The Two-Hole Polyaxial Locking Plate is a low-profile, anatomically contoured titanium plate designed for fracture fixation in the foot and ankle.
The plate features 30° conical polyaxial locking holes, allowing locking screws to be positioned up to ±15° off-axis. This variable-angle design accommodates complex fracture geometries while maintaining a fixed-angle screw-plate construct after locking.
The plate and corresponding locking screws are manufactured from titanium alloy and feature a Type II anodized finish. The locking interface forms a rigid bone-screw-plate construct, while the rounded edges and polished, low-profile surfaces are designed to reduce tendon and soft-tissue irritation.
Conical locking holes with internal threads accept locking screws at variable angles of up to ±15° off-axis, providing flexibility in screw positioning while maintaining angular stability.
The locking screws feature a threaded, spherical head that engages the plate hole from different directions. Once locked, the screw and plate form a stable fixed-angle construct.
The plate and screws are made from titanium alloy with a Type II anodized surface finish, providing the material and surface characteristics specified for the system.
Sharp screw tips provide self-tapping functionality, helping simplify screw insertion and reducing the need for separate pre-tapping steps.
The plate is pre-contoured to the anatomy of the foot and ankle. Beveled and rounded edges help reduce the potential for soft-tissue irritation.
The slim plate profile and smooth, polished surface are designed to minimize implant prominence beneath the skin.
The locking holes incorporate discontinuous threads to reduce the risk of cold welding between the locking screw head and the plate.
Direct engagement between the locking screw heads and plate creates a rigid fixed-angle construct that supports stable fracture fixation. The configuration is particularly suited to applications involving osteoporotic or comminuted fractures.
Screws can be directed within the ±15° polyaxial range, allowing the surgeon to select screw trajectories according to fracture geometry and available bone.
Because the locking mechanism secures the screws to the plate without requiring the plate to be tightly compressed against the bone, the design can help limit disruption at the bone-plate interface.
The low-profile, polished plate with rounded edges is designed to minimize implant prominence and reduce potential irritation to surrounding tendons and soft tissues.
Locking screws engage directly with the plate, eliminating the need for separate locking sleeves or inserts and helping streamline the implantation process.
The locking-hole design allows screws to be removed and reinserted when required, supporting intraoperative adjustment or revision procedures.
The use of two proximal screws can help stabilize a bone segment against rotational movement, supporting fixation of smaller fracture fragments.
The interrupted-thread configuration is designed to reduce the risk of cold welding at the screw-plate interface while maintaining direct locking between the components.
The Two-Hole Polyaxial Locking Plate is intended for internal fixation of fractures and corrective procedures in the forefoot and midfoot, including:
