Orthopaedic x-ray ruler

An orthopaedic x-ray ruler is a precision tool used during fluoroscopy to measure bone dimensions accurately. Surgeons rely on it to assess length, thickness, or alignment of bones in real-time, ensuring proper placement of implants or surgical adjustments.

These devices are typically reusable and designed to be clearly visible on x-ray images, often made from materials like stainless steel. Regulation varies by jurisdiction, but they are generally classified based on their intended use and risk level in surgical settings.
