The A.L.P.S. Proximal Tibia plates represent the next generation in anatomic locked plating of tibial plateau fractures. It combines the benefits of low profile titanium plate metallurgy with the advantages of double row, multi-planar locked subchondral screw technology. These features allow the formation of a three-dimensional matrix of fixed and variable angle screws beneath the articular surface to create a true subchondral scaffold that is designed to provide strong fixation in both comminuted fractures and osteopenic bone.
The A.L.P.S. Proximal Tibia Plating System is composed of anatomically-contoured plates that are intended to provide plate conformity and subchondral support, and are low-profile to minimise soft tissue irritation. They feature a unique, double row of proximal screws designed to accommodate 4.0mm and 3.5mm locking and non-locking screws. This allows sequential stabilisation in multiple planes.
The A.L.P.S. Proximal Tibia Plate is pre-contoured to mimic the anatomy of the proximal tibia for optimum bone conformance. Low-profile contouring is intended to minimise prominence and soft tissue irritation. Plates are available in standard and large curve sizes to accommodate the variance in lateral metaphyseal flare from patient to patient.
F.A.S.T. Guide Inserts facilitate fast, accurate drilling that are pre-loaded and disposable requiring no intra-operative assembly. Adaptors allow for 1.6mm K-wires to be inserted over F.A.S.T. Guide Inserts for optimal temporary fixation.
4.0mm and 3.5mm tapered, threaded screws lock into position when tightened to establish a fixed angle construct for fixation or when optimal screw purchase is required. 3.5mm low profile non-locking screws provide the same low-profile design as locking screws for minimum soft tissue irritation. 3.5mm locking multi-directional screws (MDS) allow for up to a 25 degree cone of angulation for greater fixation range.
The A.L.P.S. Proximal Tibia Plates are specifically designed to match the anatomy of the proximal tibia while still having the required strength. This is achieved by offering two distinct lateral proximal tibia plate shapes. The distinction lies with the shape of the slope between the head and the shaft of the plate at the metaphyseal flare. These two plates are categorised as the standard and large curve plates both available in 3, 5, 7, 9, 11, 13 and 15 hole plates.
Diverging raft row screws and dual kickstand screws offer optimum subchondral support. Dual raft rows allow sequential stabilisation among multiple planes engineered from TiMAX® for strength, biocompatibility and enhanced imaging capabilities over stainless steel.
