Designed to Perform
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.
Plate Options
Three plate types are available for the fixation of distal humerus fractures. They allow, especially for complex fractures, pairwise positioning in either a 90° or 180° configuration. The three-dimensional plate shapes are based on comprehensive anatomical analyses for a good fit to the bone. [1] The thickness of the plates tapers off at the ends to reduce plate protrusion over the epicondyles distally and reduce the risk of stress fractures proximally. The innovative plate designs enable long transcondylar screws as well as bicortical screw placement proximally in both the 180° and the 90° configuration.

TriLock Medial Distal Humerus Plates 2.8
Highlights
-
Concave milling of the medial plate reduces its protrusion over the medial epicondyle [1]
-
A slight recess in anterior direction distally lowers the risk of contact between the ulnar nerve and the plate
TriLock Lateral Distal Humerus Plates 2.8
Highlights
-
The twisted plate shape reduces the necessary soft tissue detachment in the proximal area and may lessen postoperative soft tissue irritations [2]
-
Proximal screws can be placed bicortically distally even in the 180° configuration

TriLock Posterolateral Distal Humerus Plates 2.8
Highlights
-
Additional stability through two transcondylar screws connected via a flap to the plate
-
The two most distal screw holes in the plate are preangled to capture distal shear fragments of the capitellum
