What is a common complication associated with a posterior dislocation of the shoulder?

A common complication associated with a posterior dislocation of the shoulder is seizures. This occurrence is often linked to specific circumstances under which the dislocation happens, such as electrical injuries or severe trauma, where the impact or stress on the body may lead to convulsions. Posterior dislocations are also less common than anterior dislocations and can be more insidious, often going unrecognized in clinical presentations.

While neurovascular injuries are a concern with shoulder dislocations, they are more frequently associated with anterior dislocations. Other complications, such as rotator cuff tears and fractures of the humerus, can occur but are not as specifically associated with posterior dislocations as seizures can be. Therefore, recognizing the relationship between posterior dislocation and potential seizures helps in understanding the broader implications of such injuries.
