In the Ottawa ankle rules, tenderness over which area necessitates an X-ray?

The Ottawa ankle rules are a clinical guideline used to determine the need for X-rays in patients with ankle injuries, primarily focused on assessing the presence of fractures. In this context, if there is tenderness over the distal fibula, it indicates that there is a possibility of a fracture, which justifies imaging to rule out such an injury.

Tenderness in the distal fibula is particularly relevant because the fibula is a key bone in the ankle's stability. Fractures in this area can significantly affect a person's mobility and weight-bearing ability. The rules specify that tenderness over this specific location warrants further investigation, as it helps clinicians identify potentially serious injuries that may impact treatment plans.

The other areas mentioned, such as the proximal fibula, distal femur, and midfoot, do not follow the same protocol under the Ottawa ankle rules regarding ankle injuries. Therefore, focusing specifically on the distal fibula is essential for making informed decisions about necessary imaging after assessing a patient's ankle injury.
