Fractured joints can recover from stiffness for more than four months. It may be caused by different reasons. The main treatments include improving circulation, improving functional activities and surgery. 1. Improve circulation: If the stiffness of four months after fracture is caused by poor blood flow in the veins of the limbs, it is necessary to improve the circulation treatment. You can soak your feet in hot water, apply local hot compresses and infrared irradiation to improve local blood circulation, which can accelerate blood return and reduce the swelling of the limb, and at the same time, you can actively carry out the training of joint function. 2. Improvement of functional mobility: It is possible that the stiffness of the joints may occur because the functional exercise is not timely and thorough at the early stage of the fracture. It is necessary to strengthen the functional exercise, including dorsiflexion, plantarflexion, inversion and exversion of the joints, and carry out active and passive functional exercise to stretch the ligaments around the joints, which can improve the functional mobility. 3. Surgery: If the ligaments around the joint have obvious adhesion and contracture, surgery can be performed to loosen the joint to improve the stiffness. It is recommended that patients with fracture joint stiffness should go to the hospital in time for symptomatic treatment under the doctor’s guidance.
