Summary
Holographic guidance using mixed reality significantly improved the accuracy and precision of corrective osteotomies compared to visual estimation and printed templates. This advanced surgical navigation enhances bone deformity correction outcomes.
Area of Science:
- Orthopedic surgery
- Surgical navigation
- Mixed reality applications
Background:
- Bone deformities like cubitus varus can impair joint function.
- Corrective osteotomy restores anatomical alignment.
- Surgical navigation precision is crucial for osteotomy success.
Purpose of the Study:
- To validate holographic guidance accuracy and precision.
- Comparison against visual estimation and printed templates.
- Laboratory setting evaluation for corrective osteotomy.
Main Methods:
- Closed-wedge osteotomies (15°, 30°) on porcine femora.
- Evaluated techniques: visual estimation, printed templates, holographic guidance (mixed reality).
- Measured osteotomy angles and alignment (AP/lateral) using physical and digital methods.
Main Results:
- Holographic guidance (HW) showed superior accuracy and precision at 15° and 30° compared to visual estimation (EB).
- HW yielded the lowest systematic error at 15°.
- At 30°, HW achieved best AP and lateral alignment, improving lateral alignment by over 5°.
Conclusions:
- Augmented reality (holographic guidance) offers accurate and precise intraoperative navigation.
- Holographic guidance surpasses visual estimation and printed templates in corrective osteotomy.
- Mixed reality systems show promise for enhancing surgical accuracy in bone deformity correction.
