Abstract
PurposeThis study presents a novel surgical navigation tool developed in mixed reality environment for orthopaedic surgery. Joint and skeletal deformities affect all age groups and greatly reduce the range of motion of the joints. These deformities are notoriously difficult to diagnose and to correct through surgery.MethodWe have developed a surgical tool which integrates surgical instrument tracking and augmented reality through a head mounted display. This allows the surgeon to visualise bones with the illusion of possessing “X-ray” vision. The studies presented below aim to assess the accuracy of the surgical navigation tool in tracking a location at the tip of the surgical instrument in holographic space.ResultsResults show that the average accuracy provided by the navigation tool is around 8 mm, and qualitative assessment by the orthopaedic surgeons provided positive feedback in terms of the capabilities for diagnostic use.ConclusionsMore improvements are necessary for the navigation tool to be accurate enough for surgical applications, however, this new tool has the potential to improve diagnostic accuracy and allow for safer and more precise surgeries, as well as provide for better learning conditions for orthopaedic surgeons in training.
Highlights
A large number of patients suffer from different joint and skeletal diseases
This study aims to evaluate the accuracy of this mixed reality tool for clinical use for orthopaedic hip and pelvic diagnostics and surgery
Twenty-eight target positions, at six different orientation planes, were used in each experiment to evaluate the accuracy of the Mixed Reality (MR) navigation tool
Summary
A large number of patients suffer from different joint and skeletal diseases. These can be both congenital and acquired and affect all age groups. Hip dysplasia and epiphysiolysis capitis femoris are examples of such pathological conditions. These conditions cause hip, knee and groin pain, and reduced range of motion of the joint. These can lead to a limping gait, problems with activity of daily life and reduced quality of life. Skeletal and joint conditions are notoriously difficult to diagnose and treat. Diagnosis of orthopaedic conditions are largely dependent on the experience of the clinician and the outcome of the surgery is
