This paper describes a surgical navigation system for anterior cruciate ligament (ACL) reconstruction using an autostereoscopic image overlay technique. We superimpose a real three-dimensional (3-D) image onto the patient for image-guided therapy. The images are created by employing an animated visualization of integral videography (IV). IV records and reproduces 3-D images using a micro convex lens...
Currently, the mechanical performances of pinless external fixator are primarily evaluated for application to long bone fractures. A new method that detecting the relative displacement changes of the tibial fragments with the pinless external fixator by the three dimensional measurement system was introduced to evaluate the performance of the pinless external fixator. And such testing item was taken...
In this study, a multi-segment foot motion analysis on hallux valgus patients were performed using the 9-segment foot model and then compared with the results from normal subjects. Results showed that there were no significant differences in hindfoot motions between normal subjects and HV patients. However, noted in HV patients were hyper-external rotation in the talocrural joint, an excessive eversion...
