Scapular Positioning in Standing Position Using Sonography
Scapular Positioning in Standing Position Using Sonography
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).
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.
