1
Trochanteric extension
Usually unilateral
Acts as an extended lever arm to address decompensation in conjunction with the lumbar pad to address a lumbar curve
2
Lumbar pad
Anteriorly directed force from the posterior aspect of the orthosis
Derotates the spine by applying force to the transverse process
3
A lumbar pad will be utilized in which type/s of curves?
Lumbar
Thoracolumbar
T10, 11 thoracic curves
4
Thoracic Pad
Medially directed force from the lateral aspect of the orthosis
Influences the vertebra by the articulation with the ribs
5
What type/types of curves will require the addition of a thoracic pad?
Thoracic curves with apices at T8-T11
6
Thoracic window
Placed contralateral in relation to the thoracic pad
Will always be larger than the thoracic pad to allow for rib excursion
7
Thoracic extension
Constraining force for thoracolumbar curves
Terminates at the superior endpoint on the side opposite of the apex of the curve
8
Axillary extension
Used on the side of decompensation in conjunction with the trochanteric extension
Medially directed force
9
Gusset
Elastic material that is plastic welded to the module
Provides structural integrity and assists in the "righting reflex"
10
The superior anterior trimline is placed:
At the level of the xiphoid process
11
The inferior anterior trimline should be placed:
to allow 1cm clearance at the anterior thigh with the hips flexed at 90 degrees
12
The inferior anterior trimline should _____ the symphysis pubis.
cover
13
The superior posterior trimline should terminate ______ inferior to the ________.
2cm; inferior angle of the scapula
14
The inferior posterior trimline should allow ______ clearance from the chair when sitting with the hips ________.
2cm; flexed at 90 degrees
15
The superior and inferor lateral trimlines are:
dictated by the blueprint design
16
The lateral trimlines should follow the _______ slope of the ribs
downward
17
The side opposite the trochanteric extension should allow ______ above the trochanter
2 cm
