Steel plate mostly refers to the internal fixation, clavicle fracture take out the internal fixation more than half a year pain may be due to local tissue adhesion, nerve injury, fracture non-healing and so on. 1. Local tissue adhesion: due to the removal of clavicle internal fixation, there will be a certain amount of trauma, causing local inflammatory reaction, resulting in adhesion of the surrounding soft tissues, resulting in pain. 2. Nerve damage: if the nerve is pulled during the surgery of removing internal fixation, causing nerve damage, due to the slow recovery of the nerve, the pain may still occur half a year after the surgery. 3. Fracture non-healing: after removing the internal fixation, several screw holes will be left in the clavicle, which need some time to recover, if combined with diabetes, severe osteoporosis and other underlying diseases, poor nutritional status, the fracture healing is slower, and half a year later, there may still be pain. There are many reasons for the pain six months after the clavicle fracture removal and internal fixation surgery, so it is recommended to consult a doctor in time to clarify the cause of the disease and carry out targeted treatment.
