Augmented reality guides orthopedic surgery

A group from Johns Hopkins University uses augmented reality visualization to help implantation of surgical nails in patients with femoral fractures. Results from first experience show that accuracy is similar to conventional method but procedure time is reduced by nearly 10% and x-ray acquisitions are reduced by 90%.

The group from Johns Hopkins University used x-ray images acquired with a C-arm to create virtual lines visible with an AR headset for guiding the implantation of surgical nails in patients with femoral fractures. They evaluated this AR method in surgical simulations and found that it decreased both the amount of time and number of x-ray acquisitions required for the procedure, compared with the traditional image-guided technique (JMI, April 2018, Vol. 5:2, 021209).
