Area of Science:

  • Orthopedic Surgery
  • Neurosurgery
  • Microsurgery

Background:

  • Neurorrhaphy outcomes depend on precise surgical technique for tension-free coaptation.
  • Commercially available nerve approximators are effective but costly, limiting their widespread use.
  • An accessible, cost-effective alternative is needed to improve peripheral nerve repair.

Purpose of the Study:

  • To describe a simple, inexpensive, and readily available nerve approximator for peripheral neurorrhaphy.
  • To demonstrate its utility in achieving optimal tension and fascicle coaptation.
  • To highlight its potential application in surgical training.

Main Methods:

  • Utilizing a universal mini external fixator system to construct a novel nerve approximator.
  • Employing the device during peripheral neurorrhaphy procedures.
  • Assessing its ease of use, cost-effectiveness, and impact on coaptation and tension.

Main Results:

  • The described nerve approximator is inexpensive, user-friendly, and atraumatic.
  • It effectively aids in achieving optimal tension and maintaining fascicle coaptation during neurorrhaphy.
  • The device is readily available in orthopedic and hand surgery settings.

Conclusions:

  • This novel nerve approximator offers a practical and economical solution for enhancing peripheral neurorrhaphy.
  • Its clinical application can improve surgical outcomes in nerve repair.
  • The device is also suitable for simulated tendon and nerve repair in laboratory training.
