Early Enlargement of Aneurysmal Sac and Separation of EndoBags of Nellix Endovascular Aneurysm Sealing System as Signs of Increased Risk of Later Aneurysm Rupture.

Nellix Endovascular Aneurysm Sealing (EVAS) system is a new concept and technology of abdominal aortic aneurysm (AAA) repair. Elective EVAS using Nellix device was performed for a 83-year-old man with AAA. 2-month post-EVAS CTA surveillance demonstrated mild enlargement of aneurysmal sac and separation of the EndoBags, but without detectable endoleak.

Low-magnitude high-frequency vibration accelerates callus formation, mineralization, and fracture healing in rats.

Fracture healing is a biological regenerative process that follows a well-orchestrated sequence. Most healing is uneventful and enhancement of normal fracture healing is not commonly done, although it is clinically important in the recovery and regain of functions after fracture. This study investigated the osteogenic effect of low-magnitude high-frequency vibration (LMHFV, 35 Hz, 0.

Biomechanical study of an anthropometrically designed hip protector for older chinese women.

Biomechanical properties and compliance are 2 essential properties of hip protectors (HPs) that determine their clinical efficacy. This study describes the development of a HP that was anthropometrically designed according to anthropometric data from 68 older Chinese women and with attention paid to the biomechanical properties of the device. A simulated mechanical fall test using a drop weight and a force plate were set up to test the force attenuation properties of the HP.
