• Medial plate with recess to protect the ulnar nerve
  • Decreasing plate thickness at the plate end
  • Concave plate
  • Increased stability at the level of the fracture zone
  • Oblong hole for pre-fixation (2.8 mm cortical screw)
  • Compression hole
  • Screw holes for 2.8 mm TriLock locking or cortical screws
  • 1.8 mm K-wire holes


  • Anatomic plate design supports fracture reduction    
  • Insertion of transcondylar TriLock locking screws in the distal condylar bone 
  • Medial, lateral and posterolateral plate designs allow both 90° and 180° double plate configuration              
  • Low profile plates for maximum soft tissue protection Plates can be contoured to address anatomic variations 
  • Numerous intra-operative fixation options to address complex fractures due to a large number of screw holes
  • No lateral protrusion of the medial plate                       
  • Protection of the ulnar nerve with the medial plate     
  • Reduces lateral soft tissue dissection proximally with the lateral plate
  • Good incorporation of distal fragments of the Capitulum by the posterolateral plate       
  • Attachment of transcondylar screws with the posterolateral plate via a lateral flap
  • Reduction in plate thickness at the proximal end reduces the peak stresses in the humerus shaft
  • Easy to use system thanks to uniform screw dimension of 2.8 mm

APTUS® Elbow

The elbow is a complex joint with several articulating surfaces where the humerus, the radius and the ulna meet. Stability is achieved by a high number of ligaments and muscles attaching at the elbow. Fractures caused by direct or indirect trauma are quite frequent and often intra-articular. They may involve several bones and are frequently associated with ligamental injuries. In these cases, the restoration of the initial function of the articulation is very challenging.

Because the elbow has a strong tendency to stiffen after injury, early mobilisation is paramount. This can often only be achieved by open reduction and internal fixation. Medartis is developing a comprehensive range of plates, carefully matched to the complex anatomy of the elbow. These implants take advantage of Medartis' innovative TriLock technology providing multidirectional angular stability, which is beneficial for the treatment of intra-articular fractures of the elbow.
