external fixator
Orthopedic device with pins or wires inserted into bone and connected to external frames for fracture stabilization.
Full Definition
An external fixator is an orthopedic device used to stabilize fractures through pins, wires, or screws inserted into bone segments and connected to external rods or frames. This system provides stability while maintaining access to soft tissues for wound care or additional procedures. External fixators are commonly used in open fractures, severe comminuted fractures, infected nonunions, or as temporary stabilization in polytrauma patients. The device allows for adjustments in length, angulation, and compression, and can facilitate gradual correction of deformities through distraction osteogenesis.
Usage
Usage note: Commonly abbreviated as 'ex-fix' in informal clinical communication.
