For patients who present with an ankle fracture, immobilization of the affected area in a cast for about 4 weeks is required. Patients with ankle fractures, whether treated conservatively or surgically, are often immobilized in a cast for about 4 weeks. Most patients, when properly treated, will achieve clinical healing of the fracture after 4 weeks. Thereafter, the ankle can be exercised accordingly. Of course, there are some exceptions. For example, if the patient’s lesion is particularly mild, or if the ankle has been surgically immobilized, the external fixation device can be removed about 2 weeks after cast immobilization, and the patient can be instructed to perform non-weight-bearing functional exercises. In some patients who have been treated conservatively, healing may not be achieved at 4 weeks due to excessive trauma or premature activity. Continued external immobilization in a cast or elective surgery may be required. It is recommended that patients with ankle fractures should be kept in a state of immobilization during the treatment period, as prescribed by the physician. After about 4 weeks of recovery, the patient should return to the orthopedic department for follow-up. If it is confirmed that the fracture has healed well, the external fixation device can be removed in time and functional exercises can be carried out to prevent the emergence of joint adhesion.
