Tightness in internal fixation of tibiofibular bone may be caused by local swelling, local bleeding, over-tightening of bandage and so on. 1. Local swelling: because tibiofibular fracture is often accompanied by peripheral tissue damage, patients may appear local edema, oozing and other changes, after internal fixation suture wound, the tension is greater, patients may feel obvious tightness. 2. Local bleeding: often occurs in patients with bleeding after internal fixation surgery, patients may appear local oozing, swelling, patients may feel obvious tightness. 3. Tight bandage: Because of the need for plaster fixation and bandage after tibiofibular internal fixation, if the bandage is too tight and causes high pressure in the fascial cavity, the patient may feel obvious tightness, which may lead to osteofascial compartment syndrome in severe cases. If the tibiofibular internal fixation tightness is not relieved, you should consult a doctor in time to clarify the cause of the disease, under the guidance of the doctor for treatment.
