• Low profile plate designs especially in the distal part of the plate for soft tissue protection
  • Oblong holes for minor plate adjustments
  • Consistent screw diameter of 2.5 mm for intraoperative simplicity
  • TriLock – multidirectional angular stability of ± 15° in all directions and in each screw hole*
  • K-wire holes to assist with temporary plate fixation
  • 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


  • Temporary internal fixation utilizes ligamentotaxis to obtain and maintain reduction
  • Neutralizes deforming forces across the wrist joint
  • No externally exposed hardware
  • Anatomical plate design for ease of intraoperative use
  • Fracture specific fixation: Straight plate for fracture fixation over the 2nd metacarpal
  • Fracture specific fixation: Curved plates (left and right) for fracture fixation over the 3rd metacarpal


Purple: APTUS 2.5


The two innovative spanning plate options allow different fracture patterns and the varying surgical preferences of surgeons to be easily addressed. The straight plate is designed for placement over the second metacarpal while the anatomically curved plates are optimized for placement over the third metacarpal. This novel design of the ingeniously curved plate helps to facilitate plate positioning and may reduce the entrapment of the extensor pollicis longus tendon due to the coronal bend1. The chamfered and narrowed plate ends facilitate the insertion during surgery. All plates feature a 12° dorsal bend for a neutral hand position, additional screw holes for direct buttressing of the scaphoid or lunate facet and our multidirectional and angular stable TriLock® locking technology.

The APTUS Wrist spanning plates are expressly designed to provide a new standard of care in distal radius fracture treatments requiring internal distraction plating.

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.
