About this trial
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).

Trial outcomes
Primary outcomes
1
Study the location of the scapula in 3 dimensions for the patient in standing position
descriptive statistics of the population : mean and standard deviation of the 3 rotations of the scapula in each plane of reference coronal plane expressed in degree. Comparison with the supine position and analysis of any differences.
Time frame
Day 12
Study the location of the scapula in 3 dimensions for the patient in standing position
descriptive statistics of the population : mean and standard deviation of the 3 rotations of the scapula in each plane of reference axial plane expressed in degree. Comparison with the supine position and analysis of any differences.
Time frame
Day13
Study the location of the scapula in 3 dimensions for the patient in standing position
descriptive statistics of the population : mean and standard deviation of the 3 rotations of the scapula in each plane of reference sagittal plane expressed in degree. Comparison with the supine position and analysis of any differences.
Time frame
Day 1Secondary outcomes
1
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
