Hallux amputations in patients with neuropathy frequently lead to new digital ulcerations and further amputations. Lesser digit amputations show a significantly lower risk of these complications, suggesting a need for revised surgical approaches.

Area of Science:

  • Podiatric surgery
  • Diabetic foot complications
  • Neuropathy research

Background:

  • Digital amputations are common in patients with neuropathy.
  • Hallux amputations have been associated with high rates of post-operative complications.

Purpose of the Study:

  • To compare the incidence of new ulcerations and subsequent amputations after hallux versus lesser digit amputations in patients with neuropathy.
  • To identify potential biomechanical factors contributing to post-amputation ulcerations.

Main Methods:

  • Retrospective analysis of 26 patients undergoing 27 digital amputations.
  • Review of patient records for development of new ulcerations and need for further amputations.
  • Categorization of amputations into hallux and lesser digit procedures.

Main Results:

  • 65% of feet with hallux amputations developed new ulcerations, with 53% occurring distally.
  • 53% of patients undergoing hallux amputation required secondary amputations due to ulcerations.
  • Only 10% of feet with lesser digit amputations developed new ulcerations.

Conclusions:

  • Hallux amputations in neuropathic patients carry a high risk of ulceration and re-amputation.
  • Lesser digit amputations appear to be a safer alternative with lower complication rates.
  • Further research into biomechanics and preventative therapies is warranted to reduce complications.
