Wrist pain and swelling and limitation of palmar flexion activities occur most often in patients with distal radius fracture, with wrist pain and swelling, especially limitation of palmar flexion activities. Wrist pain and swelling and limitation of palm flexion activities are mostly caused by indirect external force, when falling, the elbow is straightened, the forearm is rotated forward, the wrist is extended dorsally, and the palm of the hand lands on the ground. The stress acts on the distal radius and a fracture occurs. The dorsal aspect of the wrist bulges and the palmar aspect protrudes. The outline of the ulnar tuberosity disappears. The wrist widens and the hand is displaced to the radial side. The lower end of the ulna protrudes and the radial styloid is displaced upward to or beyond the level of the ulnar styloid. Pressure pain at the distal end of the radius, palpable fracture end displaced to the radial dorsum, palpable bone rubbing sound in comminuted fracture, etc. Clinical examination shows: pain and swelling of the wrist, especially limited palmar flexion activities. If the displacement of the fracture is severe, there may be a forked deformity, i.e., the dorsal aspect of the wrist is elevated and the palmar aspect is prominent. The outline of the ulnar tuberosity is lost. The wrist widens and the hand is displaced to the radial side. The lower end of the ulna protrudes and the radial styloid moves up to or beyond the level of the ulnar styloid. There is pressure pain at the distal end of the radius, the fracture end displaced to the radial dorsum can be touched, and bone rubbing sound can be touched in comminuted fracture. Patients should be timely early hospital for treatment, the prognosis should be early to carry out correct functional exercise, patients should overcome the fear of pain and swelling due to functional exercise, fear of fracture dislocation concerns. Under accurate repositioning and localized firm external fixation, early functional exercise of the affected limbs should be carried out. Passive activities should be carried out first, then active activities, and the functional exercise should be gradual. On the day of fixation, you can move your finger joints, make and release your fist, gradually increase the number of activities, and do the flexion and extension of the shoulder and elbow joints at the same time. After the fracture is healed, it should be excluded from the immobilization as soon as possible, with physical therapy, comprehensive shoulder, elbow, wrist joint activities, especially to strengthen the exercise of clenching and unclenching, to restore the muscle strength and muscle coordination, and to prevent the dysfunction caused by muscle atrophy.
