Summary
Bilateral posterior shoulder dislocation is a rare complication following seizures. This case highlights how it can mimic other conditions, emphasizing the need for careful diagnosis after seizure activity.
Area of Science:
- Orthopedics
- Neurology
- Emergency Medicine
Background:
- Seizure activity can lead to various musculoskeletal complications.
- Posterior shoulder dislocation is an uncommon but serious sequela.
Observation:
- A patient presented with bilateral upper extremity blood pressure discrepancies post-seizure.
- Initial presentation suggested alternative clinical diagnoses.
Findings:
- The patient was diagnosed with bilateral posterior shoulder dislocations.
- This occurred following his first-ever seizure episode.
Implications:
- Clinicians should consider posterior shoulder dislocations in patients with neurological events and upper extremity symptoms.
- Prompt recognition and management are crucial to prevent long-term morbidity.

01:23Muscles of the Shoulder
The muscles surrounding the shoulder girdle, including the clavicle and scapula, primarily stabilize the scapula. This stable base allows other muscles to move the humerus effectively. Scapular movements often mirror those of the humerus and extend its range of motion. For instance, raising the arm above the head would not be feasible without simultaneous upward rotation of the scapula.

01:31Muscles that Move the Arm
Nine muscles are involved in arm movements. Two of these, the pectoralis major and latissimus dorsi, originate from the axial skeleton and are called axial muscles. The other seven originate from the scapula and are called the scapular muscles.
The pectoralis major has two origins. Its clavicular head originates on the medial half of the clavicle. In contrast, the sternocostal head originates on the costal cartilages of ribs 1-6, the sternum, and the aponeurosis of the external oblique of the...
