Follicular Unit Grafting in Chronic Nonhealing Leg Ulcers: A Clinical Study

Area of Science:

• Dermatology
• Wound Healing
• Regenerative Medicine

Background:

• Epithelial restoration relies on cell migration from wound edges or hair follicles.
• Chronic leg ulcers present a significant challenge in wound management.
• Current treatments for nonhealing ulcers have limitations.

Purpose of the Study:

• To assess the feasibility of using scalp follicular unit grafts in chronic leg ulcer beds.
• To evaluate the healing capacity of these grafts in promoting ulcer closure.
• To determine the potential of this method as a therapeutic alternative.

Main Methods:

• Fifteen patients with chronic nonhealing leg ulcers (duration > 6 weeks) were enrolled.
• Scalp follicular unit grafts were harvested and implanted at a density of 5 grafts/cm².
• Ulcer area and volume changes were measured over 18 weeks post-intervention.

Main Results:

• A mean reduction of 48.8% in ulcer area and 71.98% in ulcer volume was observed.
• The treatment demonstrated statistically significant improvements in both area and volume.
• No adverse events were reported, indicating a safe procedure.

Conclusions:

• Follicular unit grafting is a feasible and safe method for treating chronic leg ulcers.
• This technique shows promise as a novel therapeutic strategy for nonhealing wounds.
• Further research can explore optimizing graft density and patient selection.
