Twenty-four cases of nonvascularized nail bed grafting to correct nail deformities were reviewed. The highest success rate in improving the appearance of the deformed nail, 86%, was achieved when the split-thickness nail bed graft of sterile matrix was used to correct a nail deformity caused by a sterile matrix injury; the same procedure used to correct a nail deformity caused by a germinal matrix injury had a 0% success rate. Donor site morbidity occurred in 25% of split-thickness nail bed grafts and 100% of full-thickness nail bed grafts. The split-thickness nail bed graft of sterile matrix, if used in properly selected patients, will consistently improve the appearance of the deformed nail.
回顾了24例采用非血管化甲床移植矫正指甲畸形的病例。当使用无菌甲母质的断层甲床移植来矫正由无菌甲母质损伤引起的指甲畸形时，改善畸形指甲外观的成功率最高，为86%；而用同样的方法矫正由生发基质损伤引起的指甲畸形，成功率为0%。断层甲床移植供区并发症发生率为25%，全层甲床移植为100%。如果应用于合适的患者，无菌甲母质的断层甲床移植将持续改善畸形指甲的外观。
