Summary
Accurate intraoperative angle measurement for surgical correction of deformities is vital. This review evaluates image-based and non-image-based technologies, guiding surgeons toward optimal solutions for improved patient outcomes.
Area of Science:
- Orthopedic Surgery
- Surgical Technology
- Medical Instrumentation
Background:
- Precise angle measurement is critical for correcting orientation-related deformities during surgery.
- Current commercial solutions for intraoperative angular measurement are limited and context-specific.
- A systematic evaluation of available technologies is needed to guide clinical practice.
Conclusions:
- The selection of intraoperative angle measurement technology must consider surgical error tolerance, procedure type, and radiation exposure limits.
- This review offers valuable insights for surgeons and aids in the development of future innovative measurement solutions.
- Optimizing technology choice enhances surgical precision and contributes to better postoperative results in deformity correction.
