Tibia Flashcards
What is the common bony landmark on anterior surface of tibia?
Tibial tuberosity
What structure is between lateral and medial condyles of tibia?
Intercondylar eminence
Intercondylar eminence provides the attachment of?
1.menisci
•anterior horn of lateral & medial menisci
•posterior horn of lateral & medial menisci
2.cruciate ligaments
Anterior Cruciate ligament (ACL)
Posterior Cruciate ligament (PCL)
The 2nd strongest bone in our body?
Tibia
Tibia is also called?
Shin bone
Joints related to tibia?
- Tibiofemoral
- Proximal Tibiofibular
- Distal Tibiofibular
- Talocrural (ankle joint)
Tibial tuberosity provides the attachement sote for which muscle?
Quadriceps muscle
Via patellar tendon
How many borders and surfaces of shaft of tibia?
3 borders
3 surfaces
Name the border of tibia?
Anterior border
Medial border
Lateral (Interosseous) border
Name the surfaces of tibia?
1.Medial surface (flat -shin)
2. Lateral surface (slightly concave)
3. Posterior surface
What is the most important feature of posterior surface?
A ridge called soleal line (for origin of soleus muscle)
A nutrient artery proximal to soleal line
The part of tibia that forms inner portion of ankle?
Medial malleolus
Most common fracture of tibia is where and why?
At the junction between upper 2/3 and lower 1/3
Because of poor blood supply
Tibial tuberosity receives the attachment of which ligament?
Ligamentum patallae
Which is the weight-bearing bone of the leg?
Tibia
The shin of tibia is formed by which border?
Anterior
The tibial condyles form a flat surface known as_____? And what does this structure articulate with?
Tibial plateu
It articulate with femoral condyles to form key articulation of knee joint
The intercondylar tubercles of the tibia articulate with _______ of femur?
Intercondylar fossa
Fractures of proximal tibia are known as?
Tibial plateau fractures
(At tibial condyles)
What does tibial plateau result from?
Direct injury to knee joint on lateral side
What happens in Fractures of the distal end of tibia?
Asscociated with ankle joint
Medial malleolus can be fractured
Caused by ankle being twisted inwards (over-inversion)
The tallus of foot is forced against medial malleolus
What is interosseous tibia infusion or interosseous access?
It is form of vascular access in emergency situations
This procedure is used for infusion of blood and fluids directly into bone marrow.
When it is impossible to find intravenous line.
What are the 2 main sites in tibia suitable for intraosseous access?
Anteromedial surface
2.5 cm below tibial tuberosity
Proximal to medial malleolus
