Comparative Study
The fixation strength of scaphoid bone screws: an in vitro investigation using polyurethane foam.
To compare the compression strength and pull-apart resistance of 5 single-piece scaphoid bone compression screws (Acutrak, Asnis, Herbert, Herbert-Whipple, and Little Grafter), with those of 2 dual-component screws (Kompressor and TwinFix). ⋯ When compression and pull-apart resistance are considered, the Kompressor screw has advantages over other methods of scaphoid fixation.

Recent studies have reported rates of methicillin-resistant Staphylococcus aureus (MRSA) hand infections in patients without risk factors ranging from 26% to 73%. The purpose of our study was to review a large series of pediatric hand infections to determine the rate of MRSA and identify potential risk factors. ⋯ Prognostic IV.
