Patient-Specific Glenoid Pin Guide for Precise Screw Trajectories

The surgical plan is created in advance using pre-operative imaging data (CT or MRI scans), allowing the surgeon to precisely determine screw trajectories, depths, and positions before surgery. This preliminary planning enables optimal screw placement that maximizes fixation strength while avoiding soft tissue structures, as the exact bone geometry and surrounding tissues are known beforehand.

Patient-specific instruments are manufactured as physical copies or replicas based on the patient's unique bone anatomy derived from imaging data. These instruments include guides and templates that replicate the pre-planned screw trajectories, allowing the surgeon to transfer the virtual surgical plan into the actual surgery with high precision, ensuring screws follow the optimal paths determined during planning.

Patient-specific instruments are created as customized copies based on the patient's unique anatomy obtained from pre-operative imaging. These instruments include patient-specific guides, templates, and positioning devices that are manufactured to match the individual patient's bone geometry, enabling precise implant placement that accounts for anatomical variations specific to each patient.

All customization and planning are performed in advance before surgery. The patient-specific instruments are manufactured beforehand based on imaging data, and the surgical plan is finalized prior to the procedure. This preliminary preparation eliminates the need for complex intraoperative adjustments and simplifies the actual surgical execution despite the customized nature of the instruments.
