What does the medial malleolus articulate with?

talus
The medial malleolus, a bony projection of the distal end of the tibia, articulates with the medial surface of the talus. The lateral malleolus, an enlargement of the distal end of the fibula, articulates with the lateral aspect of the talus.

How much weight does the tibia support?

The tibia is a weight-bearing bone capable of withstanding forces at least five times body weight. Its sturdy nature can be enhanced with progressive weight-bearing exercise or reduced with sedentary habits.

What does the medial malleolus do?

The medial malleolus is the bony bump on the inner side of the ankle. This is the end of the shin bone (tibia) and forms the support for the inner side of the ankle joint. The medial malleolus is also the attachment of the major ligament on the inner side of the ankle, called the deltoid ligament.

What does it mean when your talus hurts?

Because the talus is important for ankle movement, a fracture often results in substantial loss of motion and function. A talus fracture that does not heal properly can lead to complications, including a limp, arthritis, and chronic pain. For this reason, most talus fractures require surgery.

Do any muscles attach to the talus?

The talus (plural: tali 4), also known as the astragalus 4, is a tarsal bone in the hindfoot that articulates with the tibia, fibula, calcaneus, and navicular bones. It has no muscular attachments and around 60% of its surface is covered by articular cartilage.

What causes pain in the medial malleolus?

Tibialis posterior tendinosis, which is degeneration of the tibialis posterior tendon, and tibialis posterior tenosynovitis are the most common causes of pain behind the medial malleolus.

What percent of body weight does the fibula support?

Fibula bone plays a minor role in bearing the weight of the body as we walk. The tibia bears approximately 80% of the body weight. The fibula bone bears only 15 to 20% of the body weight.

Which bone is the major load bearing bone of the lower leg?

Tibia and fibula are the two long bones located in the lower leg. The tibia is a larger bone on the inside, and the fibula is a smaller bone on the outside. The tibia is much thicker than the fibula. It is the main weight-bearing bone of the two.

How long does medial malleolus take to heal?

You have sustained a fracture to your medial malleolus (bone on the inside of ankle). Please see the picture below to understand where this injury is. This normally takes approximately 6 weeks to unite (heal) although pain and swelling can be ongoing for 3 to 6 months.

How do you treat medial malleolus pain?

Avoiding the activities that produce the pain or stress the bursa of the medial malleolus is the first line of treatment. Avoiding activities that produce pain or stress of the bursa of the medial malleolus and associated tendons (jumping, running, etc.) The use of ice to reduce inflammation and pain.

Which is larger the tibia or the medial malleolus?

The medial malleolus is an anatomical region of the tibia bone, which is the larger of the two lower leg bones. You can feel this area as the bump on the inner side of your ankle joint. It bears 90 percent of the weight bearing load, so this is a common fracture.

Where are the malleoli located in the ankle?

The malleoli are specific parts of the tibia and fibula that form the ankle. These consist of the lateral malleolus, which is at the end of the fibula, the medial malleolus, which is on the inside of the tibia (shinbone), and the posterior malleolus, which is at the back of the tibia.

Who is the orthopedic surgeon for the lateral malleolus?

Jonathan Cluett, MD, is a board-certified orthopedic surgeon with subspecialty training in sports medicine and arthroscopic surgery. The lateral malleolus is the name given to the bone on the outside of the ankle joint. This bone is part of the fibula, one of two bones of the leg; the other leg bone is called the tibia (shin bone).

Do you need a plate for a medial malleolus fracture?

The lateral malleolus is treated with a plate and screws as usual. However, the medial malleolus is typically treated with screws alone. On rare occasions some medial malleolar fractures still require a plate. This decision is usually made at the time of surgery.
