A new, noninvasive ankle distraction device enhances arthroscopic surgery by providing adjustable joint access. This device offers flexibility, allowing surgeons to apply distraction as needed during procedures for improved outcomes.

Area of Science:

  • Orthopedic Surgery
  • Minimally Invasive Procedures

Background:

  • Arthroscopic ankle surgery is often effective without joint distraction.
  • However, distraction can improve visualization and surgical execution in specific cases.

Purpose of the Study:

  • To introduce and evaluate a novel, noninvasive, and resterilizable distraction device for arthroscopic ankle surgery.
  • To assess the device's ease of use, reproducibility, and effectiveness in improving surgical access.

Main Methods:

  • Development of a simple, noninvasive, and resterilizable ankle distraction device.
  • Application of the device during arthroscopic ankle surgery in a consecutive series of 25 patients.
  • Measurement of applied distraction force and resulting joint distraction (medial and lateral).

Main Results:

  • The device was found to be cheap, easy to apply, and yielded reproducible results.
  • The average distraction force applied was 115 N.
  • The average joint distraction achieved was 4.5 mm medially and 4.3 mm laterally.

Conclusions:

  • The developed distraction device is an effective and versatile tool for arthroscopic ankle surgery.
  • Its main advantage lies in the ability to apply distraction selectively at any point during the procedure.
  • The device can improve surgical access and execution when needed, offering flexibility to the surgeon.
