Question: 1 / 195

In orthopedic terminology, what does 'nonunion' refer to?

A successful healing of a fracture

A failure of fracture ends to heal appropriately

In orthopedic terminology, 'nonunion' specifically refers to the failure of the ends of a fractured bone to heal together appropriately. This condition can occur for various reasons, including inadequate blood supply, infection, instability at the fracture site, or insufficient immobilization. When a fracture does not heal successfully, it can lead to ongoing pain, mobility issues, and other complications.

Differentiating from the other options, successful healing of a fracture would indicate proper union, while surgical fixation and methods of fracture reduction are interventions aimed at ensuring healing occurs. Nonunion is primarily a complication that indicates that these interventions may not have succeeded, making understanding its implications critical for managing orthopedic injuries effectively.
