Study summary

Anterior shoulder instability is a chronic condition that occurs after an anteromedial dislocation. Its prevalence is high in athletes but has been little studied in the armed forces. In general, patients with a first episode of dislocation have a 1 in 2 chance of experiencing at least one recurrence. The more recurrences there are, the more damage there is to the joint and the greater the disability for the patient. The decree determining the medical aptitude of military personnel emphasizes the need to have recourse to a specialized consultation to determine the classification of the soldier after a first episode of dislocation. In the absence of data collected specifically in the military population, classification is based on the surgeon's experience and extrapolation of results obtained in the general population.

What researchers measure

Primary outcomes

  1. Percentage of patients with a new episode of true anterior glenohumeral shoulder dislocation or subluxation 1 year after the initial dislocation.

    A true anterior glenohumeral shoulder dislocation is defined as a dislocation requiring reduction. Dislocation and subluxation will have to be objectified by medical examination

    Time frame: Through study completion (72 months)
