Odontoid fractures in the pediatric population: a systematic review and management algorithm.

Abstract

Purpose: The management of odontoid fractures in adult patients has been widely described. However, there is sparse literature about this injury in the pediatric population. This study aimed to review published literature regarding the management and outcomes of pediatric odontoid fractures to develop a stepwise treatment algorithm.

Methods: A literature review was conducted using PRISMA guidelines on PubMed to identify studies between 1960 and 2023 that reported on the management and outcomes of odontoid fracture in pediatric patients. Studies were included if they were published in English and if their sample included at least four patients aged 0-18, minimum follow-up of 6 weeks, and outcomes for each patient clearly differentiated.

Results: In total, 15 studies including 125 pediatric patients with odontoid fractures were included. Treatment options varied from non-operative management with immobilization in rigid collars, halo vests, cervicothoracic orthosis, or soft collars to surgical management with fixation and/or arthrodesis. There were 73 patients initially treated nonoperatively, 47 initially treated surgically, 2 who healed with observation alone, and 3 who died acutely of concomitant injuries. The nonunion rate for nonoperative management was 5.5%. Surgery was successful, demonstrating bony union at final follow-up, in 94.6% of cases treated via a posterior approach and 85.7% of cases treated with an anterior approach.

Conclusions: Odontoid fractures must be considered in pediatric patients with cervical spine trauma. This is the largest literature review of pediatric odontoid fractures. Various management strategies exist and can be considered. The proposed algorithm offers an evidence-based framework for the management of pediatric odontoid fractures.
