Nov 3, 2023 · Fibularis tertius is a muscle of the anterior calf whose function is to dorsiflex the foot. Learn everything about its anatomy and function at Kenhub!

Fibularis Tertius Syndrome is a condition characterized by catching, clicking, locking or popping of peroneus tertius tendon over ankle during walking. It is a rare condition of anterolateral ankle pain or rear foot pain.

In human anatomy, the fibularis tertius (also known as the peroneus tertius) is a muscle in the anterior compartment of the leg. It acts to tilt the sole of the foot away from the midline of the body and to pull the foot upward toward the body (dorsiflexion).

Jan 7, 2023 · The fibularis tertius is a muscle in the anterior compartment of the leg. It is an extension of the distal part of the extensor digitorum longus muscle and is not always present. Attachments: Originates with the extensor digitorum longus from the medial surface of the fibula.

Origin: Medial surface of fibula and adjacent interosseous membrane of leg. Insertion: Dorsal aspect of base and body of fifth metatarsal bone. Action: Dorsiflexes foot at ankle joint; assists in eversion of foot at subtalar and transverse tarsal joints. Innervation: Deep fibular nerve (L5-S1).

The Fibularis Tertius muscle, with its unique origin, insertion, muscle path, and function, plays a crucial role in the intricate system of muscles responsible for lower leg and foot movements. Its actions are essential for maintaining balance, stability, and efficient locomotion.

May 13, 2023 · The fibularis tertius muscle, also known as the peroneus tertius muscle, is a small muscle located in the lower leg. It is part of the lateral compartment of the leg and is one of the muscles that make up the group of muscles commonly known as the peroneal muscles.

Jan 2, 2023 · The peroneus tertius (fibularis tertius) is one of the muscles within the anterior compartment of the leg. Collectively, the muscles of the anterior compartment act to extend the toes, dorsiflex the ankle and invert the foot.

Apr 9, 2019 · The fibularis tertius muscle (FTM) is a rare anatomic variation. The prevalence of this exclusively human structure, which is found in the anterior compartment of the leg, is often underestimated, and it is believed that foot and ankle conditions are more difficult to manage in patients with an FTM.

Being considered an exclusive human structure for a long time, fibularis tertius (FT) is believed to have a secondary function of foot dorsiflexion and eversion. This study is an attempt to approach the issue from an anatomical perspective. A systematic literature search identified 35 studies (7601 legs) which met the inclusion criteria.
