title: "Interpotential" mounting in monolateral Hoffmann fixation.
abstract: The authors carried out an experimental study to quantify the stability of monolateral fixation devices of the Hoffmann type. The technical tests indicated that changes were needed in the geometry of the devices; these were achieved by designing a junction piece which enables the transfixion pins and the smooth stabilization rod to remain in the same plane, while leaving the rest of the instrumentation unchanged. The use of this component makes the fixation device more stable and lighter than the classic monolateral devices commonly used. It also prevents the separation and rotation of the fragments that can occur when rods not in the same plane are subjected to compression.
