Computer assisted spine surgery.
When inserting screws into a vertebral pedicle, the surgeon usually exposes the back part of the vertebra and uses his or her anatomic knowledge to align the drill in the proper direction. A slight error in direction may result in an important error in the position of the tip of the screw. This is done with no direct visibility of crucial structures (spinal cord, pleura, vessels). Statistical a...
متن کامل6 Computer-assisted Minimally Invasive Spine Surgery State of the Art 6.2 Computer-assisted Orthopaedic Surgery
With the advent of precise preand intraoperative imaging means, the development of sophisticated image data visualization, and the accessibility of submillimetric, real-time tracking of objects in space, surgical navigation systems have been created that aim at enhanced surgical accuracy and ultimately improved clinical outcome [3, 6, 9, 13, 17, 20]. Numerous studies have shown the superiority ...
متن کاملComputer-Assisted School-Based Asthma Management: A Pilot Study
BACKGROUND The high prevalence of asthma among children continues to be a major public health issue. In particular, low-income African-American and Hispanic children often receive asthma care in the emergency department and lack access to continuity of care. OBJECTIVE The aim of the current study was to test the feasibility of implementing a computerized program for empowering low-income chil...
متن کاملThings you need to know about the Intra-Operative Imaging and Navigation in today’s Computer-Assisted Spine Surgery
A group of physical limitations to these systems exist. The O-arm images are planar and orthogonal and their views are made through digital volumetric construction affecting their spacial accuracy, though, an accuracy of a pexil representation of 1 mm is now available and acceptable [2]. The neuronavigator camera is a static one so far, and the precision of its optical tracking system depends o...
متن کاملEvaluation of a Novel Method of Real time Computer Assisted Spine Surgery
In this paper the effectiveness of a novel method of computer assisted pedicle screw insertion was studied using testing of hypothesis procedure with a sample size of 48. Pattern recognition based on geometric features of markers on the drill has been performed on real time optical video obtained from orthogonally placed CCD cameras. The study reveals the exactness of the calculated position of...
