The sequelae of hand bone fracture mainly include: 1. damage to the surrounding vascular nerves and tendons. After the fracture, due to the sharp end of the fracture, it is easy to stab the surrounding tendon nerves and blood vessels, resulting in finger extension and flexion dysfunction, numbness and weakness, no feeling in the fingers, and massive bleeding. 2. Joint stiffness. The fracture needs to be fixed for a long time, and the adhesion of the surrounding tissues will lead to impaired finger extension and movement. 3. Traumatic arthritis. Especially the fracture site at the hand joint, with the prolongation of time, further activities are likely to induce arthritis. 4.Acute bone atrophy. Painful osteoporosis near the joint caused by the injury, the typical symptoms of which are pain and vasodilatory disorders. 5, local deformity of the hand. Commonly seen in patients with conservative treatment, or premature activity after surgery with displacement, is caused by deformed healing of the fracture.
