There is a wide variation in how long it takes for a severed finger to be able to feel after reimplantation. If the severed finger survives, the sensory function usually recovers gradually within 8 to 20 weeks. The recovery of sensory function in reimplantation of severed fingers is related to the degree of injury, the timing of reimplantation, age and the presence of underlying diseases. Skin sensation is completely lost when the nerve is completely severed, and during regeneration, the order of recovery of sensory function varies, with pain, touch, and two-point discrimination in that order. The sensory function of the reimplanted finger was evaluated, and the sensory score of the patient was around 2~6 at 8 weeks, while the score was close to 20 at 20 weeks. Therefore, if standardized treatment is provided, the sensory function of the severed finger will be gradually recovered within 8 to 20 weeks, and there are some individual differences in the degree of recovery. It is recommended to follow the doctor’s instructions to standardize the treatment after finger reimplantation, to carry out rehabilitation exercises at an early stage, and to improve the prognosis by combining methylcobalamin, low molecular heparin and other drugs if necessary.
