Tibial Fractures in LAs

Question 1

signalment for tibia fractures in LAs

Answer 1

rare overall -foals: proximal physeal fractures (usually salter harris type 2); often open on medial aspect -bovine: usually diaphyseal

Question 2

salter harris type 2 fracture of proximal tibial physis in foals usually leads to _______

Answer 2

lateral metaphyseal fragment

Question 3

cause of salter harris type 2 fracture of proximal tibial physis in foals

Answer 3

usually kicked

Question 4

treatment for salter harris type 2 fracture of proximal tibial physis in foals

Answer 4

double tension band: stabilize fracture with T plate on MEDIAL side; then place two lag screws + wire in figure 8 tension band fashion ***remove implants at 8 weeks so doesn’t disrupt growth

Question 5

what to remember when repairing salter harris type 2 fracture of proximal tibial physis in foals

Answer 5

Question 6

Answer 6

double plate (craniolateral and craniomedial) + plate luting (EXCEPT if using LCP plate)

Question 7

plate luting

Answer 7

place cement/OMMA impregnated with antimicrobials to increase contact and stability of plates used with diaphyseal tibial repair in horses CANNOT use with LCP plate

Question 8

what plate can you NOT do plate luting with?

Answer 8

LCP

Question 9

treatment of tibial fractures in cattle

Answer 9

• if valuable: double plate (craniomedial and craniolateral)
• intramedullary interlocking nail
• circular external fixation
• external coaptation: full limb cast with Thomas schroeder splint or walker splint)
• combination of implants + external coaptation: align fragments with screws and wires, then use thomas schroeder splint

Answer 10

true
