Description
[edit | edit source]
The medial plantar nerve is the larger one of the two terminal branches of the tibial nerve, it covers most of the sole of the foot and supply multiple muscles which functioning on the toes.
Anatomy [1][edit | edit source]
General Course of Nerve:[edit | edit source]
It arises under the flexor retinaculum and runs forward deep to the abductor hallucis with the medial plantar artery on its medial side. It comes to lie in the interval between the abductor hallucis and the flexor digitorum brevis.
Branches:[edit | edit source]
Cutaneous branches: plantar digital nerves run to the sides of the medial three and the medial half of the fourth toe. The nerves extend onto the dorsumand supply the nail beds and the tips of the toes.
Muscular branches: it gives a branches to these four muscles, abductor hallucis, flexor digitorum brevis, the flexor hallucis brevis and the first lumbrical muscle.
Function[edit | edit source]
Innervates (sensory and motor):
[edit | edit source]
See the branches section above.
Movements produced: [edit | edit source]
Flexion of the big toe and abduction of toes.
Pathology/Injury[edit | edit source]
Physiotherapy Assessment[edit | edit source]
Observation:[edit | edit source]
Local observation for the sole of the foot is the first step of examination, notice any difference compaired with the unaffected side, injury or incision, bruises, lump and the skin color on the related area.
- As the atrophy muscle is a sign to indicate if there is an impairment of the nerve that innervates the affected muscle, it is difficult to be recognized with the small muscles.
Palpation:[edit | edit source]
You can assess the sensation of the areas supplied by the medial plantar nerve and palpate the related area to check any problems relating to the sensation (either hyper sensitivity or impaired sensation) and/or the tenderness degree.
Manual muscle test: [edit | edit source]
Examin the strength of the muscles that Innervated by the medial plantar nerve, by resisting the movement of the big toe flexion and toes abduction.
