Metacarpal joint compression plate 4032012

proximaldistallocking

Product introduction
This locking metacarpal plate system provides angular-stable fixation through 20° conical threaded locking holes that engage matching screw heads, establishing a fixed plate–screw–bone construct. The plate is anatomically contoured for the hand, with a low-profile polished body and rounded edges to reduce soft-tissue irritation. Type I solid and Type II cannulated locking screws use matching 20° conical threads. Screw thread profiles are optimized by diameter: symmetric shallow threads for Φ1.5 mm and Φ2.0 mm to improve purchase in narrow shafts, and deeper threads for Φ6.5 mm and Φ7.3 mm to enhance fixation in cancellous bone. Components are manufactured from TA3G commercially pure titanium and TC4 titanium alloy.

Features

• Conical threaded screw head
  20° conical threaded screw heads precisely engage the plate locking holes, providing a reproducible locking interface and angular stability.
• Self-tapping cutting edges
  Screws include sharp self-tapping edges to facilitate insertion without the need for extensive pre-tapping in typical metacarpal applications.
• Colored anodized surface
  Surface anodization provides corrosion resistance and durable color coding for quick identification.
• Anatomical low-profile plate
  Plate geometry is contoured for metacarpal anatomy with a low-profile polished finish and rounded edges to minimise soft-tissue irritation.

Advantages

• Stable angular fixation
  Conical 20° locking interface and matched screws deliver stable angular fixation suitable for metacarpal and phalangeal constructs.
• Efficient implantation
  Self-tapping screw design and matched thread geometry support predictable insertion and handling in operative fixation.
• Tissue-preserving profile
  Low-profile polished plate and rounded edges reduce soft-tissue irritation while helping preserve periosteal blood supply around the fracture.

Indications

• Fractures of proximal, middle and distal phalanges
• Metacarpal fractures (transverse, oblique, comminuted)
• Intra-articular and extra-articular finger fractures
• Fractures requiring angular stability, including osteoporotic bone
• Malunions or nonunions of phalanges or metacarpals
• Corrective osteotomies of phalanges or metacarpals
• Reconstruction or stabilization after bone grafting for post-traumatic deformity
