- Anterior fibulocalcaneus muscles
The anterior fibulocalcaneus muscle is a rare accessory muscle of the ankle and an anatomical variant.
On this page:
Summary
- origin: the proximal third of the fibula, peroneus tertius muscle fascia, anterior crural intermuscular septum
- insertion: lateral calcaneus anterosuperior to the peroneal tubercle just below the Gissane angle
Gross anatomy
The anterior fibulocalcaneus muscle originates from the proximal fibula and the peroneus tertius muscle and travels parallel to the peroneus and extensor tendons anterior to the lateral malleolus to insert at the lateral calcaneus anterosuperior to the fibular trochlea (peroneal tubercle) 1-3.
History and etymology
The anterior fibulocalcaneus muscle was first described by the American anatomist H Wayne Lambert and Stavros Atsas in 2010 1.
Clinical importance
The anterior fibulocalcaneus muscle might be mistaken for pathology or the peroneus tertius muscle. It also serves as a potential harvest site for a tendon graft.
Related pathology
- anterior fibulocalcaneus muscle might be involved in anterolateral ankle impingement
