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 ...
The navicular bone in humans is located on the medial side of the foot, and articulates proximally with the talus, distally with the three cuneiform bones, and laterally with the cuboid. It is the last of the foot bones to start ossification and does not tend to do so until the end of the third year in girls and the beginning of the fourth year ...
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 ...
Anterior ligament of the lateral malleolus; Posterior ligament of the lateral malleolus; Interosseous membrane of leg; The inferior transverse ligament of the tibiofibular syndesmosis is included in older versions of Gray's Anatomy, but not in Terminologia Anatomica. [1] However, it still appears in some anatomy textbooks. [2]
Lateral to it is the intermediate cuneiform. It articulates with four bones: the navicular, second cuneiform, and first and second metatarsals. The tibialis anterior and fibularis longus muscle inserts at the medial cuneiform bone. [2] The intermediate cuneiform (second cuneiform or middle cuneiform) is shaped like a wedge, the thin end ...
Facing anteriorly, the head carries the articulate surface of the navicular bone, and the neck, the roughened area between the body and the head, has small vascular channels. [ 3 ] The body features several prominent articulate surfaces: On its superior side is the trochlea tali, which is semi-cylindrical, [ 6 ] and it is flanked by the ...
The antero-lateral border begins above in front of the head, runs vertically downward to a little below the middle of the bone, and then curving somewhat lateralward, bifurcates so as to embrace a triangular subcutaneous surface immediately above the lateral malleolus. This border gives attachment to an intermuscular septum, which separates the ...
The Malleolus (Latin: "small hammer") is the bony prominence on each side of the ankle. [12] These are known as the medial and 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.
