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.
对松鼠猴的实验研究表明了甲床节段性断层皮片移植的可行性。从甲床取下的薄皮片在撕脱区域获得了良好的存活。31例甲床节段撕脱患者接受了断层甲床移植治疗。24例患者受伤的甲床有足够的残余甲床作为供区。其余7例患者需要取自拇趾外侧三分之一的断层皮片。在31个接受治疗的甲床中，共有5个出现畸形，表现为指甲不粘连或指甲表面不规则。26个指甲没有畸形。移植供区未出现畸形。断层甲床移植的优点是，无论是在同一受伤手指上还是在供区拇趾上，同一受伤手指上的组织经常可用，且没有供区畸形。
