Acetabular labrum
|
|
Acetabular labrum"A ring of fibrocartilage (fibrous cartilage) that runs around the acetabulum (cup) of the hip joint and increases its depth. The head of the femur (the bone in the thigh) fits in the acetabulum. The labrum deepens this cavity and effectively increases the surface (and strength) of the hip joint. Injuries to the acetabular labrum can occur from chronic trauma due to repetitive hip motion or from acute trauma as, for example, from a direct blow to the hip or a violent motion of the hip. Signs and symptoms of a acetabular labrum injury include pain accompanying hip motion, occasional pain in the hip at night or during daily activities, decreased range of motion and loss of strength in the hip. Treatment may include anti-inflammatory medication and rest. Exercises to strengthen the hip muscles may then be recommended. If these measures are not effective, arthroscopic surgery may be done. In medicine, a labrum is a ring of fibrocartilage around the edge of the articular (joint) surface of a bone. The Latin ""labrum"" means ""lip."" The term is used generally to designate a lip, edge, or brim. Plural, labra."
RELATED TERMS--------------------------------------
Acetabulum
"The cup-shaped socket of the hip joint. In fact, in Latin an ""acetabulum"" is cup, a vinegar cup. The acetabulum is a feature of the pelvis. The head (upper end) of the femur (the thighbone) fits into the acetabulum and articulates with it, forming a ball-and-socket joint."
Joint
Where the ends of two or more bones meet.
Femur
The thigh bone.
Bone
Bone refers either to a hardened connective tissue or to one of the individual structures, or organs, into which it is formed, found in many animals. Bones support body structures, protect internal organs, and (in conjunction with muscles) facilitate movement; are also involved with cell formation, calcium metabolism, and mineral storage. The bones of an animal are, collectively, known as the skeleton.
Cavity
A hollow place or hole within the body.
Acetabular
"Pertaining to the acetabulum, the cup-shaped socket of the hip joint which is a key feature of the pelvis. The head (upper end) of the femur (the thighbone) fits into the acetabulum and articulates with it, forming a ball-and-socket joint. The acetabulum is not just cup-shaped. The word ""acetabulum"" in Latin means cup, a vinegar cup."
Chronic
Ongoing or recurring. Chronic medical conditions include diabetes, epilepsy, and chronic fatigue syndrome.
Trauma
Injury caused by external force, chemical, temperature extremes, or poor tooth alignment.
Acute
1. Of short course. 2. Severe, but of a short duration. Not chronic.
Hip
The region on each side of the pelvis made up of three sections: ilium, ischium, and pubis. The upper part of the femur (upper leg bone) fits into the hip via a ball-and-socket joint. The socket is a cup-shaped bone of the pelvis called the acetabulum and the ball is the head of the femur.
Injury
Injury is damage or harm caused to the structure or function of the body caused by an outside agent or force, which may be physical or chemical.
Pain
An unpleasant sensory or emotional experience primarily associated with tissue damage, or described in terms of tissue damage, or both.
Arthroscopic
"Refers to a surgical technique whereby a doctor inserts a tube-like instrument into a joint to inspect, diagnose and repair tissues. It is most commonly performed in patients with diseases of the knees or shoulders. The word arthroscopic is often confused with orthoscopic. Orthoscopic means having correct vision or producing it. Orthoscopic, in other words, means free from optical distortion or designed to correct distorted vision. This fits with the prefix ""ortho-"", meaning straight or erect, and with ""-scopic"" from the Greek ""skopein"", to see. Orthoscopic literally is to see straight. Knee surgery performed with a small scope is arthroscopic knee surgery, not orthoscopic knee surgery."
Surgery
Treating diseases or other medical conditions by operating on a patient to remove or repair parts of the body.
