目的评估3D打印导板辅助空心螺钉内固定术治疗不稳定性骨盆骨折的疗效。方法回顾分析2015年5月—2016年6月采用3D打印导板辅助空心螺钉内固定术治疗的10例不稳定性骨盆骨折患者临床资料。男7例,女3例;年龄20~58岁,平均37.5岁。致伤原因:高处坠落伤5例,重物压伤1例,交通事故伤4例。伤后至入院时间1~5 h,平均3.1 h。骶骨骨折6例,右侧骶髂关节脱位1例,髂骨骨折3例;10例均有耻骨上下支骨折,左侧3例(其中2例耻骨上支骨折邻近耻骨联合),右侧2例,双侧5例。骨折Tile分型:B2型4例,B3型1例,C1型4例,C2型1例。术后根据Matta评分标准进行影像学评估,根据CT三维重建评估骶髂螺钉和耻骨上支螺钉位置,按照Majeed功能评分进行功能评估。结果患者平均每枚螺钉植入时间为30 min,平均每枚螺钉切口失血量为50 mL。每枚骶髂螺钉植入透视时间为24~96 s,平均62 s;每枚耻骨上支螺钉植入透视时间为42~80 s,平均63.2 s。住院时间17~90 d,平均43.7 d。术后患者切口均Ⅰ期愈合。患者均获随访,随访时间12~22个月,平均15.6个月。术后1 d根据Matta评分标准评定获优8例,良2例;CT三维重建示9枚骶髂螺钉位置均为Ⅰ类,13枚耻骨上支螺钉位置均为0级。随访期间均未出现血管神经损伤,螺钉退出、断裂,继发性骨折移位等并发症。术后6个月X线片示骨折均已愈合。术后1年根据Majeed功能评分评价功能,获优9例,良1例。末次随访时,合并左侧L5神经根损伤的Tile C2型患者L5神经根功能恢复正常。结论 3D打印导板辅助空心螺钉内固定术治疗不稳定性骨盆骨折有助于精确植入螺钉、降低血管神经损伤风险,是治疗不稳定性骨盆骨折的一种较好选择。
Objective To evaluate the effectiveness of unstable pelvic fractures treated by cannulated screw internal fixation with the assistance of three-dimensional （3D） printing insertion template. Methods The clinical data of 10 patients who underwent surgical treatment for unstable pelvic fractures by cannulated screw internal fixation with the assistance of 3D printing insertion template between May 2015 and June 2016 were retrospectively analysed. There were 7 males and 3 females with an average age of 37.5 years （range, 20-58 years）. The causes of injury included falling from height in 5 cases, crushing from heavy load in 1 case, and traffic accidents in 4 cases. The interval from injury to admission was 1-5 hours （mean, 3.1 hours）. The fracture situation included 6 cases of sacral fracture, 1 case of right sacroiliac joint dislocation, and 3 cases of iliac bone fracture. There were 10 cases of superior and inferior pubic rami fracture, including 3 cases on the left side （2 cases of suprapubic fracture adjacent to symphysis pubis）, 2 cases on the right side, and 5 cases on the bilateral. All fractures were classified according to the Tile system, there were 4 cases of type B2, 1 of type B3, 4 of type C 1, and I of type C2. The radiological outcome was evaluated by Matta scale, and the positions of the iliosacral screw and superior pubic ramus screw were evaluated according to 3D reconstruction of CT postoperatively. The functional outcome was evaluated by Majeed function scale. Results The average time of each screw implantation was 30 minutes, and the average blood loss per screw incision was 50 mL. The time of implantation of each sacroiliac screw was 24- 96 seconds （mean, 62 seconds）, and the time of implantation of each suprapubic screw was 42-80 seconds （mean, 63.2 seconds）. The hospitalization duration was 17-90 days （mean, 43.7 days）. All incisions healed by first intention. All patients were followed up 12-22 months （mean, 15.6 months）. The radiological outcome was excellent i
