"A pathological fracture, although a type of insufficiency fracture, is a term in general reserved for fractures occurring at the site of a focal bony abnormality. Some authors use the term stress fracture synonymously with fatigue fracture, and thus caution is warranted with the term."

"Stress fractures are far more common in the lower limb (~95%) than in the upper limb 5. High-risk sites of stress fractures are locations at greatest risk of a progression to complete fracture, displacement or non-union as these sites are under tensile stresses and have poor vascularity 9-11:"

"Stress fractures on bone scintigraphy appear as foci of increased radioisotope activity ('hot spot') due to increased bone turnover at the site of new bone formation. However, as with all bone scintigraphy, this is non-specific; the increased uptake can also be due to osteomyelitis, bone tumours or avascular necrosis."
