【摘要】：目的:探讨3D打印技术辅助外固定架治疗足踝畸形的临床应用。方法:回顾性分析广西医科大学第一附属医院创伤骨科手外科2014年4月—2017年1月足踝畸形行外固定架矫正治疗48例患者(53足),年龄5-60岁,平均年龄16岁,随访时间2—34个月,平均随访时间17个月。分为3D打印技术辅助组和传统手术组。3D打印辅助组24足,传统手术组29足,采用美国足踝外科学会AOFAS(AOFAS Ankle Hindfoot Scale)踝-后足评分进行疗效评价,所得数据用SPSS17.0软件进行统计学分析。结果:本研究通过回顾性分析3D打印技术辅助组和传统手术组患者的年龄、性别构成比无统计学差异。术后根据美国足踝外科学会AOFAS(AOFAS Ankle Hindfoot Scale)踝-后足评分,总48例(53足)患者中优26足,良17足,一般9足,差1足,优良率81.1%,复发1足;其中,3D打印组患者24足中,优14足,良7足,一般3足,差0足,优良率87.5%,复发0足;传统手术组29足中,优12足,良10足,一般6足,差1足,优良率75.8%,复发1足;3D组优良率较传统组高11.7个百分点。根据美国足踝外科学会AOFAS踝-后足评分(AOFAS Ankle Hindfoot Scale)评分系统对两组患者术前术后评分,3D打印技术辅助组术前平均得分48.0±15.5,术后得分88.0±10.1,传统手术组术前平均得分47.0±14.2,术后得分80.0±13.5,术前两组间患者均数标准差比较P0.05,术前患足畸形基数资料无统计学意义;术后两组间患者采用均数标准差比较P0.05,术后两组间根据美国足踝外科学会AOFAS(AOFAS Ankle Hindfoot Scale)踝-后足评分有统计学意义,即3D打印技术辅助组患者较传统手术患者术后疗效满意。结论:3D打印技术辅助外固定架治疗足踝畸形,能更好的分析足踝畸形和模拟手术,从而制定更精准的术前计划,从而获得更好的术后效果,值得推广应用。
[Abstract]:Objective: to explore the clinical application of 3D printing assisted external fixator in the treatment of foot and ankle deformity. Retrospective analysis of 48 patients with ankle deformity treated with external fixator from April 2014 to January 2017 in the Department of Orthopedic Trauma, Department of Orthopedics, first affiliated Hospital of Guangxi Medical University. (. 53 feet. Age 5-60 years, mean age 16 years, follow-up time 2-34 months, average follow-up time 17 months, divided into 3D printing assisted group and traditional operation group .3D printing assisted group 24 feet. The curative effect was evaluated by AOFAS(AOFAS Ankle Hindfoot scale score of the American Society of foot and ankle surgery (AOFAS(AOFAS Ankle Hindfoot scale) in the traditional operation group (29 feet). The data were analyzed statistically by SPSS17.0 software. Results: the age of patients in 3D printing assisted group and traditional operation group was analyzed retrospectively. There was no significant difference in sex composition. The ankle-hind foot score was evaluated according to the AOFAS(AOFAS Ankle Hindfoot scale scale of the American Society of foot and ankle surgery. The total 48 cases (53 feet) were excellent in 26 feet, good in 17 feet, fair in 9 feet, poor in 1 foot, excellent and good rate was 81.1, recurrence in 1 foot; Of the 24 patients in the 3D printing group, 14 were excellent, 7 were good, 3 were fair, 0 were poor, the excellent and good rate was 87.5, and the recurrence was 0; Of 29 feet in the traditional operation group, 12 were excellent, 10 were good, 6 were fair, 1 was poor, the excellent and good rate was 75.8and the recurrence was 1; The excellent and good rate of 3D group was 11.7% higher than that of the traditional group. According to the AOFAS ankle-hind foot score of the American Society of foot and ankle surgery, AOFAS Ankle Hindfoot scale was used. The score system was used to evaluate the patients before and after operation. The mean preoperative score was 48.0 卤15.5in the 3D printing assisted group, 88.0 卤10.1 in the postoperative group and 47.0 卤14.2 in the traditional operation group. The postoperative score was 80.0 卤13.5.The mean standard deviation between the two groups was higher than that before operation (P0.05). The mean standard deviation was compared between the two groups after operation (P0.05). There was statistical significance between the two groups according to the ankle-hind foot score of the American Society of foot and ankle surgery (AOFAS(AOFAS Ankle Hindfoot scale). Conclusion the treatment of foot and ankle deformity with the help of 3 D printing technique can better analyze foot ankle malformation and simulate operation. In order to make more accurate preoperative plan and obtain better postoperative effect, it is worth popularizing.
