Abstract:
Objective:To investigate the efficacy of intramedullary plus extramedullary fixation in the treatment of fractures of distal radial diametaphyseal transition zone in children.Methods:The data were retrospectively analyzed of the 49 children who had been admitted to Pediatric Orthopedic Hospital, Honghui Hospital Affiliated to Xi'an Jiaotong University from July 2018 to April 2020 for fractures of distal radial diametaphyseal transition zone. There were 30 males and 19 females; 21 left sides, 27 right sides, and one case of bilateral sides. In the operation, an elastic intramedullary nail or Kirschner wire was used for intramedullary fixation while another Kirschner wire was used to fix the cortex at the distal and proximal ends of the fracture. The ranges of wrist motion and Disabilities of the Arm, Shoulder and Hand (DASH) scores at 1 and 9 months after operation were recorded and compared; the incidence of postoperative complications was also recorded.Results:The operation time for the 49 children averaged 45.0 min (from 39 to 51 min). The patients were followed up for 6 to 36 months (mean, 18.6 months). The fracture union time averaged 8.6 weeks (from 6.8 to 10.4 weeks). Needle tract infection developed in one case but the wound was healed after removal of the K-wire after callus formation and oral use of antibiotics for 3 days. Another case reported skin irritation the symptoms of which disappeared after the child reduced activities. The ranges of pronation, supination, flexion and extension of the wrist and DASH score were 47.9°±2.5°, 45.5°±3.0°, 51.2°±1.6°, 53.4°±1.7° and (36.7±4.5) points at one month after operation while they were 85.6°±3.1°, 87.6°±2.1°, 88.8°±2.0°, 88.0°±1.2° and (23.2±8.6) points at 9 months after operation. There were statistically significant differences in the above indexes between one and 9 months after operation ( P<0.05). Conclusion:In the treatment of fractures of distal radial diametaphyseal transition zone in children, intramedullary plus extramedullary fixation is simple in surgical techniques, easily repeatable, slightly invasive, and reliable in fixation.
