Suggestion: illness analysis: hello, you have a leg fracture, and you have done open reduction and internal fixation. After the operation, your leg is swollen and your ankle is limited. Consider: 1. The degree of fracture is serious, which may be a fracture, and it is difficult to operate during the operation. Excessive separation of periosteum and severe local soft tissue injury will lead to poor blood circulation of your lower limbs after operation, resulting in swelling of your lower limbs. When the circulation is slowly established, plus proper exercise, the swelling will disappear. After plaster external fixation for a period of time, the joint mobility decreases, which leads to joint stiffness. This is a very normal phenomenon, so don't worry too much. You can slowly recover the joint mobility after functional exercise! Suggestion: It is suggested to reduce the sagging of lower limbs and exercise ankle and knee joints more to prevent stiffness. In addition, drugs that can reduce swelling, remove blood stasis and promote callus growth can be taken orally, but at present, they can't bear weight on the ground. Pay attention to this!
