COVID-19 studies are our top priority. For all other trials, there is a 4-week delay in processing a trial submitted to the ANZCTR and additional delays for updates of registered trials. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Study type
Description of intervention(s) / exposure
PROMOS standard prosthesis- The standard PROMOS features modular components for the metaphyseal part, the collum (modular body) and the humeral head. The body (metaphyseal component) in different heights helps to restore the original length of the humerus und can be fixed in any antetorsion angle.
PROMOS reverse prosthesis - The reverse shoulder system consists of a humeral and a glenoid component, both of which are modular. The humeral stem is used in combination with a body and concave polyethylene component. The concave polyethylene component snaps into the proximal body and articulates with the
hemispherical head attached to the glenoid baseplate. The glenoid baseplate is fixed in the glenoid bone with two screws.

The appropriate treatment type is administered to patients based on individual requirements as determined by the operating surgeon

The duration of the surgical procedure depends on individual circumstances, on an average a normal surgey lasts for 1.5 hours.
