Medartis | Radial Head System 2.0

Designed to perform.

The APTUS radial head plates 2.0 provide two plate options for treatment of complex multifragment fractures of the radial head. The radial head rim plate is designed to fix complex and/or comminuted fractures of the radial head requiring subchondral support. The radial head buttress plate is designed to fix osteotomies and fractures in the neck region of the radial head, particularly impacted fractures requiring buttressing. This plate shape allows a combination with isolated headless compression screws (CCS) outside the plate for additional subchondral support. Due to their anatomical fit, low plate profile and ease of bending, the plates may help to reduce soft tissue irritations. ^[1]

Products

TriLock Radial Head Rim Plate 2.0

WEG GL Radial Head RIM plate

Highlights

Positioning is close to the rim of the joint surface of the radial head and underneath the annular ligament
Plate geometry allows for subchondral screw positioning
Anatomical design facilitates reduction of fragments to the plate
Grid structure of the plate with offset screw positioning provides rotational stability

Features

TriLock

Multidirectional locking, screws can pivot freely by ± 15° in all directions

Simplified screw pick-up due to self-holding technology

Rounded edges

Rounded edges for soft tissue protection

Bendable

Plates can be bent with specific plate bending pliers

TriLock Radial Head Buttress Plate 2.0

Web GL Radial Head Buttress Plate

Highlights

Positioning is distal to the radioulnar joint surface and the annular ligament
Particularly suitable for fractures with defects in the neck region ^[2]
Can be combined with isolated screws for fixation of head fragments

The science behind.

Ex situ reconstruction of comminuted radial head fractures: is it truly worth a try?
Everding J, Raschke MJ, Polgart P, Grüneweller N, Wähnert D, Schliemann B.

2019

Arch Orthop Trauma Surg.

In this paper, Everding et al. investigate the outcomes of 9 patients with complex radial head fractures, who underwent an ex situ reconstruction of the radial head. The authors conclude that: "Ex situ radial head reconstruction can be a reliable option in the surgical treatment of complex radial head fractures associated with severe elbow trauma.

Using an anatomically preshaped low-profile locking plate system leads to reliable results in comminuted radial head fractures.
Crönlein M, Zyskowski M, Beirer M, Imhoff FB, Pförringer D, Sandmann GH, Kirchhoff C, Biberthaler P, Siebenlist S.

2017

Arch Orthop Trauma Surg.

This paper reports on 24 patients with a Mason III-IV radial head fracture, managed with a Medartis APTUS 2.0 Trilock Radial Head plates. The authors conclude that: " The treatment of comminuted radial head fractures using anatomically preshaped locking radial head plates represents a reliable and safe surgical approach, leading to good to excellent functional results."
