flexor muscle of the big toe

Branch of the tibial nerve (roots S1 and S2).

Flexor hallucis longus muscle of the toe

The flexor hallucis longus (FHL) muscle is one of the three deep muscles of the hindfoot that attach to the plantar surface of the distal phalanx of the big toe. The other deep muscles are the flexor digitorum longus and the posterior tibialis; the posterior tibialis is the strongest of these deep muscles. All three muscles are innervated by the tibial nerve, which is one half of the sciatic nerve.

The long finger flexor muscle is located on the peroneal side of the tibia. It arises from the lower two-thirds of the posterior surface of the fibular shaft, except for 2.5 cm in the lowest part, from the inferior part of the interosseous membrane, from the intermuscular septum between it and the peroneal muscles laterally, and from the fascia surrounding the tibialis posterior covered, medial.

The fibers slope downward and backward, where they pass through the tarsal tunnel on the medial side of the foot and terminate in a tendon that runs almost the entire length of the hindfoot surface.

This tendon lies in a groove traversing the posterior surface of the inferior end of the tibia between the medial and lateral tuberosities of the posterior surface of the thigh and the inferior surface of the sustentaculum tali of the heel; in the sole of the foot it runs forward between the two heads of the flexor hallucis brevis and inserts at the base of the last phalanx of the thumb. The grooves in the talus and heel bone that house the tendon muscle are converted by the tendon fibers into separate canals lined with mucosa.

As the sole of the foot progresses, the tendon is higher and crosses from lateral to medial with the tendon of the long flexor finger, to which it is connected by a fibrous sheath.

variant

Typically, the gliding runs to the flexor of the fingers, and often an additional gliding runs from the flexors of the fingers to the flexors of the thumbs. The internal peroneocalcaneus rarely arises below or beyond the flexor of the great toe from the posterior aspect of the fibula, passes through the supporting posterior aspect of the flexor of the great toe, and enters the calcaneus.

function

Like the flexor digitorum longus and the posterior tibialis, the flexor longus of the big toe has the function of plantar flexion and rolling. However, it is unique in that it also performs the function of thumb flexion and assists in supination of the ankle.

Common injuries associated with the FHL tendon include tendonitis, tendinopathy, and muscle failure. Because the FHL muscle is small, injuries involving the muscle and its tendon are often overlooked. MRI can be used to assess the cause and condition of the FHL tendon. With this technique, cracks and bruises can be detected. Diagnosing an FHL injury can also be done using ultrasound, as it can show the muscle in motion and potential areas of stress. Behaviorally, an FHL injury can be evaluated by determining whether movement caused by the FHL muscle causes pain along the medial malleolus or under the big toe.

After passing through the tarsal tunnel, the tendon of the flexor longus muscle of the big toe should be bent around a bony landmark, the sustentaculum of the talus. Friction at this point can cause pain in the posteromedial aspect of the ankle. FHL tendonitis, commonly referred to as 'dancer's tendinitis', is common in ballerinas, gymnasts and runners. Inflammation and irritation at the waist is common due to excessive flexing of the fingers, which puts ten times your body weight on this small muscle and tendon.

Hallux saltans is a condition that results from overuse of the FHL muscle. When this happens, a knot forms along the FHL tendon, which can cause a flapping effect during contraction as the tendon pulls on surrounding tissue. If the tendon is left untreated and constantly irritated, it can constrict, making the big toe stiff and relatively immobile. This condition is called Hallux Rigidus.

Clinical Significance

The flexor longus tendon of the big toe creates the final pressure during the toe bearing phase of the gait cycle. At this point, the triceps tibialis is already maximally contracted, and the long flexor of the fingers completes its contraction. Thus thumb flexion is the last activity prior to lifting the foot off the ground prior to the limb transfer phase.

This muscle is involved in supporting the inner longitudinal arch of the foot.

Fractures of the talar support can cause the following, among others. Impingement of the long thumb flexor tendon or long finger flexor tendon, which may require reconstructive surgery. Postoperative care includes a tibial splint for 5-7 days, partial foot weight bearing (20 kg for 6-8 weeks in the patient's own shoes), and early exercise to improve ankle, subtalar, and transverse metatarsal mobility. The result is usually favorable, but better in isolated fractures. [3]

Treatment

A common foot strength exercise is done with a towel. Ask the patient to place the towel under the foot while sitting, and then ask them to grab the towel with the thumb of the foot and lift it off the floor.

This muscle can be strengthened by utilizing its role in maintaining balance. When performing balance exercises, using swinging boards makes the exercises more functional.

Further rehabilitation includes walking or running on a variety of surfaces, such as grass or sand, to further increase the functionality of the muscle.

The stretch can be done by straightening the thumb in the extended position with the foot in dorsiflexion. As with strengthening, a towel can be used when the patient is already ready to move. A towel can be wrapped around the toes and balls of the feet.

A swelling in the foot hurts

M. flexor hallucis brevis, the short flexor of the big toe, attaches to the medial sphenoid bone and the ligament. Between the toe flexors (dorsiflexors) and their plantar flexors (plantar flexors), among the flexors we find the long flexor of the common toe and the long flexor of the thumb F:

Removal of the staple line

followed by the long thumb flexor tendon, gymnasts and climbers. What these groups of people have in common is a considerable overload of the big toe flexor longus thumb (musculus flexor hallucis longus), a muscle of the rear group of the tibia. It occupies the most lateral position and inserts at the base of the distal phalanx. The long flexor muscle of the thumb, located deeper in the ankle, performs the flexion of the big toe in flexing the ankle with the help of the ankle flexors and anterior extensors (long toe flexor, long toe flexor, and posterior tibialis), and also performs the joint flexion movement of the tibia. – The flexor and extensor longus muscles of the big toe (hallux) mm. flexor and extensor hallucis longi;

Description

• Approach Insertion: on the lower two-thirds of the posterior surface of the fibula and the lower half of the adjacent intercondylar ridge.
• Course: Forms a downward and inward oblique muscle body that merges with a tendon, runs in the groove between the two tuberosities of the posterior surface of the calcaneus, and then in the calcaneal groove before merging with the plantar surface. It runs through the flexor tendon of the long toe to the big toe. Its fibers are divided into two at the large tendon, which comes out of the middle third of the foot. As a result, he can only contract to a limited extent, but withstands deflection very well. Your tendon, as a rule, is deprived of fleshy fibers two toes above the tibia, descends vertically and slides behind this joint, guided by the intertibial groove of the tibia and talus. Arriving at the bottom, it abruptly changes direction and thus leaves the hindfoot joint. It pulls forward, inward, and downward, where it passes under the sustentaculum of the talus (where it crosses the long flexor of the fingers, with which it usually joins the ankle). Like other posterior and deep tendons, it has a sheath and its own synovial sheath.
• end point End Point: It ends at the base of the plantar surface of the thumb distal phalanx.

The big toe flexor is innervated by the tibial nerve, an internal branch of the sciatic nerve.

vascular supply

It is supplied with blood by the posterior tibial and peroneal lateral arteries.

Anatomically, the long thumb flexor is the flexor of the two thumb joints. It is therefore the flexor of the distal phalanx at the proximal and the flexor of the proximal at the first metatarsal; however, it is also the extensor of the foot (plantar flexor) and is involved in adduction and supination of the foot. It is the abductor of the foot.

However, these activities are secondary, because during walking in the foot and toe phase, the big toe is immobile in relation to the ground. This muscle then works concentrically: it counteracts the pull exerted on it by the extension of the foot towards the ankle. This muscle is very strong and works eccentrically: its fibers are divided into two on the broad tendon. Therefore, it can only contract to a limited extent, but is very resistant to dissipation. Several effects are achieved with minimal expenditure of energy:

1. He straightens the foot by pulling up the sustentaculum of the talus and pushing the head of the M1 back.
2. He tightens the bicep clamp by pulling it over the base of the fibula. This causes the ankle to flex as the body moves forward (the calcaneus shaft is wider at the front than at the back). So, the long flexor of the big toe is one of the most important components of ankle stability because it tightly compresses the body of the talus between the two ankles.
