Question 3
What would be the treatment for this type of fracture?
Answer:
Type III and IV hip fractures are considered unstable and with high risk of femoral head avascular necrosis, hence are treated with arthoplasty (either hemi- or total hip replacement). Type I and II hip fractures are considered stable and can be treated with internal fixation, preserving the head.

What is the difference between a hemi- and a total hip arthroplasty?
Answer:
A total hip arthroplasty consists of replacing both the acetabulum and the femoral head, while hemi-arthroplasty generally only replaces the femoral head.
Question 5

Answer:
Infection, haematoma, non-union or malunion, implant failure, periprosthetic fracture, loosening or dislocation
