Workshops

Workshop: I
Application: Image Guided Surgery System - Stryker Navigation
Developer: Stryker Leibinger
Stryker LEIBINGER will be featuring the Stryker Navigation System for Image Guided Surgery. The System boasts wireless software control, automatic instrument identification, self-diagnostic check, and flexible set-up. In addition, the system runs on Microsoft¨ Windows¨ and can be used with a standard laptop for remote planning and navigation.

Workshop: II
Application: Image Guided Surgery using Fluoroscopy for TKA/THA/Trauma
Developer: Smith & Nephew, Inc.
Recent advances in Image Guided Surgery (IGS) have highlighted a number of advantages over traditional orthopaedic surgery. Multiplanar viewing, using standard fluoroscopy, combines patient images with visualization of implants and instruments to allow reduced radiation exposure. New software and instrumentation has been designed for TKA, THA and Trauma applications that may allow less invasive surgery to be performed with more accurate implant placement. Current techniques in Trauma, Total Knee and Hip replacement using this IGS technology are presented.

Demonstrations will be performed by: Dr. David Kahler - Trauma, Dr. Stephen Murphy - TKA, Dr. Dirk Vandevelde - THA

Workshop: IIIa
Application: HipNav
Developer: CASurgica, Inc.
HipNav is the surgical navigation system assisting in planning and placement of implant components in total hip replacement. HipNav uses patient's CT-scan image for planning. After the implants are selected, joint kinematics are simulated to test and maximize the safe range of motion by minimizing both prosthetic and bone impingement. Leg-length and offset changes are also displayed. Intra-operatively, HipNav provides real-time navigational feedback to the surgeon based upon the location of bones and surgical instruments. A simple interface is used to guide the surgeon.

Workshop: IIIb
Application: KneeNav
Developer: Institute for Computer Assisted Orthopaedic Surgery
KneeNav is a CT based surgical navigation system for total knee replacement (TKR) is designed to provide measurements of all critical steps, including soft tissue laxities, cutting jig alignment, and final cuts. Planning can be performed either pre- or intra-operatively. The navigation system is designed to work with any TKR cutting guides. Workshop demonstration will focus on the use of the system to measure conventional surgical practice in TKR.

Workshop: IV
Application: CT-free Navigation with the Orthopilot System in TKA and THA
Developer: AESCULAP AG & Co. KG
During the workshops the operative technique with the Orthopilot will be presented in detail, followed by a short presentation about the clinical results in TKR and THR.

Demonstrations will be performed by the following doctors; Thursday - Dr. Jean-Yves Jenny and Dr. David Stulberg; Friday - Dr. Ulrich Clemens; Saturday - Dr. Jean-Yves Jenny, and Dr. Ulrich Clemens

Workshop: V
Application: Integrated Fluoroscopic Image Guided Surgery System
Developer: GE OEC Medical Systems
The FluoroTrak 9800 Plus integrates c-arm fluorscopy, with electromagnetic surgical navigation for orthopaedic applications. System features include: 1k x 1k image resolution, electromagnetic tracking technology, small unobtrusive instruments, and a low profile calibration fixture. The use of fluoro-based surgical navigation for pedicle screw insertion will be demonstrated in the workshop.

Workshop: VI
Application: CT-Less TKR Application with the Navitrack-System
Developer: Sulzer Orthopedics Ltd. (Baar, Switzerland)
During the workshop Dr. Mattes/Dr. Nizard will give a theoretical introduction to the CT-less application for TKR with the Navitrack software and the corresponding surgical technique. The essential steps for CT-less Navigation like the kinematic analysis of the leg for definition of the femoral head, digitalization of anatomical landmarks and ad-hoc creation of a basic virtual bone model will be presented in detail. The use of the gathered information for the surgical procedure will be demonstrated in the workshop. Furthermore first clinical results will be presented.

Demonstrations will be performed by: Dr. Thomas Mattes and Dr. Rémy Nizard

Workshop: VII
Application: GALILEO: More Accurate Bone Resections in TKR
Developer: PI Precision Implants AG
The GALILEO surgery and navigation system includes the CAS positioning device (minirobot) which enables the surgeon to perform the bone resections in TKR more accurate. The CAS gives total control over the implant position by accurate and repeatable placement of the cutting block. A better primary implant stability is achieved by these high precision resections. Also a higher implant lifetime is expected because of the exact restoration of the mechanical axis.

Workshop: VIII
Application: BrainLAB: Image Guided Surgery for TKR and THR
Developer: BrainLAB Inc.
BrainLAB's will present its proprietary 3D anatomic model morphing for CT-free techniques. In this workshop we will also discuss indications for CT-free and CT-based techniques in total knee replacement and total hip replacement. Live navigation will be performed using both techniques in 3D digital templating, navigated resections, and navigated implant positioning.
