- Weak plantar flexion
For example it points the foot down and out
Origin: 1. Tibia – Lateral condyle
- Fibula – A. Head B. Proximal two thirds C. Deep fascia
Insertion: First metatarsal – Base (lateral side) – Medial cuneiform
Common distortions caused by tightness is over-pronation
FIBuLARIS (PERONEuS) BREVIS
Joint Action performed by the Foot
- Eversion
- Pronation
Joint Action performed by the Ankle
- Weak plantar flexion
Origin: Fibula – distal two thirds Intermuscular septum
Insertion: Fifth metatarsal – Base (lateral aspect)
Common distortions caused by tightness is over-pronation
FIBuLARIS (PERONEuS) TERTIuS
Joint Action performed by the Ankle and Foot
- Dorsiflexion
- Eversion – respectively
For example it points the foot up and out
Origin: Fibula – Distal one third *Intermuscual septum, Interosseous membrane
Insertion: Fifth metatarsal – Base (dorsal aspect)
