With the progress of society, the popularization of medical knowledge, the development of medicine and the acceleration of the pace of life, people’s understanding of orthopedic diseases has also changed. 1.Distal radius fracture The distal radius fracture is commonly found in elderly patients with osteoporosis, and the mechanism of injury is hand bracing when falling, causing wrist deformity, pain and mobility impairment. Since the elderly do not require high mobility of the wrist joint, the traditional treatment is manual repositioning and external fixation in splint or cast. Generally, the fracture can be healed. However, a large number of follow-up surveys have shown that conservative treatment suffers from complications such as fracture collapse deformity healing, wrist stiffness, and limited finger flexion and extension, and these complications lead to pain that bothers patients and prompt a rethinking of treatment modalities. Incisional internal fixation of distal radius fractures allows early movement of the fingers and wrist to avoid joint stiffness; the possibility of fracture collapse is also greatly reduced due to the support of the plate. The procedure is gradually being accepted by everyone. 2.Ankle fracture Simple fracture of the inner and outer ankle is generally not taken seriously by patients because the bone is small, and they think that the doctor has to operate to treat such a small bone, so they are crazy to make money. In fact, this is not the case. The ankle joint consists of the lower end of the tibia and fibula and the talus. Its fracture and dislocation are common injuries in orthopedics, mostly occurring after ankle sprain caused by indirect violence. Depending on the direction and size of the violence and the position of the foot at the time of injury can cause a variety of different types of fractures. The treatment of ankle fracture is reflected in two aspects: (1) Ankle fracture without obvious displacement is mostly treated with cast fixation and braking, and the duration of fixation is usually about 3 months. However, after the fracture heals after 3 months, the ankle joint becomes stiff and requires a lot of time and effort to restore the mobility of the joint. The functional rehabilitation time even exceeds the fracture healing time. Therefore, some of them choose surgical treatment, which is traumatic and costly, but it can perform early ankle movement and avoid complications such as long-term ankle stiffness and muscle atrophy. (2) Because of the diversity of ankle fracture mechanisms, the judgment of fracture is also more complicated. Traditional X-rays have obvious limitations in diagnosing injuries such as fractures with insignificant displacement, lower tibiofibular joint separation, deltoid ligament, and lateral ligament. With the continuous improvement of medical examination technology, the movement of CT, MRI and other examination means has greatly improved the positive rate of ligament soft tissue injury and occult fracture. 3, osteoporotic compression thoracolumbar fractures Elderly patients are prone to thoracolumbar compression fractures after trauma, the root cause of which, in addition to trauma, is their own bone loss and osteoporosis. Traditionally, for compression fractures that are not obviously compressed, bed rest and elevation of the fracture site are feasible for conservative treatment. Due to the special characteristics of elderly patients, it is clinically found that there are serious complications related to bed sores, urinary tract infections, deep vein thrombosis, pneumonia, etc., associated with long-term bed rest. The fracture is not terrible, but the complications caused by the fracture are life-threatening. And the current medical conditions can completely relieve these troubles. The percutaneous vertebral retroconvex plasty invented specifically for osteoporotic thoracolumbar compression fractures and spinal occupation is a good solution to the problem of surgery. 4.Other fractures such as intertrochanteric fracture of femur, fibula fracture, clavicle fracture, etc., have been treated surgically due to the limitations of various conservative treatments.
