Background:
While limb elevation and other methods for reducing hand edema are commonly used in clinical practice, alternative methods, such as compression and venous perfusion assist system (VPAS), have emerged. This study compared the efficacy of VPAS to limb elevation in decreasing hand edema after surgery for distal radial fracture (DRF) treated by a volar locking plate (VLP).
Methods:
A randomized controlled trial was conducted in 102 patients to compare VPAS and elevation methods for edema reduction following VLP fixation for DRF. Changes in edema were measured using the tape measure method along with other parameters on the next day and at one, three, six, and 12 weeks postoperatively.
Results:
There were no significant differences in edema reduction or other factors between the VPAS and elevation groups at any measurement point.
Conclusions:
VPAS appears to confer no measurable advantage over management with elevation for edema reduction after VLP fixation of DRF.
Trials Registry:
This study was registered at the University Hospital Medical Information Network Clinical Trials Registry (UMIN000015640).

Freezing Point Depression and Boiling Point Elevation
The boiling point of a liquid is the temperature at which its vapor pressure is equal to ambient atmospheric pressure. Since the vapor pressure of a solution is lowered due to the presence of nonvolatile solutes, it stands to reason that the solution’s boiling point will subsequently be increased. Vapor pressure increases with temperature, and so a solution will require a higher temperature than will pure solvent to achieve any given vapor pressure, including one...

Self-Locking Screw
A square-threaded screw jack carrying a load is considered self-locking if the screw retains its position even after the moment applied to it is removed.
Conjugate Addition (1,4-Addition) vs Direct Addition (1,2-Addition)
Conjugate addition results in a thermodynamically stable product. The reaction retains the stronger C=O bond at the expense of the weaker C=C π bond. The process is slow as the β carbon is less electrophilic than the carbonyl carbon.
Direct addition products are...
