“…Guide wire insertion time was decreased by 39% and radiation exposure was reduced by 41.5% (as measured by fluoroscopy pulse counts), without prolonging surgery time, unlike the ordinary navigation systems, where radiation exposure is reduced at the expense of the time spent for bony tracker insertion, registration and calibration (3,14). The Surgix system is different from classical optically tracked navigation systems in that it does not require placement of bone trackers or cage calibration.…”

“…These techniques enable better positioning of the implants and have been shown to improve surgeons' performances as well as the outcome of surgery for fracture fixation (1,2). However, standard computerized navigation systems are time consuming; they need additional operation sites for insertion of the frames of the bone tracker and they need to be set up and calibrated (3). This considerably increases operation time and interrupts the flow of surgery.…”

“…Furthermore, the need to rotate the C-arm fluoroscope in order to visualize the anteroposterior (AP) and lateral plane of the proximal femur may prolong the operation time and endanger sterility. Computer-assisted navigation has been used in trauma surgery to improve the accuracy of guide wire placement for positioning cannulated screws and dynamic hip screws (DHS) while reducing the number of drilling attempts and radiation exposure [10][11][12][13]. Although a significant reduction in fluoroscopy time has been reported, more than two X-ray images were usually necessary to achieve optimal orientation of the AP and lateral projections of the proximal femur for planning the guide wire position [10][11][12][13].…”

BIOMEDICAL PAPEREvaluation of a fluoroscopy-based navigation system enabling a virtual radiation-free preview of X-ray images for placement of cannulated hip screws. A cadaver study Abstract 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 screw placement. The planning process was supported by a tool that enables a virtual radiation-free preview of X-ray images. This is called ''zero-dose C-arm navigation''. For the evaluation of the system, six formalin-fixed cadaveric fullbody specimens (12 femurs) were used. The evaluation demonstrated the feasibility of fluoroscopically navigated guide wire and implant placement. Use of the novel system resulted in a significant reduction in the number of fluoroscopic images and drilling attempts while achieving optimized accuracy by attaining better screw parallelism and enlarged neckwidth coverage. Operation time was significantly longer in the navigation assisted group. The system has yielded promising initial results; however, additional studies using fractured bone models and with extension of the navigation process to track two bone fragments must be performed before integration of this navigation system into the clinical workflow is possible, and these studies should focus on reducing the operation time.

“…This treatment methodology has also been shown to be advantageous for intertrochanteric fractures of the femur, thereby reducing the bleeding and pain and providing earlier rehabilitation for these patients, who are mostly elderly (1)(2)(3)(4)(5)(6)(7) .…”

The authors declare that there was no conflict of interest in conducting this work ABSTRACTThe MINUS system was developed as a minimally invasive procedure that uses a diaphyseal cephalic extramedullary implant for the treatment of transtrochanteral fractures of the femur in elderly patients. The implant consists of a sliding screw coupled to a plate adapted to the minimally invasive technique. The surgical access is approximately three centimeters in length located on the lateral surface of the hip, below the projection of the small trochanter. A perfectly adapted instrument was used for the procedure, which also requires the use of an image intensifier, reducing surgery time and rate of bleeding. The objective of this study is to present a new instrument and implant, developed specifically for treatment with the minimally invasive technique, reducing the length of the conventional surgical access from 10 to three centimetres. This new implant was given the commercial name of MI-NUS System.
