What is the likely injury for someone presenting with shoulder pain after a seizure or electrical shock?

• A. Fracture of the clavicle
• B. Posterior shoulder dislocation
• C. Rotator cuff tear
• D. Anterior shoulder dislocation

Answer: (B)

When a person presents with shoulder pain after experiencing a seizure or electrical shock, the most likely injury is a posterior shoulder dislocation. This type of injury can occur due to the intense muscle contractions and abnormal body movements associated with seizures or electrical shocks.

During a seizure, the involuntary muscle contractions can result in the arm being forced into an abnormal position, particularly leading to a posterior shoulder dislocation. This dislocation is often overlooked since most shoulder dislocations are anterior; however, in the context of seizures, the muscle spasm can push the humeral head posteriorly relative to the glenoid cavity.

Recognizing posterior shoulder dislocation is crucial, as it may not present with the typical signs seen in anterior dislocations, and can potentially lead to complications if not diagnosed and treated promptly.
