What is dislocation and its types?
The number and arrangement of dislocations influences many of the properties of materials.

Examples of sessile dislocations are the stair-rod dislocation and the Lomer–Cottrell junction.
What is the most commonly dislocated joint in the body?
The shoulder joint is the most frequently dislocated joint of the body. Because it moves in several directions, your shoulder can dislocate forward, backward or downward. The most common variety is a forward (anterior) dislocation.
What is joint subluxation?
The place where two or more bones in the body come together is called a joint. A dislocation occurs when the bones in a joint become separated or knocked out of their usual positions. Any joint in the body can become dislocated. If the joint is partially dislocated, it is called a subluxation.
How do you put a joint back into place?
Popping the shoulder joint in yourself
- While standing or sitting, grab the wrist of your injured arm.
- Pull your arm forward and straight, in front of you. This is meant to guide the ball of your arm bone back to the shoulder socket.
- When the shoulder is back in place, put your arm in the sling.
What causes joints to pop out of place?
Joints naturally accrue nitrogen bubbles over time, because of the synovial fluid that serves as a lubricant for them. These bubbles can build up in the spaces of a joint, and cause the joint to feel tight. When this happens, you can “crack” the joint to loosen it, releasing the gas from it’s bubbles.
Why is the shoulder joint also called the glenohumeral joint?
The shoulder joint is formed by the articulation of the head of the humerus with the glenoid cavity (or fossa) of the scapula. This gives rise to the alternate name for the shoulder joint – the glenohumeral joint. Like most synovial joints, the articulating surfaces are covered with hyaline cartilage.
What is the glenohumeral joint?
Introduction. The glenohumeral joint is structurally a ball-and-socket joint and functionally is considered a diarthrodial, multiaxial, joint.

What are your shoulder muscles called?
The rotator cuff is an anatomical term given to the group of four muscles and their tendons that act to stabilize the shoulder. These muscles are the supraspinatus, infraspinatus, teres minor and subscapularis and that hold the head of the humerus in the glenoid cavity during movement.
Why do my shoulders hurt when I lift my arms?
Shoulder impingement is a very common cause of shoulder pain, where a tendon (band of tissue) inside your shoulder rubs or catches on nearby tissue and bone as you lift your arm. It affects the rotator cuff tendon, which is the rubbery tissue that connects the muscles around your shoulder joint to the top of your arm.
