Something like this type of stress factor is often seen in regular runners who average more than 15 miles per week. Frequently being seen in the smaller bones of the feet (as the tarsals/metatarsals) , this type of repetitive motion injury can create a chronic state of fracture and inflammation, usually requiring a reduction in either/both frequency or duration of the activity. This may require runners to alternate running with walking, and limit running to grass surfaces or indoor treadmills with suspended roller treads to cushion impact to the feet. Additional cushioning within the shoe can help, or customized orthotics if fallen arches are a contributing factor. Aerobics must be limited to low-impact movements that do not require jumping, as this can magnify the force of stress to the feet by 300% actual body weight (remember E=mc2 !).
An acute fracture is a break in a bone that occurs quickly, rapidly and usually traumatically. A non-acute fracture is one that occurs over time, often because of repeated physical stress or impact placed on the bone.

The prognosis for minor pelvic fractures is excellent, with most people gaining full mobility in a matter of weeks or months.
A pathologic fracture occurs when a weakened bone breaks under normal strain.
A Colles' fracture is typically associated with osteoporosis. The fracture occurs in the forearm and is also called a "dinner fork" fracture.
Bleeding occurs at the fracture site and a blood clot forms.
The medical terminology for this is a "stress fracture".stress fracturestress fracture
