Three-Dimensional Printing Technology Based on Digital Orthopedics: 5-Point Positioning Point-Contact Pedicle Navigation Template in the Case of Scoliosis and Complex Pedicle.

The 5-point positioning point-contact pedicle navigation template features a claw-like structure that securely adapts to various deformed vertebral facet joints, avoiding drift phenomena and ensuring accurate screw placement. Its pointed contact structure with the lamina of the spine avoids extensive and complete detachment of posterior structures, reducing blood loss, surgery time, and trauma. Predesigned pedicle screw entry points and directions reduce fluoroscopy frequency and surgery time.
