How can you differentiate a mild sprain from a fracture in the field?

• A. Fractures often cause deformity, swelling, crepitus, and inability to move the limb; sprains have pain and swelling but no deformity.
• B. Sprains always involve bone displacement.
• C. Fractures never cause swelling.
• D. Sprains always result in deformity.

Answer: (C)

When distinguishing a fracture from a mild sprain in the field, look for signs that involve bone and alignment. Fractures often show deformity or abnormal alignment of the limb, possible crepitus with movement, noticeable swelling, and an inability to move or bear weight. Sprains, on the other hand, usually cause pain and swelling but the limb remains in normal alignment without bone crepitus. Keep in mind that non-displaced fractures may not look deformed, so assess tenderness along the bone, and always check distal circulation, sensation, and movement. If deformity, inability to move, or suspected fracture is present, immobilize with a rigid splint and transport for medical care.
