  1. Lateral plantar nerve - Wikipedia

    The lateral plantar nerve ( external plantar nerve) is a branch of the tibial nerve, in turn a branch of the sciatic nerve and supplies the skin of the fifth toe and lateral half of the fourth, as well as most of the deep muscles, its distribution being similar to that of the ulnar nerve in the hand . It passes obliquely forward with the lateral plantar artery to the lateral side of the foot, lying between the flexor digitorum brevis and quadratus plantae and, in the interval between the ...

  2. Plantar nerve - Wikipedia

    Lateral plantar nerve. The lateral plantar nerve supplies quadratus plantae, flexor digiti minimi brevis, adductor hallucis, the dorsal and plantar interossei, three lateral lumbricals and abductor digiti minimi. Cutaneous innervation is to the lateral sole and lateral one and one half toes (like the ulnar nerve ).

    the lateral proper plantar digital nerve supplies the lateral side of the 5th digit and a branch for innervation of the Flexor digiti quinti brevis; the 4th common plantar digital nerve communicates with the third common plantar digital branch of the medial plantar nerve and divides into two proper digital nerves, which supply the adjoining sides of the fourth and fifth toes.

    From Wikipedia, the free encyclopedia The proper plantar digital nerves of lateral plantar nerve are nerves of the foot that arise from the superficial branch of the lateral plantar nerve. The superficial branch splits into a proper digital nerve and a common digital nerve: the proper digital nerve supplies the lateral side of the little toe,

    Damage to the deep fibular nerve can result in foot drop. The plantar digital nerves from the medial plantar nerve provide sensory innervation to the skin of the plantar aspect of the toes, except the medial part of the big toe and the lateral part of the little toe and the motor innervation of the first lumbrical.

  9. What Is the Lateral Plantar Nerve? (with pictures)

    Oct 14, 2020 · The lateral plantar nerve is a nerve of the sole of the foot. Originating from the sciatic nerve, which runs down the back of the leg, and below from the tibial nerve, which splits off from the sciatic, the lateral plantar serves the skin and muscles of the outer foot. This nerve gives sensation to the pinky toe and the outside of the fourth toe.

    Heel pain is a common presenting complaint to the foot and ankle specialist, with a wide differential diagnosis including plantar fasciitis, fat pad atrophy, calcaneal stress fracture or apophysitis, inflammatory arthropathy, neoplasia, and infection1. One of the more elusive diagnostic considerations in heel pain is entrapment of first branch of the lateral plantar nerve (Baxter’s nerve impingement)2,3. Baxter’s nerve is a mixed sensory and motor nerve, providing motor innervation to the abductor digiti minimi (ADM) muscle2,4,5. Baxter’s nerve impingement can produce symptoms indistinguishable from plantar fasciitis6,7,8,9. While this diagnosis has been said to account for up to 20% of heel pain, it is often overlooked relative to other causes of heel pain8,10,11. Weakness of the ADM may be present but is difficult to detect clinically9. Electrodiagnostic studies are invasive and the results in heel pain can be inconclusive9,13,14. MR can be used to detect denervation-related muscl...

    Within the ankle tarsal tunnel, the posterior tibial nerve (PTN) bifurcates into medial (MPN) and lateral (LPN) plantar nerves. These nerves exit the tarsal tunnel and continue along the plantar aspect of the foot. The MPN travels anterior to the LPN, carrying sensory information from the medial two thirds of the plantar foot, and motor innervation to the flexor digitorum brevis, abductor hallucis, flexor hallucis brevis, and first lumbrical9. The LPN carries sensory information from the lateral plantar aspect of the foot, 5th toe, and lateral half of the 4th toe. Motor innervation involves all the remaining foot muscles, not innervated by the MPN9. The first branch of the LPN, Baxter’s nerve (also known as the inferior calcaneal nerve), originates from the LPN at various levels beneath the deep fascia of the abductor hallucis muscle. The nerve courses vertically between the abductor hallucis and quadratus plantae muscles, then makes a sharp 90 degree horizontal turn, coursing later...

    MRI has been shown to be extremely valuable in demonstrating muscular changes associated with denervation. MRI is more sensitive to tissue changes within muscle compared to ultrasound or computed tomography and has advantages compared to electrodiagnostic studies due to its non-invasive nature, superior anatomic detail, ability to demonstrate pathology in muscles with dual innervation18, and ability to exclude alternative diagnoses (fracture, neoplasia, fasciitis). Normal muscle demonstrates intermediate signal on T1 and fluid sensitive sequences. Acute and subacutely muscle denervation is best evaluated with fluid sensitive sequences, such as T2-weighted imaging with fat suppression (T2FS) or short tau inversion recovery (STIR) images, exhibiting increased signal within the muscle belly compared to normal muscle, related to neurogenic muscular edema18,19. Gadolinium enhancement within muscle will also occur in the acute to subacute phases of denervation18. In the setting of Baxter’...

    Initial treatment strategy of Baxter’s nerve entrapment is conservative, typically involving a combination of rest, non-steroidal anti-inflammatory medicines, corticosteroid injections, and orthotics1,21,22. If recalcitrant pain exists despite conservative treatment, operative intervention has proven successful1,21,23,24. Neurolysis of Baxter’s nerve is performed with deep fascia release of the abductor hallucis muscle. An impinging heel spur or tight plantar fascia is also partially removed or released, if it is associated with the entrapment2. Endoscopic approaches to the surgery11 and radiofrequency ablation techniques22have also been described. The first patient above (Figures 1a,1b), underwent decompression of the tarsal tunnel in conjunction with Baxter’s nerve release, completely resolving her lateral foot pain.

    Baxter’s nerve impingement is a difficult clinical diagnosis and often overlooked in the presentation of heel pain. MRI can be used to evaluate for denervation effects of Baxter’s nerve impingement by identifying abnormalities of the ADM muscle belly. In addition, potential causes of impingement (e.g. calcaneal spur, soft tissue mass, enlarged vessels) and associated pathology (e.g. plantar fasciitis, tendon pathology) may be seen, and alternative differential diagnoses (e.g. stress fracture) can be excluded.
