What are the relevant examinations needed for patients with wrist swelling and pressure pain? Let’s take a look at the following: A fracture of the lower end of the radius is a fracture within 3 cm from the articular surface of the lower end of the radius, which is the junction of cancellous and dense bone, and is an anatomical weak point that is easily fractured once it is subjected to external force. The articular surface of the lower radius is concave from the dorsal to the palmar side and from the radial to the ulnar side, forming a palmar inclination (10 degrees-15 degrees) and an ulnar inclination (20 degrees-25 degrees) respectively. The ulnar side of the radial styloid process and the radial side of the ulnar tuberosity form the ulnar radial joint, which, together with the superior ulnar radial joint, forms the anatomical basis of the rotational activity of the forearm. The stem is located 1-1.5 cm far from the plane of the ulna, and the lower end of the ulna and radius together form the proximal column of the carpal bone to form the carpal joint. The main manifestations are swelling and pressure pain in the wrist, and limitation of hand and wrist activities. Wrist triangle cartilage squeeze test: wrist triangle cartilage squeeze test is to the affected hand to the ulnar tuberosity direction constantly jacking, check whether pain occurs, used to diagnose the wrist triangle cartilage injury, can consider the injury of the triangle cartilage, ulnar stem fracture. There is no inappropriate population for wrist triangle cartilage squeeze test, relax during the examination, face positively and cooperate with the examination. Wrist extension test: wrist extension test is to maintain the wrist in the hyperextended position and check whether there is pain, which is used to diagnose carpal tunnel syndrome. Bone densitometry: For osteoporosis due to various causes, it is highly sensitive and has a high diagnostic rate. Bone densitometry is useful to assist in the diagnosis of osteoporosis. Bone mineral density (BMD) is the most effective predictor of fracture risk, and the risk of fracture is geometrically related to BMD. Changes in bone mineral density (BMD) can be monitored with a bone densitometer. Orthostatic spine and/or bilateral femur are generally used, and bilateral femoral scans are more meaningful when the patient has significant spine augmentation or deformation. Bone imaging: Diagnosis of bone tumor and bone metastasis tumor can be made 3-6 months earlier than X-ray examination, but it should be noted that this method is highly sensitive and low specificity. CT examination of bone, joint and soft tissue: It is a method to examine bone, joint and soft tissue by CT. It is mainly for injuries and diseases of bones, joints and soft tissues. It is suitable for patients who suffer from bone, joint and soft tissue diseases.
