Abstract

Abstract: Rationale: Adolescent wrist trauma can cause epiphyseal dysplasia and even distal radius deformity malunion. At present, there is no uniform treatment standard for the malunion of the distal radius of adolescents. Osteotomy and autologous bone grafting are currently one of the effective ways to treat the disease. We treated an adolescent patient with distal radius deformity malunion, and used this surgical method to treat the patient and achieved satisfactory results. Patient concerns: A 16-year-old boy suffered from a serious distal radius deformity after trauma of the left wrist 8 years ago. Diagnoses: Physical examination, X-rays examination, high-resolution computed tomography scan, and 3-dimensional reconstruction images of the affected limb helped us diagnose the distal radius fracture malunion. Interventions: The fracture malunion was treated by osteotomy and autologous iliac bone grafting. Outcomes: At the 2-year follow-up, wrist flexion returned to 68°, wrist dorsiflexion to 55°, radial deviation to 14°, ulnar deviation to 12°, forearm pronation to 75°, supination to 67°. Grip strength increased to 35.1 kg after 2 years of operation, recovered to 87% of the uninjured side. Quick DASH score at 2-year follow-up was 9. No complication, such as nonunion or infection, was observed. Lessons: This rare case provides valuable insights for hand surgeons. High-resolution computed tomography scan and 3-dimensional reconstruction can help us effectively diagnose wrist diseases. Small lesions on the articular surface of the distal radius will change the position and function of the wrist joint, and cause traumatic arthritis of the wrist joint. Therefore, it is very important to reconstruct the normal structure of the distal radius articular surface. Osteotomy and autologous iliac bone grafting are effective treatments for serious distal radius fracture malunion in the adolescent patient. During the operation, care should be taken to protect the osteoepiphysis to avoid bone dysplasia.
