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.

Review Meta Analysis
Meta-analysis of imaging techniques for the diagnosis of complex regional pain syndrome type I.
To compare the effectiveness of imaging techniques in aiding and confirming the diagnosis of complex regional pain syndrome (CRPS) type I. ⋯ Diagnostic I.

Controlled Clinical Trial
Ability of near infrared spectroscopy to measure oxygenation in isolated upper extremity muscle compartments.
Near infrared spectroscopy (NIRS), a noninvasive means for monitoring muscle oxygenation, may be useful in the diagnosis of acute compartment syndrome, a condition characterized by poor tissue perfusion. This study used the decrease in muscle oxygenation caused by exercise to investigate the ability of anatomic placement of NIRS sensor pads over compartments of the forearm to isolate perfusion values of a specific compartment. ⋯ Diagnostic III.

Objective assessment of technical skills in hand surgery has been lacking. This article reports on an Objective Structured Assessment of Technical Skills format of a multiple bench-station evaluation of orthopedic surgery residents' technical skills for 3 common upper extremity surgeries. ⋯ Therapeutic II.

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.
