Lateral retromalleolar region
Regio retromalleolaris lateralis
- Latin synonym: Regio retromalleolaris fibularis
Definition
The lateral retromalleolar region of ankle corresponds to the space situated behind the lateral malleolus of the fibula. It is located in the posterolateral part of the posterior ankle region.
The tendons of the peroneus longus and brevis traverse the lateral retromalleolar region of ankle to reach the sole of the foot. These muscles originate from the fibula in the lateral leg compartment. Upon passing behind the lateral malleolus of the fibula, the peroneus brevis attaches to the base of the 5th metatarsal bone, while the peroneus longus continues its course through the sole, reaching its medial border and contributing to the stability of the foot’s transverse arch.
