ABC ORTHOTICS WRITTEN PREP EXAM QUESTIONS WITH ACCURATE SOLUTIONS-
GRADED A+
The paraspinal bars of a TLSO: sagittal control should extend superiorly to the
spine of the scapula
The TLSO: Anterior control should be fitted with the patient in a
Supine position
What orthosis would be used to manage a patient with a T3 compression fracture?
TLSO: anterior control with cervical extension
In scoliosis management, lateral flexion radiographs are used to:
Determine if the curve is structural
The axial skeleton is attached to the appendicular skeleton at the:
Sternoclavicular and sacroiliac joints
The pad most commonly used in conjunction with a CTLSO is a:
Thoracic pad
,Abdominal muscles
Help increase intracavitary pressure Reduce loading on vertebral discs Decrease excessive
lordosis
A scoliosis patient is seen in clinic. Upon radiographic reading you note that the thoracic
curve apex is located at T6. Which orthosis is appropriate
Milwaukee CTLSO. The Milwaukee CTLSO system is utilized for scoliosis curves T7 and
higher. In some instances additions can be built into a boston brace system to simulate the
effectiveness of a Milwaukee system which can increase patient comfort and compliance
Posterior trim lines on an LSO extend from the sacrococcyxgeal joint to just inferior to
_____. Anterior trim lines extend from symphysis pubis to the
Inferior angle of the scapula, xiphoid process. LSO trim lines are chosen to span a distance
above and below the pathological area to maximize control and or guide motion "longer
lever arm = better control"
You are seeing a patient with a one year history of amyotrophic lateral sclerosis. She is
ambulating with bilateral canes, shows limited endurance and foot drop. Base on the
diagnosis what device would you recommend for trial
ALS is a progressive degenerative disease where due to the progressive nature you feel trial
of ankle foot orthosis would be appropriate due to her fatigue and foot drop. Amyotrophic
lateral sclerosis is a progressive motor neuron disease where the goal for mobility are to
maximize current function and provide access to devices that allow for independence
including orthosis.
,A patient is seen at the local hospital ortho/neuro floor. The patient presents with an
unstable odontoid fracture. Which orthosis would you recommend
HALO CTLSO is indicated for unstable C1 and C2 fractures. This orthosis spans a long
distance to maximize end point control
A patient is seen in clinic. The patient presents with DX: lower lumbar stenosis and a RX:
LSO align appropriately. Which option would you recommend
An LSO aligned in flexion will allow the spinal canal to relatively decrease occlusion and
whereby increase space for he spinal cord
When selecting anterior pin placement in a HALO CTLSO application, where is the proper
starting position
Lateral 1/3 of eyebrow, slightly superior to eyebrow. When choosing anterior pin placement
for a HALO this placement gives you a relatively safe starting position to avoid puncturing
sinuses, nervous system structures as well as to decrease superior migration of HALO ring.
When selecting posterior pin placement in a HALO CTLSO application, where is the proper
starting position
Slightly superior to ear, opposing the anterior pin directly, inferior to equator of the cranium.
By placing the posterior pins of a HALO, slightly superior to ear, opposing the anterior pin
directly, inferior to equator of the cranium you will optimize placement to avoid nervous
system structures as well as superior migration of the HALO
A patient you are working with has a medial nerve lesion, you would expect that they will
have loss of all functions except one of the following
, Flexor carpi ulnaris. Flexor carpi ulnaris in one of the few muscles that the median nerve
does not innervate on the anterior compartment of the forearm. In general the median
nerve serves the flexors of the forearm except for flexor carpi ulnaris which is innervated by
the ulnar nerve. Lesion to the median nerve can produce carpal tunnel syndrome, ape hand
deformity, denedictine deformity
Choose all answers that are clinical "visible by the eye" signs of scoliosis
Arm gap, shoulder asymmetry, pelvic obliquity, rib hump, and prominent scapula
True or false, when fabricating a williams flexion LSO for spondylolisthesis, the anterior
corset panel should be fabricated out of an inelastic material
False, When fabricating a williams flexion LSO for spondylolisthesis, the anterior corset
panel should be fabricated out of an elastic material so as not to limit sagittal plan flexion
In the hospital you see a 6 year old girl with spina bifida. You are consulted due to the
patient's club foot and 30 degree scoliotic thoracic curvature. Please circle on choice that
would be part of the normal treatment for a child with spina bifida
Prevent contractors due to neurogenic deformities, with hydrocephalus, decompress and
place shunt in place, prevent pressure sores and fit patient with a ankle foot orthosis and a
TLSO. Spina bifida is caused by incomplete closure of one or more neural arches that can
cause a wide range of impairments. Joint contractures and pressure ulcers are always a
risk for a patient with neurological deficits
Scoliosis is sometimes sub-divided into different types. What are signs of congenital
scoliosis
Wedge, bar, and hemi-vertebrae are common radiographic findings for congenital scoliosis
