The primary goal in the treatment of the nail bed avulsion injury is complete regrowing of the nail plate without any deformity. There are many procedures for treatment of the nail bed avulsion injury as a split-thickness skin graft, full-thickness nail bed graft, reverse dermal graft or split-thickness nail bed graft. From February, 1984 to June, 1985 at In-Chon Gill Hospital, 13 cases of nail bed avulsion injury were treated with split-thickness nail bed grafts. The intact residual part of the injured nail bed or the toe nail bed was served as a donor site. The results were as followings; 1. The incidence of nail bed avulsion injury of all hand injuries was 9.7%. 2. The main cause of injury was the industrial accident and more prevalent in the left hand. 3. The good result was obtained in the split-thickness nail bed graft for the nail bed avulsion injury, but in nail root portion, the poor result was noticed. 4. The average time for normal nail appearance is six months.
