What is the anatomical definition of the leg?

The leg is the portion of the lower limb located between the knee and ankle joints. It is often studied together with the dorsum of the foot for a comprehensive understanding of anterior lower limb anatomy.

What are the key bony landmarks on the front of the leg?

Key bony landmarks include the tibial tuberosity (below the knee), the anterior border of the tibia (the shin), and the head of the fibula (posterolateral to the tibial tuberosity). These structures are important for palpation and clinical assessments.

Where can I feel the dorsalis pedis artery pulse?

The dorsalis pedis artery pulse is typically felt about 5 cm distal to the malleoli, lateral to the tendon of the extensor hallucis longus muscle when the foot is dorsiflexed.

What is the significance of the head of the fibula?

The head of the fibula is a critical landmark because the common peroneal nerve winds around the neck of the fibula here, making it susceptible to injury in this area.

How can I identify the tendon of tibialis anterior?

The tendon of tibialis anterior becomes prominent on the anterior ankle, especially when the foot is inverted. It crosses medially and is a key structure for movement and palpation.

What are the main soft tissue landmarks on the dorsum of the foot?

Main soft tissue landmarks include the extensor digitorum brevis muscle, visible as a soft elevation on the lateral dorsum during toe extension, and the first metatarso-phalangeal joint, located just in front of the ball of the big toe.

Where is the tuberosity of the fifth metatarsal located?

The tuberosity of the base of the fifth metatarsal is the most prominent lateral bony landmark of the foot, found midway between the heel and the base of the little toe.
