Ankle sprains have a high incidence, accounting for more than 80% of systemic joint sprains. Clinically, inversion injury (external ankle sprain) is the most common. 1. Diagnosis 1.1 Clinical manifestations 1.1.1 Symptoms: History of acute sprain, obvious swelling and pain at the ankle, inability to land, obvious pressure pain and local subcutaneous bruising at the injury site. In case of external ankle sprain, if the ankle joint is turned inward, the pain in the external ankle will increase; in case of injury to the lateral joint capsule and the anterior peroneal ligament, the swelling is mainly on the lateral side of the joint and below the front of the external ankle. In case of internal ankle sprain, it may be accompanied by external ankle fracture, so both internal and external ankles are swollen and painful, and should be examined carefully. 1.1.2 Signs 1.1.2.1 Pressure pain: pressure pain points are obvious, mostly at the ankle joint gap, and generally the pressure pain is the site of injury. 1.1.2.2 There is swelling and subcutaneous bruising. 1.1.2.3 Activity function: all have different degrees of impairment. 1.2 Diagnostic criteria 1.2.1 There is a clear history of sprain. 1.2.2 There is obvious local pressure pain and palpable changes of local muscle tension 1.2.3 There is swelling and subcutaneous bruising. 1.2.4 X-ray examination: it has no direct significance to the diagnosis of this disease, and is mainly used to exclude fracture and dislocation, etc. 2. Identification This disease is all due to the sudden inward or outward turning of the ankle joint when walking, running, jumping, or descending stairs on an uneven surface, and the lateral or medial ankle ligaments are under strong tension. The local tendons are damaged, the blood overflows outside the veins and swelling occurs, stasis of blood blocks the ligaments, and pain is caused if it does not pass. 3. Treatment 3.1 Principle of treatment: Activate blood circulation to remove stasis, relieve swelling and pain, and rehabilitate the joint. 3.2 Techniques: pushing with one finger, kneading, pointing, pressing, holding, rubbing, plucking, wrenching, etc. 3.3 Acupuncture points: foot three miles, Yanglingquan, Jiebei, Xiexi, Kunlun, Qiuhui and other points. 3.4 Operation: patient in supine position. Press and rub gently along the lateral side of the affected calf, from the knee to the ankle several times. Point and press the above acupuncture points to clear the qi of the meridians. Use gentle one-finger meditation pushing and pressing and kneading to treat the injured area for 5 minutes to reduce swelling and dissipate stasis. At the same time, combine with the ankle joint shaking method, the amplitude from small to large. Then, the ankle joint is extracted and stretched manually. The doctor holds the heel of the affected side with one hand, holds the palm of the foot with the other hand for traction, and does the ankle joint shaking under traction. The ankle joint disorder is regulated. Finally, the affected area is treated with rubbing method, to the extent of heat penetration. 3.5 Other therapies 3.5.1 External application of medication: blood activating powder is applied externally. 3.5.2 Drug patching: commonly used are dog skin ointment, Qizheng pain relief patch, Doc’s self-heating patch and blood-vitalizing bone joint patch. 3.5.3 Acupuncture and moxibustion therapy: it has good curative effect, and it works better with Tui Na. 3.5.4 Closed therapy: fast effect, easy to turn chronic and leave chronic pain. Massage method is only applicable to simple muscle and ligament sprain or partial fiber rupture of ligament in ankle joint. Massage is not recommended for complete ligament rupture, dislocation and fracture. During the acute injury period, the technique should be gentle so as not to aggravate the injury; hot compresses should not be applied within 24 hours of injury. The recovery period should be slightly heavier, especially for the hematoma mechanization, adhesions, should be heavier techniques to make adhesions loosened.
