摘要:

背景:计算机技术已经实现了从二维图像到三维图像的飞跃,加上与快速成型术的完美结合,使临床医师可以准确判断骨折部位和制定手术计划。术前骨折复位模拟明显提高了手术的安全性和手术的质量。
目的:评价计算机辅助在骨盆骨折诊断与治疗方面的临床价值。
方法:收集20例骨盆骨折患者,随机分成计算机辅助组和传统手术组。传统手术仅行骨盆X射线片和二维CT扫描,计算机辅助组提取CT原始数据,利用MIMICS软件进行三维重建,通过快速成型技术按照1∶1比例制作骨盆和钢板模型。术者及手术参与人员术前进行骨折复位仿真模拟训练,重建过程中记录手术时间和术中出血量,与传统手术进行比较。
结果与结论:重建过程中所见与术前制作的三维骨盆骨折模型非常相似,术前的演练使术中参与者配合更默契,操作更迅速,更精确。计算机辅助组患者均获得良好的骨折复位,术中钢板的折弯更伏贴骨质,钢钉的长度更合适,位置更佳。与传统手术相比较,计算机辅助手术术中出血量更少,手术时间更短,差异有显著性意义(P < 0.05)。计算机辅助临床手术具有创伤小、更精确的特点,对患者和医疗人员更加安全,它在骨科及其他科室手术中有着广阔的应用前景。

Abstract:

BACKGROUND: The rapid development of computer technology has realized the leap from two-dimensional image to three-dimensional image. With the perfect combination of the rapid prototyping technique, the clinician can accurately judge the fracture location and draw up a plan of operation. Preoperative fracture reduction and simulation obviously improve the safety and quality of the operation.
OBJECTIVE: To evaluate the clinical value of computer-aided technology in diagnosis and treatment of pelvic fracture.
METHODS: We collected 20 patients with pelvic fractures, who were randomly divided into the computer-aided group and the traditional surgery group. Traditional surgical method only needed X-ray and two-dimensional CT scanning of pelvis. Computer-aided group needed to extract original CT data, used MIMICS software for three-dimensional reconstruction. The models of pelvic and steel plate were made using rapid prototyping technique according to the proportion of 1:1. Performers and participants completed surgical simulation training before the operation. Time used in surgery and volume of blood loss during operation were recorded, and compared with the traditional surgery.
RESULTS AND CONCLUSION: What seen in the operation was very similar to what seen from the preoperative model of pelvic fracture. The preoperative practice made participants more tacit understanding, resulting in operating quicker and more accurate. All patients of computer-aided group got good fracture reduction, intraoperative steel plate bending more fitting for bone, the length of the steel nail was more appropriate, the location was better. Compared with traditional surgery, computer-assisted surgery had less blood loss, shorter operation time and more statistically significant difference (P < 0.05). Computer-aided clinical surgery has characteristics of small trauma, more accurate, more safety for patients and medical staffs, and has broad  application prospects in orthopedics and other departments.
