P-3 Fracture
bar shoe, unless extensor process, then surgery
P-2 fracture
proximal interphalangeal joint arthrodesis
non-comminuted P-1 fracture
Lag screws
proximal sesamoids fracture
usually remove fragment. If mid-body use hemicerclage wire or screw compression
lateral condylar fracture
lag screws
medial condylar fractures
lag screws +/- plates, can get catastrophic fracture
dorsal cortical stress fractures of Mc-3
"saucer" fracture. Rest or osteostixis
dorsal splint bone fractures
associated with suspensory desmitis. Surgically excise
middle and proximal splint bone fractures
internal fixation if proximal. If mid-shaft can also do excision
carpal and tarsal slab fractures
screw fixation for carpal. Rest for tarsal
severely comminuted P-1 fracture
External fixation- customized or transfixation cast
traumatic disruption of suspensory apparatus
fetlock arthrodesis
diaphyseal MC-3 and MT-3 fractures
2 DCP plates (guarded for survival)
ulnar fractures
ONE DCP plate or pins and wires in small horses (tension band)
radius fractures
splint if non-displaced. 2 DCPs if surgery
humerus fracture
conservative treatment if minimally displaced, 2 DCPs if surgery or interockign nail, intramedullary stack pinning
scapular fractures
rest, excercise, lag screws
tibial fracture
2 DCPS
femoral fracture
2 DCPs, interlocking nail, intramedullary pinning

What is the surgery to correct upward fixation of the patella?
medial patellar ligament desmotomy. (don't usually do, usually strengthen quadriceps to fix)
What is curb?
long plantar ligament desmitis
How do you treat stringhalt?
lateral digital extensor tendon tenectomy to reduce proprioceptive stimulus
What couples the stifle and hock?
peronius tertius
What happens when the gastrocnemius tendon is cut?
caudal component of reciprocal apparatus is destroyed
