Steinmann pin

A fine surgical nail passed through the lower end of the FEMUR or the upper end of the TIBIA and held under tension in a steel stirrup so that TRACTION can be applied in the treatment of fractures. (Fritz Steinmann, 1872–1932, Swiss surgeon).

extension exerted on the distal fragment of a fractured bone by means of a nail or pin (Steinmann pin) driven into the fragment. Called also nail extension.
Steinmann pin
intramedullary pin with a choice of ends, either screw, chisel or trocar. Can be plain at one end or have one of the selected points at each end. Pin drills to drill the holes for the pins, and a chuck to grasp the end of the pin and drive or rotate it are available.

A sheet of thermoplastic material (Veterinary Thermoplastic; IMEX) 280-mm long (twice the distance from the Steinmann pin to the distal fixation pin) by 40-mm wide and 2.
All 4 constructs failed by breakage of the acrylic connecting bar at the junction of the bar and the fixation pin closest to the bent Steinmann pin.
The reason for this is not known, but it can be speculated that, because the Steinmann pin and the proximal fixation pin are located very close to each other, a very rigid section is created in the connecting bar, followed by a more flexible segment.
This deviation was attributed to the motion of the fixation pin in contact with the Steinmann pin trocar.
The lack of a significant difference in bending in the safe load was probably because of the relatively large Steinmann pin opposing the majority of the bending forces and minimizing the effect of the other components of the fixator.
To explain the lack of difference in safe load in axial compression in this study, it can be theorized that the Steinmann pin linked to the connecting bar takes some of the load applied to the plastic bone model and minimizes the effect of the connecting bar strength in small displacement.
This suggested that reinforcing the transcortically placed Steinmann pins with acrylic material is adequate for smaller sized ruminants but do not provide rigid fixation for angularly placed tibia in adult cows.
