摘要:

文题释义:
股骨转子间骨折复位质量:根据张世民教授提出的股骨转子间骨折复位质量评分进行评估。对线:①X射线正位片:正常或轻度外翻的颈干角;②X射线侧位片:小于20°的成角。对位:①X射线正位片:中性或正性内侧皮质支撑;②X射线侧位片:平齐的前侧皮质接触。满足1个记为1分,复位质量根据得分分为优(4分)、中(3/2分)、差(1/0分)3个等级。

背景:对于复杂的股骨转子间骨折复位缺乏有效的术前规划方法,导致手术时间延长,手术难度增加。同时数字骨科三维可视化技术在股骨转子间骨折手术中应用的优势缺乏临床验证。
目的:通过数字骨科三维可视化技术明确复杂股骨转子间骨折的移位情况,实现术前模拟复位固定,从而为术中复杂股骨转子间骨折复位以及固定提供思路与方法。
方法:选择2019年1月至2020年1月上海交通大学医学院附属仁济医院收治的复杂股骨转子间骨折患者(AO分型A2与A3型),按照患者入院的先后顺序分为三维重建模拟组与对照组。按照就诊入院程序,所有患者均实施患侧髋关节正侧位X射线平片检查、患侧髋关节CT扫描检查。三维重建模拟组患者通过Mimics 17.0软件实现三维重建,然后对粉碎的骨折块进行模拟复位内固定;对照组仅根据术前影像学检查进行内固定治疗。收集有关数据比较两组患者在手术时间、术中出血量、髋关节复位质量评分以及随访时髋关节功能等方面的差异。
结果与结论:①与对照组相比,三维重建模拟组患者手术时间明显缩短,术中出血量明显减少,两组之间差异有显著性意义(P < 0.05);②骨折复位质量评分方面,三维重建模拟组患者术后复位质量评分优良率96%显著高于对照组82%,差异有显著性意义(P < 0.05);③三维重建模拟组患者术后6个月髋关节功能评分为(95.7±5.8)分,显著高于对照组(82.9±10.2)分,差异有显著性意义(P < 0.05);④结果证实,对于复杂股骨转子间骨折术前通过Mimics软件进行三维重建模拟复位有助于全面了解骨折移位情况,详细指导术中骨折复位与内固定物的选择,从而缩短手术时间,减少术中出血量,改善治疗效果。

Abstract: BACKGROUND: For complex intertrochanteric fractures, there is lack of effective preoperative planning, which lead to prolonged operation time and increased difficulty. At the same time, the application of digital orthopedics three-dimensional (3D) visualization technology in the operation of intertrochanteric fracture lacks clinical application verification.
OBJECTIVE: 3D visualization technology for digital orthopedics can be used to clarify the displacement of complex intertrochanteric fractures and realize preoperative simulated reduction and fixation, thus providing ideas and methods for intraoperative reduction and fixation of complex intertrochanteric fractures.
METHODS: Patients with complex intertrochanteric fractures (AO typing: A2 and A3) admitted to Renji Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from January 2019 to January 2020 were selected and randomly divided into Mimics 3D reconstruction simulation reduction group and control group according to the order of admission. According to medical procedures, all the patients were implemented with plain X-ray examination of the affected hip and CT scanning of the affected hip. Patients in the Mimics 3D reconstruction simulation reduction group achieved 3D reconstruction through Mimics 17.0 software, and then the shattered fracture blocks were simulated reduction and fixation. Patients in the control group were treated with internal fixation only according to preoperative imaging examination. Data were collected to compare the differences between the two groups in terms of operation time, intraoperative blood loss, hip reduction quality score, and hip function during follow-up. 
RESULTS AND CONCLUSION: (1) The operation time was significantly shorter in the Mimics 3D reconstruction simulation reduction group than that in the control group, and intraoperative blood loss was significantly reduced in the Mimics 3D reconstruction simulation reduction group compared with the control group, and the difference between the two groups was statistically significant (P < 0.05). (2) The excellent and good rate of hip reduction quality score was significantly higher in the Mimics 3D reconstruction simulation reduction group (96%) than that in the control group (82%) (P < 0.05). (3) The hip function score was significantly higher in the Mimics 3D reconstruction simulation reduction group (95.7±5.8) points than that in the control group (82.9±10.2) points 6 months after surgery (P < 0.05). (4) The results confirmed that for complex femoral intertrochanteric fractures, preoperative 3D reconstruction simulations by Mimics software reset can help to get a comprehensive understanding of fracture displacement, detailed guide the choice of intraoperative fracture reduction and internal fixation, help to shorten the operation time, lessen intraoperative blood loss, and improve the curative effect of intertrochanteric fracture.

Key words: intertrochanteric fracture, three-dimensional visualization, simulated reduction, reduction quality, hip function, internal fixation
