Product IntroductionThe Metacarpal T locking plate 4034012 is a low‑profile, anatomically contoured implant designed for angular-stable fixation of phalangeal and metacarpal fractures. Its polyaxial locking holes with ball-threaded screw heads permit controlled multidirectional screw placement to match fracture pattern and cortical purchase while supporting minimally invasive approaches.
Key functional detailsThe plate features polyaxial locking holes with a ball-threaded interface enabling up to 15° screw angulation in any direction relative to the hole axis. Locking screws (Type II and cannulated Type III) have threaded spherical heads that engage the hole to form a stable angular construct. Φ1.5 mm and Φ2.0 mm screws for small-bone fixation use shallower threads to optimize purchase in thin cortices. Components are manufactured from TA3G commercially pure titanium or TC4 titanium alloy.
Features- Polyaxial locking interface with ball-threaded screw head for secure screw-to-plate fixation
- Flexible screw angulation: up to ±15° polyaxial angulation in all directions
- Self-tapping screw tips to facilitate insertion and bone engagement
- Anodized surface finish to improve intraoperative visibility and corrosion resistance
- Anatomical low-profile design with rounded edges and polished surface to reduce soft-tissue irritation
- Polyaxial locking without additional bushings simplifies instrumentation
Advantages- Reduced risk of cold welding at screw–hole junction due to interrupted thread design
- Intraoperative flexibility: screws can be reoriented or reinserted when required
- Ability to adapt screw trajectories to patient anatomy and complex fracture patterns
- Stable angular plate-to-screw construct suitable for osteoporotic or comminuted bone
Indications- Intra-articular and extra-articular fractures of phalanges and metacarpals
- Comminuted or complex small-bone fractures
- Osteoporotic fractures requiring angular stability
- Revision surgery after failed internal fixation
- Open or unstable fractures requiring multidirectional screw fixation
