Schematic of Muscles of the lateral compartment of the lower leg1 1: Fibularis Longus 2: Fibularis Brevis Fibularis Longus Tendon and Insertion1

Muscle	Origin	Insertion	Innervation	Action
Fibularis longus	Proximal lateral surface of Fibula	Medial cuneiform Base of 1st MT	Superficial Fibular n. L5 - S1	TCJ: PF STJ: Eversion Arch: Transverse arch support

Origin

Proximal lateral surface of the fibiula¹

Insertion

Medial cuneiform¹
Base of 1st MT¹

Innervation

Superficial Fibular N. (L5, S1)¹

Action

TCJ: Plantarflexion¹
STJ: Eversion¹
Transverse arch: Support¹

Tendon

“The tendon of the fibularis (peroneus) longus runs superficially behind the lateral malleolus. Resisted pronation and plantar flexion of the foot make the tendon more prominent”²
