A new drill stabilising guide significantly reduced time for navigated drilling in orthopaedic procedures. This tool improved efficiency without compromising drilling accuracy, offering a faster alternative to freehand methods.

Area of Science:

  • Orthopaedic Surgery
  • Medical Device Technology
  • Surgical Navigation

Background:

  • Computer navigation enhances accuracy and reduces radiation in orthopaedic surgery.
  • Navigated drilling is a common application, but can be time-consuming.
  • External guides may reduce drilling time in navigated procedures.

Purpose of the Study:

  • To evaluate if an external stabilising guide reduces time for navigated drilling.
  • To compare the time and accuracy of navigated drilling with and without a stabilising guide.

Main Methods:

  • Foam blocks simulating cancellous bone were used as targets.
  • An Iso-C 3D navigation system was employed for 20 trials per condition.
  • Drilling was performed freehand and with a stabilising guide attached to an operating table.

Main Results:

  • Navigated drilling time was significantly reduced with the stabilising guide (4.5 min vs. 5.8 min, p=0.009).
  • No significant difference in drilling accuracy was observed between the two methods.
  • The stabilising guide was easy to set up and attach.

Conclusions:

  • An external stabilising guide facilitates faster navigated drilling.
  • This method improves efficiency without sacrificing accuracy.
  • The guide offers a practical solution for reducing operative time in navigated orthopaedic procedures.
