Nail bed refers to the skin covered by human nails or toenails. If it is slightly damaged, it will not affect the normal growth of nails. You can take cystine and calcium to promote the repair of nail bed, eat more foods rich in calcium and protein, such as eggs, milk, fish and shrimp, and pay attention to daily maintenance to keep it dry and hygienic. Don't let the nail bed contact with irritating things and get bumped, so as not to cause secondary injury, otherwise it will lead to abnormal nail growth.
It is a common problem that the nail bed is cut off by a knife in surgical emergencies. After the nail and nail bed are damaged, the function and appearance of fingers are greatly affected. The traditional method of dressing the stump wound will lead to the shortening of the finger and the deformity of the hook nail, and the fingertip plays an important role in the hand function because of its special structure. It is suggested that finger pulp fascial flap combined with nail bed transplantation should be implemented to create conditions for the normal growth of nail bed and nails.
