Evaluation of the triangular fibrocartilage: comparison of two-compartment wrist CT arthrography using the distal radioulnar and radiocarpal joints and unicompartment wrist CT arthrography using the radiocarpal joint

초록

Objective: To compare the diagnostic performance of two-compartment wrist CT arthrography of the distal radioulnar and radiocarpal joints and unicompartment wrist CT arthrography of the radiocarpal joint in depiction of the triangular fibrocartilage tear. Methods: From January 2016 to December 2017, two-compartment CT arthrography of 74 consecutive patients (36 females, 38 males: mean age, 37.2 years) and unicompartment CT arthrography of 51 consecutive patients (18 females, 33 males: mean age, 40.1 years) were obtained. All CT arthrography images were independently and blindly evaluated by two radiologists for the presence of the triangular fibrocartilage tear by grade (partial or kill thickness) per its locations: central disc proper, central-peripheral junction, proximal and distal laminae of its ulnar attachment. Fisher's exact test was used for a statistical analysis, and a p-value less than 0.05 was considered as significant. The arthroscopic findings of 47 patients (34 patients with two-compartment CT arthrography and 13 patients with unicompartment CT arthrography) were evaluated for calculating sensitivity, specificity, and accuracy. Results: All partial and full thickness triangular fibrocartilage tears were identified more commonly by their location except for distal laminae on two-compartment CT arthrography than were unicompartment CT arthrography (p = 0.001-0.022). Two-compartment CT arthrography had high sensitivity (90.9-100%) and low specificity (33.3-76.5%) for detecting central disc proper and proximal lamina tears, comparing with unicompartment CT arthrography. Conclusion: Two-compartment wrist CT arthrography is more helpful for detecting triangular fibrocartilage tears than unicompartment wrist CT arthrography. The aim of the study was to determine the effects of 12 weeks aerobic training with a diet regimen on glycemic control and cardiovascular health of boys with T1DM. The participants (N = 20) were distributed equally into an intervention group (IG) and control group (CG). The IG received 50-minute exercise sessions, thrice a week, with a diet regimen. The CG received their usual care. Body mass, body mass index (BMI), resting heart rate, blood pressure, blood lipids, fasting blood glucose, and HbAlc were measured at baseline and post- intervention. The Shapiro-Wilk test was performed before analyzing the data with parametric or non-parametric tests. Differences of p <= 0.05 and effect size (ES) >= 0.2 were considered significant. There were no differences in HbAlc between the IG and CG at baseline (10.3% (0.9) vs 10.3% (1.2), respectively, p = 0.9353). Mean HbA1c of the IG was lower than that of the CG after the intervention (9.6% vs. 11.4%; p = 0.012, 95% CI = 0.5 to 3.1, ES = 1.36). Resting heart rate, systolic blood pressure, total cholesterol, and fasting blood glucose were better in the IG than the CG after 12 weeks (p < 0.05, ES 0.2). Thus, there is evidence that aerobic training with a diet regimen improves the glycemic control and cardiovascular health of boys with T1DM in 12 weeks.
