In fracture repair, what biomechanical effect does a tension-band technique produce?
Correct answer: C. Converts tensile force into compression
- A. Converts compression into distraction
- B. Eliminates all rotational forces
- C. Converts tensile force into compression
- D. Prevents blood supply to the bone
Explanation
A tension-band construct converts distracting tensile forces on the convex side of a fracture into compression at the fracture line. It does not automatically eliminate rotation or intentionally compromise bone blood supply.
