Nail bed trauma reconstruction and artificial nail replacement - a case report

Area of Science:

• Hand surgery
• Reconstructive surgery
• Trauma care

Background:

• Fingertip trauma often involves nail bed injuries, affecting both function and appearance.
• Reconstruction is essential for restoring fingertip integrity and preventing long-term deformities.
• Partial distal phalanx amputation presents unique reconstructive challenges.

Purpose of the Study:

• To describe a case of partial distal phalanx amputation of the index finger.
• To detail a reconstructive technique for complex fingertip injuries involving the nail bed.
• To highlight the role of temporary artificial nail replacement in healing and aesthetic outcomes.

Main Methods:

• A skin-fat flap was used to cover exposed bone, preserving finger length and sensation.
• A full-thickness skin graft addressed a secondary defect on the finger pulp.
• Nail bed edges were adapted and sutured, with a temporary artificial nail used for support.

Main Results:

• The described technique successfully reconstructed the fingertip, preserving length and radial sensation.
• Nail bed suturing and temporary artificial nail replacement prevented scarring and nail deformity.
• The patient's fingertip regenerated effectively with a restored nail shape.

Conclusions:

• This combined approach, including nail bed repair and temporary artificial nail use, is effective for fingertip reconstruction.
• Temporary artificial nails are vital for protecting the regenerating nail bed and ensuring proper nail shape.
• Optimal fingertip restoration requires careful adaptation of nail bed edges and appropriate support during healing.
