MR imaging in femoroacetabular impingement
نویسنده
چکیده
Femoroacetabular impingement (FAI), sometimes termed acetabular rim syndrome, results from chronic mechanical abutment between the femoral head-neck junction and the acetabulolabral complex. Orthopedists have begun to recognize FAI as a cause of pain, instability and progressive hip dysfunction. Because FAI is implicated in the development of osteoarthritis in young individuals, orthopedists have increasingly utilized imaging to support their clinical diagnoses and treatment decisions. Whereas conservative treatments are considered unsuccessful, many surgical procedures remain controversial. If FAI can be diagnosed in its early stages, surgical procedures may prove to be effective in correcting the anatomical deformities that cause femoroacetabular impingement and, therefore, in limiting the degenerative process and delaying joint replacement.

OBJECTIVE To determine the sensitivity and accuracy of direct MR arthrography in the diagnosis of intra-articular lesions associated with femoroacetabular impingement. MATERIAL AND METHODS We used direct MR arthrography to study 51 patients with femoroacetabular impingement who underwent arthroscopic hip surgery. Surgery demonstrated 37 labral tears, 44 lesions in the labral-chondral transiti...

A mechanistic link has been suggested between cam-type femoroacetabular impingement and increased stress on the symphysis pubis. This retrospective study was conducted to determine whether there is an increased prevalence of osteitis pubis, as evidenced by imaging, in patients with femoroacetabular impingement compared with age-matched control subjects. Search of a radiologic database of a larg...

OBJECTIVE The purpose of this article is to show the important radiographic criteria that indicate the two types of femoroacetabular impingement: pincer and cam impingement. In addition, potential pitfalls in pelvic imaging concerning femoroacetabular impingement are shown. CONCLUSION Femoroacetabular impingement is a major cause for early "primary" osteoarthritis of the hip. It can easily be...
