- Fatigue fracturealso known as stress fracture
Fatigue fracture is characterised by incomplete interruptions in the bone tissue, sometimes when a fracture is present. It is a result of small injuries from unaccustomed stress and is accompanied by bone regeneration.
1. So-called permanent fracture to the healthy skeleton, mostly as a single incomplete fracture, e.g. clay shovellers' fracture, cough fracture; 2. With the formation of so-called transformation zones in the diseased skeleton, usually multiple, e.g. Looser transformation zones. Occurs for instance in the milkman syndrome.
Sudden pain, often wrongly felt to be rheumatism, raised sensitivity to stress, sometimes local reddening, overheating, swelling. Insidious and chronic pain in the transformation zones.
It is often not possible to recognise the site of the fracture immediately in the X-ray. A reliable diagnosis is possible with nuclear spin tomography. Otherwise look for local regeneration of bone. This is the so-called callus, which may take the form of a band of osteosclerosis.
Treatment: conservative (without an operation).
