What is a potential complication of untreated fractures?

A potential complication of untreated fractures is infection or compromised blood supply. When a bone is broken, the surrounding tissue, including blood vessels, can be damaged. If proper treatment is not administered, this can lead to inadequate blood flow to the area, hindering healing and increasing the risk of necrosis. Additionally, fractures that penetrate the skin create an open wound, making it susceptible to infections from bacteria and other pathogens. Proper immobilization and medical attention are essential not only to aid in healing but also to minimize these risks.

The other options do not accurately represent complications associated with untreated fractures. Increased flexibility in the limb would typically not occur; rather, a fracture may lead to stiffness and restricted movement. Loss of muscle strength can occur as a consequence over time due to disuse but is not an immediate complication of the fracture itself. Improved bone density is unlikely as fractures usually indicate a weakness in the bone, and unless treated and managed properly, the overall condition may not improve.
