【摘要】：目的探讨3D打印技术辅助股骨远端截骨术(distal femoral osteotomy,DFO)治疗膝外翻畸形骨关节炎的临床疗效。方法2014年1月—2016年1月,收治膝外翻畸形骨关节炎患者12例(15膝)。男5例,女7例;年龄30~60岁,平均43.8岁。病程1~12年,平均6.6年。单膝9例,双膝3例。骨关节炎Koshino分级:Ⅰ级1例(1膝),Ⅱ级7例(9膝),Ⅲ级4例(5膝)。摄双下肢全长X线片,测量股胫角(femorotibial angle,FTA)为(160.40±2.69)°,远端股骨外侧角(anatomical lateral distal femoral angle,a LDFA)为(64.20±2.11)°。术前于Mimics软件设计截骨模块并3D打印,术中通过截骨模块确定最佳截骨方位进行截骨,最后行钢板及螺钉内固定。结果术后切口均Ⅰ期愈合,无感染、下肢深静脉血栓形成等并发症发生。患者均获随访,随访时间6~18个月,平均12.2个月。术后6个月膝关节HSS评分为(89.07±2.49)分,较术前(65.27±1.49)分显著提高(t= 28.31,P=0.00);获优10膝、良4膝、可1膝,优良率为93.3%。X线片复查示,患者截骨处均达骨性愈合,愈合时间2.9~4.8个月,平均3.3个月;1例(1膝)出现骨延迟愈合。术后6个月测量FTA为(174.00±1.41)°,a LDFA为(81.87±1.06)°,与术前比较差异均有统计学意义(t= 18.26,P=0.00;t= 25.19,P=0.00);下肢力线位置测量显示内侧胫骨平台占整个胫骨平台百分比为49.78%±0.59%,与术中测量的49.82%±0.77%比较,差异无统计学意义(t=0.14,P=0.89)。结论DFO治疗膝外翻畸形骨关节炎时,3D打印截骨模块可辅助术中股骨远端精确截骨,获得满意临床疗效。
[Abstract]:Objective to investigate the clinical effect of 3D printing assisted distal femur osteotomy in the treatment of osteoarthritis with valgus deformity. Methods from January 2014 to January 2016, 12 patients with osteoarthritis of valgus deformity were treated, including 5 males and 7 females. The average age was 43.8 years. The course of disease ranged from 1 to 12 years, with an average of 6.6 years. There were 9 cases of single knee and 3 cases of double knee. Koshino classification of osteoarthritis was as follows: 1 case of grade 鈪，
