Feasibility of model-based Roentgen Stereophotogrammetric Analysis to evaluate early migration of the trapeziometacarpal joint prosthesis
BACKGROUND The purpose of this study was to determine the feasibility of Roentgen Stereophotogrammetric Analysis (RSA) in total joint arthroplasty of the trapeziometacarpal (TMC) joint of the thumb. METHODS In five cadaveric hands the TMC-joint was replaced by the Surface Replacement Trapeziometacarpal prosthesis (SR™ TMC prosthesis; Avanta, San Diego, CA) and tantalum beads of 0.8 mm were im...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
Accurate detection of stent-graft migration in a pulsatile aortic model using Roentgen stereophotogrammetric analysis.
PURPOSE To evaluate the feasibility and accuracy of Roentgen stereophotogrammetric analysis (RSA) versus computed tomography (CT) for detecting stent-graft migration in an in vitro pulsatile circulation model and to study the feasibility of a nitinol endovascular clip (NEC) as an aortic wall reference marker for RSA. METHODS An aortic model with stent-graft was constructed and connected to an...
متن کاملTrapeziometacarpal joint replacement with the Arpe prosthesis.
The purpose of the study was to assess the subjective outcome and five-year survival of non-cemented total joint replacement of the trapeziometacarpal joint with the Arpe prothesis. Forty-nine hands were operated on. Outcome scores were obtained with a mean follow-up of 6 years (range: 3-11 years) for 35 prostheses. Mean disability of the arm, shoulder and hand (DASH) score was 8, mean visual a...
متن کاملEstimation of the migration of tibial components in total knee arthroplasty. A roentgen stereophotogrammetric analysis.
Accurate quantitative measurements of micromovement immediately after operation would be a reliable indicator of the stability of an individual component. We have therefore developed a system for measuring micromovement of the tibial component using three non-contact displacement transducers attached to the tibial cortex during total knee arthroplasty (TKA). Using this system we measured the in...
