目的：探讨应用计算机虚拟复位结合3D打印技术对髋臼手术进行术前规划，评估其应用价值及其疗效。
方法：回顾分析2011年3月至2014年3月采用手术内固定方式治疗的35例髋臼骨折患者，按术前是否应用计算机虚拟复位和3D打印技术分为数字组和对照组。数字组15例，男9例，女6例；年龄22~58岁，平均（39.4±8.8）岁；受伤至手术时间（8.8±2.0）d；按Letournel-Judet分型：双柱骨折4例，后壁骨折5例，T型骨折4例，后壁伴横行骨折2例。对照组20例，男12例，女8例；年龄19~59岁，平均（38.7±13.1）岁；受伤至手术时间（8.2±2.3）d；按Letournel-Judet分型：双柱骨折6例，后壁骨折8例，T型骨折3例，后壁伴横行骨折3例。比较两组患者的术中出血量、输血量、手术时间、骨折复位满意率和d'Aubigne Postal功能评定优良率，并进行统计分析。
结果：所有患者切口均Ⅰ期愈合，无切口感染情况发生；骨折均Ⅰ期愈合，无内固定断裂或松动。两组各有1例术后出现神经刺激症状。数字组1例在术后6个月发现股骨头坏死。常规组1例在术后8个月发现异位骨化。35例患者获得随访，时间13~28个月，平均17.6个月。数字组患者的术中出血量、输血量显著少于对照组患者，手术时间短于对照组患者，差异有统计学意义（P<0.05）。数字组和对照组骨折复位优良率分别92.9%（14/15）和85%（17/20），差异无统计学意义（P>0.05）。两组末次随访时d'Aubigne Postal功能评定优良率分别为86.7%（13/15）和80%（16/20），差异无统计学意义（P>0.05）。
结论：计算机虚拟复位结合3D打印技术可以减少髋臼骨折患者的手术时间、术中出血量和输血量，是一种切实有效的术前规划方式，值得推广。 |

Abstract:
Objective: To investigate the computer-assisted virtual reduction combined with 3D printing technique as preoperative planning and assess their therapeutic effects.
Methods: Thirty-five cases of acetabular fracture treated by internal fixation from March 2011 and March 2014 were retrospectively analyzed. All patients underwent operations with internal fixations implanted. The patients were divided into 2 groups according whether they used the computer-assisted virtual reduction combined with 3D printing technology. Fifteen patients in the digital group included 9 males and 6 females with a mean age of (39.4±8.8) years old ranging from 22 to 58 years old;time from injury to the operation was (8.8±2.0) days;for Letournel-Judet classification,4 cases were both column fracture,5 cases were posterior wall fracture,4 cases were T-fracture,2 cases were posterior wall with transverse fracture. Twenty cases in the control group included 12 males and 8 females with a mean age of (38.7±13.1) years old ranging from 19 to 59 years old;time from injury to the operation was(8.2±2.3) days;for Letournel-Judet classification,6 cases were both column fracture,8 cases were posterior wall fracture,3 cases were T-fracture,3 cases were posterior wall with transverse fracture. The volume of intraoperative blood loss and blood transfusion,operative time,satisfaction rate of fracture reduction and excellent and good rate of d'Aubigne Postal function evaluation were compared between the two groups and statistical analysis was conducted.
Results: All the incisions healed without infection occurred. All the fractures healed without breakage or loosening of plates and screws. There was 1 case of postoperative nerve stimulation symptoms in each group. One patient in the digital group was found necrosis of the femoral head at 6 months after operation. One patient in the control group was found heterotopic ossification at 8 months after operation. All patients were follow-up for 13 to 28 months with an average of 17.6 months. The volume of intraoperative blood loss and blood transfusion in the digital group were significantly less than those in the control group(P<0.05). The operation time in the digital group was shorter than that in the control group(P<0.05). The excellent and good rates of fracture reduction were 92.9%(14/15) and 85%(17/20) in the digital group and the control group respectively,and there was no statistical significance (P>0.05). The excellent and good rates of d'Aubigne Postal function evaluation were 86.7%(13/15) and 80%(16/20) respectively,and there was no significant difference(P>0.05).
Conclusion: The computer-assisted virtual reduction combined with 3D printing technique can reduce the operative time,volume of intraoperative blood loss and blood transfusion in acetabular surgeries for patients with acetabular fractures. The technique is an effective method for preoperative planning,which worth promoting. |
