A novel, minimally invasive distraction device was created for digital lengthening, reducing scarring. This simple, easily assembled device offers a unique approach to finger elongation, improving patient outcomes.

Area of Science:

  • Orthopedic surgery
  • Biomedical engineering

Background:

  • Digital lengthening procedures are crucial for reconstructing digits.
  • Existing distraction devices can cause significant scarring due to multiple K-wire transfixations.

Purpose of the Study:

  • To develop and present a novel, simple, and light distraction device for digital lengthening.
  • To minimize scar formation during finger elongation procedures.

Main Methods:

  • The device utilizes readily available materials: K-wire, miniplates, bolts, nuts, and nonabsorbable suture/wire.
  • Assembly is straightforward and can be performed intraoperatively.
  • Distraction is achieved by a single suture/wire pulling the distal bone segment, unlike multi- K-wire devices.

Main Results:

  • The developed device is easily obtainable and assembled.
  • The unique distraction principle minimizes scar formation compared to conventional methods.
  • Clinical application of the device was successfully reported.

Conclusions:

  • This novel distraction device offers a simpler, less invasive alternative for digital lengthening.
  • The technique effectively reduces scarring associated with finger elongation.
  • The device's ease of assembly and use makes it a practical option for surgical settings.
