Definition
The Steinmann Pin is a metal rod for the internal fixation of fractures commonly used in orthopedic surgery. It is similar to K-Wire but with larger diameters. There is no standardized definition of diameter cut off.
Many wire terms are used interchangeably, from mandrel to guide wire to k-wire to Steinmann Pin to Intramedullary pin to fixation pin. Most of the time, there are very subtle differences between the names, depending on design, diameter, threads, usage and the context of the speaker.
