Abductor digiti minimi muscle of the foot
What is the Abductor digiti minimi muscle of the foot?
Abductor digiti minimi is a unipennate muscle found in the lateral aspect of the sole. As there are horizontal and vertical sets of foot muscles into four layers and three groups respectively, the complete address of this muscle is that it belongs to them;
The first layer of plantar foot muscles, along with the abductor hallucis and flexor digitorum brevis
Lateral plantar muscles, alongside the flexor digiti minimi, brevis, and opponens digiti minimi
Extending between the calcaneus and fifth digit, the role of abductor digiti minimi is to support the lateral longitudinal arch of the foot during walking and running by abducting the fifth toe.
Origin
Calcaneus and plantar aponeurosis.
Insertion
The lateral side of the fifth toe’s proximal phalanx base
Relations
This muscle is located just above the flexor digiti minimi brevis and deep within the lateral plantar fascia. The abductor digiti minimi muscle is the most lateral in the first layer and lies along the lateral border of the foot. The flexor digiti minimi brevis muscle and the lateral plantar artery and nerve are located medially to it.
Innervation
The lateral plantar nerve (S1, S3), a tibial nerve branch, innervates the abductor digiti minimi.
Blood supply
This muscle is supplied by the lateral plantar artery
Functions
This muscle is a much more powerful flexor of the fifth toe at its metatarsophalangeal joint, despite being referred to as the abductor.
Its role is similar to that of the abductor hallucis muscle from the opposite side of the foot; it keeps the concavity of the foot by keeping the lateral longitudinal arch during walking, running, and jumping.
Clinical relevance
In infrequent conditions, the muscle may be bifid. The further belly can be utilized as a flap in reconstructive medical procedures of the foot and might be remembered for Baxter’s neuropathy
Abductor digiti minimi muscle stretching
By flexing the little toe at the metatarsophalangeal joint, the intrinsic muscle of the foot known as the abductor digiti minimi pedis is stretched.
Abductor digiti minimi muscle strengthening
The abduction
Attempt to spread your toes outwards. The exercise is quite challenging, and the outer toes may not move at all. However, even if the toes do not move, the contraction of the muscles will continue. Ten times, three times a day, practice it.
FAQ
What causes abductor digiti minimi pain?
It is likely to feel an ache on the abductor digiti minimi, but irregular. Pain frequently arrives from walking on hard bottoms in hard shoes, particularly for fast walkers, or those with poor gait biomechanics. Ache over this site should always be ruled out against a fractured fifth metatarsal.
Can abductor digiti minimi be palpated?
This muscle activity makes a palpable muscle bulge, which might be visually observed, on the lateral foot along the fifth metatarsal. As the little toe abducts and then relaxes, the tendon connecting the fifth toe can be felt on the lateral side of the fifth metatarsophalangeal joint.
How do you stretch the abductor digiti minimi?
Put your toes on the bottom and curl them away from the sole. Turn the foot inward barely so your heel is facing outward. Attempt to push into the bottom with your foot for a greater stretch. Gradually, lower the right knee onto the bottom and maintain for approximately 30 seconds before releasing.
How do you treat abductor digiti minimi?
To self-release the Abductor Digiti Minimi, you will require a ball. Find the muscle. Standing on the ball while it is positioned over the trigger point and applying pressure with your leg’s weight while sitting or standing, depending on your preference, will help you release the muscle.
How do you relieve muscle pain in your foot?
A good soak
A warm Epsom salt foot bath can ease sore muscles and relieve swelling in your feet. To create an Epsom foot bath, the Farmers’ Almanac suggests adding one-half cup of Epsom salt to a container of warm water large adequately to submerge your feet. Soak your feet for approximately 20 minutes.
