The finger replantation usually occurs in mechanical workers and athletes, often caused by improper operation of external machinery or improper movement, resulting in the appearance of broken fingers, some patients with broken fingers also have systemic symptoms, and even a little bit may involve internal organs. The surgical characteristics of finger replantation 1, finger replantation by immersion in certain liquids Wrongly immersed in hypotonic, isotonic, hypertonic or certain disinfectant solutions, or improperly preserved, ice cubes melted after ice water immersion, due to the role of cellular semipermeable membrane, hypotonic night makes cells swell with edema, hypertonic solution makes cells dehydrated, certain disinfectant solutions, such as ethanol, benzalkonium bromide, thimerosal, etc. directly damage vascular endothelial cells and Depending on the type, concentration and length of immersion time, the degree of damage varies and has different effects on survival. 2.Replantation of the severed thumb The thumb is the most important in the function of the hand, so it should be considered as a priority when replanting, and we should try our best to repair the thumb early. 3.Replantation of the remaining 4 fingers From the functional point of view, the index and middle fingers are more important. For the severed index and middle fingers that are eligible for replantation, they should be replanted, while the other fingers should not be replanted in general except for special needs of occupation or other factors. 4.re-implantation of the end joint mainly refers to the distal interphalangeal joint to the distal finger break, because the loss of the end joint does not affect the function of the hand, and therefore does not advocate re-implantation, and the simple in situ suture also has a certain survival rate, and the patient’s functional needs of certain special occupations, psychological and cosmetic requirements, can also try to re-implantation, 5.destructive injury of the wrist and palm treatment of the wrist and palm or together with the distal segment of the forearm serious In the case of severe injury or severance of the carpometacarpal region or the distal segment of the forearm, while the distal fingers are still intact, the rotten carpometacarpal region can be removed, and after thorough debridement, the more intact fingers can be fixed to the ulna and radius respectively for replantation of the metacarpal position. If a broken finger occurs, it must be promptly collected and then quickly stop bleeding millions of hospitals, for the shortest possible time for surgical reattachment, to maximize the survival rate of the broken finger, to avoid the emergence of broken fingers for too long and necrosis, must be controlled in a timely manner to do.
