Osteology of the distal femur, patella, tibia and fibula Flashcards

1
Q

What are the proximal (medial and lateral) and distal (medial and lateral) borders of the linea aspera?

A

Proximal medial = Pectineal line
Proximal lateral = Gluteal tuberosity
Distal medial = Medial supracondylar line
Distal lateral = Lateral supracondylar line

Q

What prevents the patella from displacing laterally in the trochlear groove?

A
  • More prominent lateral femoral condyle (than medial) = deeper trochlear groove
  • Vastus medialis obliquus (VMO)

Q

What are the main functions of the patella?

A
  • Acts as a fulcrum (enables quadriceps to directly cross anterior aspect of the knee)
  • Protection
  • Reduce frictional forces (between quadriceps and femoral condyles)

Q

What is the tibial plateau?

A

Flat surface on proximal tibia formed by the medial and lateral condyles
-this articulates with the femoral condyles

A

Main site of attachment for ACL and menisci of knee located at the centre of the intercondylar area (between the medial and lateral intercondylar tubercles)

Q

Describe the route of the common peroneal/fibular nerve down the leg and what is its clinical importance?

A

Winds around the posterior and lateral surface of the neck of fibula
-Vulnerable to damage in proximal fibular fracture

17
Q

What is the lateral melleolus?

A

Bony projection in the distal lateral aspect of the fibula
