Abstract: This article describes the design and construction of an electronic
device to assist orthopedic surgeons in the intramedullary nailing of long
bones. The objective of the system is to reduce the cumulative radiation to
which surgeons are exposed while performing the operation, as well as reduce
the time required to complete the task. The system uses the magnetic flux of
permanent magnets and electronic sensors to determine, without the need for a
fluoroscope, the position of the distal hole in the rod. Tests show the system
is feasible.
