How do you describe an elbow dislocation?
An elbow dislocation occurs when the bones of the forearm (the radius and ulna) move out of place compared with the bone of the upper arm (the humerus). The elbow joint, formed where these 3 bones meet, becomes dislocated, or out of joint.
What causes elbow dislocation?
Elbow dislocation occurs when the humerus, ulna and radius (the elbow bones) move out of place where they meet at the elbow joint. This usually occurs when an individual breaks a fall with an outstretched hand while the arm is held straight.
What is the dislocation of the elbow called?
When the elbow joint is partially dislocated, it is called a subluxation. Doctors also classify elbow dislocations according to the extent of the damage and where it occurs. The 3 types include: Simple: No major injury to the bone.
What structures are involved in elbow dislocation?
The most common neurovascular structures injured during an elbow dislocation include the brachial artery and the ulnar and median nerves. Perfusion can be assessed by palpating the radial and ulnar pulses and looking for a brisk capillary refill.
What type of joint is the elbow?
hinge joint
Normal Anatomy of the Elbow. The arm in the human body is made up of three bones that join together to form a hinge joint called the elbow. The upper arm bone or humerus connects from the shoulder to the elbow forming the top of the hinge joint.
What muscles are involved in elbow dislocation?
Injured structures include the anterior and posterior bands of the medial and lateral collateral ligaments of the elbow, along with, at times, the brachialis muscle, the flexor-pronator muscle group, and articular cartilage.
What is the treatment for elbow dislocation?
Simple elbow dislocations are treated by keeping the elbow immobile in a splint or sling for 1 to 3 weeks, followed by early motion exercises. If the elbow is kept immobile for a long time, the ability to move the elbow fully (range of motion) may be affected.
What muscles are affected in an elbow dislocation?
The LCL is often disrupted when an elbow dislocation occurs; the MCL is the last soft tissue structure injured as the ulna is displaced. Often, the flexor-pronator mass may be ruptured, and occasionally the brachialis may be injured.
What is elbow called?
Technically, you can refer to the area as the antecubital fossa. Antecubital is an adjective meaning “of or relating to the inner or front surface of the forearm” (in Latin ante means “before” and cubitum means “elbow”). Fossa is a Medieval Latin borrowing that is used for an anatomical pit, groove, or depression.
What is the function of elbow?
The function of the elbow joint is to extend and flex the arm grasp and reach for objects. The range of movement in the elbow is from 0 degrees of elbow extension to 150 degrees of elbow flexion.
What type of joint is elbow?
Normal Anatomy of the Elbow. The arm in the human body is made up of three bones that join together to form a hinge joint called the elbow. The upper arm bone or humerus connects from the shoulder to the elbow forming the top of the hinge joint.
What is the type of elbow?
The elbow joint is classified structurally as a synovial joint. It is also classified structurally as a compound joint, as there are two articulations in the joint. Synovial joints, also called diarthroses, are free movable joints….Elbow joint.

How elbow joint is formed?
The elbow consists of three joints from articulation of the three bones namely: Humeroulnar joint is formed between the humerus and ulna and allows flexion and extension of the arm. Humeroradial joint is formed between the radius and humerus, and allows movements like flexion, extension, supination and pronation.
