Flashcards

What is the MCL?

The medial collateral ligament (MCL) is a key stabilizer of the elbow joint, preventing excessive sideways movements.

What is the common mechanism for an elbow dislocation?

A fall onto an outstretched hand with the shoulder abducted, resulting in a rotatory force that dislocates the elbow joint.

What is the main blood vessel that could be affected in an elbow dislocation?

The brachial artery is the main blood vessel supplying the arm, and can be damaged in an elbow dislocation, leading to potential complications like reduced blood flow.

What other types of injuries can occur alongside an elbow dislocation?

A fracture of the bones around the elbow can accompany a dislocation, often requiring surgical repair.

How do ligaments get damaged in an elbow dislocation?

The ligaments surrounding the elbow joint can be stretched or torn due to excessive force, affecting stability and potentially requiring surgery.

How is an elbow dislocation treated?

Following an elbow dislocation, the joint is manipulated and straightened, sometimes requiring surgery to repair damaged structures.

Elbow Joint Dislocation

Anatomy: Dislocation can cause damage to the ligaments around the elbow.
Mechanism of Injury: Rotatory forces, abduction of the shoulder, axial compression, supination of the forearm, or forced flexion of the elbow can lead to this. These forces can result in damage to the medial collateral ligament (MCL) and lateral collateral ligament (LCL).

Predisposing Factors for Elbow Joint Dislocation

Trauma: Direct impact or force is a significant factor.
Overuse: Prolonged repetitive stress can weaken connective tissues.
Age: Individuals under 16 or over 65 are more susceptible.
Previous Injury: A history of prior elbow injuries increases the risk.
Genetics: Predisposition towards certain conditions can affect the risk.

Treatment and Rehabilitation: Elbow Joint Dislocation

Reduction: Positioning the elbow at 45 degrees and using the humerus and wrist to guide the forearm into alignment. Radiography is performed for evaluation. Surgery is required in more severe cases.
Repair: Using a brace or splint to hold the elbow in a pronated position while the ligaments heal. Exercises to improve range of motion (ROM), strength (biceps, triceps muscle strengthening), and stability are included.

Elbow Joint Dislocation: Blood Vessels and Bones

Blood Vessels: The brachial artery is a significant blood vessel in the upper arm which is affected in this injury.
Bones: The humerus, radius, and ulna are bones of the elbow area.
Tendons: Injuries can affect the tendons of important muscles such as the biceps and triceps.
