Summary

Open and arthroscopic Latarjet procedures are used to treat shoulder instability as primary and salvage procedures. During surgery the coracoid process is detached and repositioned to the anterior glenoid through a subscapularis split and fixed in place, resulting in an enlarged glenoid and therefor articular surface. However, before this is done, the pectorals minor, which inserts at the coracoid process, has to be detached and is left without further treatment. Moreover, the conjoint tendon, the origin of the short head of the biceps and coracobrachialis, is repositioned with the coracoid and therefor distalized and medialized. No study currently followed up on the strength of the muscles altered. The aim of this study is therefor, to prospectively measure range of motion and strength of the operated shoulder at different time points pre- and postoperatively, comparing it with the healthy shoulder in each individual.

Detailed description

Strength, range of motion and stability will be assessed pre-operatively and at 6 weeks, 12 weeks, 6 months, 12 months and 24 months post-operatively. Next to standard radiological follow up, including X-ray, arthrographic computed tomography as well as arthrographic magnetic resonance imaging, specific shoulder scores will be utilised. Strength for general shoulder motion as well as specifically for the subscapularis, the pectorals minor, the coracobrachialis and the biceps will be measured with a shoulder dynamometer. Data will be analysed and published.

Interventions

Type	Name	Description
OTHER	Strength testing before and after arthroscopic Latarjet	After patients, based on the ISI-Score, were assigned to treat their shoulder instability with an arthroscopic Latarjet procedure, they are eligible for this study. Strength of different involved muscles, as well as ROM will be measured before and at several time points after surgery.
