The distal humerus is of a fixed-hinge design, which reproduces the anatomical axis of rotation of the elbow joint.
The humeral component of the elbow has a similar shape of the natural condyles and provides a highly polished site, mimicking the capitulum in case the radial head is preserved.
Posteriorly, it provides a highly polished groove for the tendon of the triceps muscle and a region to house the olecranon during the full extension of the elbow.
The ulnar stem is curved to follow the anatomical shape of the natural ulna. The minimum resection distance from the axis of rotation is 56 mm. Thereafter longer resections can be reached by adding extensions at 10 mm intervals.
The distal humerus can accommodate modular osseointegration rings to match the resected bone.
