ORTHOTICS WRITTEN EXAM 2024 ACTUAL EXAM WITH 200
COMPLETE EXAM QUESTIONS AND DETAILED VERIFIED
ANSWERS (100% CORRECT ANSWERS)
It is early in the recovery phase of a patient with a L3
complete spinal cord injury. The expect outcome would
most likely be? - CORRECT ANSWER >>>>Some recovery of
function since damage is to the peripheral nerve roots.
Spinal cord ends at L1 at the conus medularis; a spastic
bladder is expected with an upper motor neuron injury
With regard to spondylolithesis, what are the radiographic
signs that contraindicate orthotic intervention and indicate
a surgical candidate? - CORRECT ANSWER >>>>Superior
vertebrae angulation of 50 degrees relative to inferior
vertebrae
Anterior translation of the superior vertebrae over the
inferior vertebrae
Patient presents with an L1 burst fracture from a
snowmobiling accident; which orthosis is most appropriate?
- CORRECT ANSWER >>>>Custom polymer TLSO - to have

coverage spaning several levels above and below the
pathological site. Burst fractures are most unstable in the
transverse plane. Custom TLSO is most efective at rotational
control and has proper coverage
With a traction injury to the anterior division of the brachial
plexus you would expect: weakness of the elbow flexors,
wrist flexors, and forearm pronators. What other muscle
weakness would you expect? - CORRECT ANSWER
>>>>Thumb abductors - Anterior nerve root gives rise to C6
nerve root, median nerve, which abducts the thumb
Patient presents with a T11 anterior compression fracture.
Patient is neurologically intact and the fracture is stable.
Which orthoses would be appropriate? - CORRECT ANSWER
>>>>CASH TLSO and Jewett TLSO - both effective for
anterior compression FX near the thoracolumbar junction.
By placing the thoracic spine in extension, pressure is
removed from anterior portion of the vertebral body
allowing natural bone remodeling to occur
When taking an impression for a patient with a L5/S1
spondylolihesis, how would you position the patient if they
were allowed to stand for the procedure? - CORRECT
ANSWER >>>>Ask the patient to flex their hips and knees
slightly to reduce lumbar lordosis for optimal alignment for
spondylolisthesis

You have a patient for an evaluation post stroke. You notice
a forward flexed posture. What positive muscle length test
do you expect with this? - CORRECT ANSWER >>>>Thomas
test - test for iliopsoas (hip flexion) tightness
What are some of the biomechanical principles behind a
LSO corset? - CORRECT ANSWER >>>>Kinesthetic reminder -
to use proper posture and to discourage certain motions
Increase intradominal pressure - solidifies soft tissie
hydrostatically whereby providing support to the lumbar
spine
Multiple three-point pressure systems - work to hold proper
alignment and resist/stop certain motions
You are working with a physical therapist for gait training
with a patient wh has complete L1 spinal cord injury along
with a patient with L4 spinal cord injury. What orthosising
do you expect and with what ambulation tolerance
respectively? - CORRECT ANSWER >>>>L1: independent
ambulation with KAFO (most likely needed due to iliopsoas
weakness as innervated by L2 nerve root) at household
distance (due to high energy costs)
L4: independent ambulation with AFO (LMN lesion resulting
in ankle DF and anterior tibialis weakness -> foot drop) in
community

Posterior trim lines for TLSO?
Anterior trim lines for TLSO? - CORRECT ANSWER
>>>>Posterior: Inferior to spine of scapula to sacrococyggeal
Anterior: Inferior to sternal notch symphysis pubis
What pathology would indicate use of Williams flexion LSO?
- CORRECT ANSWER >>>>Spondylolisthesis - Williams
Flexion LSO allows free lumbar flexion but stops lumbar
extension making it a possible orthosis for spondylolithesis
management
The "unhappy triad" includes injury to the following
structures: - CORRECT ANSWER >>>>ACL, MCL, and medial
meniscus
From forces that cause genu valgum, flexion, and external
rotation applied to the knee when the foot is planted
A patient has bilateral pars fractures at L5 and is currently in
a custom polymer overlapping style LSO with decreased
lumbar lordosis. Physician wants to further immobilize the
fracture site; what do you use? - CORRECT ANSWER
>>>>Add a hip spica to the LSO- allows how much hip flexion
and extension is allowed, which can further immobilize the
patient
