Peroneal Tendon Syndromes Injuries to the peroneal tendons are common but not always clinically significant.They are misdiagnosed as a lateral ankle sprain most of the time, because isolated injury to the peroneal tendons is rare.Injury can occur in one or both peroneus longus and brevis tendons and is typically classified as acute or chronic.

Muscles in the Lateral Compartment of the Leg Muscles in the Lateral Compartment of the Leg. There are two muscles in the lateral compartment of the leg; the fibularis longus and brevis (also known as peroneal longus and brevis). The common function of the muscles is eversion – turning the sole of the foot outwards. They are both innervated by the superficial fibular nerve.

Calcaneus On the lateral side is commonly a tubercle called the calcaneal tubercle (or trochlear process). This is a raised projection located between the tendons of the peroneus longus and brevis. It separates the two oblique grooves of the lateral surface of the calcaneus (for the tendons of the peroneal muscles).

MRI Web Clinic â June 2014 The peroneus longus muscle originates from the lateral condyle of the tibia, proximal aspect of the fibula, and intermuscular septa and adjacent fascia and inserts at the plantar aspect of the medial cuneiform, proximal aspect of the first metatarsal, and occasionally at the base of the second metatarsal.steoarthritis commonly affects the sesamoid bones, especially the sesamoids of the first metatarsophalangeal (K) and first metacarpophalangeal joints. Radiographic findings include non-uniform joint space loss, osteophyte formation, bony eburnation, and flattening of a portion of the sesamoid 4,16.

Flexor Digitorum Longus Tendon It assists in plantar flexion of the foot, flexion of the four small toes, and inversion of the foot. The flexor digitorum longus tendon serves the flexor digitorum longus muscle, which extends from the back surface of the tibia to the foot.Its tendon passes along the plantar surface of the foot. There, it divides into four parts that attach to the terminal bones of the four small toes.he flexor digitorum longus tendon serves the flexor digitorum longus muscle, which extends from the back surface of the tibia to the foot.

Definition/Description Peroneal tendon subluxation is more commonly encountered in skiing, but also has been reported in other sports [1] [4]. The peroneus longus and brevis tendons sublux or dislocate from the lateral retromalleolar groove. This results from a tear or avulsion or significant laxity of the SPR [4].

Peroneal Tendon Injury There are two tendons, the peroneus brevis and peroneus longs. These tendons help to control the position of the foot during walking. They also responsible for the muscle contraction that moves the foot out to the side (eversion of the foot). Peroneal tendonitis is an irritation to the peroneal tendons.

Peroneus Longus Muscle Peroneus Longus Muscle. The peroneus longus muscle, whose name means “long muscle of the fibula” is a major muscle of the lower leg that plantar flexes and everts the foot at the ankle. Also known as the fibularis longus, it is the longest muscle that attaches to the fibula and is used specifically when balancing one’s weight on one foot.

The peroneal muscles of the lower leg Function. The fibularis longus and brevis muscles move both the upper and lower ankle joints. In the upper ankle joint they force a depression of the foot (plantar flexion) as their tendons run behind the flexion-extension axis.

- head. The extensor aponeurosis is identified and a longitudinal incision is made to visualize the extensor group. The extensor carpi radialis longus is then retracted back to visualize the brevis tendon. The pathologic tissue usually includes the origin of the extensor carpi radialis brevis and less frequently the anterior extensor aponeurosis or extensor longus. The pathologic tissue is then excised. Often osteotome decortication of the exposed lateral epicondyle is performed to

- The peroneus brevis tendon and peroneus longus tendon merge in a sheath behind the ankle. When the corresponding muscles are flexed, the tendons slide inside the sheath. Symptoms of injury to the peroneus brevis tendon include swelling as well as pain at the base of the little toe or in the outer ankle area.

Peroneus brevis Etymology[edit] The terms Peroneus (i.e., Longus and Brevis) and Peroneal (i.e., Artery, Retinaculum) are derived from the Greek word Perone (pronounced Pair-uh-knee) meaning pin of a brooch or a buckle. In medical terminology, both terms refer to being of or relating to the fibula or to the outer portion of the leg.

Peroneus Brevis The peroneal tendons are two strong tendons that connect the muscles on the outside of the leg to the bones in the foot. They run behind the bone in the ankle called the fibula. When they contract they move the foot down and out. They play an important role in stabilizing the foot on uneven surfaces.
