Spinal Flashcards
What curve and degree range are MIlwaukee braces generally indicated for
T curves btw 20-39*
Boston braces are as effective as milwaukee braces for scoliosis, but ALSO work on single and double curve patterns if the apex is at/below _____
T7
What has greater stability for primary Lumbar curves patterns of scoli compared to the milwaukee brace?
Low profile TLSO
Is the Boston or Milwaukee race more effective for Scheuermann’s Kyphosis
Milwaukee
What is the mechanism of injury for a C1/Jefferson Fracture?
Hyper extension force or axial load applied to the top of the head w/ fx to the atlas
Name the mechanism of injury for a C2 pedicles/Hangmans fracture
Hyperextension + distraction forces (like traumatic spondylolisthesis)
In a hangman’s fracture what part of the bone is actually fractured?
Pars interarticularis
A C2 Dens fracture occurs because of a combination of shear and compression loading (possibly resulting from a blow to the back of the head), but which type is unstable, and where is the odontoid fractured at?
Type 2 is unstable, fracture occurs at the base of the odontoid (halovest is indicated treatment)
For a C3-7 fracture with anterior compression from hyperextension what is the indicated treatment
Rigid collar
What two braces are total contact CTO with better intersegmental immobilization of the spine from the occiput to C7
Minerva & Miami JTO
Mechanism of injury for Dennis 1 classification fracture of the upper thoracic T1-8
Anterior compression –> Flexion & compression
A Dennis 2 classification for Upper thoracic T1-8 fractures can be treated with what?
Mild –> Jewitt
TLSO’s
What Dennis classification is also called a “Seatbelt fracture” and what area of the spine is generally effected?
Dennis 3 (Chance and slide --> flexion and distraction forces) Lower Thoracic T9-T12 impacted
How does a Dennis IV fracture dislocation occur?
Typically at upper lumbar L1-2
Translation, flexion, rotation, and sheer
NEEDS surgury
For a bilateral facet dislocation (which is caused by SEVERE flexion and rotation and the verterbra is displaced by more than half in the AP direction) What is the indicated treatment?
Surgery + Halo vest for 3 months
Mechanism of burst fx?
Axial compression + Sagittal flexion
A single level compression fracture can be treated with one of these two devices
Jewitt or CASH
What does CASH stand for
Crusiform Anterior Spinal Hyperextension
How many pads does a jewitt have on the anterior aspect?
What about the CASH
Jewitt–> 2 (one at the sternal notch is and the other around the pubic bone)
CASH –> 4 (Sternal notch, public bone, L and R side of body)
