The aim of trajectory navigation is to position a surgical instrument along a planned trajectory. Computer assisted navigation systems show maximal flexibility but are limited by the costs and accuracy of the used optical tracking system and the human errors during free-hand navigation. Robotic devices can reach highest accuracy but are expensive and(More)
Accurate placement of cannulated screws is essential to ensure fixation of medial femoral neck fractures. The conventional technique may require multiple guide wire passes, and relies heavily on fluoroscopy. A computer-assisted planning and navigation system based on 2D fluoroscopy for guide wire placement in the femoral neck has been developed to improve(More)
Abstract In the proximal femur, a high accuracy of implant placement reduces the risk of mechanical failure. We have tested a new computer-assisted planning and navigation system based on two-dimensional fluoroscopy using the so-called zero-dose C-arm navigation approach to optimise implant placement in fracture fixation and hip resurfacing. The aim of this(More)
Pertrochanteric femoral fractures are common and intramedullary nailing is an accepted method for their surgical treatment. Accurate placement of the implant is essential to ensure fixation. The conventional technique can require multiple guide wire passes, and relies heavily on fluoroscopy. A computer-assisted planning and navigation system based on(More)
PURPOSE Dynamic hip screw (DHS) insertion for the fixation of lateral femoral neck fractures is an accepted surgical treatment method. A computer-assisted planning and navigation system based on 2D fluoroscopy has been developed for guidewire insertion in order to perform screw placement. The image acquisition process was supported by a radiation-saving(More)
