Conclusion
Stress fractures in lower extremities predominantly involve the metatarsals,
tibia and spine Pelvic stress fractures come next and are usually located at the pubis,
sacrum or femoral neck.
Acetabular stress fractures are rare and therefore unrecognized,
but do occur and may be a cause for activity-related hip pain
Isolated fractures of the cuneiforms are extremely rare,
accounting for only 1.7% of all midfoot fractures.When cuneiform fractures do occur,
they are often in conjunction with other injuries,
such as fractures to the adjacent cuneiforms,
or are a part of a greater injury complex,
such as Lisfranc fracture dislocations. Isolated medial cuneiform fractures are extremely rare
Bone scintignaphy is thought to be useful in distinguishing the bone mesponse to stress (ie,
accelerated memodeling and fatigue) from actual fracture and thus may also be useful in defining a vulnerable period of cortical weakening and incipient fracture.
It remains to be shown whether the marrow changes seen on MR images reflect similar pathophysiotogic processes.
The efficacy of MR imaging in the detection of focal,
acceterated bone resorption in transient osteoporosis is evolving.
MR imaging may prove equally sensitive when compared with bone scintigraphy in the early phase of evolving stress fracture,
while providing more specific diagnostic information.
