Ankle fracture five and a half months ankle still hard may be due to joint adhesion, not timely rehabilitation training and other reasons, the treatment mainly includes conservative treatment and surgical treatment. 1. Conservative treatment: Rehabilitation training is still the main means to relieve joint adhesion and stiffness, mainly including ankle joint extension and flexion, internal and external rotation function, etc., 3~5 groups per day, 15~20 times per group, step by step; secondly, localized heat therapy, massage, fascia gun and other ways can be carried out to assist. For patients with muscle stiffness, appropriate muscarinic drugs such as etoperisone hydrochloride are given. The above drugs need to be used under the guidance of a doctor to avoid self-medication. 2. Surgery: If there is no significant improvement after conservative treatment, and the ankle joint has developed extensive adhesions or even contractures, surgical release can be considered. The purpose of surgical release is to restore the mobility of the joint, but the surgery itself will also cause adhesion, so early rehabilitation training is still needed after the surgery to achieve the purpose of treatment. If the stiffness of the ankle and wrist is not relieved or is accompanied by other symptoms, the patient should go to the hospital in a timely manner to clarify the cause of the stiffness and then give targeted treatment.
