Abstract
Chronic hip pain is a common problem in the adults. It
can be caused by numerous causes including occult trauma,
infection, arthropathies, neoplasms, avascular necrosis,
transient osteoporosis, or other causes.
Clinical data play an important role in evaluation of
chronic hip pain. Routine radiographs are essential to plan
further imaging studies. MRI, CT, ultrasonography, and
radionuclide scans may all be used as second technique
(Berquist et al., 2000).
The imaging pathway for hip pain has evolved
considerably with the advent of MRI. The latter has supplanted
bone scintigraphy as the investigation of choice when occult
fractures, bone marrow edema syndromes or avascular necrosis
are suspected. MRI is also invaluable for evaluating synovial
proliferative disorders of the hip such as pigmented villonodular
synovitis and synovial osteochondromatosis. Furthermore by
combining joint distension with multiplanar imaging, MR
arthrography (MRA) allows detailed assessment of the
acetabular labrum and cartilage (Fang and Teh, 2003).
CT still has a lot to offer in musculoskeletal work, being
the best modality for examining cortical bone, and remaining
the cross-sectional imaging technique of choice where MRI is
unavailable or cannot be performed, for example in
claustrophobic patients or those fitted with cardiac pacemakers
(Grainger and Allison, 1997).
CT has a key role in delineating fractures and assessing
the bony architecture of the hip (Fang and Teh, 2003).
