The metacarpal T locking plate is designed with advanced threaded polyaxial locking holes, enabling a secure plate-screw-bone locking construct that provides angular stability.
Unlike traditional compression plates which require extensive soft tissue and periosteal dissection—often increasing the risk of complications—the polyaxial locking system offers a minimally invasive alternative with enhanced fixation.
Each locking hole features four internal threaded sections, allowing up to 15° off-axis screw angulation in all directions.
This design empowers surgeons to select the most optimal screw trajectory, adapting fixation to specific fracture patterns or cortical areas and improving anatomical conformity.
The plate’s low-profile body is anatomically contoured, with rounded edges and a highly polished surface, minimizing soft tissue irritation and improving patient comfort.
The locking screws (Type II and cannulated Type III) are equipped with a threaded spherical head, which locks securely within the polyaxial hole, forming a stable angular fixation once the screw is fully inserted.
To ensure optimal mechanical performance:
● Φ1.5 mm and Φ2.0 mm screws feature shallow threads to enhance grip in finer bone.
All components are manufactured from TA3G pure titanium or TC4 titanium alloy, offering excellent biocompatibility, strength, and fatigue resistance.
● Ball-threaded screw head design compatible with polyaxial locking and compression holes
● Surface treated with colored anodization for enhanced visibility and corrosion resistance
● Sharp self-tapping screw tip for easier insertion and improved bone engagement
● Allows up to 15° angulation in all directions from the hole axis for flexible screw placement
● Anatomically contoured low-profile plate with rounded edges and highly polished surface to minimize soft tissue irritation
● Interrupted thread design reduces risk of cold welding at thread junctions
● Screws can be inserted at optimal angles to accommodate clinical variation in anatomy
● Rigid plate-to-screw locking interface ensures high mechanical stability and safety
● 15° polyaxial screw angulation offers personalized solutions for complex fracture types
● Re-insertion of screws is possible when needed, enhancing intraoperative flexibility
● Provides anti-rotational stability for fracture fragments using two screws in key locations
● No additional components (e.g., bushings) are required to achieve polyaxial locking, making the system simple and efficient to use
● Plate shape is designed specifically for the anatomical structure of the application site, minimizing soft tissue disruption
