Skin grafting is a common treatment for finger trauma. Skin grafting can repair damaged skin tissue and promote wound healing. Skin grafting can preserve the original structure and function of fingers and reduce the deformity and dysfunction of fingers. In addition, skin grafting can also reduce the risk of infection and improve the speed of wound healing. In contrast, bone grinding surgery may need to remove a part of bones, which has a greater impact on the structure and function of fingers. Therefore, skin grafting is a better treatment choice for finger trauma.
