The FIRST Stable and Anatomically Aligned Hemi-Arthroplasty
of the Proximal Radio-Ulnar Joint…
- Long stem design provides three point fixation for a solid press fit
- Distal stem flutes for rotational stability
- Ti plasma spray
Head Locking Mechanism
- Tapered cutting splines positively engage and permanently lock the ball
- Patented internal threads resist loosening of the lock screw
- Side loading head
- Atraumic dish edges minimize capitellar wear
Restoring the Native Anatomy
The axis of forearm rotation courses from the ulnar fovea to the center of the radial head.
The prosthetic radial head must be oriented perpendicular to this axis.
The proprietary Head Alignment Tool
aligns the prosthetic head to the axis
of forearm rotation, restoring the kinematics
of the proximal radio-ulnar joint.
The head is then locked permanently into position.
