Key Medical Takeaway

We review everything you need to understand about ORTHOPEDIC MCQS ONLINE QUESTION BANK H1C. Fractures arise from either a single, acute force—such as a pure torsional humerus break—or repetitive loading, causing stress fractures like metatarsal or femoral neck injuries. Understanding each scenario l h is vital, as fracture site blood flow critically peaks at two weeks post-injury for healing. The nutrient artery primarily supplies the inner cortex, a supply capable of being compromised by interventions like intramedullary reaming.

QUESTION 1

**ORTHOPEDIC MCQS ONLINE QUESTION BANK H1C**
Which of the following fractures occurs through a single application of force :

A minimally displaced femoral neck fracture in a long distance runner

A fifth rib fracture in a collegiate rower

A second metatarsal fracture in a Naval Academy midshipman

A proximal one-third posterior tibial cortex fracture in a long distance runner

A short spiral humerus fracture in a baseball catcher The femoral neck fracture, metatarsal fracture, rib fracture, and the tibial fracture are stress fractures that result from repetitive loading. In contrast, the humeral fracture in the baseball catcher is secondary to failure of the humerus secondary to a pure torsional force. Long bones are at their weakest when loaded in pure torsion.
