Q

The iliofemoral ligament is a thick, triangular ligament that anteriorly covers the hip joint. Also known as the Y-ligament, this structure connects the ilium to the intertrochanteric line of the femur and prevents hyperextension of the hip.

The pubofemoral ligament is a triangular ligament anteroinferior to the hip joint. Connecting the pubic bone to the femur, this structure is critical in preventing excessive extension and abduction of the hip joint.

Q
A

The gastrocnemius is the most superficial of all the muscles in the posterior leg. It has medial and lateral heads and forms the characteristic “calf” shape of the leg.

The soleus is a flat muscle located underneath the gastrocnemius. It gets its name from its resemblance to a sole – a flat fish.

The plantaris is a small muscle which is absent in approximately 10% of the population.

There are three muscles within the superficial compartment of the posterior leg. They all insert onto the calcaneus (heel bone) of the foot, via the calcaneal tendon.

To minimise friction during movement, there are two bursae (fluid filled sacs) associated with the calcaneal tendon:

Subcutaneous calcaneal bursa – lies between the skin and the calcaneal tendon.
Deep bursa of the calcaneal tendon – lies between the tendon and the calcaneus.

Q
A

There are four muscles in the deep compartment of the posterior leg

The popliteus is located behind the knee joint, forming the base of the popliteal fossa.

There is a bursa (sac-like structure containing a small amount of synovial fluid) that lies between the popliteal tendon and the posterior surface of the knee joint – it is called the popliteus bursa.

The flexor digitorum longus is a thin muscle and is located medially within the posterior leg.

The flexor hallucis longus muscle is located laterally within the posterior compartment (this is slightly counter-intuitive, as it is the opposite side to the great toe).

The tibialis posterior is the deepest out of the four muscles. It lies between the flexor digitorum longus and the flexor hallucis longus.

Q

-Tibia has a lateral condyle and medial condyle but does not have an epicondyle.

  • The medial and lateral epicondyles are found on the humerus, not the tibia.
  • The tibial tuberosity is a palpable prominence on the anterior face of the tibia. It receives insertions of the quadriceps and the patellar tendon
  • The soleal line is a short, oblique line on the posterior aspect of the tibia. It extends medially from the posterior shaft and serves as a landmark for the attachment of the soleus muscle

Q

Superior extensor retinaculum

Extensor Hallucis longus tendon

A

The superior extensor retinaculum is a single band of shiny fascia, just superior to the ankle joint.

Follow the tendon of this muscle to the big toe, or hallux. Extensor hallucis longus hides its muscle body between tibialis anterior and extensor digitorum longus. Gently separate these two muscles in lab to see it better.

Q

Anterior Compartment of leg

A

The muscles in the anterior compartment of the leg are a group of four muscles that act to dorsiflex and invert the foot.

These muscles are collectively innervated by the deep fibular nerve (L4-S1). The arterial supply is through the anterior tibial artery.

  • Tibialis Anterior
  • Extensor Digitorum Longus
  • Extensor Hallucis longus
  • Fibularis Tertius

The extensor hallucis longus is positioned deep to tibialis anterior and extensor digitorum longus. Its tendon emerges from between the two muscles to insert onto the big toe.

Tibialis anterior is the most medial muscle of the anterior compartment in the leg. Its insertion on the medial cuneiform and 1st metatarsal allow it to dorsiflex and invert the foot.

  • All of these arteries branch of the popliteal artery
  • The anterior tibial artery starts at the back of the leg and goes through the intrasseous space to get to the front of the leg. Here the anterior tibial artery supplies the anterior lower leg (only) and some parts of the knee.
  • Posterior tibial artery supplies the lateral part of the leg and the knee.
  • Fibular artery supplies the posterior and lateral parts of the leg.

Q

Iliopsoas

A
  • The iliopsoas is comprised of two separate muscles; the psoas major and iliacus.
  • These muscles arise in the pelvis and pass under the inguinal ligament into the anterior compartment of the thigh – where they form a common tendon.
  • Unlike many of the anterior thigh muscles, the iliopsoas does not perform extension of the leg at the knee joint.
  • Attachments: The psoas major originates from the lumbar vertebrae, and the iliacus originates from the iliac fossa of the pelvis. They insert together onto the lesser trochanter of the femur.
