Abstract:
Objective To investigate preliminary clinical effects of three-dimensional(3D)printing combined with minimally invasive percutaneous plate osteosynthesis(MIPPO)in the treatment of anterior pelvic ring injuries.Methods Between December 2017 and July 2023,we treated 15 patients with anterior pelvic ring injuries by using 3D printing combined with MIPPO.Before surgery,a 3D model was printed to establish the actual structure,and a steel plate was pre-bent outside the body to simulate the surgery,as well as the design of number,direction,and length of screws.Then,the pre-bent internal fixation device was inserted through the bone membrane tunnel in the anterior pelvic ring,and the screws were fixed through both sides of the incision according to the preoperative planning.Results All the 15 patients underwent surgery successfully without complications such as nerve and vascular injury.The operation time was(162.9±63.1)min,the total length of incision was(13.5±2.2)cm,the number of fluoroscopic examinations during the surgery was(5.5±1.0)times,and the amount of blood loss was(456.7±272.5)ml.The fracture healing time was(17.5±1.8)weeks.The 15 patients were followed up for(15.2±3.9)months.The Majeed functional score increased significantly from(18.3±2.3)points before surgery to(86.3±6.0)points at 6 months postoperatively(t=-47.313,P=0.000).The fracture reduction according to the Matta standards showed excellent in 14 patients,fair in one patient,the excellent and good rate being 93.3％(14/15).Conclusion Combination of 3D printing and MIPPO treatment for anterior pelvic ring injuries can achieve good clinical effects.
