| navicular fracture | <orthopaedics> A fracture of the scaphoid (navicular) bone in the wrist. The most common method of injury is a fall on an outstretched hand in an adult. In children, this same type of fall more commonly results in a Colles fracture. (27 Sep 1997) |

| neurogenic fracture | A fracture in bone weakened by disease of the nerve supply. (05 Mar 2000) |
| strain fracture | The tearing off, by a sudden force, of a piece of bone attached to a tendon, ligament, or capsule; the force may be exogenous or endogenous. (05 Mar 2000) |
| stress fracture | <orthopaedics, radiology> A hairline or microscopic break in the bone that is not demonstrable with conventional X-rays. Symptoms include a dull aching pain with tenderness at the site. Symptoms often increase with activity and diminish with rest.

Although they may occur in most any location, they are most common in the tibia, fibula and metatarsal bones. (27 Sep 1997) |
