Bones, compartments and anterior leg Flashcards
What are the tibia and fibula held together by?
By sheet of fibrous material called the Interosseous membrane.
This provides additional stability to the skeletal bones
How are the tibia and fibula joined?
At the proximal and distal aspects
The superior or proximal tibio-fibular joint is a plane type of synovial joint
The inferior or distal tibio- fibular joint is a type of fibrous joint
1- Green= Lateral compartment
2- Blue= ANterior compartment
3- Yellow and red= Posterior compartment
What is the anterior bony prominence you can feel about 3 to 4 cm below the knee joint?
Tibial tuberosity
Straighten your leg – which tendon attaches onto the superior aspect of this?
Patellar tendon
What bone makes up the medial malleolus?
Tibia
What bone makes up the lateral malleolus?
Fibula
What is dorsiflexion?
movement of the ankle upwards
What is plantar flexion?
the movement of the ankle downwards
What is eversion?
movement of the ankle outwards
What is inversion?
movement of the ankle Inwards
1. Tibialis anterior
2. Extensor digitorum longus
3. Extensor hallicus longus
4. Fibularis Tertius – this is a small muscle found at the distal aspect of the leg
What are the muscles of the anterior compartment mainly involved in?
Mainly dorsiflexion and inversion of the ankle joint and extend of the toes.
The neurovascular structures of the leg are continuations with what?
Structures in the thigh as they continue distal through the popliteal fossa
