Recruitment & Eligibility

Status: Withdrawn

Sex: Not specified

Target Recruitment: 15

Inclusion Criteria

Patients between the age of 18 and 50 years old that underwent recurrent
anterior shoulder dislocations (n * 2). Patients need to understand the Dutch
or English language to be able to sign the informed consent form.

Exclusion Criteria

Patients are excluded when they have experienced a posterior dislocation,
primary anterior shoulder dislocation or experienced a dislocation for any
other reason than trauma. Furthermore, shoulders containing rotator cuff
tears, previous surgery in the ipsi- or contralateral shoulder, a positive
sulcus sign or jerk test, a beighton score of > 2, significant osteoarthritis,
(pathologic) fractures or significant Hill-Sachs lesions will be excluded.

Study & Design

Study Type: Observational invasive

Study Design: Not specified

Primary Outcome Measures

Name	Time	Method
<p>To quantify the degree of shoulder instability by determining the contact<br /><br>surface area between the glenoid and the humerus together with the translation<br /><br>of the humeral head during motion using three-dimensional radiographic<br /><br>scanning.<br /><br><br /><br>A separate objective is to investigate whether the BoneMRI technology can be<br /><br>used for accurate 3D visualization of radiodensity (CT) contrasts in the<br /><br>shoulder.</p><br>

Secondary Outcome Measures

Name	Time	Method
<p>To link the objectively obtained parameters with measurements used in daily<br /><br>practise. The apprehension and relocation test will be performed to determine<br /><br>the correlation of the parameters with a positive test. Furthermore, cartilage<br /><br>thickness between glenoid and humeral head will be estimated and the volume and<br /><br>shape of the humerus during motion will be determined.</p><br>
