Area of Science:

  • Orthopedic surgery
  • Hand surgery
  • Reconstructive surgery

Background:

  • Digital ray amputations, often from work accidents, can significantly impair hand function.
  • Restoring length and function to digits is crucial for activities of daily living and employment.

Purpose of the Study:

  • To evaluate the efficacy of digital ray lengthening using a small external fixator.
  • To assess functional outcomes and patient satisfaction following ray lengthening procedures.

Main Methods:

  • 19 ray lengthening procedures were performed on 14 patients using a small external fixator.
  • The technique involved osteotomy and gradual distraction, with supplementary procedures like iliac-crest grafting and corrective osteotomy as needed.

Main Results:

  • A mean lengthening of 20 mm (range 0-32 mm) was achieved across all procedures.
  • High patient satisfaction was reported, with favorable functional results despite multiple associated injuries.

Conclusions:

  • Small external fixator-assisted digital ray lengthening is an effective method for restoring hand function after amputation.
  • The procedure demonstrates good functional outcomes and high patient satisfaction, aiding return to daily activities and employment.
