This retrospective study evaluated the diagnostic value of computed tomography in patients with sacroiliac pain. Computed tomography scans of the sacroiliac joints of 62 patients with sacroiliac joint pain were reviewed. The criteria to include the patient in the current study were pain relief after a local injection in the sacroiliac joint under computed tomography guidance, a physical examination consistent with a sacroiliac origin of the pain, and negative magnetic resonance imaging of the lumbar spine. ⋯ The sensitivity of computed tomography was 57.5 % and its specificity was 69%. The finding of the current study suggests limited diagnostic value of computed tomography in sacroiliac joint disease because of its low sensitivity and specificity. With clinical suspicion of a sacroiliac origin of pain, intraarticular injection is currently the only means to confirm that diagnosis.

Comparative StudyPerceptions of outcomes after unicompartmental and total knee replacements.
An independent measurement of the quality of outcome of 31 consecutive Oxford medial unicompartmental knee replacements in 28 patients and 130 total knee replacements in 104 patients performed between 1993 and 1997 is reported. The indications for surgery were anteromedial osteoarthritis for unicompartmental replacement and more extensive osteoarthritis for total knee replacement. All patients were treated by one surgeon. ⋯ The tibial component of one total knee replacement appeared loose, but the patient had no symptoms. In comparison with total knee replacement, implantation of meniscal bearing unicompartmental replacement technically is demanding and unforgiving. However, revision of a failed Oxford unicompartmental replacement is easier than revision of a failed total knee replacement, and the authors recommend this device for younger patients in whom one could expect a total knee replacement to fail within their lifetime.
