Generally, the first joint of the middle finger is missing and the skin defect is relatively small and can grow its own skin without implants.
Because of the good regenerative function of skin tissue, if the first joint of the middle finger is missing, the diameter of the skin damage is definitely less than 3 cm, and can be healed by granulation.
However, the connective tissue in the first joint of the middle finger does not have a strong regenerative capacity, and without skin grafting, the healing of the wound will be affected, and the muscle will not regenerate, but will be replaced by connective tissue, forming an obvious scar. At this time, flap transfer can be used to cover the trauma, try to retain the length of the middle finger.
Patients should go to regular public hospitals in time to find a professional doctor for diagnosis and treatment, and need to regularly disinfect the wound and change the medicine to prevent the infection of the wound, and determine the surgical plan as soon as possible.
