There are always patients who ask why my wounds are always bad. What is the reason? What should I do? With the increasing use of surgery to treat fractures, post-operative complications are emerging. For fracture patients, post-operative wound infection is “catastrophic”. The wound does not heal and the plate screw is exposed, causing great pain to the patient. Generally speaking, if the internal fixation is left in the wound, the infection cannot be completely cleared and the wound cannot heal. It is possible that one day this wound will be healed and the next day another one will appear somewhere else. For infected fractures, the question of when to remove the internal fixation and what to do next is a great test for orthopaedic surgeons and is still a problem for orthopaedic surgeons worldwide. Because there is no one solution is a panacea.
