Details and patient eligibility


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. * SF-12 Physical and Mental Health Summary Measures (SF12 Questionnaire) comprising of twelve questions to assess the subject's physical and mental health status which must be answered by the patient.

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.
