A Novel 3D-Printed Device for Precise Percutaneous Placement of Cannulated Compression Screws in Human Femoral Neck Fractures

Figure 2

The accuracy of computer-aided design and 3D printing technology for guide plate production. (a–d) The surgical procedure of 3D-printed guide plate-assisted percutaneous needle insertion and cannulated screw placement. (e–h) C-arm X-ray fluoroscopy was used to observe the cannulated compression screw placement. (i–l) Immediate postoperative CT was performed to evaluate fracture reduction and the position of the three cannulated compression screws.
