OCC OCC Fracture Types & Casting Indications 2

Question 1

A Jones fracture is located at which anatomical site?

Accepted Answer

Base of the fifth metatarsal at the metaphyseal-diaphyseal junction

Answer

The Jones fracture occurs at the proximal fifth metatarsal junction, where poor vascularity makes healing difficult and often requires non-weight-bearing casting.

Question 2

Which fracture results from repetitive loading rather than acute trauma?

Accepted Answer

Stress fracture

Answer

Stress fractures develop from cumulative microtrauma — such as repetitive impact in athletes — rather than a single traumatic event.

Question 3

A torus (buckle) fracture is most commonly seen in which population?

Accepted Answer

Children under 10 years old

Answer

Torus fractures occur in pediatric bone where the cortex buckles under compression without complete cortical breach, typical of falls onto an outstretched hand.

Question 4

What is the primary contraindication for closed casting of an open (compound) fracture?

Accepted Answer

High infection risk requires wound management before casting

Answer

Open fractures carry high infection risk; wound irrigation, debridement, and often surgical fixation are performed before any definitive cast application.

Question 5

A long arm cast is indicated instead of a short arm cast for which type of fracture?

Accepted Answer

Both-bone forearm fracture (radius and ulna) requiring rotational control

Answer

Both-bone forearm fractures require elbow immobilization to control forearm rotation, which a short arm cast cannot provide.
