摘要:

文题释义:
3D 打印技术:是一种利用计算机辅助设计、数控技术、三维 CT 技术等快速成型技术,将数据立体化建模,并运用粉末状的金属或塑料等可黏合材料逐层融合叠加,最终打印出三维实物模型的技术。
髋关节置换:又称作人工髋关节置换,是将人工假体(包含股骨部分和髋臼部分)选择性使用骨水泥和螺钉固定在正常的骨质上,以取代病变的关节,重建患者髋关节的正常功能的手术。

背景:全髋关节置换手术量逐年增加,生物型假体表面处理方法较多,假体生存率及临床效果成为医患共同的关注点。 
目的:对比分析3D-精准构建臼杯和Pinnacle臼杯行全髋关节置换后的短期随访结果,研究3D打印钛合金骨小梁臼杯假体的稳定性。 
方法:回顾性分析宁夏回族自治区人民医院关节外科2016年1月至2019年12月行全髋关节置换患者96例98髋的病历资料,根据假体选择不同分为2组,其中观察组69髋假体采用3D钛合金骨小梁金属臼杯系统(ACT臼杯),对照组29髋假体采用Pinnacle臼杯系统。分别进行术后短期随访,通过目测类比疼痛评分、人工关节被遗忘评分、髋关节功能Harris评分、影像学评估进行临床疗效分析。
结果与结论:①两组术后1周目测类比评分、髋关节Harris评分相比差异有显著性意义(P < 0.05);两组术后1,6,12个月目测类比评分、髋关节Harris评分相比差异无显著性意义(P > 0.05);两组术后6,12个月人工关节被遗忘评分相比差异无显著性意义(P > 0.05);②术后12个月时,两组目测类比评分、髋关节Harris评分与术前相比均有显著改善(P < 0.05);③两组患者在术后随访期间,髋关节X射线片上臼杯周围Ⅰ、Ⅱ、Ⅲ区均未见放射透亮线存在,所有臼杯位置满意,未见明显移位征象,均达到稳定固定,臼杯与骨界面之间骨长入良好;④提示3D打印钛合金骨小梁金属臼杯初始稳定性较好,假体与骨界面之间骨长入良好,短期临床效果满意,长期效果需进一步随访。

Abstract: BACKGROUND: The number of total hip arthroplasty is increasing year by year. There are many surface treatment methods of biological prosthesis. The survival rate and clinical effect of prosthesis have become the common concern of doctors and patients.
OBJECTIVE: To compare and analyze the short-term follow-up results of 3D-accurate constructive technology socket cups and Pinnacle socket cups after total hip arthroplasty to investigate the stability of 3D-printed titanium alloy bone trabecular socket cup prostheses. 
METHODS: Medical records of 96 patients (98 hips) who underwent total hip arthroplasty from January 2016 to December 2019 in the Department of Joint Surgery, People’s Hospital of Ningxia Hui Autonomous Region were retrospectively analyzed. According to the choice of prosthesis, they were divided into two groups. Among them, 69 hips in the observation group used the 3D-printed titanium alloy bone trabecular socket cup (accurate constructive technology cup), and 29 hips in the control group used the Pinnacle cup. Short-term postoperative follow-up was performed by visual analogue scale pain score, forgotten joint score, Harris hip function score, and imaging assessment for clinical efficacy analysis. 
RESULTS AND CONCLUSION: (1) There were significant differences in the visual analogue scale score and hip Harris score between the two groups at 1 week after operation (P < 0.05). There was no significant difference in the visual analogue scale score and hip Harris score between the two groups at 1, 6, and 12 months after operation (P > 0.05). There was no significant difference in the forgotten joint score between the two groups at 6 and 12 months after operation (P > 0.05). (2) At 12 months after operation, the visual analogue scale score and hip Harris score in both groups were significantly improved compared with those before operation (P < 0.05). (3) During the postoperative follow-up of the two groups, no radiolucent lines were found around the acetabular cup in the X-ray films of the hip joint. All the cups were in satisfactory position, and no obvious signs of displacement were found. All of them achieved stable fixation, and the bone ingrowth between the cup and the bone interface was good. (4) In conclusion, the 3D-printed titanium trabecular metal socket cups had better short-time initial stability, good bone ingrowth between the prosthesis and bone interface, and satisfactory short-term clinical results; long-term results require further follow-up.
