Background: Computer-assisted surgical navigation techniques have shown promise; however, currently popular systems have limitations. This paper presents the characterization and application of a binocular visual navigation technique in diaphyseal fracture reduction.Methods: A binocular visual tracker (MicronTracker) was introduced to reduce diaphyseal fractures. A transformation matrix was used to acquire the reduction parameters. A transverse diaphyseal fracture was used as a control group.Results: Precision tests were performed with the binocular system using a simulation femoral model with a transverse fracture 12 times. All residual deformations were compared and P < 0.01. Conclusions:The binocular visual navigation technique produces good results with advantages of flexibility and high positional accuracy and shows promise. The Micro-nTracker might lead to further application in the remote navigation field.

“…The RCM mechanism that is predominantly used in medical surgery robotic systems was the prototype for the final pelvic reduction frame presented in this study. Our team has been developing a reduction robot for use with long bone fractures, and we have used it in tibial fracture reduction, and the results have been published in research journals [ 25 – 29 ]. The algorithm and mechanism of the present system could also be the basis for the further studies on the pelvic fracture reduction robot.…”

Purpose The optimal closed reduction technique for unstable pelvic fractures remains controversial. The purpose of this study is to verify the effectiveness and report early experiences with the reduction of unstable pelvic fractures using a computer-aided pelvic reduction frame. Methods From January 2015 to August 2016, a total of 10 patients with unilateral unstable pelvic fractures were included in this study. The surgical reduction procedure was based on the protocol of the computer-aided pelvic reduction frame that we proposed in a previous work. The quality of the reductions achieved using this system was evaluated with residual translational and rotational differences between the actual and virtual reduction positions of pelvis. The duration of the operation was recorded for quality control. Results The mean times required to set up the frame, to complete the virtual surgery simulation, and to reduce the unstable pelvic fractures were 10.3, 20.9, and 7.5 min, respectively. The maximum residual translational and rotational displacements were less than 6.5 mm and 3.71 degrees, respectively. Conclusions This computer-aided reduction frame can be a useful tool for the speedy and accurate reduction of unstable pelvic fractures. Further clinical studies should be conducted with larger patient samples to verify its safety and efficacy.

“…These models must be imported into our software to form a coordinate denoted as fCg. This registration is performed using an ICP algorithm [15] between the proximal fragment and proximal contralateral diaphysis. Afterward, a distal contralateral diaphysis model can be taken as the distal fragment reduction reference standard.…”

“…[14] The fracture patterns and path planning for fracture reduction using surgical robotics was discussed. [15] Additionally, we developed an automated robot for diaphyseal fracture reduction. [16] In that case, we propose a novel master-slave teleoperation robot system for diaphyseal fracture reduction.…”

We developed a novel master-slave teleoperation robot system for diaphyseal fracture reduction. This paper details the mechanical design and the control system as a preliminary study. The fracture reduction accuracy and the performance of the control system are experimentally tested. The mean error in the axial and lateral displacements was below 3 mm; the mean side angle and inward turn errors were below 4. As a preliminary study, the feasibility of the novel master-slave teleoperation robot system for diaphyseal fracture reduction is verified. The robot system fulfills the reduction requirements in accuracy and operating performance.
