RESUMO
We have investigated five devices suitable for scaphoid fixation (ASIF 2.7 mm and 3.5 mm cannulated screws, Herbert, Herbert-Whipple, and Howmedica Universal Compression Screw). The biomechanical properties tested were compression and resistance to cantilever bending. There was no statistically significant difference in compression between devices. There were significant differences in resistance to cantilever bending, with the Howmedica screw being strongest in both failure mode and in ultimate failure strength.

Leiomyosarcoma of the femoral vein is a rare tumor. Physicians involved in the care of athletic patients must not be cavalier in evaluating overuse injuries and should endeavor to make a specific diagnosis. If atypical findings, such as generalized extremity swelling, are present, the physician must consider systemic illness including malignancy in apparently healthy, physically active individuals.
