The ankle, the talocrural region [1] or the jumping bone (informal) is the area where the foot and the leg meet. [2] The ankle includes three joints: the ankle joint proper or talocrural joint, the subtalar joint, and the inferior tibiofibular joint. [3] [4] [5] The movements produced at this joint are dorsiflexion and plantarflexion of the ...
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] For example, when walking on the heels the ankle is described as being in dorsiflexion. [27] Similarly, dorsiflexion helps in assuming a deep squat position. [29]
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.
The normal biomechanics of the foot absorb and direct the occurring throughout the gait whereas the foot is flexible (pronation) and rigid (supination) during different phases of the gait cycle. As the foot is loaded, eversion of the subtalar joint, dorsiflexion of the ankle, and abduction of the forefoot occur.
It also functions to 'lock' the ankle, as in toe-kicking a ball, when held in an isometric contraction. [5] [better source needed] The movements of tibialis anterior are dorsiflexion and inversion of the ankle. However, actions of tibialis anterior are dependent on whether the foot is weight bearing or not (closed or open kinetic chain). When ...
Dorsiflexion of the foot: The muscles involved include those of the Anterior compartment of leg, specifically tibialis anterior muscle, extensor hallucis longus muscle, extensor digitorum longus muscle, and peroneus tertius. The range of motion for dorsiflexion indicated in the literature varies from 12.2 [8] to 18 [9] degrees. [10]
The ankle joint consists of the talus resting within the mortise created by the tibia and fibula as previously described. Since the talus is wider anteriorly (in the front) than posteriorly (at the back), as the front of the foot is raised (dorsiflexed) reducing the angle between the foot and lower leg to less than 90°, then the mortise is confronted with an increasingly wider talus.
An ankle fracture is a break of one or more of the bones that make up the ankle joint. [1] Symptoms may include pain, swelling, bruising , and an inability to walk on the injured leg. [ 1 ] Complications may include an associated high ankle sprain , compartment syndrome , stiffness, malunion , and post-traumatic arthritis .
