Salter-Harris Fractures involvement
all types involve the physis (epiphyseal plate)
for one and 5, only the physis is injured
2-4 - metaphysis and/or epiphysis is fractured
- M, E, ME: 2: Metaphysis, 3:Epiphysis, 4: M & E
Salter-Harris Fractures type I
physis is widened, distorted, or displaced by traction or shear force
Salter-Harris Fractures type V
physis is crushed or compressed by axial copression
Salter-Harris Fractures type II
Metaphysis fractured
Salter-Harris Fractures type III
epiphysis fractured
Salter-Harris Fractures type IV
Metaphysis and Epiphysis fractured
what is the Salter-Harris system used for?
classify fractures in CHILDREN ONLY
What is a Jefferson’s fracture?
cervical spine;
caused by heavy object falling directly on the head or hitting head while diving.
at least two fractures of c1
What is a Hangman’s fracture?
cervical spine;
occurs often in MVA or hangings
B/L pedicle fracture with anterior displacement of C2
What is a Clay shoveler’s fracture?
cervical spine;
result of flexion injury in the lower cervical spine in which the spinous process is broken or fractured
What is a Chance fracture?
Thoracolumbar spine;
horizontal fracture of a vertebra, usually result of a MVA where the seat belt immobilizes pelvis but upper body is thrust forward
What is a burst/compression fracture?
thoracolumbar spine;
collapse or compression of vertebral body, usually caused by fall from a height
What is spondylolysis?
defect in pars interarticularis, appears as a collar on the “Scottie dog”
best seen in oblique view
What is spondylolisthesis?
bilateral pars interarticularis defect causing misaligned vertebrae causing forward slip, usually L5-S1
What is a bucket handle fracture?
pelvis;
fracture through ischiopubic rami on one side and fracture of SI joint on other side
What is a malgaine fracture?
pelvis;
fracture through ischiopubic rami and SI joint on same side
What is an avulsion fracture?
pelvis;
a small piece of bone is separated from the origin or insertion site of a tendon
how is imaging usually done if there is a suspected AC joint separation?
shoulder XR taken with pt holding weights; 3 grades
clavicular fracture most frequently occurs ____ (proximal, distal, middle)
middle third of the bone
What should you look for on imaging for a radial head fracture?
difficult to see; look for ant and post fat pad signs
What is a Monteggia fracture-dislocation (night stick)?
caused by receiving a blow when protecting oneself; dislocation of radial head and fracture of ulna
What is a Galaezzi fracture-dislocation?
caused by falling on outstretched hand and dislocating the distal radio-ulnar joint and fracturing the distal radius
Mnemnonic for elbow fractures
policeman Radii Galeazzi tried to hit thief Ulna Monteggia for stealing his bike. Ulna Monteggia blocked the blow to his forearm and tripped policeman Radii Galeazzi who fell on his outstretched hand
What is a Colles’ fracture?
