O’nil locking olecranon plates provide excellent fixation of the proximal ulna for fractures and osteotomies.

Anatomic and pre-shaped, they can be positioned directly above the tricipital tendon.

The unique conical screw-plate locking mechanism ensures fracture stability whist avoiding pressure on the bone, preserving vascularity and accelerating the return of the patient’s previous mobility and function.


  • Anatomical design, low profile plate
  • The patented screw-plate locking system allows easy locking of the screws, eliminates the risk of cross threading between the screw and plate, and ensures a simple operative technique
  • Bicortical fixation
  • Screw positions allow a perfect alignment of the proximal olecranon and address multiple fracture patterns
  • Diamagnetic steel (AISI 316 LVM – ISO 5832-1) plates allow MRI; screws and bushes are made of titanium (Ti6AI4V – ISO 5832-3)
  • Simple and intuitive Instruments for reduced surgery times
