Construction and Biomechanical Properties of PolyAxial Self-Locking Anatomical Plate Based on the Geometry of Distal Tibia
Figure 3
(a)-(b)Design of polyaxial self-locking anatomical plate, anteversion, 5.1°~9.3°; twisting section, 9°~20°; twisting section, 22°~40°; twisting section, 49°~62°; twisting section, 62°~88°. (c) The polyaxial self-locking bushing is situated within the polyaxial hole, which is round shaped from the top view with a C-shaped defect. On the obverse surface of the bushing, there are three triangularly distributed small concaves. (d) A cross sectional view of the polyaxial self-locking bushing shows that it is bucket-shaped with a polished outer surface and threaded inner surface.
