Secondly, the protracted chronic application of abnormal stresses (e.g. Most commonly fractures occur in the setting of a normal bone with acute overwhelming force, usually in the setting of trauma. J Neurosurg Spine. Despite what should be a simple entity, controversy exists, as well as confusion in the literature, with the term Jones fracture sometimes liberally (and incorrectly) applied to this fracture. Radiographically Occult and Subtle Fractures: A Pictorial Review. At the end of this process, which usually takes approximately a week, a primary callus (also known as soft-tissue callus, or procallus) is present which is non-mineralized and not readily visible on radiography 1. It is also known as backfire fracture or lorry driver fracture 1. Treatment can be bracing or, more typically, internal fixation. It is also relatively common among tennis players, accounting for it sometimes being referred to as a "tennis fracture".

Some authors use the term stress fracture synonymously with fatigue fracture, and thus some caution with the term is suggested. Fractures will appear as discontinuities in the bone and may or may not be displaced. Rarely, a torus fracture may refer to the fracture of an oral torus, and there is potential for the two terms to be confused 10. Several advantages of CT includes: short acquisition time, ability to acquire volumetric image of the bone, with good spatial resolution. Stress fractures normally present with worsening pain with a history of minimal or no trauma.
