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. Use of the novel system enables a minimally invasive approach to the hip and results in enhanced accuracy of implant placement compared with conventional techniques. Its precision is comparable to navigation systems currently in the market. The new system reduces irradiation but requires more operation time in comparison with established navigation systems. We believe zero-dose C-arm navigation can effectively be used to support surgeons in modern orthopaedic and trauma surgery departments, and can sufficiently serve the demands of both sections, especially at a time focusing on saving costs.
