Description[edit | edit source]
The Peroneus Brevis (also known as Fibularis Brevis) is a short muscle that lies at the lateral part of the lower leg deep to the Peroneus Longus.[1] It is one of the three peroneus muscles (Pernoeus Longus, Peroneus Brevis and Peroneus Tertius).[2] The Peroneus Brevis along with the Peroneus Longus are commonly injured during a lateral ankle sprain and the tendon of the Peroneus Brevis muscle is the most commonly dislocated tendon.[1]
Origin[edit | edit source]
The Peroneus Brevis originates from the distal two-thirds of lateral fibula.[1] It's tendon passes downwards and loops posterior to the lateral malleolus.[2]
Insertion[edit | edit source]
The Peroneus Brevis inserts on the styloid process at the proximal end of the fifth metatarsal.[1][2]
Nerve[edit | edit source]
The Peroneus Brevis is innervated by the Superficial Peroneal nerve.[1]
Artery[edit | edit source]
The Peroneus Brevis receives its arterial supply from the muscular branches of the peroneal artery.[1]
Function[edit | edit source]
The Peroneus Brevis is responsible for 63% of the power needed to evert the foot as well as assists in plantar flexion along with the Peroneus Longus.[2][3] The peroneii muscle work together to provide dynamic lateral ankle stability during sudden ankle inversion stress.[3]
Clinical relevance[edit | edit source]
Avulsion fracture of the ankle
Assessment[edit | edit source]
Peroneus longus and brevis tests
Treatment[edit | edit source]
