Question 1

A halo vest is indicated primarily for which of the following scenarios?

Accepted Answer

Unstable cervical fracture or post-surgical cervical fusion requiring rigid immobilization

Answer

The halo vest provides the most rigid cervical immobilization available and is used for unstable cervical fractures or following complex cervical spine surgeries.

Question 2

Which cervical orthosis provides the least restriction of cervical range of motion?

Accepted Answer

Soft foam cervical collar

Answer

A soft foam cervical collar provides primarily proprioceptive feedback and warmth with minimal mechanical restriction of cervical motion.

Question 3

The SOMI (Sterno-Occipital-Mandibular Immobilizer) orthosis is best described as:

Accepted Answer

A cervicothoracic orthosis that controls upper cervical flexion effectively without a posterior upright

Answer

The SOMI brace uses sternal, occipital, and mandibular supports to control upper cervical flexion and is notable for lacking a posterior thoracic upright.

Question 4

For a patient with osteoporotic vertebral compression fracture at T8, which orthosis best combines fracture stabilization with ease of donning?

Accepted Answer

Cruciform Anterior Spinal Hyperextension (CASH) orthosis

Answer

The CASH orthosis uses sternal and pubic pads connected by a frame to prevent flexion with a simple anterior-only design that is easy for elderly patients to don.

Question 5

The Milwaukee brace differs from the Boston brace primarily because it:

Accepted Answer

Extends superiorly to include a cervical ring and throat mold for high thoracic curves

Answer

The Milwaukee brace includes a neck ring and throat mold extending above the TLSO foundation, making it suitable for scoliotic curves with an apex at or above T8.
