Behind the lateral malleolus, a network of nerves and muscles around Origin insertion peroneal muscle ankle, fibularis longus attaches to the long tendon of muacle fibularis brevis in a common groove. The terms Origin insertion peroneal muscle i. The peroneus longus is provided by the superficial peroneal nerve. Views Read Edit View history. The lateral region of the cuboid is cut across by the muscle strap that extends up to the bone in a groove Orrigin into a canal by the long plantar ligament. Flexor Hallucis Oeroneal bends the big toe when you curl up your foot. The peroneus longus also everts the sole of the foot, and from the oblique direction of the tendon across the sole of the foot is an important agent in the maintenance of the transverse arch. The foot itself comprises 26 bones.
Being considered an exclusive human structure for a long time, fibularis tertius FT is believed to have a secondary function of foot dorsiflexion and eversion.
- It is the more superficial of the two lateral muscles of the lower leg.
- The Peroneus Longus is the longer, bigger, and much more superficial of both muscles of the lateral compartment.
- The ankle muscles move the foot and consist of the gastrocnemius, soleus, tibialis posterior, tibialis anterior, peroneus longus, peroneus brevis, flexor hallucis longus, flexor digitorum longus, extensor hallucis longus and extensor digitorum longus.
While the muscle group exists in many variations, it is normally composed of three muscles: peroneus longus , brevis and tertius. The peroneus muscles originates from lower two-third of the lateral surface of the shaft of the fibula and the anterior and posterior inter-muscular septa of the leg .
It inserts onto the metatarsals. The peroneus longus and brevis are much more similar to each other than they are to the peroneus tertius. The longus and brevis are both located in the lateral compartment of the leg , supplied by the fibular artery and innervated by the superficial fibular nerve , while the tertius is located in the anterior compartment , supplied by the anterior tibial artery and innervated by the deep fibular nerve.
Another difference between the longus, brevis and tertius is that while they all evert the foot ; the peroneus longus and brevis plantarflex the foot, while the peroneus tertius dorsiflexes it.
The peroneus muscles are highly variable and several variants have been noted as being occasionally present, such as peroneus digiti minimi and peroneus quartus.

Retrieved 4 August Afterward it enters downward and forwards above the peroneal trochlea of the calcaneus underneath the superior pulley of the inferior peroneal retinaculum. It inserts deep into the plantar aspect of base of the first metatarsal and medial cuneiform to the long plantar ligament. It crosses the lateral side of the cuboid , and then runs on the under surface of that bone in a groove which is converted into the peroneal canal by the long plantar ligament ; the tendon then crosses the sole of the foot obliquely, and is inserted into the lateral side of the base of the first metatarsal bone and the lateral side of the medial cuneiform. The peroneus longus also everts the sole of the foot, and from the oblique direction of the tendon across the sole of the foot is an important agent in the maintenance of the transverse arch.

Fibularis (Peroneus) Brevis Muscle - Attachments, Actions & Innervation
NCBI Bookshelf. Hajira Basit ; Benjamin J. Eovaldi ; Marco A. Authors Hajira Basit ; Benjamin J. Siccardi 1. The peroneus brevis muscle is the shorter of the two muscles that make up the lateral compartment of the leg with peroneus longus being the longer muscle. It receives innervation from the superficial peroneal nerve, and its arterial supply is by muscular branches of the peroneal artery. The origin of peroneus brevis is the lower two-thirds of the lateral fibula and inserts on the proximal fifth metatarsal.
The peroneus brevis muscle, also referred to as the fibularis brevis muscle, is located in the lateral compartment of the lower extremity below the knee, underneath the peroneus longus muscle. It is a small, relatively short muscle of the leg that originates from the lower two-thirds of the lateral surface of the fibula bone. Its muscle fibers traverse downwards and form into a tendon which runs just posterior to the lateral malleolus, crossing the ankle, and inserting on the styloid process of the proximal the fifth metatarsal bone.
The ankle joint is a relatively mobile joint that relies on its surrounding ligaments for stability. The structural ligaments of the ankle connect bones to bones and are deep to the muscles and tendons of the ankle and lower extremity. Muscles that cross the ankle joint have a mechanical action on the foot and ankle. The primary movements of the foot and ankle are plantar flexion, dorsiflexion, eversion, and inversion. The peroneal brevis muscle and tendon cross the ankle joint posterior to the fibula.
Foot eversion is tilting of the sole of the foot away from the midline, and foot inversion is the tilting of the sole towards the midline. Foot eversion requires a muscle to have an insertion on the lateral aspect of the foot, such as with peroneus brevis which inserts on the lateral foot at the proximal fifth metatarsal.
Plantar flexion describes the movement of the foot down towards the sole of the foot and dorsiflexion is the action of foot upward towards the shin. Plantar flexion requires the muscle to have an insertion relatively close to the ankle, such as with peroneus brevis which inserts on the proximal fifth metatarsal.
The ankle joint serves as the fulcrum for both eversion and plantar-flexion. Embryologic development of the limbs begins at the end of the fourth week of fetal development.
By the sixth week, the fetus develops hand plates and footplates. During limb development, the shape of the limb forms from mesenchymal cells, condensing and differentiating into chondrocytes which will ultimately differentiate into the bones and cartilage of the upper and lower extremity. Limb musculature is first seen around the seventh week. The mesenchyme migrates from the dorsolateral cells of somites out to the limb and differentiates into muscle cells.
The lower extremity muscles below the knee develop later than the proximal muscles of the lower extremity. The peroneal artery arises from the tibial-peroneal truck distal to the popliteal artery. The peroneal artery is also called the fibular artery. The peroneal artery is the blood supply to the lateral compartment of the leg.
Muscular branches of the peroneal artery supply the peroneus brevis muscle. Venous drainage is by superficial veins that drain into the small saphenous vein and by deep veins that drain into the posterior tibial vein.
The external iliac nodes then drain into lumbar aortic nodes. The peroneus brevis receives its innervation from the muscular branch of the superficial peroneal nerve L5-S2. The superficial peroneal nerve courses around the proximal fibula, where it is prone to injury.
Peroneus longus and peroneus brevis are the only two muscles of the lateral compartment of the leg. Peroneus brevis muscle lies underneath peroneus longus, is shorter, and has a thicker muscle belly than peroneus longus does. The tendon of peroneus brevis begins at roughly cm proximal to the tip of the lateral malleolus and then crosses the ankle where it makes an anterior turn at the distal fibula and inserts on the lateral aspect fifth metatarsal. The tendons of the peroneal brevis and peroneal longus muscles are contained together in a common synovial sheath.
At the calcaneus, the tendons of the peroneus brevis and peroneus longus are separated by the peroneal tubercle of the lateral aspect of the calcaneus. The peroneus brevis courses above the tubercle and the peroneal longus courses below the peroneal tubercle.
The superior and inferior peroneal retinacula function to prevent tendon subluxation as they secure the tendons of peroneal brevis and longus in place at the level of the ankle. The superior peroneal retinaculum covers the peroneal muscle tendons with attachments at the distal fibula and lateral calcaneus.
The inferior peroneal retinaculum covers the peroneal muscle tendons with insertions at the lateral calcaneus interior to the superior peroneal retinaculum.
The inferior peroneal retinaculum is contiguous with the inferior extensor retinaculum at the dorsum of the foot. Twenty percent of people have an accessory, peroneus quartus muscle, that passes through the superior peroneal retinaculum but not the inferior peroneal retinaculum and inserts on the lateral aspect of the calcaneus. For injuries to the peroneus brevis tendon conservative treatment is usually sufficient; however, in highly active individuals surgery to reattach or reconstruct the tendon may be required.
The peroneus brevis muscle is used in reconstructive and plastic surgery of the lower extremity most commonly in non-healing wounds related to diabetic lower extremity ulcers. The peroneus brevis muscle flap is used by plastic surgeons to reconstruct small defects in the lower third of the anterior leg.
The muscle along with the peroneal artery can be transposed to small distal wounds of the leg. Ankle and foot injuries are common in the occupational setting. Being aware of a few of the common pathologies associated with the peroneal brevis muscle and tendon is helpful in making a diagnosis in cases of ankle and foot injury. The most common injuries to the peroneal brevis muscle are to its tendon in the form of tendon sprain, dislocation, or splitting.
Supination-adduction SAD injuries to the ankle often involve damage to the lateral ligaments of the ankle, fracture of the distal fibula, and possibly an injury to the peroneal tendons and peroneal retinacula.
Occasionally, the base of the fifth metatarsal is also fractured in a lateral ankle sprain and the peroneal brevis tendon may pull on and detach the bone at the metaphyseal-diaphyseal junction, which is called a Jones fracture. Additionally, a strike to the lateral aspect of the foot can result in laceration of the peroneal brevis tendon.
There is a groove in the posterior aspect of the distal fibula is where the tendon of the peroneal brevis muscle sits with the tendon of peroneal longus behind it. The groove is variable depth and may be shallow, which is the reason that the peroneal tendons are the most commonly dislocated tendons in the ankle.
Another cause for tendon dislocation is the peroneus brevis tendon rubbing on fibula and causing an inflammatory periosteal reaction and bony proliferation which can cause chronic subluxation or displacement of the peroneal tendons. A longitudinal vertically oriented split of the peroneus tendon can also occur with subluxation. To access free multiple choice questions on this topic, click here.
