Accuracy of a novel accelerometer-based navigation (Naviswiss) for total hip arthroplasty in the supine position

BACKGROUND: This study aimed to determine the accuracy of acetabular cup insertion using a novel accelerometer-based navigation system in total hip arthroplasty (THA). METHODS: A single-surgeon study was conducted in which 62 prospective patients with navigation and 42 retrospective patients without...

description BACKGROUND: This study aimed to determine the accuracy of acetabular cup insertion using a novel accelerometer-based navigation system in total hip arthroplasty (THA). METHODS: A single-surgeon study was conducted in which 62 prospective patients with navigation and 42 retrospective patients without navigation in a supine position were compared. Absolute values for errors of radiographic inclination and anteversion were calculated. Navigation error was also calculated. Factors that affected absolute value of navigation error in cup alignment were determined. RESULTS: In the navigation group, mean absolute errors for radiographic inclination and anteversion were 4.1° and 4.3°, respectively. In the control group, mean absolute errors were 6.6° in inclination (p < 0.01) and 5.9° in anteversion (p = 0.04). Mean absolute values of navigation error were 2.8° in inclination and 2.8°in anteversion. Factors affecting navigation errors were not found. CONCLUSION: This novel accelerometer-based navigation system significantly increased the accuracy of cup placement during THA in the supine position.
