Home > Tibial Plateau Locking Plate (Proximal Tibia)
The proximal tibia locking plate is shaped for the lateral aspect of the tibial plateau, where the plate head must support the articular block while the shaft lies flush along the proximal lateral cortex. Its head carries a raft of locking screws directed upward toward the subchondral bone, giving fixed-angle support immediately below the joint surface, while combination holes along the shaft accept locking or standard cortical screws. Two curvature options — standard and large — match different plateau widths, and each curvature is manufactured separately for the left and the right leg, in versions with or without a screw-aiming guide. BoneCraft holds the complete variant run in stock, supplied as an independent distributor of genuine Zimmer Biomet products.
A proximal tibia locking plate works as a fixed-angle scaffold under the tibial plateau. The screws in the plate head run parallel to the joint surface and form a subchondral raft that resists depression of the articular block; the shaft then transfers the load to intact cortical bone further down the leg. Because the screws thread into the plate, the construct does not depend on friction between plate and bone, which keeps the reduction stable in metaphyseal comminution and in bone of reduced quality.
This line is offered in two curvatures. The standard curvature fits the average proximal tibia, while the large curvature accommodates a wider plateau or a larger stature, so the plate head follows the lateral flare without bending in theatre. Versions carrying an aiming guide allow the locking screws to be placed percutaneously through the guide; versions without the guide are contoured identically and accept the same screws. Final version selection rests with the operating surgeon.
The plate is used in the fixation of proximal tibia fractures involving the lateral plateau, including split, depression and split-depression patterns, and it can be placed through an open lateral approach or inserted subcutaneously and fixed percutaneously when the aiming-guide version is used. The precontoured head positions the raft screws below the subchondral bone of the plateau, and K-wire holes in the head allow temporary fixation to the bone before definitive screw placement. Fracture reduction, the choice of curvature and the final screw configuration are determined by the operating surgeon.
| Curvature | Hole counts | Side | Aiming guide |
|---|---|---|---|
| Standard curvature | 3, 5, 7, 9, 11, 13 and 15 holes | Left / Right | With or without guide |
| Large curvature | 3, 5, 7, 9, 11, 13 and 15 holes | Left / Right | With or without guide |
| Attribute | Data |
|---|---|
| Plate position | Lateral proximal tibia, anatomic head over the plateau flare |
| Hole pattern | Locking raft holes in the head; combination holes along the shaft |
| Screw compatibility | Locking screws and standard cortical screws of the matching large-fragment system |
| Material | Stainless steel, implant grade |
| Temporary fixation | K-wire holes in the plate head |
| Origin | Genuine original implant; original manufacturer documentation available |
As a genuine original implant, the plate head geometry, raft-screw angles and thread interfaces follow the published surgical technique of the original system without deviation, and the plates accept the instruments described there directly. Stock covers both curvatures and both legs across the full hole-count run, so a wholesale order can consolidate the complete matrix in one shipment.
