What is the structure of the acetabular labrum?
The acetabular labrum is a soft tissue of the hip joint attached to the acetabular rim. Together with the transverse acetabular ligament, the two structures join inferiorly to form a continuous ring.
What is acetabulum labrum?
The labrum is a band of tough cartilage and connective tissue that lines the rim of the hip socket, or acetabulum. It cushions the joint of the hip bone, preventing the bones from directly rubbing against each other.
What is the role of the acetabular labrum?
In normal hip joint biomechanics, the labrum is crucial in retaining a layer of pressurised intra-articular fluid for joint lubrication and load support/distribution. Its seal around the femoral head is further regarded as a contributing to hip stability through its suction effect.
What is the acetabular labrum and what is its function?
The hip labrum is a gasket-like structure that lines the periphery of the acetabulum, or socket of the hip joint. Like the gaskets that seal the joints between the pipes in your house, the acetabular labrum provides a suction seal for your hip joint — adding to the stability to the joint.
What is labrum in anatomy?
What is the labrum? The labrum is a type of cartilage found in the shoulder joint. The shoulder is a ball-and-socket joint where the arm meets the body. The arm bone (humerus) forms a ball at the shoulder that meets the socket, which is part of the shoulder blade.
What is the difference between labral and labrum?
The labrum is a piece of fibrocartilage (rubbery tissue) attached to the rim of the shoulder socket that helps keep the ball of the joint in place. When this cartilage is torn, it is called a labral tear. Labral tears may result from injury, or sometimes as part of the aging process.
What are the symptoms of a torn labrum?
The symptoms of a sports-related labral tear in the shoulder can include:
- Pain when doing overhead activities.
- Grinding, popping, “sticking” in the shoulder socket.
- Pain at night.
- Decreased range of motion in the shoulder.
- Loss of shoulder strength.
How do you treat a frayed hip labrum?
Labral Fraying. Generally, fraying affects a specific area of the labrum. For example, wear and tear from frequent kicking or dancing may cause a few centimeters of the labrum to fray. This damage may be treated with a surgery called debridement to smooth the damaged piece of the labrum.
What is labrum and its function?
The labrum is a thick tissue or type of cartilage that is attached to the rim of the socket and essentially forms a bumper that deepens the socket and helps keep the ball in place.
What is the function of the fovea capitis?
The fovea capitis is the pit on the head of the femur where the ligamentum teres inserts. This ligament holds the femur in the hip socket.
Does a hip labral tear cause arthritis?
The labrum also helps to keep the ball from slipping out of the socket. A hip labral tear is damage to the labrum in the hip. That damage can lead to hip pain, damage to the bones in the joint, and arthritis in the joint.
What is a labrum in hip?
A hip labral tear involves the ring of cartilage (labrum) that follows the outside rim of your hip joint socket. Besides cushioning the hip joint, the labrum acts like a rubber seal or gasket to help hold the ball at the top of your thighbone securely within your hip socket.
