The glenohumeral joint has the highest rate of dislocation of the whole body, due to its high mobility and the special characteristics of its anatomy. It is estimated that every year between 1-2% of the population will suffer from glenohumeral dislocation. The vast majority of studies are based on young patients under the age of 40, given that at this age they have the higher incidence and at the same time, they have higher redislocation index. However, the investigators are in front of a more active population with a longer life expectancy. That is why the cases of anterior glenohumeral dislocations are increasing in people older than 40 years. Given that most studies focus on younger patients, the investigators lack knowledge about which injuries are associated with dislocation at this age and whether these influence its clinical evolution.
