Which imaging technique is primarily used to determine if a bone is broken or fractured?

Radiography is the primary imaging technique used to determine if a bone is broken or fractured due to its ability to provide clear images of the skeletal structure. This method utilizes X-rays, which are effective in penetrating through soft tissues and highlighting denser materials like bone. The resulting images allow medical professionals to visualize fractures, dislocations, and other abnormalities in bone structure accurately.

While a CT scan also provides detailed images and can help detect complex fractures, it is used less frequently as a first-line diagnostic tool compared to radiography. MRI, on the other hand, is typically more valuable for assessing soft tissues, such as ligaments and cartilage, rather than for diagnosing bone fractures. Arthroscopy is an invasive procedure used primarily for direct visualization and treatment of joint issues, not for initial bone fracture assessment. Thus, radiography remains the go-to imaging technique for identifying broken or fractured bones.
