Acellular dermal matrix reconstruction of a nail bed avulsion in a 13-year-old child

Abstract

Nail bed avulsion injuries often require reconstruction, particularly in cases where the avulsed fragment is lost. We describe a simple way to reconstruct a large nail bed defect, with no donor site. A 13-year-old boy with a hypoplastic left heart and autism accidentally sustained a left little distal phalanx injury with an avulsion of 60% of the nail bed, exposing the distal phalanx. This boy had a history of poor compliance, qualifying the need to find a technique that would minimise operative time and dressing changes. As such, it was elected to use an acellular dermal matrix (ADM) (Matriderm) as a one-step reconstruction. Signs of vascularisation of the ADM were noted at 2 weeks, and 3-month follow-up demonstrated integration, with normal nail growth. We found that Matriderm was able to support the regeneration of a full thickness wound in a simple one-step procedure.
