摘要:

文题释义:
3D打印导板:根据术中需要而采用计算机软件辅助设计、3D打印制备的一种个性化手术器械,用于术中准确定位,辅助术中精确建立孔道、截面、空间距离、相互成角关系及其他复杂空间结构等。
新型股骨颈内固定系统:为“钉中钉”设计,既能微创置入,又可以提供稳定的抗旋力,而且很少出现螺钉切割、退钉等现象,使患者术后早期下地部分负重,提高了生活质量,为青年股骨颈骨折内固定治疗提供了新的治疗手段。

背景:对于中青年股骨颈骨折患者,内固定治疗往往是首选手术方式。但是传统内固定治疗存在内固定失败、骨折不愈合及股骨头坏死等风险,因此选择一种合适的股骨颈骨折内固定系统具有重要的临床意义。
目的:探讨3D打印导板辅助新型股骨颈内固定系统置入治疗中青年股骨颈骨折的应用价值。
方法:选取2020-2021年在苏州大学附属张家港医院骨科接受新型股骨颈内固定系统手术的24例中青年股骨颈骨折患者为研究对象,根据手术方法分为2组,每组12例。试验组在术前设计制作3D打印导板,辅助新型股骨颈内固定系统开展内固定手术;对照组采用徒手新型股骨颈内固定系统开展内固定手术。比较两组患者一般资料、手术情况、随访结果(骨折愈合时间,术前、术后1周、术后6个月目测类比评分及Harris评分)及并发症发生情况。
结果与结论:①24例患者均获得6个月以上的随访;②试验组手术时间、透视次数和出血量均少于对照组,差异有显著性意义(P < 0.05);③两组末次随访时均获得骨性愈合,均未出现内固定失效及股骨头坏死等并发症;④两组患者术后髋部疼痛均显著缓解;试验组术后1周及术后6个月目测类比评分低于对照组,但差异无显著性意义(P > 0.05);⑤两组患者术后髋关节功能改善显著,试验组术后1周、术后6个月Harris评分优于对照组,但差异无显著性意义(P > 0.05);⑥提示新型股骨颈内固定系统治疗中青年股骨颈骨折取得了良好的手术效果,可以早期下地部分负重,3D打印导板辅助新型股骨颈内固定系统置入能减少手术时间、透视次数及出血量。

Abstract: BACKGROUND: Internal fixation is often the first choice for patients in middle-aged and young adults. However, there are some risks in traditional internal fixation treatment, such as failure of internal fixation, nonunion of fracture and avascular necrosis of the femoral head. Therefore, it is of great clinical significance to choose a suitable internal fixation system for femoral neck fracture.  
OBJECTIVE: To explore the application value of 3D printed guide plate assisted new femoral neck system in the treatment of femoral neck fracture in middle-aged and young adults.
METHODS:  Totally 24 patients of middle-aged and young adults with femoral neck fracture who underwent surgery with femoral neck system in the Department of Orthopedics, Zhangjiagang Hospital Affiliated to Soochow University from 2020 to 2021 were randomly divided into two groups (n=12 per group). The experimental group designed and made 3D printed guide plate to assist the femoral neck system internal fixation operation before operation, while the control group was treated with freehand new femoral neck system for internal fixation. The general data, operation and follow-up results (fracture healing time, visual analogue scale score and Harris score before operation, 1 week and 6 months after operation), and complications were compared between the two groups.  
RESULTS AND CONCLUSION: (1) All the 24 patients were followed up for more than 6 months. (2) The operation time, the times of fluoroscopy and the amount of intraoperative blood loss in the experimental group were significantly less than those in the control group (P < 0.05). (3) During the last follow-up, all patients in the experimental group and control group achieved bone healing. There were no complications such as internal fixation failure and avascular necrosis of the femoral head in the experimental group and control group. (4) The hip pain was significantly relieved in the two groups. The visual analogue scale score in the experimental group was lower than that in the control group at 1 week and 6 months after operation, and the difference was not statistically significant (P > 0.05). (5) The hip joint function of the two groups was significantly improved after operation. The Harris score of the experimental group was better than that of the control group at 1 week and 6 months after operation, and the difference was not statistically significant (P > 0.05). (6) The results show that the new femoral neck system has achieved a good surgical efficacy in the treatment of femoral neck fracture in middle-aged and young adults. Femoral neck system assisted by 3D printed guide plate can reduce the operation time and fluoroscopy times, and the amount of intraoperative blood loss.
