Wrist navicular bone old fracture more than 20 years can still be cured. The old fracture of the navicular bone of the wrist is not healed because the fracture was not well maintained at that time. For old stable fracture, if the sclerosis and bone resorption of the fracture ends are not obvious, it can be fixed with plaster, but if the fracture has been broken for more than 20 years, usually the fracture ends will have been resorbed and sclerosis, conservative treatment is not effective, and if you need to treat it, you need to carry out surgery. For old unstable fractures, surgery can be performed with incision and reduction and internal fixation with bone grafting. To prevent the development of traumatic arthritis, the radial tuberosity is resected and the residual space can be filled with a tendon mass. For nonunion with combined arthritis, fusion of the navicular head, cephalolunate interphalangeal joint, or carpal fusion can be performed. Old fractures of the navicular bone of the hand for 20 years may cause biomechanical changes in the wrist joint and affect wrist function.
