With 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.
Six 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.
The 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 ( < 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 ( < 0.05). All individuals had clinical subtalar mobility without stiffness following surgery.
While the TCC resection operation is being performed, the application of MR technology is practicable, effective, and radiation-free, giving surgeons satisfactory support.
随着取得了积极的成果记录，混合现实（MR）技术最近在骨科手术中变得流行起来。然而，很少有研究专门探讨MR在距下关节联合（TCC）切除术中的效用。我们这项回顾性研究的目的是在检查使用MR治疗TCC切除术的可行性时评估某些数据。
2021年3月至2021年12月，本研究纳入了6例经计算机断层扫描（CT）诊断为TCC且非手术治疗失败并接受MR系统辅助TCC切除术的连续患者。通过术后X线片评估TCC切除术的可行性和准确性。采用美国矫形足踝协会（AOFAS）后足评分和视觉模拟量表（VAS）评分评估手术前后的恢复情况和疼痛程度。
术者可以通过使用MR系统将全息模型与TCC的实际解剖结构叠加，根据术前确定的范围准确切除TCC。此外，手术过程中无需额外的X线检查。平均随访时间为10.3个月，最短为6个月。术前AOFAS评分为53.4±3.8，6个月随访时AOFAS评分为97.3±2.2，两者之间存在显著差异（<0.05）。术前VAS评分为8.1±0.7，6个月随访时VAS评分为1.7±0.4，两者之间也存在显著差异（<0.05）。所有患者术后临床距下关节活动度良好，无僵硬。
在进行TCC切除术时，MR技术的应用切实可行、有效且无辐射，为术者提供了满意支持。
