About

The purpose of this study is to obtain outcomes data on the Anatomical Shoulder™ Inverse/Reverse System by analysis of standard scoring systems and radiographs.

Outcome data will be collected using the following standard scoring systems of which summary statistics will be provided:

• Constant and Murley Score to evaluate clinical parameters such as range of motion, power, level of pain and functional ability.

Full description

This is a multi-centre, non-comparative, prospective post-market surveillance study involving orthopaedic surgeons skilled in shoulder replacement surgery. Each case enrolled will receive an Anatomical Shoulder™ Inverse/Reverse implant. All system components are CE-marked and commercially available. Patients will be selected according to the subject selection criteria.

All patients will undergo pre-operative, intra-operative and post-operative physical examination, radiographic evaluation according to the hospital's routine procedure and collection of quality of life metrics. Follow-up evaluations are to be conducted at either 6 weeks or 6 months (according to the hospital's standard care plan) and thereafter at 1, 2, 5 and 10 years post hospital discharge.

There are 5 study centres taking part in this project enrolling in total a maximum of 160 patients.
