title: Treatment of nail bed avulsions with split-thickness nail bed grafts.
abstract: Experimental studies with squirrel monkeys indicated the feasibility of split-thickness grafting of segments of the nail bed. Thin grafts, when taken from the nail bed, achieved excellent take over of the avulsed areas. Thirty-one patients with avulsion of segments of the nail bed were treated with split-thickness nail bed grafts. The injured nail bed had sufficient residual nail bed to serve as a donor site in 24 patients. The remaining seven patients required split-thickness grafts from the lateral one third of the great toe. Of the 31 treated nail beds, there was a total of five deformities in which there was either nonadherence of the nail or irregularity of the nail surface. Twenty-six had nails with no deformity. No deformities occurred in the graft donor area. The split-thickness nail bed graft offers the advantage of frequent availability of tissue on the same injured digit and the absence of donor site deformity, whether on the same injured digit or a donor great toe.
