Medartis | Distal Humerus System 2.8

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 intraarticular. They may involve several bones and are frequently associated with ligamental injuries. In these cases, the restoration of the original 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.

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 even in the 180° configuration

BMC Musculoskelet Disord

Crönlein et al., report on the a prospective study, in which 20 patients with a distal humerus fracture were randomized for osteosynthesis with either DePuy Synthes VA-LVP or Medartis APTUS Elbow plates.The authors find that :"Even though there might be a trend of some advances of the Medartis Aptus Elbow plating system concerning postoperative ROM and elbow scoring, a crucial difference in the overall clinical outcome between the two plating systems could not be detected in the short-term follow-up."
