Secondary removal of intramedullary metal debris from a defective Reamer-Irrigator-Aspirator (RIA) reamer head: A case report.

The Reamer-Irrigator-Aspirator (RIA) device represents a safe and efficient method to harvest autologous bone for grafting. However, hardware failure may occur, for example by breakage of the reamer head with metal debris remaining in the intramedullary canal. This case report describes the uncomplicated secondary removal of femoral intramedullary metal debris from a broken RIA reamer head; three weeks after the final surgery of a two-stage Masquelet procedure for the treatment of posttraumatic segmental bone loss at the tibia.

Fracture fixation in polytraumatized patients-From an interdisciplinary early total/appropriate care to the safe definitive surgery concept.

The strategies for the timing of fracture fixation in polytrauma patients have changed with improvements in resuscitation and patient assessment. Specifically, the criteria for damage control have been formulated, and more precise parameters have been found to determine those patients who can safely undergo primary definitive fixation of major fractures. Our current recommendations are supported by objective and data-based criteria and development groups.

Augmented reality-based surgical navigation of pelvic screw placement: an ex-vivo experimental feasibility study.

Background: Minimally invasive surgical treatment of pelvic trauma requires a significant level of surgical training and technical expertise. Novel imaging and navigation technologies have always driven surgical technique, and with head-mounted displays being commercially available nowadays, the assessment of such Augmented Reality (AR) devices in a specific surgical setting is appropriate.

Methods: In this ex-vivo feasibility study, an AR-based surgical navigation system was assessed in a specific clinical scenario with standard pelvic and acetabular screw pathways.

Remote Interactive Surgery Platform (RISP): Proof of Concept for an Augmented-Reality-Based Platform for Surgical Telementoring.

The "Remote Interactive Surgery Platform" (RISP) is an augmented reality (AR)-based platform for surgical telementoring. It builds upon recent advances of mixed reality head-mounted displays (MR-HMD) and associated immersive visualization technologies to assist the surgeon during an operation. It enables an interactive, real-time collaboration with a remote consultant by sharing the operating surgeon's field of view through the Microsoft (MS) HoloLens2 (HL2).
