Inclusion criteria
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
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.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| To quantify the degree of shoulder instability by determining the contact surface area between the glenoid and the humerus together with the translation of the humeral head during motion using three-dimensional radiographic scanning. A separate objective is to investigate whether the BoneMRI technology can be used for accurate 3D visualization of radiodensity (CT) contrasts in the shoulder. | — |
Secondary
| Measure | Time frame |
|---|---|
| To link the objectively obtained parameters with measurements used in daily practise. The apprehension and relocation test will be performed to determine the correlation of the parameters with a positive test. Furthermore, cartilage thickness between glenoid and humeral head will be estimated and the volume and shape of the humerus during motion will be determined. | — |
