ICARA® Radial Head System

Concept

The completely new concept of the ICARA® Radial Head System allows the intraoperative adjustment of the joint tension. With the modular head component, consisting of three parts, the neck length can be adjusted by up to 5mm continuously to restore function and joint stability.

Head components

There are two diameters of head available (19mm and 22mm) which are connected to the stems by a polyethylene snap-locking mechanism.
The centre of rotation of the double inverse prosthesis is located at the level of the radial tuberosity. The prosthesis is self-centering to minimise the potential for malpositioning. The head can swing from neutral to -24° and to +24°.

Stem components

The system includes three different types of stem components with different collar sizes to adapt the system to the different size of bone defect or loss. The type S collar is 2mm thick, type 1 collar is 3.5mm thick and the type 2 collar has a thickness of 7.5mm. The minimal resection for type S is only 17.5mm. The stem components are available in cementless and cemented versions each in length 35mm and 50mm and in diameters of 6 and 8mm.
