To review about the undiagnosed and unrecognised stress fractures like,
Acetabular stress fractures which are rare and therefore unrecognized,
but do occur and may be a cause for activity-related hip pain.
Also to review about the isolated cunieform stress fractures which are extremely rare and unrecognised.
To Substantiate the Role of MRI in early diagnosis of both common stress fracture sites and rare sites which are unrecognised .
A stress fracture is the result of repetitive,
prolonged muscular action on a bone that has not accommodated itself to that action.
stress fractures occur in non-weight-bearing bones and showed that stress fractures do not result from impact on a bone.
In most instances,
persons who have stress fractures are engaged in vigorous activity that is either totally new or to which they have not yet become conditioned.
From an etiologic standpoint,
two types of stress fractures are encountered: fatigue fractures and insufficiency fractures.
Findings and procedure details
Savoca  described stress fractures as compression or distraction fractures.
Compression fractures generally occur in cancellous bone such as the neck of the femur,
the proximal shaft of the tibia,
and the calcaneus.
Distraction fractures occur more commonly in compact bone.
The exact radiologic appearance,
depends on the amount of time between the onset of injury and the imaging examination andon whether the patient continued participation in the activitydespite pain.
In the early phase,

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,
