2020 Proceedings of the 3rd International Conference on Trauma Surgery Technology in Giessen
The 3
rd event of the Giessen International Conference on Trauma Surgery Technology on
October, the 17th 2020 was hosted on Zoom in accordance with the worldwide corona
situation. Dr Mieczakowski, Dr Yu, and Wolfram drafted in 2018 from Jan’s apartment in Bremen the
manuscript which was submitted to and approved for funding by the Deutsche
Forschungsgemeinschaft (DFG). At that time, we had no idea what substantial changes the
conferencing concept would require. This is why we would like to thank again Michele. She first
planned this year’s event after the 2019 date and then in the spring of 2020 had to replan for the
new situation
Bionic forceps for the handling of sensitive tissue
Anatomical forceps are used for the handling of sensitive structures in medicine. Structures which are manipulated with these forceps can get damaged or slip out of the grip of the forceps. This paper presents a forceps using the bionic Fin-Ray-Effect inspired by fish-fins in order to handle vulnerable structures in particular. During the process of development, functional models of this forceps were designed, 3D-printed and evaluated
Ceramics in total disc replacements: A scoping review
Background: Ceramics are used in Total Disc Replacements (1) in articulating surfaces for their wear resistance and biocompatibility and (2) on endplates to promote osseointegration. They furthermore exhibit MRI and CT compatibility. These properties address main challenges associated with non-ceramic Total Disc Replacements i.e. wear, migration and postoperative imaging. While brittleness of ceramics caused fear of fracture in the past, improvements of ceramic materials were made and considerable clinical experience with ceramic Total Disc Replacements was gained. This review aims to assess the evidence on the use of ceramics in Total Disc Replacements and compare safety and effectiveness of ceramic Total Disc Replacements to spinal fusion and Total Disc Replacements in general. Methods: We conducted a scoping review on the use of ceramics in Total Disc Replacements using Scopus, Web of Science and PubMed. The review includes 36 clinical, ex vivo and nonhuman in vivo, tribological and mechanical studies and case reports. Findings: Ceramics are used in cervical Total Disc Replacements, with safety and efficacy confirmed in clinical studies, with up to 10 and 3.3 years follow-up, for articulation and osseointegration applications, respectively. Clinical evidence shows that ceramic Total Disc Replacements (alike non-ceramic ones) restore segmental motion and result in non-inferior and possibly superior outcomes to spinal fusion. In vivo studies show osseointegration comparable to non-ceramic devices. Tribological studies suggest appropriate wear properties. Interpretation: We found no indications of systematic problems with the use of ceramics in Total Disc Replacements. Ceramics are suitable materials for Total Disc Replacements.ISSN:0268-0033ISSN:1879-127
