Fluoroscopy-based computer-assisted navigation for implant placement and hip resurfacing arthroplasty in the proximal femur: the zero-dose C-arm navigation approach.

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 review is to compare the results of this system with the current literature.

Three-dimensional computer-assisted navigation for the placement of cannulated hip screws. A pilot study.

Purpose: Medial femoral neck fractures are common, and closed reduction and internal fixation by three cannulated screws is an accepted method for the surgical treatment. Computer navigation for screw placement may reduce fluoroscopy time, the number of guidewire passes and optimise screw placement.

Methods: In the context of a sawbone study, a computer-assisted planning and navigation system based on 3D-imaging for guidewire placement in the femoral neck was tested to improve screw placement.

Evaluation of a new computer-assisted surgical planning and navigation system based on two-dimensional fluoroscopy for insertion of a proximal femoral nail: an experimental study.

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.

[Evaluation of a 2D fluoroscopy-based navigation system for insertion of the dynamic hip screw (DHS): an experimental study].

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 procedure called "zero-dose C-arm navigation".

[Evaluation of a 2D fluoroscopy-based navigation system for insertion of femoral neck screws. An experimental study].

Introduction: The aim of this study was the evaluation of a new computer-assisted planning and navigation system based on 2D-fluoroscopy for guidewire insertion in order to perform cannulated screw placement into the femoral neck. The image acquisition process was supported by a radiation-saving procedure called Zero-dose C-arm navigation.

Material And Methods: In the context of a sawbone study, we performed insertion of 3 cannulated screws positioned under navigation control as well as using the conventional technique in 12 sawbones.
