Details and patient eligibility

About

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).

Full 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.

Enrollment: 30 estimated patients

Sex: All

Ages: 18 to 99 years old

Volunteers: No Healthy Volunteers

shoulder localizer ultrasound

Experimental group

Description:

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.
