Provisional K-wire fixation maintains the reduction, provides resistance while using a reamer, prevents toggling of the bones and produces a more uniform surface area for the plate and screw placement.
To maintain reduction of the STT construct, one 0.045” K-wire is inserted from the scaphoid through the trapezoid. A subsequent 0.045” K-wire is placed from the trapezium through the trapezoid. Ensure K-wires are positioned volar enough to remain below intended reamed cavity.
If further reduction is required, a third K-wire can be inserted through the trapezium exiting the proximal pole of the scaphoid.
