Since the establishment of our finger amputation center, many finger amputation surgeries have been performed, but I have found that many patients, their families, colleagues, etc., do not have enough understanding of the "finger amputation replantation" technique
Today, I will share with you some knowledge about the "finger replantation" technology.
As the name suggests, it is the replanting of a finger that has been amputated from the human body. Why is this surgery not routinely performed in many hospitals? Because it requires the realignment of the severed phalanges, blood vessels, nerves, and tendons, especially to re-establish blood circulation to the severed finger to survive. Not only does this require a long operating time, but it also requires delicate manipulation under a microscope, requiring a lot of energy, eyesight, and microsurgical techniques. Therefore, it is difficult to carry out routine work in many hospitals.
What is the survival rate of "finger replantation"?
The survival rate of finger replantation is related to a variety of factors such as the time of injury, the damage of the finger, the surgical technique, and the individual's own situation.
Generally speaking, the shorter the finger amputation time, the better the preservation conditions, the higher the survival probability, the higher the survival probability of direct finger amputation is higher than that of crushing or avulsion injury, and the mature surgical technology of the finger amputation and replantation center has an experienced medical team, exquisite surgical technology and perfect perioperative management significantly improve the survival probability. In addition, whether the patient has co-infection, whether there is a history of long-term smoking, underlying diseases such as diabetes, and low mood and lack of cooperation with active treatment (some patients with amputated fingers are caused by self-harm) will also affect the survival rate of the patient's finger.
How long does it take to observe a replanted finger to ensure complete survival?
Observation is usually required for at least 5-7 days, and some may be extended to 14 days or more. During this period, it is necessary to strictly abide by the doctor's instructions, indwelling catheterization, absolute bed rest and rest, continuous elevation of the affected limb and exposure to baking lamps, avoid smoking, alcohol, light diet, and rest with peace of mind to avoid depression or excitement. If you have a finger crisis, you need to actively cooperate with the doctor to ensure that the finger survives as much as possible. If the finger unfortunately does not survive, do not be frustrated and discouraged, and remedies such as transposition flap surgery or toenail flap reconstructive thumb surgery can also be used.
Why does the replanted surviving finger feel different from the original?
Almost all patients can feel that the fingers that survive after reimplantation are not the same as before. Although the vascular nerve tendons have been reconstructed, the anastomosed tendons and nerves do have different functions from the original, and they are prone to a series of symptoms such as tendon adhesions, local skin numbness, and hypoesthesia. Can these functions be improved? Symptoms can be partially improved through medication and a series of rehabilitation exercises, but it is almost impossible to completely return to the original functional state.
So if the whole palm of the hand or the whole ball of the foot is broken, can it be revived?
In a more mature replantation center, as long as the preservation conditions, wound conditions and replantation time window allow, it is still entirely possible to successfully replant the entire palm or the entire solar of the foot, or even the entire forearm or the entire foot to survive. However, as with the replanted fingers, the function of the entire palm or forearm and the entire foot still have a significant impact. However, given the limitations of current prosthetic techniques, especially forearm prostheses, the significance of this procedure is significant.
The above is some small knowledge about "finger replantation", I hope that patients can gain something through this article.
