Which fracture results from twisting injuries?

• A. Transverse Fracture
• B. Stress Fracture
• C. Dislocation
• D. Spiral Fracture

Answer: (D)

Twisting injuries apply a rotational force to a long bone, causing it to fail in a spiral pattern. The resulting fracture line winds around the shaft, reflecting the torsional stress as the bone twists while breaking. This is what makes a spiral fracture the typical outcome of a twisting force. In contrast, a transverse fracture results from direct impact or loading that causes a clean break straight across the bone, a stress fracture comes from repetitive submaximal loading over time, and a dislocation involves the joint surfaces losing their normal alignment rather than a crack through the bone itself.
