Navigation in femoral-shaft fractures—From lab tests to clinical routine

Radiographic cortical thickness parameters as predictors of rotational alignment in proximal femur fractures: A cadaveric study

“…In terms of rotational control, length and axis, and in order to reduce revision rates, navigated nailing procedures have been described. [16][17][18] A study by Hawi et al investigated the surgical outcome of 24 patients who received navigated intramedullary nailing versus 48 patients with conventional nailing procedures in a retrospective study. 18 The authors described a significantly increased radiation exposure time, significantly increased time of surgery as well as a longer preoperative time for the navigated group.…”

A novel combination of computer-assisted reduction technique and three dimensional printed patient-specific external fixator for treatment of tibial fractures

“…Currently, long bone shaft fracture reduction mainly relies on the surgeons' experience. Repeated attempts using C-arm X-rays would increase operative time and possibly cause new damage to the fracture sites, and excessive exposure to X-ray would affect the health of surgeons and patients [6]. Although robotic and navigation techniques can help improve reduction accuracy, they have no significant effects on decreasing the rotation accuracy, compared with traditional methods [19].…”

“…Reduction and fixation are two critical issues for fracture treatment [4,5], both of which have not been currently addressed satisfactorily. Problems such as difficult reduction, complicated surgery, stress shielding, experience-dependence of the doctors, and patients' and surgeons' excessive exposure to radiation are still left unsolved [6,7]. Although the navigation system [8] and robot techniques [9] can help improve the reduction accuracy, drawbacks such as high cost and complexity of operation have limited their clinical applications (Fig.…”

Current state of computer-assisted trauma surgery

“…Femur lengths differed postoperatively by 4±4 mm, although in some cases surgeons accepted slight shortening to lower the risk of pseudoarthrosis. Wilharm also reported, that freehand interlocking can lead to relevant anteversion deviation of up to 10° [32].…”

“…The clinical accuracy of femoral nailing navigations tools were studied by Wilharm et al [32]. Forty patients with femoral shaft fractures were treated with navigation Fig.…”
