Lip Acetabular

The acetabular lip is an anatomical structure located on the inner surface of the acetabulum (fossa) of the hip joint. It plays an important role in the stability and functionality of the hip joint and can be damaged by injury or disease.

The acetabular labrum consists of two main components - the labrum and the articular disc. The labrum is a cartilaginous tissue that covers the fossa of the acetabular joint, and the articular disc is a fibrocartilaginous structure that separates the fossa into two parts.

The labrum plays an important role in protecting the joint from damage and ensuring its stability. It is also involved in the formation of synovial fluid, which serves as a lubricant for joints.

Injuries to the acetabular labrum can occur with injuries to the hip joint, such as fractures, dislocations, or torn ligaments. In such cases, surgery may be required to restore the integrity of the lip.

In addition, the acetabular labrum can be susceptible to diseases such as arthrosis, which causes it to thin and lose function. This can lead to disruption of the stability of the hip joint and the development of pain.

Thus, the acetabular labrum is an important anatomical structure that plays a key role in the functioning of the hip joint. Damage and disease can lead to disruption of its function and the development of complications. Therefore, it is important to monitor the health of the hip joint and undergo regular examinations with a doctor.

The name of this biological term comes from the Latin labrum - folds, lips. labra acetabularia - folded lips of the acetabulum. Sometimes the name “femoral lip” is used.

This article is dedicated to those who are planning surgery related to the removal of this anatomical structure (lateral lip of the acetabulum). What is it for? How is removal carried out and how can it end and when is such an operation necessary?

One of the common lesions in the hip joint is the development of aseptic necrosis of the femoral head, which subsequently leads to the development of coxarthrosis and osteochondropathy of the femoral head (Keller disease 2). In this case, bone tissue dies and foci of dead cartilage (bone cysts) form. A bone spur develops by replacing dead tissue. A spur larger than 5 mm is an indication for surgical treatment. The operation is not radical; the lateral edge of the femoral head is often damaged again. In turn, defects in the apex of the femoral head can lead to rapid progression of the disease. The lateral labrum of the trochanteris is often abducted partially or completely using muscle and tendon structures. The method is quite simple to perform, since the operation process is based on the restoration of damaged structures of the femoral head. As is known, with coxartosis, pathological processes develop on the surface of the acetabular cup and the femoral component of the joint. Both of these cups are hemispheres, their edges touch and form the axial line of the femoral neck, where there is a certain continuity. The wide cavity of the trochanter is a depression between the ends of the articular surfaces. The mount of the swivel is the apex of the semium

The acetabular labrum is an important anatomical element that is located between the thigh and pelvis, and is part of the synovial lip or external capsule of the hip joint. It plays an important role in stabilizing the joint and protecting it from damage.

The acetabular lip makes up approximately 25% of the area of ​​the inner surface of the hip joint and is formed by two layers of fascia: the acetabular leaf and the pelvic layer. The fascia of the acetabular edges has a triangular shape, and the pelvic layer forms two spinous and two arcuate parts.

The acetabular lip is covered with adipose tissue and contains a large number of blood vessels and nerve endings. It also provides a mechanism for connecting bone and cartilage and prevents damage to bones.
