A bone contusion, commonly known as a bone bruise, occurs when a bone experiences trauma but does not fracture. This injury results in bleeding and swelling within the bone tissue, leading to pain and tenderness in the affected area. Bone contusions are often caused by direct impact, such as a fall or a collision during sports activities. Diagnosis typically involves imaging techniques like MRI or X-rays, which can reveal the extent of the injury. Treatment usually includes rest, ice, compression, and elevation (RICE) to reduce swelling and pain. Most bone contusions heal on their own over time, but severe cases may require medical intervention.
