“…There are few systematic reviews and research on the use of MR technology in orthopaedic surgery, despite claims of its utility in a number of medical operations. However, the MR-assisted technique has increasingly been employed successfully in recent years for surgeries such placing cervical pedicle screws (24), lumbar fracture (25), total elbow arthroplasty (26), revision hip arthroplasty (27), and knee replacement surgery (28). According to the preoperative strategy, TCC in symptomatic TCC patients was safely and precisely removed in the current study using MR navigation technology.…”

ObjectivesWith positive outcomes recorded, the mixed reality (MR) technology has lately become popular in orthopedic surgery. However, there are few studies that specifically address the utility of MR in talocalcaneal coalitions (TCC) resection. Our goal in this retrospective study is to assess certain data while examining the viability of using MR to treat TCC resection.MethodsSix consecutive patients with TCC diagnosed by computed tomography (CT) for which nonoperative therapy had failed and MR system assisted TCC resection were included in this study from March 2021 to December 2021. The feasibility and accuracy of TCC resection were assessed by post-operation radiography. The American Orthopaedic Foot & Ankle Society (AOFAS) hindfoot score and visual analog scale (VAS) score were used to assess the recovery condition and pain level pre- and post-operation.ResultsThe surgeon can accurately resect the TCC according to the preoperatively determined range by superimposing the holographic model with the actual anatomy of the TCC using an MR system. Additionally, no additional x-ray was necessary while operating. Mean follow-up was 10.3 months, with a minimum of 6 months. There is a significant difference between the preoperative AOFAS score of 53.4 ± 3.8 and the 6-month follow-up AOFAS score of 97.3 ± 2.2 (p < 0.05). There is also a significant difference between the preoperative VAS score of 8.1 ± 0.7 and the 6-month follow-up VAS score of 1.7 ± 0.4 (p < 0.05). All individuals had clinical subtalar mobility without stiffness following surgery.ConclusionWhile the TCC resection operation is being performed, the application of MR technology is practicable, effective, and radiation-free, giving surgeons satisfactory support.

“…Glasses can be used to display information that might be beneficiary to the operator, such as a stream of 2D video in holographic space, 3D volumetric visualization of the patient's body, or direct overlay of the patient, which is not possible with standard displays. Systems based on mixed reality have already been used in cardiac interventions and cardiac surgery [17][18][19][20], orthopaedics [21][22][23], vascular surgery [24,25], and surgical oncology [26].…”

Exact biopsy planning and careful execution of needle injection is crucial to ensure successful procedure completion as initially intended while minimizing the risk of complications. This study introduces a solution aimed at helping the operator navigate to precisely position the needle in a previously planned trajectory utilizing a mixed reality headset. A markerless needle tracking method was developed by integrating deep learning and deterministic computer vision techniques. The system is based on superimposing imaging data onto the patient’s body in order to directly perceive the anatomy and determine a path from the selected injection site to the target location. Four types of tests were conducted to assess the system’s performance: measuring the accuracy of needle pose estimation, determining the distance between injection sites and designated targets, evaluating the efficiency of material collection, and comparing procedure time and number of punctures required with and without the system. These tests, involving both phantoms and physician participation in the latter two, demonstrated the accuracy and usability of the proposed solution. The results showcased a significant improvement, with a reduction in number of punctures needed to reach the target location. The test was successfully completed on the first attempt in 70% of cases, as opposed to only 20% without the system. Additionally, there was a 53% reduction in procedure time, validating the effectiveness of the system.
