Most bone, muscle and joint injuries are caused by sudden impact of some type, this type of injury is often determined by the physical mechanism of injury and therefore it is useful to gain as much information about the incident as possible so to pass onto medical services to enable them to treat the casualty efficiently. Unless the skin is broken and a broken bone is clearly visible it is difficult to determine what injury the casualty has actually received.
Some of the signs to look out for are:
- History of a recent blow or fall
- Sound of snapping from the injury site
- Difficulty in moving the limb
- Severe pain and tenderness over the site of the injury
- Distortion and/or swelling
- Bruising
- Signs of shock if the injury is severe
