Activity-restriction only as treatment yields positive outcomes in pediatric spinal compression fractures: a prospective study of 47 patients at medium-term follow-up
Abstract
Background and purpose: We aimed to evaluate the clinical outcomes, radiographic results, and health-related quality of life in pediatric AO type A1 spinal compression fractures treated with activity-restriction only. Patients and methods: All children between 2014 and 2020 with an AO type A1 spinal compression fracture treated with activity-restriction only identified from an institutional fracture registry were invited to a prospective outcomes study. Clinical findings and spinal radiographs were assessed at median 3 years, interquartile range (IQR) 1–4 follow-up from injury. Oswestry Disability Index, Pediatric Quality of Life Inventory Generic Core Scale (PedsQL), and PedsQL Pediatric Pain Questionnaire were compared with reference values. 63 children were identified, of whom 47 agreed to participate. 8 were polytrauma patients. Results: Age at injury was median 11 (IQR 9–14) years. The number of injured vertebrae was median 2 (IQR 1–3). 82% (94 of 115) were thoracic vertebrae fractures and 70% (33 of 47) of the patients had thoracic vertebrae fractures only. At follow-up all but 2 fractures showed radiographic remodeling. There was no difference from the published reference values in the patient-reported outcome measures. A lower PedsQL physical functioning score was associated with higher patient-reported pain (P = 0.03). At follow-up 12 patients had hyperkyphosis (median difference from the reference values 4°, IQR 3–6, 95% confidence interval [CI] 3–6) and 5 hypolordosis (median difference from reference 8°, IQR 4–11, CI 4–14). None of the patients had surgery for deformity during follow-up. Conclusion: Clinical, radiographic, and health-related quality of life outcomes were good after activity-restriction treatment in pediatric A1 spinal compression fractures.
