Accuracy of direct magnetic resonance arthrography in the diagnosis of triangular fibrocartilage complex tears of the wrist.

The aim of this study was to assess the value of direct magnetic resonance (MR) arthrography of the wrist for detecting full-thickness tears of the triangular fibrocartilage complex (TFCC). Twenty-four consecutive patients who had ulnar-sided wrist pain and clinical suspicion of TFCC tear were included in the study. All patients underwent direct MR arthrography and then wrist arthroscopy, and the results of MR arthrography were compared with the arthroscopic findings. The positive predictive value of MR arthrography in detecting TFCC full-thickness tear was 0.95, and the negative predictive value was 0.50. The sensitivity of MR arthrography in detecting a TFCC full-thickness tear was 74% (15/19), and specificity was 80% (4/5). The overall accuracy of MR arthrography in detecting a full-thickness tear of the TFCC in our study was 79% (19/24). We believe that diagnosis of tears in the TFCC by direct MR arthrography is not entirely satisfactory, although MR arthrography has a high positive predictive value for detecting TFCC tears. Negative results of MR arthrography in patients with clinical suspicion of TFCC tear should be interpreted with caution.

Pyrexia following total knee replacement.

This study aims to determine the incidence and factors associated with pyrexia following total knee replacement (TKR). We performed a retrospective analysis of the temperature charts and histories of patients who underwent 170 TKRs. There was a statistically significant increase in mean temperature from pre-operation to post-operation, and this increase remained significant through to 5 days post surgery (p<0.0001). Sixty-two (36.5%) patients were pyrexial (>or=38 degrees C) at some point. Fourteen patients developed a clinical infection, but only four of these were pyrexial. There was no association between pyrexia and infection, allogenic blood transfusion, haemoglobin loss, use of urinary catheter, rheumatoid arthritis, anaesthetic type, and previous pyrexia following TKR. Pyrexia as a diagnostic test for the development of infection had a sensitivity of 0.286 (95% CI=0.084-0.581), specificity of 0.628 (95% CI=0.548-0.704) and positive predictive value of 0.065 (95% CI=0.018-0.157). Pyrexia in the first 5 days following TKR is usually a normal physiological response and should not cause undue concern about the presence of infection.
