A shoulder dislocation occurs when the upper arm bone
(humerus) pops out of the shoulder socket (glenoid). This injury is often the result of a
significant force or trauma to the shoulder. Shoulder dislocations are relatively common, and
they can be painful and disabling. There are different types of shoulder dislocations, including
anterior, posterior, and inferior dislocations.
Anterior Shoulder Dislocation :
- Description: The humerus is displaced forward, out of the front of the
shoulder socket.
- Causes: Typically occurs due to a force that pushes the arm backward when
it is raised.
Posterior Shoulder Dislocation :
- Description: The humerus is displaced backward, out of the back of the
shoulder socket.
-
Causes: Uncommon and often associated with specific traumatic events, such
as seizures or electric shock.
Inferior Shoulder Dislocation (Luxatio Erecta):
- Description: The humerus is displaced downward, below the shoulder socket.
-
Causes: Uncommon, usually occurring in a unique and forceful position.
Symptoms of Shoulder Dislocation:
- Pain: Sudden and severe pain in the shoulder.
- Weakness: Swelling and bruising around the shoulder joint.
- Deformity: The shape of the shoulder may look abnormal.
- Limited Movement: Inability to move the arm or significant pain with movement.
