During the treatment of tibial fracture with interlocking nail, the most uncomfortable procedure for an orthopedic surgeon Is to find the location for distal locking screws. In this study, hands-on practice and implementation of a sound-guided 3D navigation system was discussed for the fixation of distal locking screws in the tibial intramedullary nailing. This system consists of a 3D digitizer arm, 3D coordinate registration / transformation module and sound-guided navigation module. In addition, the proposed sound-guided navigation module was designed with an audio guiding mechanism through which a sound with different tones and intermittence frequencies will be produced for surgical manipulation. In vitro assessment was performed with a donor bone successfully, and a clinical case of a young male with tibial fracture was also carried out at the operation theater with satisfied results. No preoperative computed tomography or intraoperative fluoroscopy was required. ? 2005 IEEE.Computerized tomographyFractureNavigation systemsOrthopedicsPatient treatmentThree dimensionalDistal locking screwsOrthopedic surgeriesSound guidedSurgical equipmentconference paper10.1109/ICMECH.2005.15293352-s2.0-33748892435
