow-up of imaging showed that only 2 cases of the femoral head collapsed in the 3D group, but the hip joint function was acceptable. There was no artificial hip arthroplasty and the femoral head survival rate was 96%. In the control group, femoral head collapsed in 9 cases. Four of them had total hip arthroplasty due to limited hip joint activity, and the femoral head survival rate was 81%. The survival rate of the femoral head in the 3D group was higher than that in the control group (P=0.024). (3) Compared with the control group, Harris score and visual analogue scale score were improved in the 3D group (P < 0.05). (4) Applying 3D printed navigation template to core decompression and bone grafting for ARCO stage II non-traumatic femoral head necrosis can reduce the operation time, intraoperative fluoroscopy and blood loss, and improve the accuracy and safety of intraoperative positioning. 

Key words: non-traumatic femoral head necrosis, 3D printed navigation template, core decompression, bone grafting, intraoperative fluoroscopy
