Angle of inclination

The angle in the frontal plane that measures the relationship between the femoral shaft and the neck of the femur; normal is 125 degrees, less than 125 degrees is Coxa Vara, and greater than 125 degrees is Coxa Valga.

Femoral Torsion Angle

The angle in the transverse plane measuring the rotation of the femoral neck; normal/anteversion is 15 degrees, excessive anteversion is greater than 15 degrees, and retroversion is less than 15 degrees.

Center Edge Angle

An angle in the frontal plane that indicates the extent to which the acetabulum covers the femoral head; normal range is 35-40 degrees.

Acetabular Anteversion Angle

An angle in the transverse plane; normal is 20 degrees.

Iliofemoral ligament

A main ligament of the hip that becomes taut with full extension and external rotation.

Pubofemoral ligament

A ligament that gets taut with extreme extension and abduction of the hip.

Ischiofemoral Superficial ligament

A ligament that is taut with full internal rotation and extension of the hip.

Ischiofemoral Deep ligament

A ligament that is taut with hip flexion.

Ligamentum Teres

A ligament located in the fovea of the femur, providing minimal stability and housing a small artery.

Transverse Acetabular Ligament

A ligament that spans the acetabular notch.

Open chain movements of the hip

Movements where the head of the femur moves on the acetabulum.

Closed chain movements of the hip

Movements where the pelvis moves over a relatively fixed femoral head.

Posterior pelvic tilt

A pelvic movement performed by activating the hip extensors and core muscles.

Anterior pelvic tilt

A pelvic movement performed by activating the hip flexors and back extensors.
