摘 要:Background:Surgical treatment of both-column acetabular fractures is challenging because of the complex acetabular fracture patterns and the curved surface of the acetabulum.Seldom study has compared the application of three-dimensional(3D)printing technology and traditional methods of contouring plates intra-operatively for the surgical treatment of both-column acetabular fractures.We presented the use of both 3D printing technology and a virtual simulation in pre-operative planning for both-column acetabular fractures.We hypothesized that 3D printing technology will assist orthopedic surgeons in shortening the surgical time and improving the clinical outcomes.Methods:Forty patients with both-column acetabular fractures were recruited in the randomized prospective case-control study from September 2013 to September 2017 for this prospective study(No.ChiCTR1900028230).We allocated the patients to two groups using block randomization(3D printing group,n=20;conventional method group,n=20).For the 3D printing group,1:1 scaled pelvic models were created using 3D printing,and the plates were pre-contoured according to the pelvic models.The plates for the conventional method group were contoured during the operation without 3D printed pelvic models.The operation time,instrumentation time,time of intra-operative fluoroscopy,blood loss,number of times the approach was performed,blood transfusion,post-operative fracture reduction quality,hip joint function,and complications were recorded and compared between the two groups.Results:The operation and instrumentation times in the 3D printing group were significantly shorter(130.8±29.2 min,t=-7.5,P<0.001 and 32.1±9.5 min,t=-6.5,P<0.001,respectively)than those in the conventional method group.The amount of blood loss and blood transfusion in the 3D printing group were significantly lower(500[400,800]mL,Mann-Whitney U=74.5,P<0.001 and 0[0,400]mL,Mann-Whitney U=59.5,P<0.001,respectively)than those in the conventional method group.The number of the approach performed in the 3D
