The lateral malleolus is the prominence on the outer side of the ankle, formed by the lower end of the fibula. The word malleolus ( / m ə ˈ l iː ə l ə s , m æ -/ [ 1 ] [ 2 ] ), plural malleoli ( / m ə ˈ l iː ə ˌ l aɪ , m æ -/ ), comes from Latin and means "small hammer ".
Ankle X-ray is only required if: There is any pain in the malleolar zone; and, Any one of the following: Bone tenderness along the distal 6 cm of the posterior edge of the tibia or tip of the medial malleolus, OR; Bone tenderness along the distal 6 cm of the posterior edge of the fibula or tip of the lateral malleolus, OR
In the human body, the tarsus (pl.: tarsi) is a cluster of seven articulating bones in each foot situated between the lower end of the tibia and the fibula of the lower leg and the metatarsus. It is made up of the midfoot (cuboid, medial, intermediate, and lateral cuneiform, and navicular) and hindfoot (talus and calcaneus).
The talus (/ ˈ t eɪ l ə s /; Latin for ankle [1] or ankle bone; [2] pl.: tali), talus bone, astragalus (/ ə ˈ s t r æ ɡ ə l ə s /), or ankle bone is one of the group of foot bones known as the tarsus. The tarsus forms the lower part of the ankle joint. It transmits the entire weight of the body from the lower legs to the foot. [3]
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 ...
The mortise view is an AP x-ray taken with the ankle internally rotated 15-20 degrees since the foot is naturally externally rotated relative to the ankle. [9] In addition to these views, a full-length view of the tibia and fibula may be necessary to evaluate for injuries to the proximal fibula associated with Maisonneuve fractures .
Fibular hemimelia or longitudinal fibular deficiency is "the congenital absence of the fibula and it is the most common congenital absence of long bone of the extremities." [1] [2] It is the shortening of the fibula at birth, or the complete lack thereof. Fibular hemimelia often causes severe knee instability due to deficiencies of the ligaments.
This damages the ligaments on the inside of the ankle and fractures the fibula at the point of contact (usually just above the tibiofibular syndesmosis). A better way to visualize this is the two hands of a clock, with one hand facing 12 and the other facing 6. The vertical line they form represents the fibula of the person's right leg.
