Abstract: Objective To explore the value of 3D printing technique in the surgical management and strategy of rehabilitation
therapy of acetabular fracture. Methods For a patient with acetabular fracture, the pelvis model was printed preoperatively by
3D printing technique for surgical simulation to determine the optimal position of the screw, measure the screw length, and
design the route of screw entry. Laparoscopic assisted internal fixation was performed, and a gradual and systematic
rehabilitation plan was carried out after the surgery based on the results of simulation. Results The operation was completed
successfully with a shortened postoperative recovery time. Conclusions The application of 3D printing allows more accurate
and safer surgical management of acetabular fracture to promote postoperative recovery of the patient and lower the medical
costs.
