4 - Fracture Epidemiology and Imaging Fractures

Question 1

The most common sites in THO are:
a) ileum, femur, MCIII
b) ilium and tibia
c) MCIII, ilium and tibia

Answer 1

Mc3 (20%), ilium (16%) and tibia (14%).

Question 2

The most common sites in Standardbred horses are:
1) MCIII, P1 and P2
2) proximal sesamoid bones, P1 and MC/MT3 and pelvic
3) P1, P2, MC/MT3
4) P1, P3 and ilium

Answer 2

the most common fracture types in this population were those affecting the proximal sesamoid bones (0.32 per 100 horse months), followed by proximal phalangeal fractures (0.28 per 100 horse months) and both pelvic and Mc/Mt3 fractures

Question 3

What are the 2 main factores that are related to increased fracture risk?

Answer 3

longer interval since the last 60+-day period without a race and the distance exercised in the last month (suspensory apparatus failure) or two months (Mc3) were associated with an increased risk.

Question 4

Horses that canter for long distances increment the risk in wich type of fracture?

Answer 4

Pelvic or tibial stress fracture
