A knowledge-based computer-aided system for closed diaphyseal fracture reduction

Advancing computer-assisted orthopaedic surgery using a hexapod device for closed diaphyseal fracture reduction

“…Within the range of the working space, translation errors were < 2 mm and angulation errors were < 1.2°. Fractures that heal with an angular deformity > 5°in any anatomical plane, or a translational deformity > 10 mm are regarded as malunions (21). These test results showed that the hydraulic drive parts and reduction construction could provide excellent precision, while occupying less space compared with electric telescopic struts.…”

Computer-aided parachute guiding system for closed reduction of diaphyseal fractures

“…The system calculates the adjustment requirements of struts to reduce deformity (13,14). However, we found no quantitative data in the literature on the system's reduction accuracy and reliability (18). Tang (15) and Seide (16,17) designed different external fixators for fracture reduction on the basis of hexapod kinematics and computer technology.…”

A novel combination of computer-assisted reduction technique and three dimensional printed patient-specific external fixator for treatment of tibial fractures

“…Reduction and fixation are two critical issues for fracture treatment [4,5], both of which have not been currently addressed satisfactorily. Problems such as difficult reduction, complicated surgery, stress shielding, experience-dependence of the doctors, and patients' and surgeons' excessive exposure to radiation are still left unsolved [6,7]. Although the navigation system [8] and robot techniques [9] can help improve the reduction accuracy, drawbacks such as high cost and complexity of operation have limited their clinical applications (Fig.…”
