Joint dislocation
Joint Dislocation
Joint dislocation (/dɪs.ləʊˈkeɪ.ʃən/), also known as luxation, is a medical condition where the surfaces of a joint are forced apart, causing the bones that form the joint to lose contact with each other. This condition often results from a sudden impact to the joint, such as a fall or a blow during a physical activity.
Etymology
The term "dislocation" is derived from the Latin word "dislocare" which means "to put out of place". The term "luxation" comes from the Latin "luxare", meaning "to dislocate".
Types of Joint Dislocation
There are several types of joint dislocations, including:
- Shoulder dislocation: This is the most common type of joint dislocation, often caused by a strong force or extreme rotation of the shoulder.
- Elbow dislocation: This occurs when the bones that make up the elbow are forced out of alignment, usually as a result of a fall onto an outstretched hand.
- Knee dislocation: This is a rare but serious injury, often caused by high-energy impacts, such as car accidents or sports injuries.
- Hip dislocation: This is often the result of a high-energy event, such as a car accident or a fall from a significant height.
Symptoms
Symptoms of a joint dislocation can include intense pain, inability to move the joint, visible deformity of the joint, swelling, bruising, and numbness or tingling.
Treatment
Treatment for a joint dislocation often involves a procedure known as a reduction, where a healthcare professional manually moves the bones back into place. Following this, the joint is usually immobilized with a splint or cast. In some cases, surgery may be required to repair or stabilize the joint.
Related Terms
- Subluxation: This is a partial dislocation of a joint, where the joint surfaces remain partially in contact with each other.
- Fracture: This is a break in a bone, which can sometimes occur in conjunction with a dislocation.
