Stiffness of the finger after reimplantation of the broken finger may be due to the local postoperative immobilization for a long time, and stiffness occurs due to contracture of the soft tissue joint capsule. There is also the fracture involving the articular surface, appearing localized local bony fusion. Go to the hospital to see the doctor, the doctor combined with the preliminary analysis of the examination, the routine improvement of the finger X-ray to understand the healing of the fracture and whether there is a bony fusion leading to stiffness, according to the examination and then do the appropriate treatment. If the stiffness is caused by bony fusion, it is difficult to improve. If the stiffness is caused by joint contracture, it can be improved gradually if the fracture heals well, soak in hot water more often, and carry out finger bending training appropriately.
