Q

Where do grade IV - VI tibial plateau fractures occur?

A

Medial tibial plateau

17
Q

What is shown in this X-ray?

A

Tibial plateau fracture

18
Q

Why do lateral fractures require surgery less often than medial fractures?

A

There is a higher level of weight bearing on the medial aspect of the tibial plateau

19
Q

How can tibial plateau fractures be managed conservatively?

A

Above knee cast for 6-8 weeks

20
Q

What are some surgical options for tibial plateau fracture?

A
  • Open reduction Internal Fixation (ORIF - Plates and screws)
  • External fixator (Usually in comminuted)
  • Delayed total knee replacement
