provisional K-wire
Temporary Kirschner wire placed to maintain fracture reduction during definitive fixation procedures.
Full Definition
A provisional K-wire is a temporary fixation device used to hold fracture fragments in proper alignment while definitive hardware is being applied. These thin metal wires provide immediate stability during surgery, preventing loss of reduction as plates, screws, or other implants are positioned. Provisional K-wires are typically removed once permanent fixation is achieved, though some may be left in place if they provide additional stability without interfering with function. The strategic placement of provisional wires is crucial for maintaining optimal fracture alignment throughout the surgical procedure.
Usage
Usage note: Always specify 'provisional' to distinguish from permanent K-wire fixation.
