The transverse metatarsal ligament is a narrow band which runs across and connects together the heads of all the metatarsal bones. It is blended anteriorly with the plantar (glenoid) ligaments of the metatarsophalangeal articulations.
The only movements permitted in the joints of the digits are flexion and extension; these movements are more extensive between the first and second phalanges than between the second and third. The flexor hallucis longus and flexor digitorum longus flex the interphalangeal joint of the big toe and lateral four toes, respectively. The tendons of ...
It is caused by compression of the tibial nerve underneath the flexor retinaculum of the foot. [1] People with tarsal tunnel syndrome have pain in the plantar aspect of the foot mostly at night. Weight bearing increases pain and weakness is found on intrinsic foot muscles with positive Tinel sign at the tunnel. There is no tenderness present on ...
These terms are used to resolve confusion, as technically extension of the joint is dorsiflexion, which could be considered counter-intuitive as the motion reduces the angle between the foot and the leg. [27] Dorsiflexion is where the toes are brought closer to the shin. This decreases the angle between the dorsum of the foot and the leg. [28]
The tendon of the extensor digitorum longus muscle extends the MTP joint by using the plantar fibro aponeurotic structure as a sling. The muscle becomes a deforming force if the MTP joint is held in an extended position over a long time, such as in a high-heeled footwear. The muscle extends at the IP joints when the MTP joint is flexed or in ...
Flexor: the toes curve down and inwards, and the foot inverts; this is the response seen in healthy adults. Indifferent: there is no response. This is called the neutral response, and has no clinical significance, as it does not rule out pathology. [5] Extensor: the hallux dorsiflexes, and the other toes fan out.
A patient recovering from surgery to treat foot drop, with limited plantar and dorsiflexion.. Foot drop is a gait abnormality in which the dropping of the forefoot happens out of weakness, irritation or damage to the deep fibular nerve (deep peroneal), including the sciatic nerve, or paralysis of the muscles in the anterior portion of the lower leg.
