What is the function of ligamentum teres femoris?
It is composed of two bands that originate from the acetabular transverse ligament and the pubic and ischial margins of the acetabular notch. Among other functions, the ligamentum teres is an important stabilizer of the hip, particularly in adduction, flexion, and external rotation.
What is the importance of the ligamentum teres?
The ligamentum teres of the hip connects the femoral head to the acetabulum. It is an important in providing hip stability and supplies blood to the femoral head. Damage to the ligamentum teres is most often caused by traumatic injury or repetitive twisting movements.
What is ligamentum teres?
The ligamentum teres (LT) consists of two bands that originate on the ischial and pubic sides of the acetabular notch and insert on the fovea capitis of the femoral head. Recent studies have established the LT as an important hip stabilizer in a squatting position, particularly in patients with osseous instability.
Which ligament helps support the hip?
Iliofemoral ligament
Iliofemoral ligament – This is a Y-shaped ligament that connects the pelvis to the femoral head at the front of the joint. It helps in limiting over-extension of the hip. Pubofemoral ligament – This is a triangular shaped ligament that extends between the upper portion of the pubis and the iliofemoral ligament.
What is ligamentum teres a remnant of?
The ligamentum teres is the remnant of the umbilical vein working throughout fetal life. Initially a pair of the umbilical veins entered the sinus venosus.
What does the ligamentum venosum separate?
The ligamentum venosum courses along the visceral/posterior aspect of the liver in the fossa for ductus venosum, which separates the caudate lobe and the left lobe.
What does the ligamentum teres do?
This ligament connects the ball of the hip joint (femoral head) to the hip socket (acetabulum). Injuries to the ligamentum teres include complete tears, partial tears, and degenerative fraying. You may feel pain or a clicking sensation in your hip after a twisting injury, dislocation or subluxation of…

Can a torn ligamentum teres cause hip dislocation?
Although a torn ligamentum teres typically is associated with hip dislocation, partial or complete tears may occur in the setting of other joint stresses such as a flexion-adduction stress, which occurs when a patient falls on the ipsilateral knee with the hip flexed, or a sudden twisting injury (usually external rotation) of the hip ( 1, 2, 4 ).
What is the prevalence of ligamentum teres abnormalities?
Abnormalities of the ligamentum teres account for 4%–15% of sports-related injuries and should be considered in the differential diagnosis of patients with hip pain.
