OBJECTIVES To determine the efficacy and optimal application parameters of circumferential compression to reduce external rotation-type pelvic fractures. DESIGN Biomechanical investigation on human cadaveric specimens. SETTING Biomechanics laboratory. INTERVENTION Partially stable and unstable external rotation injuries of the pelvic ring (OTA classification 61-B1 and 61-C1) were created ...

AIMS To examine myocardial deformation and rotation in patients with heart failure, and elucidate the underlying mechanisms that account for normal ejection fraction (EF) in patients with diastolic heart failure (DHF). METHODS AND RESULTS Fifty consecutive patients presenting with congestive heart failure (age: 58 +/- 16 years) underwent simultaneous right heart catheterization and transthora...

BACKGROUND Lumbar spine fusion rates can vary according to the surgical technique. Although many studies on spinal fusion have been conducted and reported, the heterogeneity of the study designs and data handling make it difficult to identify which approach yields the highest fusion rate. This paper reviews studies that compared the lumbosacral fusion rates achieved with different surgical tech...

OBJECTIVES We sought to investigate the clinical prognostic value of longitudinal and circumferential strain (S) and strain rate (SR) in patients after high-risk myocardial infarction (MI). BACKGROUND Left ventricular (LV) contractile performance after MI is an important predictor of long-term outcome. Tissue deformation imaging might more closely reflect myocardial contractility than traditi...

BACKGROUND Accurate assessment of mechanical properties of the proximal aorta is a requisite first step for elucidating the pathophysiology of isolated systolic hypertension. During systole, substantial proximal aortic axial displacement produces longitudinal strain, which we hypothesize causes variable underestimation of ascending aortic circumferential strain compared to values in the longitu...

PURPOSE To assess myocardial strain using cine displacement encoding with stimulated echoes (DENSE) using 1.5T and 3.0T MRI in healthy adults. MATERIALS AND METHODS Healthy adults without any history of cardiovascular disease underwent magnetic resonance imaging (MRI) at 1.5T and 3.0T within 2 days. The MRI protocol included balanced steady-state free-precession (b-SSFP), 2D cine-echo planar ...

A 58-year-old man presented with a fully circumferential, granular-type, laterally spreading tumor in the rectosigmoid (●" Fig.1a, ●" Fig.1b), which was diagnosed as an intramucosal cancer using magnifying endoscopy. En bloc resection was accomplished by endoscopic submucosal dissection (ESD) using the pocketcreation method [1]. Three submucosal pockets were created, leaving submucosal tissue b...
