About this study
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).
Read the detailed 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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Scapular positioning in Standing position using SonographyDiagnostic test
The localizer ultrasound of the shoulder is performed in an unclothed patient (at the shoulders) and comes to locate bony landmarks using the ultrasound probe as a Transcutaneous localizer.
| Study group | Role | What they receive |
|---|---|---|
| shoulder localizer ultrasound | Experimental | The localizer ultrasound of the shoulder is performed on an unclothed patient (at the shoulders) and comes to locate bony landmarks using the ultrasound probe as a Transcutaneous localizer. The Protocol plans to acquire different landmarks on the scapula: lower angle, coracoid, scapula spine and bilateral acromioclavicular joint (definition of the coronal plan). These acquisitions are carried out by the probe connected to a Tablet (Microsoft surface Pro 3) which allows to locate the probe and by extension of the probe the location of the points selected by ultrasound.

Secondary outcomes (3)
Evaluating the accuracy of the device using a validation bench
Validation of the device using a biomechanical bench. The rotation will be assessed in coronal plane in degree. The differences between the measurements of the biomechanical bench will be compared to the measurements validation bench to assess the mean error and standard deviation of the ultrasound device

Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
