Manipulation of a fracture is best described as which of the following?

Manipulation of a fracture is best described as a non-invasive manual procedure. This term refers to a method where a healthcare provider applies manual techniques to realign the fractured bone without the need for surgical incisions. This typically involves physically adjusting the position of the bone ends to promote proper healing.

Non-invasive manual procedures such as these are essential in managing fractures, especially when the bones can be aligned without the need for surgical intervention. It is often performed under sedation or anesthesia, but there is no requirement for cutting into the skin or operating through an incision, which distinguishes it from invasive surgical methods.

In contrast, other options like invasive surgery, radiation treatment, and surgical incision involve more aggressive techniques and may require significant medical intervention. Invasive surgery would involve opening up the body to repair the fracture, while radiation treatment is used for other conditions and does not manipulate bones directly. A surgical incision comprises a cut made during surgical procedures, which is not applicable in the context of simple manipulation of a fracture.
