Reconstruction of scaphoid waist non-unions using a radial approach: Preliminary outcome analyses.

This study aimed to evaluate clinical and radiographic outcomes in a consecutive series of patients who underwent open surgery via a radial approach for reconstruction of scaphoid waist non-union. Over a 2-year period, 16 males with scaphoid waist non-union received surgery using a radial approach; we performed limited styloidectomy, biconcave curettage, ovoid bone grafting from the styloidectomy fragment, and placement of a retrograde radial-entry screw. Mean patient age was 25.1 years (range 17-56 years). Bony union was determined on radiographs and computed tomography. Radiographic variables were measured on preoperative and final follow-up radiographs. Mean follow-up was 14 months (range 8-19 months). Subjective and objective outcomes were recorded. Radiographic healing was achieved in 14 of the 16 patients (88%) at a mean 4½ months after surgery (range 3-6 months). Significant postoperative improvements were found in mean carpal height ratio (from 0.48 to 0.53) and radiolunate angle (from 8.2° to 2.8°) compared to preoperative data. Mean postoperative wrist extension was 54° (range 32-67°) and mean flexion 49° (range 2-64°). Mean flexion arc after surgery was 84.1% that of the contralateral side. Mean grip strength was 85.2% that of the contralateral side. Subjective results comprised mean postoperative Modified Mayo Wrist score of 82.3 (range 55-90) and Quick Disabilities of the Arm, Shoulder and Hand score of 11.2 (range 0-36.4). Twelve of the 14 healed wrists were subjectively rated as good or excellent. Repair of scaphoid non-union via a radial approach was safe and effective. Union rates were high and outcomes were good.

Impact of right ventricular diastolic dysfunction on clinical outcomes in inferior STEMI.

BACKGROUND: The aim of this study was to investigate the prognostic value of restrictive right ventricular filling pattern (RRVFP) in patients with the first acute inferior wall myocardial infarction (IWMI) complicated by right ventricular myocardial infarction (RVMI) undergoing primary percutaneous coronary intervention (p-PCI). METHOD: A total of 152 patients with acute IWMI complicated by RVMI undergoing p­PCI were divided into two groups according to the presence of RRVFP. RRVFP was defined as tricuspid diastolic early/late flow velocities (Et/At) > 2 and Et deceleration time (DT) < 120 ms. RESULTS: There were 23 patients with RRVFP in the study cohort. At, DTt, isovolumetric relaxation time (IVRT), and tissue Doppler tricuspid annular late velocity (A't) were reduced significantly in patients with RRVFP than in those without RRVFP (At 19.6 ± 2.7 vs. 39.1 ± 7.4 cm/s, p < 0.001; DTt 106 ± 13 vs.156 ± 21 ms, p = 0.001; IVRT 59 ± 6.7 vs. 62 ± 7.4 ms, p = 0.01; A't 4.6 ± 1.1 vs. 8.6 ± 1.05, p = 0.001). Et/At ratios were higher in patients with RRVFP than in those without RRVFP (Et/At 2.20 ± 0.2 vs. 1.15 ± 0.37, p < 0.001). Et, tissue Doppler tricuspid annular early velocity (E't), E't/A't ratio, and Et/E't ratio were not significantly different between groups (Et 43.3 ± 5.4 vs. 40.7 ± 9.2 cm/s p = 0.18; E't 8.8 ± 1.4 vs. 9.5 ± 2.3, p = 0.15; E't/A't 1.08 ± 0.24 vs. 1.13 ± 0.30, p = 0.52; Et/E't ratio 5.0 ± 1.1 vs. 4.5 ± 1.5 p = 0.09). Presence of E't/A't > 2, short DTt, RRVFP, unsuccessful p­PCI, and cardiogenic shock on admission were independent predictors of in-hospital mortality (p < 0.05) in multivariable logistic regression analysis. CONCLUSION: Presence of RRVFP is associated with in-hospital mortality in patients presenting with their first IWMI complicated by RVMI.
