OTC Orthopaedic Technologist Certified Lower Extremity Splinting 3

Question 1

What is the primary purpose of bivalving a lower extremity splint or cast?

Accepted Answer

To relieve pressure from swelling and prevent compartment syndrome

Answer

Bivalving cuts the cast or splint on two sides to relieve constriction caused by swelling, reducing the risk of compartment syndrome.

Question 2

When applying a fiberglass splint to the lower extremity, gloves should be worn primarily to:

Accepted Answer

Prevent skin irritation and allergic contact dermatitis from uncured fiberglass resin

Answer

Uncured fiberglass resin can cause contact dermatitis in both the patient and the technologist, making glove use essential.

Question 3

A 'stirrup' or 'sugar tong' ankle splint applies padding and plaster in what configuration?

Accepted Answer

Medial-plantar-lateral U-shaped configuration around the ankle

Answer

The stirrup splint forms a U-shape going from the medial lower leg, under the heel, and up the lateral lower leg, limiting inversion and eversion.

Question 4

What water temperature is recommended when dipping plaster of Paris splint material?

Accepted Answer

Room temperature to lukewarm water (21–27°C)

Answer

Room temperature to lukewarm water allows adequate working time; hot water accelerates setting too quickly and can cause thermal burns.

Question 5

A calcaneal fracture splint should position the foot in which configuration?

Accepted Answer

Neutral dorsiflexion with slight eversion

Answer

Neutral dorsiflexion with slight eversion maintains optimal alignment and reduces tension on the calcaneal fracture site.
