The sequelae of distal radius fracture, mainly manifested as motor-sensory dysfunction of the corresponding parts and osteoarthritis, are mainly these types: 1, carpal tunnel syndrome, mainly due to the displacement of the fractured end to the palmar side, resulting in the narrowing of the carpal tunnel space squeezing the median nerve, manifested as numbness of the skin of the three and a half fingers on the side of the thumb, weakened grip strength, and in severe cases will lead to atrophy of the greater pisiform. 2, ulnar carpal impingement sign, mostly seen in In middle-aged and elderly patients, due to shortening of the radius after fracture healing, the ulna and radius will hit each other when moving, which will cause pain in the wrist joint, and in severe cases, ulnar osteonecrosis will occur. 3.Traumatic arthritis, mostly seen in patients with crushing fracture, destruction of the wrist joint surface, uneven joint surface after fracture healing, and pain in the wrist joint. 4.Chondral cartilage injury of the wrist triangle, mostly seen in patients with distal radius fracture combined with ulnar styloid process. The pain is obvious when the wrist joint is rotated. 5. Reflex sympathetic dystrophy, which is mainly caused by inadequate postoperative functional exercise.
