Popis: Summary: Closed reduction and intramedullary nailing under x-ray fluoroscopy is the current treatment of choice for femoral shaft fractures. However, many images are required to successfully perform the procedure, especially for distal locking of the nail, resulting in cumulative radiation exposure to the surgeon. Recently, computer-based technologies have been developed for surgical navigation, enabling the surgeon to accurately track in real-time the instruments, implants, and patient anatomy during a procedure. This article reviews the principles and potential benefits of computer-aided image-guided surgery for femoral shaft fracture, its indications, and its pitfalls. The existing systems, commercially available and prototypes, and the early clinical experience using this technique are also briefly discussed. Key Words: Computer-assisted orthopaedic surgery—Image-guided surgery—Femur fracture—Intramedullary nailing. Femoral shaft fractures are best treated with interlocked intramedullary nailing, providing stable fixation to maintain longitudinal and rotational alignment to allow early active range of motion. 2 The introduction of image intensifiers in the operating room has enabled the surgeon to perform both the reduction and stabilization without opening the fracture site, reducing further damage to the traumatized area and maximizing its biologic potential for healing. Closed antegrade nailing is a minimal exposure surgery and is currently the treatment of choice for femoral shaft fractures. 26 However, a great number of fluoroscopic images are required in each step of the procedure to achieve successful anatomic reduction and stable fixation, resulting in cumulative radiation exposure to the surgeon, the surgical team, and the patient. 14 Limitations from this technique arise because
