What are the gluteal lines on the ilium?

What are the gluteal lines on the ilium?

The posterior, the anterior, or the inferior gluteal line, which are bony ridges on the posterior (exterior) surface of the ilium parallel to the iliac crest. The posterior gluteal line runs along the outer edge of the iliac crest and marks the upper edge of the origin of the gluteus medius muscle.

What attaches to gluteal lines?

Gluteal Muscles (Figure 35-1B) Attaches proximally on the ilium behind the posterior gluteal line, the sacrum, the coccyx, and the sacrotuberous ligament; distally, the muscle attaches at the iliotibial tract and the gluteal tuberosity of the femur.

What is the anterior gluteal line?

The anterior gluteal line (middle curved line), the longest of the three lines on the gluteal surface of ala of ilium, begins at the crest, about 4 cm. behind its anterior extremity, and, taking a curved direction downward and backward, ends at the upper part of the greater sciatic notch.

Is the gluteal part of the hip?

Gluteal muscles, located on the back of the hip (buttocks) The adductor muscles on the inner thigh bring the leg back to the center when out to the side.

What are the 3 gluteal lines?

The gluteal lines are three curved lines outlined from three bony ridges on the exterior surface of the ilium in the gluteal region. They are the anterior gluteal line; the inferior gluteal line, and the posterior gluteal line.

What is the function of the gluteal lines?

The main functions of the gluteus maximus muscle are the extension and external rotation of the thigh at the hip joint. Additionally, its superior part can produce thigh abduction, while the inferior part causes the thigh adduction.

What is gluteal tuberosity?

The gluteal tuberosity (or line, crest, or ridge) is a long, wide, roughened, posterolaterally placed feature that extends from the base of the greater trochanter to the lateral lip of the linea aspera (see 12.1.

Is the gluteal tuberosity site of muscle attachment?

The gluteal tuberosity is the lateral ridge above the linea aspera of the femur. It is the site of insertion of the gluteus maximus muscle.

What causes gluteus medius trigger points?

Such pain most often occurs as a result of repetitive microtrauma to the muscle from activities such as running on soft surfaces and overuse of exercise equipment or other repetitive activities that require hip abduction (Figure 85-1). Blunt trauma to the muscle may also incite gluteus medius myofascial pain syndrome.

Where is the gluteal tuberosity?

How many gluteal lines are there?

three
The gluteal lines are three curved lines outlined from three bony ridges on the exterior surface of the ilium in the gluteal region. They are the anterior gluteal line; the inferior gluteal line, and the posterior gluteal line.

Where does the gluteus maximus attach to the femur?

Attaches proximally on the ilium behind the posterior gluteal line, the sacrum, the coccyx, and the sacrotuberous ligament; distally, the muscle attaches at the iliotibial tract and the gluteal tuberosity of the femur. The gluteus maximus muscle is a powerful extensor of a flexed femur at the hip joint and a lateral stabilizer of the hip joint.

What are the muscles of the gluteal region?

Muscles of the gluteal region primarily act on the hip joint. The hip joint is a synovial, ball-and-socket joint. The “ball” is the head of the femur, and the “socket” is the acetabulum of the pelvic bone. The motions of the hip joint are as follows ( Figure 35-1A ): Flexion. Movement anterior in the sagittal plane. Extension.

What is the function of the gluteal bone?

The bones of the gluteal region contain foramina (notches), which serve as conduits for nerves and blood vessels that travel between the pelvis, gluteal region, perineum, and lower limb. Muscles of the gluteal region primarily act on the hip joint. The hip joint is a synovial, ball-and-socket joint.

What are the bony landmarks of the pelvis?

Bony Landmarks of the Pelvis/Coxa Ilium Sacroiliac joint Iliac crest Sacrum: pelvic surface Iliac fossa Sacrum: lateral part Anterior superior iliac spine (ASIS) Sacral canal Anterior inferior iliac spine (AIIS) Posterior sacral foramins
