The lateral malleolus is found at the foot end of the fibula, of a pyramidal form, and somewhat flattened from side to side; it descends to a lower level than the medial malleolus. The medial surface presents in front a smooth triangular surface, convex from above downward, which articulates with a corresponding surface on the lateral side of ...
Between the muscle's attachments to the head and body of the fibula, there is a gap through which the common fibular nerve passes to the front of the leg. [2] The muscle ends in a long tendon, which runs behind the lateral malleolus of the ankle in a groove that it shares with the tendon of the fibularis brevis; the groove is converted into a ...
The leg muscles acting on the foot are called the extrinsic foot muscles whilst the foot muscles located in the foot are called intrinsic. [28] Dorsiflexion (extension) and plantar flexion occur around the transverse axis running through the ankle joint from the tip of the medial malleolus to the tip of the lateral malleolus.
Each leg is supported by two bones, the tibia on the inner side (medial) of the leg and the fibula on the outer side (lateral) of the leg. The medial malleolus is the prominence on the inner side of the ankle, formed by the lower end of the tibia. The lateral malleolus is the prominence on the outer side of the ankle, formed by the lower end of ...
The postero-lateral border is prominent; it begins above at the apex, and ends below in the posterior border of the lateral malleolus. It is directed lateralward above, backward in the middle of its course, backward, and a little medialward below, and gives attachment to an aponeurosis which separates the peronaei on the lateral surface from ...
The muscle group is normally composed of three muscles: fibularis longus, fibularis brevis, and fibularis tertius. [1]The fibularis longus and fibularis brevis are located in the lateral compartment of the leg and are supplied by the fibular artery and the superficial fibular nerve.
Fracture of both sides of the ankle with dislocation as seen on anteroposterior X-ray. (1) fibula, (2) tibia, (arrow) medial malleolus, (arrowhead) lateral malleolus. An ankle fracture is a break of one or more of the bones that make up the ankle joint. [20] Symptoms may include pain, swelling, bruising, and an inability to walk on the injured ...
The fibular retinacula (also known as peroneal retinacula) are fibrous retaining bands that bind down the tendons of the fibularis longus and fibularis brevis muscles as they run across the side of the ankle. (Retinaculum is Latin for "retainer.") These bands consist of the superior fibular retinaculum and the inferior fibular retinaculum.
