Comparison of the stresses generated at the pin-bone interface by standard and conical external fixator pins.
The stresses generated at the pin-bone interface by external fixator pins have been compared using finite element analysis. The results show that higher stresses are generated by conical pins compared with standard pins of the same diameter. This raises the possibility that the rate of pin loosening may be higher for conical pins.
