What is the jaw joint?

The anatomical structure of the lower jaw joint is complex, consisting of the iliac crest, the bony structure at the distal end of the humerus, and the iliac joint ligament complex (Fig. 1). The ligament complex includes the anterior and posterior tibiofibular ligaments and the interosseous ligament. The anterior and posterior ligaments firmly fix the humerus in the iliac crest of the humerus, and adjust the shape of the acupoint together with the interosseous ligament to maintain its compliance and stability.

 What are the hazards of the joint injury of the ankle joint?

Recently, studies have shown that the proportion of squat joint injury in acute ankle sprain is as high as 17% to 74%. In all occupations, the incidence of young athletes is the highest, and the ankle ligament injury that occurs in young athletes accounts for 10% to 30% of sports injuries. 59% of athletes with ankle ligament injury, there will be stubborn sequelae, such as pain, swelling, joint stiffness, self-feeling ankle instability, 40% of people due to injury caused by chronic ankle instability; long-term chronic ankle joint Unstable, talus cartilage damage and traumatic arthritis. Therefore, for the ankle ligament injury, early diagnosis and reasonable treatment should be carried out.

How to diagnose and treat the joint injury of the ankle joint?

(1) The joint injury of the ankle joint is mainly diagnosed by combining medical history, symptoms, MRI examination and comprehensive physical examination.

 (2) Treatment is divided into conservative treatment and surgical treatment. Most conservative treatments for acute injury without combined sputum separation can be cured, and William et al. recommend a three-stage treatment. Stage I Brake, Pain Relief, Detumescence, Limited Load, POLICE Principle; Stage II Pain and swelling improve, walk on the basis of pain control, exercise strength and proprioception, progress from low intensity to high intensity repetitive exercise until no Symptoms; Stage III includes rigorous strength training and specific exercise-related exercise to restore the original level of physical activity.

 Surgical treatment should be actively performed for unstable sacral joint injuries. The surgical procedure is mainly internal fixation, which can be combined with suture ligament or ligament transplantation to reconstruct the lower iliac ligament. Clinically, we often use the local anesthesia lag screw, absorbable screw, Suture-button system internal fixation, etc., the patient can be discharged in a short time.
