摘　　要：目的研究3D打印技术辅助空心加压螺钉治疗Andersonll A型齿状突骨折的临床疗效。方法选取我院2014年1月~2017年1月收治的AndersonⅡA型齿状突骨折患者40例,按随机数字表法分为观察组(n=21,行3D打印辅助空心加压螺钉治疗)和对照组(n=19,行单纯空心加压螺钉治疗)。比较两组手术相关指标(手术成功率、手术时间、术中出血量、透视次数、置钉次数),骨折临床愈合时间和螺钉松动断裂发生率,术前和术后1月日本骨科学会评分(JOA),颈椎活动度(CROM),美国脊髓损伤学会评分(ASIA)。结果两组手术成功率均为100%,观察组相比于对照组,手术时间更短、术中出血量更少、透视次数更少、置钉次数更少,差异具有统计学意义(P<0.05)。观察组骨折临床愈合时间短于对照组,螺钉松动断裂发生率低于对照组,差异具有统计学意义(P<0.05)。两组术前JOA、CROM、ASIA差异无统计学意义(P>0.05)。两组术后1月JOA、CROM、ASIA评分高于术前,差异具有统计学意义(P<0.05)。两组术后1月JOA、CROM、ASIA评分差异无统计学意义(P>0.05)。结论 3D打印技术辅助空心加压螺钉能减少手术时间、术中出血量、透视次数和置钉次数,骨愈合快,螺钉松动断裂少。Objective To explore the clinical effects of cannulated compression screws assist with 3D printing technique in treatment of odontoid fracture of Andersonll A type. Methods Forty patients with odontoid fracture of Anderson II A type in our hospital from January 2014 to January 2017 were selected. They were divided into 2 groups according to the random number table. The observation group （n=21）was treated by 3D printing with annulated compression screws and the control group （n=19） was treated by annulated compression screws. Success rate, operation time, amount of bleeding, X-ray frequency, screw placement frequency, bone healing time, rate of screw loose and JOA, CROM, ASIA score were compared. Results Two groups had the 100% success rate of operation. The operation time, amount of bleeding, X-ray frequency and screw placement frequency of observation group were lower than that of control group （P〈0.05）. The bone healing time and the rate of screw loose of observation group was less than that of control group （P〈0.05）. The Japanese Orthopaedic Association Scores （JOA）, Cervical range of motion （CROM）, American Spinal Injury Association （ASIA） score in preoperative of two groups had no significant difference （P〉0.05）. The JOA, CROM, ASIA score at a month after operation were higher than preoperative groups （P〈0.05）. The JOA, CROM, ASIA score at a month after the operation of two groups had no significant difference （P〉0.05）. Conclusion 3D printing with annulated compression screws can decrease the operation time, amount of bleeding, X-ray frequency and screw placement frequency. It can promte the bone healing, and decrease the rate of screw loose.
