The precautions after removing the tibiofibular union screw mainly include prohibiting strenuous exercise in the short term, observing the changes around the incision, and diet. 1. Tibiofibular union screw is usually used for patients with ankle fracture combined with separation of tibiofibular union. After removing the internal fixation, strenuous exercise should be avoided for one month as a rule. 2. Because the blood circulation of the lower limbs is relatively poor, and the healing of the nail holes is longer than that of other parts of the body, short-term strenuous exercise and too much weight-bearing may lead to secondary fractures and non-healing of the nail holes. 3. After removing the screws, the healing time of the incision is generally about 12~14 days, during which time you should avoid water, and try to choose a sterile dressing to cover the incision before scabbing. 4. If the incision oozes more, the skin surface is red and swollen, it is necessary to timely follow-up. 5. During the healing period, try to eat a light diet, avoid spicy, cold and raw food stimulation, and try to avoid alcohol and tobacco.
