[Abstract]:The posterior malleolus anatomic locking plate was designed by using CT 3D reconstruction data and computer aided software. Methods Mimics 10.01 software was used to scan 20 cases of normal ankle joint and the statistical data were reconstructed. The posterior medial, posterolateral varus angle, twist height and safe area height of screw implantation were measured in pre-designed posterior malleolus anatomic locking plate. Posterior malleolus posterior lip width and other anatomical data. Ungraphics NX5.0 software was used to design the locking plate for posterior malleolus anatomy. The posterior malleolus anatomic locking plate template was made by using 3D printing technique. The plate model was verified in 15 fresh adult cadavers with posterior malleolus (removing all soft tissue of posterior malleolus and completely exposing the bone texture of posterior malleolus). Results the results showed that the medial posterior malleolus, the lateral varus angle gradually increased from the central axis of the posterior malleolus, the lateral torsion height decreased, the width of the posterior malleolus increased gradually from the top to the bottom, and the safety zone of the implanted screws was proportional to the height of the posterior malleolus. According to the measurement data, the plate design was completed, and the steel plate model was made. The 3D printed plate model was used in 15 fresh adult cadavers with the posterior malleolus (removing all soft tissue of the posterior malleolus). It was found that the plate was suitable for the matching of posterior malleolus, and the position and angle of the plate was ideal, which was in accordance with the design requirements of the anatomic locking plate of the posterior malleolus. Conclusion the design of posterior malleolus anatomic locking plate using CT 3D reconstruction data of ankle combined with computer aided technique software provides a valuable reference for the design of internal fixation apparatus.
