INTRODUCTION Although parachute landing injuries are thought to be due in part to a lack of exposure of trainees to realistic descent velocities during parachute landing fall (PLF) training, no research has systematically investigated whether PLF technique is affected by different vertical descent conditions, with standardized and realistic conditions of horizontal drift. This study was designe...

(A) Before the procedure, large residual ventricular septal shunts could be seen between the occluder and the peak of apex (Online Video 1). (B) After the procedure, the shunts decreased significantly (Online Video 2). LV 1⁄4 left ventricle; RV 1⁄4 right ventricle. A 58-year-old man with exertional dyspnea (New York Heart Association class II) was admitted to our hospital. He suffered from acut...

Military static-line parachuting is a highly tactical and hazardous activity, with a well-documented injury risk. Due to the high impact forces and rapid rate of loading when a parachutist lands, injuries most frequently occur to the lower limbs and the trunk/spine, with ankle injuries accounting for between 30 and 60 % of all parachuting injuries. Although military static-line parachuting inju...
