Lower limb

Question 1

Between which 2 points does the short ligament of the femur run from and to, and what is its role

Answer 1

Runs from the head of the femur to the acetabulum, to help secure the femur

Question 2

What does a broken hip normally refer to?

Answer 2

When the neck of the femur is fractured. The neck is the weakest part of the femur and is often fractured

Question 3

Describe the femur between the shaft and neck

Answer 3

At the junction of the shaft and neck of the femur are the lateral greater trochanter and posteromedial lesser trochanter

Question 4

Describe the structure of the distal end of the femur

Answer 4

Distally, the femur broadens and ends in the lateral and medial condyles, which articulate with the tibia

Question 5

Where can you find the medial and lateral epicondyles?

Answer 5

The medial and lateral epicondyles flank the condyles superiorly

Question 6

What connects the tibia and fibula?

Answer 6

These 2 bones are connected by an interosseous membrane

Question 7

Describe the structure of the tibia at the proximal end

Answer 7

At the proximal end are the concave medial and lateral condyles. These are separated by the intercondylar eminence. Just inferior to the condyles is the tibial tuberosity, to which the patellar ligament attaches.

Question 8

Describe the structure of the tibia at the distal end

Answer 8

Distally, the tibia is flat where it articulates with the talus bone. Medial to the joint surface is the medial malleolus.

Question 9

What role does the fibula play in the knee and ankle joint

Answer 9

The fibula does not contribute to the knee joint and merely helps to stabilize the ankle joint

Question 10

Where is the distal and proximal end of the fibula?

Answer 10

Its proxiaml end is its head and the distal end is the lateral malleolus.
