Kirschner wire reconstruction of medial and lateral column periosteal hinge in the treatment of multidirectionally unstable supracondylar fracture of the humerus in children
European Journal of Medical Research(2023)
Abstract
Aim and objective To compare the clinical effect of reconstruction of internal and lateral column periosteal hinge-assisted treatment with Kirschner wire and internal fixation with Kirschner wire in the treatment of multidirectional unstable supracondylar fractures of humerus in children. Methods A retrospective cohort study was conducted to analyze the clinical data of 48 patients (31 male, 17 female; mean age: 6.7 ± 2.4 years old) with multidirectionally unstable supracondylar fractures of the humerus treated in our Hospital from August 2020 to August 2022. Twenty-five cases were treated with Kirschner wire reconstruction of the internal and lateral column periosteal hinge assisted by closed reduction and Kirschner wire internal fixation (study group). Twenty-three cases were treated with closed reduction and Kirschner wire internal fixation (control group). The operation time, intraoperative fluoroscopy times, percentage of patients who underwent open reduction after failure of closed reduction, fracture healing time, Baumann angle (BA), shaft-condylar angle (SCA), range of motion (ROM), and Flynn score of elbow at the last follow-up were compared between two groups. Complications such as infection and irritation of Kirschner wire tail were observed in two groups 2 months after the operation. Results All patients were followed up for 10–22 months ([13.85 ± 2.89] months). The average operation time of the control group was 82.1 min, which was significantly longer than that of the study group 32.3 min ( P < 0.05). The number of intraoperative fluoroscopy (29.4 ± 9.2) in the control group was significantly higher than that in the study group (15.2 ± 6.3) ( P < 0.05). The incision rate of the control group was 17% while that of the study group was 0 ( P < 0.05). According to Flynn score, the excellent and good rate of the elbow joint in the control group was 86.9% (20/23). The excellent and good rate of the elbow joint in the study group was 92.0% (23/25) ( P > 0.05). There was no significant difference in fracture healing time, BA, SCA, and ROM between the two groups ( P > 0.05). No infection or Kirschner wire tail irritation occurred in the two groups during the 2-month follow-up. Conclusion Reconstruction of internal and lateral periosteal hinges with Kirscher wire has similar effects to closed reduction and Kirschner wire fixation in the treatment of multidirectionally unstable supracondylar fractures of the humerus in children, but it can shorten the operation time and reduce intraoperative fluoroscopy times and incision rate.
