Ankle Joint

 

in humans, the articulation of the bones of the shin with the foot. The tibia and fibula are part of the formation of the ankle joint; with their thickened ends (medial and lateral malleoli) embracing superiorly and laterally the ankle bone (talus) of the foot. The ankle joint is blockshaped, with one axis of rotation. It is surrounded by a capsule and is laterally attached by many tough ligaments. Its blood supply comes from the malleolar branches of the tibial and fibular arteries, which pass nearby. The ankle joint receives sensory innervation from the tibial nerve and the exterior branch of the deep peroneal nerve. Flection and extension of the foot occur at the ankle joint within a 90° radius, and they are usually combined with movements in the subtalus joint.

The ankle joint was dorsiflexed at 5[degrees]/s starting from 30[degrees] of plantar flexion, until the passive resistive torque corresponding to 20% of the pre-measured maximal voluntary plantar flexion torque was reached.
These muscles were selected due to their established role in regulating static and dynamic postural stability about the ankle joint. (3)
By comparing a variety of ankle rehabilitation robots, it was found that an optimal robotic design for comprehensive ankle rehabilitation should be characterized with appropriate workspace and actuation torque, aligned rotation center between the robot and the ankle joint, and adjustable robot posture.
However, in this osteosarcoma case report, it was not a total tibia replacement as no total ankle joint replacement was made, since part of the distal tibia was not removed.
Additionally, the large number of ligamentous structures and overall strength of the ligaments provide significant supplemental stability to the ankle joint articulation.
After the reduction of the dorsiflexion of the ankle joint, the flexion in the knee joints decreased, and the positive and the negative powers both decreased (Figures 9 and 11).
(10) In this case, ankle instability, major concern in these fractures should be the restoration of the stability of the ankle joint by repair of the ligamentous elements.
To evaluate the mechanical properties of the ankle joint, the ankle dorsiflexion angle and ankle joint passive torque were measured sequentially, and the muscle-tendon complex stiffness was calculated from these parameters.
Left ankle angle: the left ankle joint is the peak, the heel of the left foot and left knee joint respectively forms two lines with the left ankle joint;
These injuries are of utmost importance as the ankle transmits the whole body weight and the stability of ankle joint determines the locomotion.
To evaluate active and passive ankle joint position senses, 10[degrees] and 20[degrees] of ankle inversion and 15[degrees] and 30[degrees] of ankle plantarflexion were selected as the test angles.
