Application of a Personalized Finite Element Analysis and 3D-Printed Navigation Template in the Treatment of Femoral Neck Fracture with Cannulated Screw

To investigate the feasibility and accuracy of combining a personalized finite element analysis with 3D-printed navigation template on treatment femoral neck fracture (FNF) cannulated screw. A total 60 patients as unstable FNT were evolved randomly divided into two groups. The subjects in study group examined using according to three-dimensional CT hip joint before operation then underwent femur complete implantation screw, whereas other 30 control screw conventional FNF treatment. biomechanics three screws more stable when they close bone cortex (< 3 mm). Furthermore, it was demonstrated that had effectively success rate one-time nail placement significant reduction distance talus than those group. At 12 months post-surgery, higher healing Harris functional score hip, well lower necrosis head compared Totally, combined application can not only improve effective placement, but also make line requirements biomechanical stability promote reduce risk necrosis.
