Pangea Design Variable Angle Locking Technology Pangea’s variable angle locking technology uses a CoCr locking screw, which is harder than the Ti6Al4V ELI plate, allowing for the screwhead’s threads to form a definitive locking position in the plate’s locking hole by engaging the softer, Ti6Al4V ELI material. This technology allows the user to aim and lock the screw into the plate within a true 30° cone of the predetermined hole trajectory. The variable angle drill guide provided with the system offers guidance with respect to the limit of the 30° cone. The locking mechanism remains functional for up to three attempts at locking screw insertion. Circular universal holes accept nonlocking screws, and locking screws within a 30° cone 1.6mm K-Wire Hole K-wire holes at distal aspect Oblong Hole To aid in plate placement 3.5mm Screws in the Shaft 3.5mm screw holes in the shaft and 2.7mm screw hole options distally for versatile fixation option 2.7mm Distal Row Accepts variable angle locking screws to reduce the potential for implant prominence and allow for capture of articular fragments Distal Cluster Designed to sit immediately medial to the posterior aspect of the tibial incisura Placement The plate is placed on the posterior surface of the distal tibia, specifically to sit on the lateral side of the posterior surface over the posterior malleolus Proper position is achieved when the distal end of the plate is adjacent to the articular surface, allowing for the distal screws to support the plafond. Contour of the distal plate is designed to allow placement immediately proximal to the joint line for rafting while reducing plate prominence. Fit Distal Posterior Tibia Plate is designed to act as a buttress of the posterior malleolus or posterior fixation of pilon fractures. The rotation of the plate is designed to allow for central placement on the tibial shaft while facilitating capture of the posterior malleolus. The fit and placement is designed to reduce the potential for irritation of the flexor hallucis longus (FHL tendon). Designed with the use of SOMA: Stryker Orthopedics Modeling and Analytics. SOMA analysis shows better anatomic plate fit of the Distal Posterior Tibia plate compared to competitive VA-LCP distal tibia plates. 2 Indications The Pangea Tibia Plating System is indicated for the internal fixation and stabilization of tibia bone fractures and osteotomies in normal and osteopenic bone, including: Diaphyseal, metaphyseal, epiphyseal, extra- and intra-articular fractures Non-unions, malunions, and deformities Periprosthetic fractures Approaches Surgeons may use a posteromedial or posterolateral approach to the distal posterior tibia. When using a posterolateral approach, care must be taken to protect the sural nerve.
