Case Discussion
It is important to distinguish acute from chronic Jones fractures, because chronic cases may present as stress fractures at a later stage. Stress fractures usually have poor prognosis for healing.
Chronic Jones fractures show non-union with adjacent medullary sclerosis. However the medullary canal can be obliterated as well.
