OTC Orthopaedic Technologist Certified Lower Extremity Splinting 2 — Questions and Answers
Question 1: When applying a posterior ankle splint, what is the correct foot position to maintain?
- Plantar flexion at 30 degrees
- Neutral position (90 degrees dorsiflexion) (Correct answer)
- Full dorsiflexion
- Inversion with slight plantar flexion
Correct answer: Neutral position (90 degrees dorsiflexion)
Neutral position (90-degree dorsiflexion) prevents equinus contracture and maintains proper tendon and joint alignment.
Question 2: A patient presents with a suspected Jones fracture. Which splint is most appropriate for initial management?
- Long leg posterior splint
- Short leg posterior splint with U-slab (Correct answer)
- Knee immobilizer
- Stirrup (sugar tong) ankle splint
Correct answer: Short leg posterior splint with U-slab
A short leg posterior splint with a U-slab (stirrup) provides circumferential support and immobilization appropriate for Jones fractures at the base of the fifth metatarsal.
Question 3: How many layers of cotton padding should be applied over bony prominences when splinting the lower extremity?
- Same as surrounding areas
- One layer less than surrounding areas
- Extra padding — double or more layers (Correct answer)
- No padding is needed over bony prominences
Correct answer: Extra padding — double or more layers
Bony prominences require extra padding to prevent pressure sores and skin breakdown under the rigid splint material.
Question 4: Which complication is specifically associated with a splint that is applied too tightly after an acute lower extremity injury?
- Deep vein thrombosis
- Compartment syndrome (Correct answer)
- Avascular necrosis
- Reflex sympathetic dystrophy
Correct answer: Compartment syndrome
Compartment syndrome occurs when swelling within a tight compartment increases pressure enough to compromise neurovascular supply.
Question 5: When measuring plaster splint material for a posterior short leg splint, how wide should the plaster typically be?
- 2 inches
- 3 inches
- 4 to 5 inches (Correct answer)
- 6 to 8 inches
Correct answer: 4 to 5 inches
A 4- to 5-inch wide plaster slab is standard for short leg posterior splints to provide adequate support without excessive bulk.
Question 6: A posterior long leg splint should extend from the proximal thigh to the:
- Ankle joint only
- Base of the metatarsals
- Toes (metatarsophalangeal joints) (Correct answer)
- Mid-foot
Correct answer: Toes (metatarsophalangeal joints)
A long leg posterior splint should extend to the toes to provide full immobilization and prevent distal motion.
Question 7: Which neurovascular check finding is MOST concerning immediately after applying a lower extremity splint?
- Mild warmth over the splint
- Capillary refill of 2 seconds
- Inability to wiggle toes with increasing pain (Correct answer)
- Slight swelling at the distal foot
Correct answer: Inability to wiggle toes with increasing pain
Inability to move the toes combined with increasing pain signals possible neurovascular compromise or evolving compartment syndrome requiring immediate evaluation.
