BackgroundTraumatic anterior shoulder dislocation is the most common type of joint dislocation, with an incidence of 11 to 29 per 100 000 persons per year. Controversy still surrounds the recommendations for treatment and the available procedures for surgical stabilization.MethodsThis review is based on pertinent publications (2014-2024) that were retrieved by a selective search in the PubMed and Google Scholar databases. Meta-analyses and randomized controlled trials (RCTs) with evidence levels I and II were included.ResultsThe typical injury mechanism is forcible external rotation and abduction of the arm. The diagnosis is established by x-ray, which may be supplemented by magnetic resonance imaging (MRI) for the assessment of soft-tissue structures. The indication and type of surgical treatment depends on the patient's age, sex, activity level, and concomitant injuries. For purely soft-tissue injuries, arthroscopic Bankart repair is an established treatment, with reported significant reduction in the rate of recurrent instability after follow-up periods of up to 12 years. An accompanying bony injury of the dorsal humeral head (Hill-Sachs lesion), depending on its extent, may be an indication for the arthroscopic Remplissage procedure: this can lower the rate of recurrence, but it can also cause a postoperative restriction of external rotation. In cases of chronic instability, an arthroscopic or open Latarjet procedure and bone grafting can be performed to augment the ventral glenoid articular surface. These procedures have likewise been reported to yield low rates of recurrent instability, but also higher complication rates.ConclusionThe treatment of shoulder dislocation should be individually tailored. Although the reported results are promising, the evidence base remains weak. Prospective studies with larger case numbers are needed so that clear treatment algorithms can be established.
