Orthopaedic Technologist Certification Flashcards

Which type of cast is most appropriate for a stable distal radius fracture requiring immobilization of the wrist while allowing elbow motion?

Answer: Short arm cast

A short arm cast extends from below the elbow to the metacarpal heads, immobilizing the wrist while leaving the elbow free.

When applying a fiberglass cast, the OT should wear gloves primarily to:

Answer: Protect against dermatitis from the resin

Fiberglass casting tape contains resin that can cause contact dermatitis with prolonged skin exposure, making glove use essential.

A patient presents with a suspected scaphoid fracture but initial X-rays are negative. The most appropriate next step is:

Answer: Apply a thumb spica splint and arrange follow-up imaging

Scaphoid fractures are frequently occult on initial radiographs; thumb spica immobilization is initiated and MRI or repeat X-rays at 10-14 days are recommended.

Compartment syndrome is BEST assessed by evaluating which of the following?

Answer: Pain with passive stretch, paresthesia, and compartment pressure

The classic assessment of compartment syndrome includes pain out of proportion, pain with passive stretch, paresthesia, and direct compartment pressure measurement.

Which traction type applies force directly through surgically implanted pins or wires into bone?

Answer: Skeletal traction

Skeletal traction uses pins or wires placed directly into bone to apply and maintain traction force, unlike skin traction which acts on soft tissue.

When measuring for axillary crutches, the armrest should be positioned approximately:

Answer: 1-2 inches below the axilla

Axillary crutch pads should rest 1-2 inches (2-3 finger widths) below the axilla to prevent brachial plexus compression.

Which gait pattern is used when a patient can bear partial weight on one extremity and uses two crutches?

Answer: Three-point gait

Three-point gait involves advancing both crutches together with the affected limb, then swinging the unaffected limb forward, used for partial or non-weight-bearing.
