Feasibility and efficacy of personalized 3D printed titanium alloy filler in the complex hip joint revision surgery
Objective To analyze the feasibility of using personalized 3D printing titanium alloy filler blocks in the revision and reconstruction of complex hip joint.Methods From March 2021 to January 2023,a total of 40 patients who required joint revision after total hip arthroplasty in the hospital were included in the study and randomly divided into the 3D printing group and the control group,with 20 patients in each group.The 3D printing group was given personalized 3D printing titanium alloy filling block technology for revision treatment,and the control group was given routine total hip joint revision treatment.The operation time,intr-aoperative blood loss,hip joint function score and complications were compared between the two groups.Re-sults The operation time[(120.56±8.13)min]and intraoperative blood loss[(312.57±24.65)mL]in the 3D printing group were lower than those in the control group[(132.67±8.27)min]and[(342.64±25.47)mL],and the differences were statistically significant(t=5.720,P＜0.001;t=4.647,P＜0.001).After treat-ment,the hip joint function score[(87.69±6.35)points]in the 3D printing group was higher than that in the control group[(72.56±6.27)points],and the difference was statistically significant(t=9.286,P＜0.001);the incidence of complications(5.00％)was lower than that in the control group(20.00％),and the difference was statistically significant(x2=4.706,P=0.030).Conclusion The application of personalized 3D printed ti-tanium alloy filling blocks in hip joint revision surgery for severe acetabular bone defects is outstanding,which can save operation time,reduce intraoperative bleeding,significantly improve postoperative hip joint function,and reduce the occurrence of related complications.
