Answer:**A** = used over joints or bandaging around a joint which is a junction of 2 axes (e.g. the shoulder is the junction between the appendicular axis and the axial axis) **B** = circular roll is indicated as a usual technique in injured limbs, used over a tubular area like the **arm or leg** **D** - Spiral (or reverse spiral) bandage is a technique used for **application of compression bandaging**
75
A patient who has an **injury of the proximal interphalangeal joint on her ring finger** from a basketball game will benefit with: a. Short arm splint b. Long arm splint c. Ulnar gutter splint d. Buddy Taping
Answer: **D** = immobilizing the fingers; this type is **less rigid and will permit some motion in flexion and extension**. It will need the adjacent LONGER DIGIT as its buddy **A** - Short-arm splint: Spans from the **knuckles and distal palmar** crease distally up to 4 cms. from the cubital fossa proximally **B **- Long-arm splint: Spans from the **knuckles and distal palmar **crease distally up to 4 cms. below the axilla proximally **C **- Ulnar gutter splint: flexible splint that is used to **support, stabilize, and immobilize injuries, dislocations** and fractures of the hands, fingers, or wrists (not mentioned in lecture)
