From observations of nail bed injuries, the regeneration of the nail bed seemed evident. The nail bed regenerated well in the presence of the nail matrix and poorly in its absence, suggesting that the nail bed regenerated from the nail matrix. Full-thickness skin graft or flap coverage of nail bed defects resulted in the good nail bed regeneration. The nail bed grew back, pushing the graft or the flap distally. The regenerated nail beds were about 70 percent of normal size in guillotine-type amputations and about 90 percent in the presence of an intact distal phalanx. The difference between full- and split-thickness skin grafts seemed to be adherence to the phalangeal bone, the former giving way to the advancing nail bed and the latter staying in the way. In addition, the destination of the moving nail bed cells was discussed.
通过对甲床损伤的观察，甲床的再生似乎很明显。在有甲母质的情况下，甲床再生良好，而在没有甲母质的情况下则再生不良，这表明甲床是由甲母质再生而来的。全厚皮片或皮瓣覆盖甲床缺损可实现良好的甲床再生。甲床重新生长，将移植皮片或皮瓣向远端推移。在断指型截肢中，再生的甲床约为正常大小的70%，而在远端指骨完整的情况下约为90%。全厚皮片和中厚皮片之间的差异似乎在于与指骨的粘连情况，前者会让位于向前推进的甲床，而后者则会阻碍甲床生长。此外，还讨论了移动的甲床细胞的去向。
