Fractures Flashcards
region I
hoof –> dist MC III/MTIII
region II
dist MC III/MTIII –> Dist radius/hock
region III
Dist radius/hock –> elbow/ stifle
region IV
elbow/ stifle –> Distal scapula/prox to stifle
kimzey splint
suspensory apparatus
monkey splint
phalanges and MC III
fracture in region 1
have to stabilise the phalanges
o Little polster, but even surface (about 1 cm cotton wool)
o Dorsal aspect in one line – elevate the heels - the cast must evolve the hole cannon bone- must be able to flex the leg
o Elastic or “Gaze” bandage strongly pulled
o Fieberglas-cast
name of splint for suspensory apparatus
kimzey splint
splint for pahalnges and McIII
monkey
good orthopaedic painkiller
firocoxib
transport of horses with fracture
FL - head facing backward
HL - head facing travel direction
fracture classification is based on
relationship with environment
displacement
fracture pattern
etiology
fractures based on environment
open or closed
fractures based on displacement
un placed or displaced (translation, angulation or shortening)
fracture based on fracture pattern
simple
compound
green stick
transverse
oblique
spiral
comminuted
impacted
depressed avulsion
- Simple
– little or no bone displacement
- Compund –
fracture ruptures the skin and bone protrudes
- Green stick
– occurs mostly in foals whose bones have not calcified or hardened
- Transverse
– crack perpendicular to long axis of the bone – displacement may occur
- Oblique
– diagonal crack across the long axis of the bone
- Spiral
– diagonal crack involving a “twisting” of the bone about the longitudinal axis
- Comminuted
– “crushing” fracture – more common in adults
- Impacted
Avulsion
– fragment of bone is pulled away by tendon
- Depressed
– broken bone is driven up into the other
