Long Bone Fractures: Cannon, Ulna, Femur, Tibia, Complications, ExFix, Stack Pinning, Mandibular Fractures Flashcards
These lectures were taught by Dr. Erika Little
T/F: The prognosis for complete displaced condylar fracture is good for returning to racing
False
T/F: Condylar fracture of the cannon bone is most commonly seen in racing thoroughbreds
True
T/F: Horses with incomplete non displaced condylar fracture have mild lameness
True
What is the optimal treatment for a simple transverse fracture of the cannon bone?
double plate fixation
What type of plate is shown here?
locking compression plate (LCP)
T/F: Locking compression plates (LCP) can be placed using standard screws or locking screws
True
T/F: Horses should be ambulatory and fully weight bearing immediately post-op after plating
True!
Where on the ulna do the triceps insert?
olecranon
apophysis in young patients
What are some differentials for this image?
- Humeral fracture
- Radial nerve paralysis
- Olecranon fracture
- Neuro dz (rare)
What is the treatment of choice for olecranon fracture repair?
ORIF
Open reduction, internal fixation
When repairing ulnar fractures in horses less than 1 year old, the distal screws should not engage the radius. Why not?
May lead to subluxation of the elbow
T/F: Prognosis for ulnar fractures is good with internal fixation
True
(67% - 87%)
What type of external coaptation is being used here?
Thomas-Schroeder Splint/Cast Combo
T/F: In farm animals, tibial fractures are commonly encountered in every age group and repair with external coaptation is frequently possible
True
What type of external fixator is being applied here?
Type 2
What type of external fixator is being used for this open fracture of the metacarpus?
Type 3
