A new mini-navigator offers accurate tracking for orthopedic surgery, showing high precision in deformity correction. This cost-effective navigation device is comparable to conventional systems.

Area of Science:

  • Orthopedic Surgery
  • Medical Device Technology
  • Surgical Navigation

Background:

  • Conventional electromagnetic navigation systems are used in orthopedic surgery.
  • Tracking bony fragments is crucial for accurate deformity correction.

Purpose of the Study:

  • To introduce a novel navigation device for deformity correction surgery.
  • To assess the accuracy of this new device against a standard electromagnetic navigation system.

Main Methods:

  • The new system utilizes three sensors and PC-based software.
  • Two sensors attach to bone fragments via Schanz screws; one is mounted distally.
  • Accuracy was tested on 118 planned deformities and 300 complex 3D deformities.

Main Results:

  • The mini-navigator demonstrated mean absolute differences of 1.8° (coronal), 1.1° (sagittal), and 0.8° (transverse).
  • Accuracy was significantly influenced by deformity magnitude (P < 0.0001), with higher precision for smaller deformities.
  • The device showed high accuracy in tracking synthetic bony fragments.

Conclusions:

  • The developed navigation technology is accurate and potentially more cost-effective than existing devices.
  • This mini-navigator presents a promising advancement for orthopedic deformity correction surgery.
