Medial and lateral malleoli

The articular facet of the lateral malleolus (bony prominence on the lower fibula) forms the lateral border of the ankle joint while the articular facet of the medial malleolus (bony prominence on the lower tibia) forms the medial border of the joint. The lower extremity of the fibula is the lateral malleolus and lower end of the tibia is the medial malleolus.

The medial malleolus is the largest of the three bone segments that form your ankle.

Medial and lateral malleoli. The medial malleolus is a part of the tibia’s base. Malleolus, little hammer] the protuberance on both sides of the ankle joint; Posterior, lateral multifragmentary, and medial fractures.

Posterior, lateral simple, and medial fractures. The lateral malleolus is a bony prominence on the fibula, one of the long bones that makes up the lower leg. A similar protrusion on the outer side, called the lateral.

(malleoli is plural for malleolus.) in most cases of bimalleolar fracture, the lateral malleolus and the medial malleolus are broken and the ankle is not stable. Bony bump on the inside of your ankle. Bimalleolar ankle fracture is a fracture that occurs in both the lateral and medial malleoli at the distal end of the tibia and fibula bones that articulate with talus bone to form the ankle joint or tibiotalar joint.

Avulsion of lateral surface of calcaneus beneath lateral malleolus This allows the articular surfaces to glide upon each other and assures the cartilage surfaces to move freely. On the ap and oblique views look for.

The medial malleolus is the largest of the three bone segments that form your ankle. Any fracture involving the most distal portions of the fibula or tibia, commonly known as the lateral and medial malleoli, respectively synonyms: The lower extremity of the fibula is the lateral malleolus and lower end of the tibia is the medial malleolus.

The examiner stabilizes the patient’s heel by holding the calcaneus with one hand and palpates the distal edges of the medial malleolus for tenderness or swelling with the other hand. The lateral malleolus is the lower end of the fibula, the medial malleolus is the lower end of the tibia, and the medial malleolar sulcus is the posterior rim of the distal part of the tibia. Look closely at the medial, lateral, and posterior malleoli for evidence of fracture.

The lateral malleolus is the low end of the fibula. Twisting force on the ankle that leads to supination or pronation of the midfoot relative to the ankle and internal or external rotation of the talus within the joint. Osteochondral fracture at the medial and lateral corners dome of the talus.

This joint is in the mortise and tenon joint classification. Open subtypes (3) posterior, lateral simple fractures, and deltoid rupture. The medial aspect of the lateral malleolus articulates with the lateral surface of the talus, while the lateral aspect of the medial.

If the lateral injury involves an avulsion fracture of the tip of the lateral malleolus, with a medial malleolar fracture (oblique or vertical), this is classified as an ao/ota 44a2.2 fracture. Small bony flakes are present at the tips of both the medial and lateral malleoli. Both malleoli serve as the proximal attachments for the collateral ligaments of the ankle.

The articular facet of the lateral malleolus (bony prominence on the lower fibula) forms the lateral border of the ankle joint while the articular facet of the medial malleolus (bony prominence on the lower tibia) forms the medial border of the joint. A bimalleolar equivalent fracture means that in addition to one of the malleoli being fractured, the ligaments on the inside (medial) side of the ankle are injured. Bony protrusion felt on the outside of the ankle.

The medial malleolus is the medial projection of bone from the distal tibia. The medial malleolus is the spherical bony protrusion on the inner side of the leg, just above the ankle joint. The medial malleolus is formed by the lower part of your tibia and makes up the inner side of the ankle.

It is frequently involved in ankle fractures. The lateral malleolus is formed by the lower section of the fibula and makes up the outer side of the ankle. Medial malleolus, medial tarsal bones, and posterior tibial artery.

When a medial malleolus fracture occurs by itself. Check the width of syndesmosis and medial clear space of the ankle mortise. The fibula is the narrowest of the long bones, situated on the outside of the leg, with this prominence creating the distinctive bump on the outside of the ankle.

Moving from the distal extent of the medial malleolus along a line joining the navicular tubercle, the examiner moves along the. These regions are commonly referred to as the medial, lateral or posterior malleoli. The lateral malleolus projects laterally from the distal fibula (fig.

In the distal end of the ankle mortise sits the trochlea tali, the upper surface of the talus. Orthopaedists classify the lesions according to which bone is involved. The other two are the lateral and the posterior malleolus.

While both the medial and lateral malleolus are two separate structures, many people simply use the term malleolus to identify the. Felt on the back of your ankle and is also a part of the base of the tibia. Complete radiological evaluation (ap, lateral and ap with internal rotation) is crucial for correct classification and decision making.

Fracture of the distal tibia and/or fibula. On the lateral side there is a flexible support by the fibula,.
