Determination of Scapulothoracic and Glenohumeral Angles by Imaging in Patients After Shoulder Arthroplasty (SCAP-imag)

The EOS procedure will consist of taking 3 x-rays per side (6 in total) while the patient is standing (oriented at 35° to the x-ray) with the arm in position 0°, then at 45° and finally at 90° elevation in the frontal plane for 20 seconds per position.

There will be 2 questionnaires : Constant and American Shoulder and Elbow Surgeons to determine their pain level and functional limitations.
