It is usually not normal for the finger to be still swollen and painful more than 20 days after the implant surgery for the missing first joint of the middle finger. It may be caused by infection, impaired blood circulation, etc.
Under normal circumstances, about two weeks after the finger implant surgery, the transplanted skin can grow on the finger, during this period to keep the wound clean and dry, to avoid infection and skin necrosis. The newly transplanted skin is basically senseless and will partially recover in about six months through functional exercises.
1. Infection: If there is infection in the wound, swelling and pain in the affected area will often occur.
2. Postoperative blood circulation disorders: Postoperative blood circulation disorders can occur due to vasospasm caused by pain, emotional fluctuations, smoking, and cold stimulation. When arterial spasm, the skin and nails of the severed finger are pale, the abdomen of the finger collapses, the skin appears blotchy when the limb is elevated, the capillary filling time is prolonged, the skin temperature decreases, and the blood seepage from the end of the finger is reduced or does not bleed by needling.
In addition, when venous spasm, the skin and nails of the injured limb were purple, and the abdomen of the finger was distended. After the occurrence of vasospastic blood circulation disorder, the factors causing vasospasm should be found and eliminated in time.
There may be other reasons why the finger is still swollen and painful more than 20 days after the implant surgery for the first missing middle finger, so it is recommended to consult a doctor in time.
