How many metatarsals are in each foot? How are they numbered?
There are five number from the big toe to the pinky toe.
One metatarsal has a prominent tuberosity; which one is it and why does it matter?
It's the fifth and it's because it is a common site of fractures.
What is the name of the fracture of the second metacarpal?
I don't know. We're studying feet not hands.
The medial aspect of the ________ has a shelf-like over hang that is called the what?
The subtentaculum tali.
Name the tarsal bones.
The cunieforms lie between two bones. What is the medial bone and what is the lateral bone?
The navicular is medial and the cuboid is lateral.
Which cueiform is the largest? The smallest?
The Medial is the largest.
The intermediate is the smallest.
The leg consists of two bones. Which one is medial and which one is lateral?
The tibia is medial while the fibula is lateral.
What are the lateral and medial condyles of the tibia? What is their function?
Smooth facets on the superior surface or the tibia.
Their purpose is to form smooth articulation between the femur.
What are the "peaks' created by the plateaus on the tibia known as?
Medial and lateral intercodylar tubercules.
What is the name of the sharp ridge that runs on the anterior surface of the tibia?
The anterior crest.
True or False?
The anterior tubercle of the tibia does not overlay the fibula in on the anteriolateral surface?
The anterior tubercle does indeed overlay the fibula on the anteriolateral surface.
The lateral surface of the tibia is flattened and contains a triangular notch for what?
Articulation with the fibula.
What is unique about the condyles of the femur?
There is a 5-7 cephallic degree needed to open the joint space on radiographs. This is due to the medial condyle being lower that the lateral condyle when the femur is vertical.
What portion of the femur articulates with the acetabulum of the hip?
The superior portion. It forms a ball and socket joint.
What are the large eminences located at the distal end of the femur?
The larger medial condyle and the smaller lateral condyle.
The medial condyle contains something very important what is it?
The aductor tubercle, the raised bony area that receives the adductor muscle.
What is so important about the aductor tubercle radiographically?
It is what we look at for rotation in a lateral projection.
Where is the apex of the patella located? What about the base?
The apex is the point on the inferior aspect of the patella.
The base is the superior aspect.
What are the main ligaments of the knee?
Posterior cruciate ligament
Anterior cruciate ligament
In regards to the knee why are the tibial plateaus important?
The tibial plateaus are where the medial and lateral meniscus sit.
The meniscus are _______ on the ________ side and _________ on the _________ side.
How many bones does the calcaneous articulate with and what are they?
The cuboid anteriorly
The talus superiorly
How may articulations are there at the subtalar joint? What is the signifigance?
3. They help to keep the body's weight evenly distributed.
This is an opening found in the middle of the subtalar joint which allows ligaments to pass through.
What is the calcaneous' contribution to the sinus tarsi?
The calcaneal sulci help make up the sinus tarsi.
How many bones does the talus articulate with? What are they?
The tibia and fibula superiorly
the calcaneous inferiorly
The navicular anteriorly
How many bones does the navicular articulate with and what are they?
Posteriorly with the talus.
Anteriorly with the three cuneiforms.
Do the cuneiforms articulate with any bones?
Yes. They articulate with four bones.
The calcaneous proximally
The lateral cuniforme medially and the 4th and 5th metatarsals distally.
How is the mortise joint formed?
It is formed by the lateral mallelous and the medial mallelous. They form a type of socket structure that articulates with the superior portion of the talus.
True or False
The calcaneous fits into the mortise.
The talus is the superior most portion of the foot and it is what fits in the mortise.
