Multidirectional instability of the shoulder (MDI) is a clinical condition in which there is a dislocation of the shoulder in more than one direction, without a history of trauma or accompanied by a minimal trauma. Multidirectional instability has a complex pathoanatomy. It is characterized by a redundant glenohumeral capsule and increased joint volume. Subtle clinical presentation, unclear trauma history and multifactorial etiology pose a great challenge for orthopedics and traumatology surgeons in terms of diagnosis. Generally accepted therapeutic approach is conservative and the majority of patients achieve good results with rehabilitation. However, in patients who are symptomatic despite appropriate rehabilitation, surgical intervention may be necessary. Good results have been obtained with open inferior capsular shift surgery, which has historically been performed in these patients. However, in recent years, advanced arthroscopic techniques have taken place in this field, and similar results compared to open surgery have been obtained with the less invasive arthroscopic capsular plication procedure, which is applied in cases that do not respond to rehabilitation.
