Distal. The medial malleolus is a bony projection continuing inferiorly on the medial aspect of the tibia. It articulates with the tarsal bones to form part of the ankle joint. On the posterior surface of the tibia, there is a groove through which the tendon of tibialis posterior passes.
What is the distal part of the tibia?
The distal tibia bears medial and posterior prominences known as the medial malleolus and posterior tibial process, respectively. The medial malleolus is longer than the lateral tibial surface and articulates with the medial surface of the talus to form the medial gutter of the ankle joint.
What causes tibia bone pain?
Shin pain may be caused by inflammation or damage to your muscles and bones including:
- Anterior compartment syndrome of the lower leg
- Bone fracture
- Shin splints
- Stress fracture of the tibia (shin bone)
- Tendonitis (inflammation of one or more leg muscle tendons)
What is proximal tibia?
The proximal tibia is the upper portion of the bone where it widens to help form the knee joint. In addition to the broken bone, soft tissues (skin, muscle, nerves, blood vessels, and ligaments) may be injured at the time of the fracture. Both the broken bone and any soft-tissue injuries must be treated together.

- Function. All long bones are limb bones that assist with weight-bearing and movement. ...
- Associated Conditions. There are many conditions that can affect the tibia. ...
- Rehabilitation. ...
What is distal to the tibia?
The distal, lateral tibia contains a notch for the fibula, also known as the incisura fibularis, and is surrounded by strong ligaments that make up the ankle syndesmosis, which will be discussed later. The distal aspect of the fibula projects past the tibial plafond and is referred to as the lateral malleolus.
Is tibia distal to fibula?
The distal ends of the fibula and tibia that overlap the talus are known as the malleoli (“little hammers”). The lateral malleolus is the distal end of the fibula, whereas the medial and posterior malleoli are part of the tibia.
What is proximal to the tibia?
The proximal tibia is the upper portion of the bone where it widens to help form the knee joint. In addition to the broken bone, soft tissues (skin, muscle, nerves, blood vessels, and ligaments) may be injured at the time of the fracture. Both the broken bone and any soft-tissue injuries must be treated together.
Which bone is distal to the femur and proximal to the tibia?
The tibia is located in the lower leg medial to the fibula, distal to the femur and proximal to the talus of the foot.
What is distal and proximal to the tibia?
Proximally, the tibia articulates with the femur to form the tibial-femoral joint of the knee. Distally, the tibia articulates with the talus to form the talocrural joint of the ankle.
Is the talus distal to the tibia?
Body. The body of the talus is cuboidal in shape and articulates with the distal end of the tibia.
What is inferior to tibia?
At the inferior end of the tibia, the interosseous border is replaced with the fibular notch in which the distal end of the fibula fits.
What is the proximal distal?
In medicine, it refers to parts of the body further away from the center. For example, the hand is distal to the shoulder. The thumb is distal to the wrist. Distal is the opposite of proximal. Distal refers to distance, while proximal indicates proximity.
What is proximal to the fibula?
Like other long bones, the fibula has a proximal end (with a head and neck), a shaft, and a distal end. The fibula and tibia run parallel to each other in the leg and are similar in length but the fibula is much thinner than the tibia. This is indicative of the weight-bearing contributions of each bone.
What are the distal bones?
The distal bones (lateral to medial) are the trapezium (“table”), trapezoid (“resembles a table”), capitate (“head-shaped”), and hamate (“hooked bone”) bones. The hamate bone is characterized by a prominent bony extension on its anterior side called the hook of the hamate bone.
What is distal to the femur?
The distal femur is where the bone flares out like an upside-down funnel. The distal femur is the area of the leg just above the knee joint. Distal femur fractures most often occur either in older people whose bones are weak, or in younger people who have high energy injuries, such as from a car crash.
What bone is distal to the femur?
tibiaThe lower (distal) end of your femur forms the top of your knee joint. It meets your tibia (shin) and patella (kneecap).
What is distal to the fibula?
The distal end of the fibula forms the lateral malleolus which articulates with the lateral talus, creating part of the lateral ankle. The posterior and lateral tibia form the posterior and medial malleolus, respectively.
Is tibia anterior to fibula?
tibiae /ˈtɪbii/ or tibias), also known as the shinbone or shankbone, is the larger, stronger, and anterior (frontal) of the two bones in the leg below the knee in vertebrates (the other being the fibula, behind and to the outside of the tibia); it connects the knee with the ankle.
Where is tibia in relation to fibula?
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.
Is tibia medial or lateral to fibula?
The tibia (shin bone) is a long bone of the leg, found medial to the fibula. It is also the weight bearing bone of the leg, which is why it is the second largest bone in the body after the femur. Fun fact here is that 'tibia' is the Latin word for tubular musical instruments like the flute.
Where is the medial border of the tibia?
The medial border is most prominent on the medial aspect of the middle third of the of tibia. Tibia is only one of the many bones making up the human body.
What is the superior surface of the condyles?
The superior surfaces of the condyles are flattened and together they form the superior articular surface called the tibial plateau. Here, the tibial condyles articulate with the femoral condyles within the knee joint. The articular surfaces are separated by two small prominences, the medial and lateral intercondylar tubercles. These tubercles form the intercondylar eminence, which is bordered by the anterior and posterior intercondylar areas.
What is the anterior intercondylar area?
The anterior intercondylar area features attachment sites for many structures. Anterior to posterior they are: the anterior horn of the medial meniscus, the anterior cruciate ligament, and the anterior horn of the lateral meniscus. The posterior intercondylar area also has facets for structures to attach.
What is the tibia in 2021?
Last reviewed: June 17, 2021. Reading time: 13 minutes. The tibia (shin bone) is a long bone of the leg, found medial to the fibula. It is also the the weight bearing bone of the leg, which is why it is the second largest bone in the body after the femur.
Which joint is the medial meniscus sandwiched between?
The medial meniscus is sandwiched between the tibia and femur in this joint with attachments to all margins except for the lateral margin.
Where is the interosseous border?
The interosseous border begins inferior to the tubercle of the iliotibial tract and descends down the lateral surface of the tibia. This border connects to the interosseous border of the fibula by the interosseous membrane.
Which part of the tibia is the site of muscle attachment?
Proximal part. The proximal end of the tibia features several important landmarks which function as sites of muscle attachment and articular surfaces: two tibial condyles (medial and lateral) separated by intercondylar areas (anterior and posterior).
What condyles articulate with the femoral condyles to form the knee joint?
The tibial condyles articulate with the femoral condyles to form the knee joint. caption] Shaft. The shaft of the tibia is prism-shaped, with three borders and three surfaces; anterior, posterior and lateral. For brevity, only the anatomically and clinically important borders/surfaces are mentioned here.
What is the interosseous border?
Lateral border – also known as the interosseous border. It gives attachment to the interosseous membrane that binds the tibia and the fibula together.
What is the medial malleolus?
The medial malleolus is a bony projection continuing inferiorly on the medial aspect of the tibia. It articulates with the tarsal bones to form part of the ankle joint. On the posterior surface of the tibia, there is a groove through which the tendon of tibialis posterior passes.
What is the fibula notch?
Laterally is the fibular notch, where the fibula is bound to the tibia – forming the distal tibiofibular joint.
What causes a fracture in the medial malleolus?
At the ankle, the medial malleolus can be fractured. This is caused by the ankle being twisted inwards ( over-inversion ) – the talus of the foot is forced against the medial malleolus, causing a spiral fracture. This rarely happens in isolation and typically the lateral malleolus is also fractured; potentially producing an unstable fracture that requires operative management.
Where is the intercondylar eminence located?
Located between the condyles is a region called the intercondylar eminence – this projects upwards on either side as the medial and lateral intercondylar tubercles. This area is the main site of attachment for the ligaments and the menisci of the knee joint. The intercondylar tubercles of the tibia articulate with the intercondylar fossa of the femur.
Which structure articulates with the femoral condyles to form a flat surface?
The proximal tibia is widened by the medial and lateral condyles, which aid in weight-bearing. The condyles form a flat surface, known as the tibial plateau. This structure articulates with the femoral condyles to form the key articulation of the knee joint.
What is the Tibia
Tibia is one of the two long leg bones of the lower leg. It is a weight-bearing bone, and also known as the shinbone or shankbone.
Where is the Tibia Located
As mentioned, the tibia is located in the lower leg, extending from the knee to the ankle. More precisely, it is situated on the distal side of the femur and the proximal side of the talus of the foot. The tibia is also located medially to the other bone of the lower leg, called the fibula.
Anatomy – Parts of the Tibia
It is a long bone with two ends, proximal and distal, and an intervening shaft. The part lying on the side of the knee is known as the proximal tibia, whereas the part lying on the side of the foot is known as the distal tibia.
Muscles Attached
Tibia has many muscles attached to it. Some originate from the bone, whereas some get inserted into it.
What is the classification of a fractured tibia?
Doctors often classify tibia fractures into the following categories: The broken ends of the tibia line up correctly and stay in place during the healing process. The fracture is horizontal, and the bone can become unstable if the fibula is also broken. The tibia is moved out of place when it breaks.
How long does it take for a fractured tibia to heal?
Some shaft fractures of the tibia take as little as four months to heal, with more extreme cases taking a minimum of six months to heal. Your overall health and the extent of your fracture will influence your recovery time.
