Eighty embalmed cadaver wrists (40 right and 40 left, 55 male and 25 female, aged 36 to 93 years [average age, 72.5 years]) were dissected to assess the anatomy of the pisotriquetral joint and the location of degenerative changes. The patterns of degenerative changes were classified into five types: type 1, central (8.8%); type 2, peripheral (38.8%); type(More)
The purpose of this study was to examine the anatomy and mechanical properties of the dorsal radiocarpal (DRC) and dorsal intercarpal (DIC) ligaments of the wrist and to better understand the functional design of the dorsal ligaments. The DRC ligament was consistently found to originate from the dorsal margin of the distal radius and extended ulnar(More)
We performed a minimally invasive direct coronary artery bypass (MIDCAB) on two patients for third-time revascularization. The first patient was a 66-year-old woman who had patent bilateral internal thoracic artery (ITA) grafts and an occluded radial artery (RA) graft anastomosed to the posterolateral (PL) branch.
