Outcome measures
Primary outcome
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 outcome
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.
Background summary
Anterior shoulder dislocations are a very common problem in the general
population and are often accompanied by damage to the glenohumeral capsule and
glenohumeral bony structures. Prognostic factors that have been reported for
recurrence after an acute first-time shoulder dislocation include age and
participation in sports, primarily collision sports and sport containing
overhead activities. In young patients, these prognostic factors contribute to
a reported recurrence up to 96%. Recurence contributes to additional damage to
soft tissue and glenohumeral bony structures, which could lead to apprehension.
Furthermore, patients are limited in daily activites and sports and (frequent)
recurrences involve high social costs.
Study objective
The primary objective is 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 CT scanning. Secondly, the degree of instability will be
correlated with clinical tests used in daily practice.
A separate objective is to investigate whether the BoneMRI technology can be
used for accurate 3D visualization of radiodensity (CT) contrasts in the
shoulder.
Study design
Cross-sectional study.
Study burden and risks
Patients will be exposed to radiation. However the exposure is minimal and
qualifies as a minor risk. This study aims no direct therapeutic effects for
the participants. However, the benefits are a better insight in the prognosis
and adequate information for the patients. In the long term, the benefits are
improved diagnostic imaging tools and a better insight in shoulder kinematics
and a better diagnosis of shoulder instability.

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.
