A rectangular rod is placed in a flow field flowing parallel to a flat plate. Effect of chord-thickness ratio of rectangular rod on developing vortex shedding downstream to the rod is studied. Then, for each one of the aspect ratios, the distance of the rod from the neighboring flat plate is reduced until the rod sticks to the flat plate. In each case, the effect of the flat plate boundary laye...

BACKGROUND AND PURPOSE Because intramedullary spinal cord metastasis is often a difficult diagnosis to make, our purpose was to perform a systematic review of the MR imaging and relevant baseline clinical features of intramedullary spinal cord metastases in a large series. MATERIALS AND METHODS Consecutive patients with intramedullary spinal cord metastasis with available pretreatment digital...

BACKGROUND AND OBJECTIVE Intramedullary nailing is commonly used for treating femoral shaft fractures, one of the most common long bone fractures in adults. The reamed intramedullary nail is considered the standard implant for femoral fractures. This meta-analysis was performed to verify the superiority of reamed intramedullary nailing over unreamed intramedullary nailing in fractures of the fe...

BACKGROUND Extramedullary cortical button-based fixation for distal biceps tendon ruptures exhibits maximum load to failure in vitro but cannot restore the anatomic footprint and has the potential risk for injury to the posterior interosseous nerve. HYPOTHESIS Double intramedullary cortical button fixation repair provides superior fixation strength to the bone when compared with single extram...

BACKGROUND AND PURPOSE Most intramedullary astrocytomas have been known to exhibit at least some enhancement on MR imaging regardless of cell type or tumor grade. The purpose of this study was to evaluate the incidence of nonenhancing intramedullary astrocytomas through a retrospective study within our institutions and a systematic review of the medical literature. MATERIALS AND METHODS A tot...

Primary intramedullary spinal cord tumors are rare in domestic animals and extremely rare in cats [l, 51. This report concerns a primary intramedullary spinal cord tumor in a cat. An 1 1-year-old spayed female domestic shorthair cat was presented to the University of Minnesota Teaching Hospital in lateral recumbency with tetraparesis. All laboratory parameters (electroencephalogram, cerebrospin...

The intramedullary alignment guides used in total knee replacement disrupt the intramedullary vessels, resulting in greater postoperative blood loss. The use of an autologous bone plug to seal the intramedullary femoral canal has been shown to be effective in reducing postoperative bleeding. The authors present a simple technique to create a bone plug from the anterior chamfer femoral cut to pe...
