• TriLock – multidirectional angular stability of ± 15° in all directions and in each screw hole*
  • Minimal screw head protrusion thanks to internal locking contour
  • Consistent screw diameter of 2.5 mm for intraoperative simplicity
  • Oblong hole for variable plate positioning and to facilitate axial compression
  • Rounded edges and a smooth surface for soft tissue protection
  • Plates are compatible with the screws and instruments of the APTUS Wrist Radius System 2.5

* Exception: oblong hole


  • Volar and dorsal plates for fusion of radius, scaphoid and lunate (RSL)
  • Physiological motion in the midcarpal joint is maintained
  • Anatomical plate designs for simple intraoperative use
  • Two screws can be inserted in each carpal bone
  • Double shaft design provides high rotational stability
  • Low plate profile of 1.6 mm

APTUS® Wrist

The wrist is a multi-articular joint. It consists of the carpus, distal ulna and distal radius. Fractures of the distal radius are the most common fractures in the human body. In recent years, great changes have taken place both in the treatment options of the distal radius and the patient demands which have increased. As socioeconomic factors have become more relevant, a perfect anatomic reconstruction and a permanent reduction have been targeted together with virtually no postoperative immobilization and very early rehabilitation.

With the APTUS Distal Radius System 2.5 Medartis offers a multidirectional and angular stable product line with implant plates in different designs, lengths and widths for a volar, dorsal and/or lateral approach. The APTUS Distal Radius System 2.5 plates with TriLock technology are anatomically adapted for an optimal stabilization of distal radius fractures and correction osteotomies as well as for arthrodesis.
