Objective This study aimed to compare the clinical effectiveness of 3D printing screw guides with navigation in assisting surgery for sacroiliac screw placement.Methods We retrospectively analyzed clinical data from 32 patients who underwent surgical treatment for sacroiliac joint injuries using sacroiliac screws between June 2018 and June 2021.Patients were divided into two groups:The 3D printing screw guide group(17 cases)and the navigation group(15 cases).In the 3D printing screw guide group,13 males and 4 females with a mean age of(37.81±9.73)years old(range:23～56 years old)were included,with 10 cases of Tile type B and 7 cases of type C.The navigation group comprised 12 males and 3 females with a mean age of(36.23±9.35)years old(range:23～58 years old),including 9 cases of Tile type B and 6 cases of type C.We compared intraoperative fluoroscopy frequency,screw placement time,intraoperative blood loss,and postoperative complications between the two groups.Pelvic function was evaluated one year postoperatively using the Majeed score,and fracture reduction was assessed using Matta criteriaResults There were no wound infection or nerve injury complications in either group.All patients were followed up for an average of(19.82±0.25)months(range:12～32 months).Comparisons between the two groups revealed no significant difference in intraoperative fluoroscopy frequency(P＞0.05).However,intraoperative blood loss was higher in the 3D printing screw guide group than in the navigation group(P＜0.05).Conversely,screw placement time was shorter in the 3D printing screw guide group compared to the navigation group(P＜0.05).According to Matta criteria,the 3D printing screw guide group had 12 excellent,4 good,and 1 fair cases,while the navigation group had 11 excellent,3 good,and 1 fair cases(P＞0.05).According to Majeed score at one year after operation,ranged from 67 to 93,mean(85.76±6.86)in 3D printing screw guide group,and ranged from 68 to 92,mean(86.47±7.37)in the navigation group(P＞0.05).Conclusion The use of 3D printing screw guides in assisting sacroiliac screw placement surgery offers advantages such as reduced screw placement time,accurate nail placement,and does not require high-tech equipment.This approach could be promoted in clinical practice.
