Effect of surgical factors on the augmentation of cement-injectable cannulated pedicle screw fixation

Haolin Sun, Chun Liu, Shunlun Chen, Yanjie Bai, Huilin Yang, Chunde Li, Lei Yang

Frontiers of Medicine 2019, Volume 13, Issue 5,   Pages 590-601 doi: 10.1007/s11684-019-0710-z

Abstract: Bone cement-augmented pedicle screw system demonstrates great efficacy in spinal disease treatments.novel injectable and biodegradable calcium phosphate-based nanocomposite (CPN) for the augmentation of pediclescrew fixation was systematically evaluated for its surgical feasibility and biomechanical performanceemployed to evaluate the augmentation effects of CPN on bone tissue and on the cement-injected cannulated pediclepedicle screw loosening scenarios, were studied in comparison with those in PMMA.

New spinal robotic technologies

Bowen Jiang, Tej D. Azad, Ethan Cottrill, Corinna C. Zygourakis, Alex M. Zhu, Neil Crawford, Nicholas Theodore

Frontiers of Medicine 2019, Volume 13, Issue 6,   Pages 723-729 doi: 10.1007/s11684-019-0716-6

Abstract: Robotic systems in surgery have developed rapidly. Installations of the da Vinci Surgical System (Intuitive Surgical, Sunnyvale, CA, USA), widely used in urological and gynecological procedures, have nearly doubled in the United States from 2010 to 2017. Robotics systems in spine surgery have been adopted more slowly; however, users are enthusiastic about their applications in this subspecialty. Spinal surgery often requires fine manipulation of vital structures that must be accessed via limited surgical corridors and can require repetitive tasks over lengthy periods of time — issues for which robotic assistance is well-positioned to complement human ability. To date, the United States Food and Drug Administration (FDA) has approved 7 robotic systems across 4 companies for use in spinal surgery. The available clinical data evaluating their efficacy have generally demonstrated these systems to be accurate and safe. A critical next step in the broader adoption of surgical robotics in spine surgery is the design and implementation of rigorous comparative studies to interrogate the utility of robotic assistance. Here we discuss current applications of robotics in spine surgery, review robotic systems FDA-approved for use in spine surgery, summarize randomized controlled trials involving robotics in spine surgery, and comment on prospects of robotic-assisted spine surgery.
