Overview
The objective of this study is to analyse the positioning of the scapula in standing position and compared to the supine position (CT scan) in 3 dimensions (3 rotations of the scapula) using a non-radiant, portable system, combining an ultrasound probe with marker and a camera integrated into a Tablet for the three-dimensional location of the marker (probe).
Description
This is a mono-center trial. Patients in the process of pre-operative care of a reverse shoulder arthroplasty (CT Scan already available as part of the care course in supine position) will be offered the study. A localizer ultrasound will be performed during surgical consultation or the day before the surgery in standing position (duration: 1/2 day). This consultation takes place during the course of the surgical consultation or when the patient is admitted the day before his surgical procedure.
