TL;DR: In this paper, a desktop computer controlled milling device is used as a three-dimensional printer to mold the shape of small reference areas of the bone surface automatically into the body of the template.
Abstract: Recent developments in computer assisted surgery offer promising solutions for the translation of the high accuracy of the preoperative imaging and planning into precise intraoperative surgery. Broad clinical application is hindered by high costs, additional time during intervention, problems of intraoperative man and machine interaction, and the spatially constrained arrangement of additional equipment within the operating theater. An alternative technique for computerized tomographic image based preoperative three-dimensional planning and precise surgery on bone structures using individual templates has been developed. For the preoperative customization of these mechanical tool guides, a desktop computer controlled milling device is used as a three-dimensional printer to mold the shape of small reference areas of the bone surface automatically into the body of the template. Thus, the planned position and orientation of the tool guide in spatial relation to bone is stored in a structural way and can be reproduced intraoperatively by adjusting the position of the customized contact faces of the template until the location of exact fit to the bone is found. No additional computerized equipment or time is needed during surgery. The feasibility of this approach has been shown in spine, hip, and knee surgery, and it has been applied clinically for pelvic repositioning osteotomies in acetabular dysplasia therapy.

TL;DR: Aspekte der Entwicklung eines integrierten klinischen Demonstrators zur chirurgischen Planung and Fertigung of Individualschablonen fur periacetabulare Umstellungsosteotomien dargestellt werden bei der Planung von Eingriffen in der orthopadischen Chirurgie.
Abstract: Bei der Planung von Eingriffen in der orthopadischen Chirurgie kann der Orthopade auf eine Vielzahl von bildgebenden Verfahren zuruckgreifen, wie z.B. CT, MR, Ultraschall und Rontgenaufnahmen. Die jungsten Entwicklungen im Bereich der computerunterstutzten Chirurgie bieten verschiedene Losungsansatze, um die hohe geometrische Genauigkeit der praoperativen Bildgebung und Planung fur eine ebenso prazise intraoperative Ausfuhrung zu nutzen. Am Helmholtz-Institut wurde dafur das Prinzip der Individualschablonen entwickelt. Hierbei werden individuell angepaste Schablonen auf Basis von CT-Daten praoperativ gefertigt, die intraoperativ eine prazise Werkzeugfuhrung fur die geplanten Knochenbearbeitung darstellen. Die Realisierbarkeit des Konzeptes fur verschiedene chirurgische Anwendungen wurde bereits in Laboruntersuchungen sowie in klinischen Applikationen demonstriert. Im folgenden werden Aspekte der Entwicklung eines integrierten klinischen Demonstrators zur chirurgischen Planung und Fertigung von Individualschablonen fur periacetabulare Umstellungsosteotomien dargestellt.

TL;DR: From analyses about endoscopic and orthopaedic surgical interventions a high contribution of critical static working postures is noticed, particularly the assisting surgeons are additionally stressed by static holding work because of the lack of sufficient support devices and holding systems.
Abstract: Introducing new surgical techniques and technical devices into the conventional working system „operating theatre“ as well as efforts integrating new technologies (CAS) require basic analysis of thereby caused problems. Therefore we investigated in cooperation with our clinical partners the surgical workplace concerning posture and holding work using ergonomic analysing methods. From these analyses about endoscopic and orthopaedic surgical interventions a high contribution of critical static working postures is noticed. Particularly the assisting surgeons are additionally stressed by static holding work because of the lack of sufficient support devices and holding systems.

TL;DR: In this article, the authors disclosed methods and devices relating improved articular models, implant components, and related guide tools and procedures that include one or more features derived from patient-data, for example, images of the patient's joint.
Abstract: Methods and devices are disclosed relating improved articular models, implant components, and related guide tools and procedures. In addition, methods and devices are disclosed relating articular models, implant components, and/or related guide tools and procedures that include one or more features derived from patient-data, for example, images of the patient's joint. The data can be used to create a model for analyzing a patient's joint and to devise and evaluate a course of corrective action. The data also can be used to create patient-adapted implant components and related tools and procedures.

TL;DR: In this article, the authors present a method for orthopedic implant design, manufacture, modeling and implantation, as well as surgical tools and kits used therewith, which relates to methods of implant design and manufacturing.
Abstract: This invention is directed to orthopedic implants and systems. The invention also relates to methods of implant design, manufacture, modeling and implantation as well as to surgical tools and kits used therewith. The implants are designed by analyzing the articular surface to be corrected and creating a device with an anatomic or near anatomic fit; or selecting a pre-designed implant having characteristics that give the implant the best fit to the existing defect.
