Wrist swelling and pain and limited palmar flexion activities are caused by traumatic factors, no special preventive measures, the prevention and treatment of the disease, focusing on the prevention of complications, the gram period is the elderly, the main points are as follows: 1, timely outpatient review: review time is generally to review every 2 days in the first week, 1 week after the review once a week. Firstly, check the bandage tightness and swelling, and adjust the tightness of the splint bandage and plaster clip according to the swelling of the wrist and forearm at any time when the fracture is fixed. 4 weeks after the X-ray shows that the fracture is healed, the fixation can be released and functional exercise can be actively carried out. Prevent tendon and nerve injury: Generally, when fixing a Creutzfeldt-Jakob fracture, it is mostly fixed in palmar flexion and ulnar deviation, which can increase the pressure in the carpal tunnel, and some of them can easily compress the median nerve. 3, early should control the rotation front displacement: fixation should keep the affected limb in the post-rotation 15 ° position or neutral position. Pre-rotation fixation often restricts the forearm rotation function, should be corrected in time, put back to the post-rotation position, otherwise it will affect the rotation function of the forearm. 4, early and correct functional exercise: Patients should overcome the fear of pain and swelling due to functional exercise and worry about fracture dislocation. Under accurate repositioning and firm local external fixation, carry out functional exercise of the affected limb as early as possible. The passive activities should be carried out first, and then the active activities, and the functional exercises should be carried out gradually. On the day of fixation, you can move the finger joints, clench and loosen the fist, and gradually increase the number of activities, while doing flexion and extension exercises of the shoulder and elbow joints. After the fracture heals, you should remove the fixation as soon as possible, cooperate with physical therapy, do all kinds of activities of shoulder, elbow and wrist joints, especially strengthen the exercise of fist clenching and fist loosening, restore the muscle strength and muscle coordination function, and prevent the dysfunction caused by muscle atrophy.
