Summary

Wound healing is impaired in denervated tissues, affecting all healing phases. Strategies should focus on reinnervation to aid recovery in patients with pressure sores or diabetic foot ulcers.

Area of Science:

  • Neuroscience
  • Wound Healing Research
  • Regenerative Medicine

Background:

  • Pressure sores (sacral, trochanteric) and diabetic foot ulcers develop in tissues lacking normal innervation.
  • Insensitive tissue is prone to ulceration and recurrence.
  • The impact of denervation on wound healing requires clarification.

Purpose of the Study:

  • To determine if wound healing is impaired in denervated tissue.
  • To review scientific literature on wound healing in denervated tissues over the past 35 years.

Main Methods:

  • Systematic literature review of studies published in the last 35 years.
  • Analysis of research on wound healing processes in denervated tissues.

Main Results:

  • All phases of wound healing are demonstrably impaired in denervated tissue.
  • The mechanisms of impaired healing in denervated tissue are distinct from disease-specific factors like diabetes.
  • Innervation plays a critical role in the wound healing cascade.

Conclusions:

  • Denervation significantly impairs wound healing through mechanisms independent of underlying diseases.
  • Future wound healing strategies should aim to restore innervation in at-risk tissues.
  • Reinnervation therapies hold promise for treating chronic wounds in denervated areas.
