Successful delayed non-operative management of C2 neurosynchondrosis fractures in a pediatric patient: a case report and review of management strategies and considerations for treatment.
Upper cervical synchondrosis fractures are the most common types of cervical fractures in the pediatric population less than 7 years of age (Blauth et al (Eur Spine J 5:63-70, 1996); Connolly et al (Pediatr Radiol 25(Suppl1):S129-133, 1995); Mandabach et al (Pediatr Neurosurg 19(5):225-232, 1993); Schippers et al (Acta Neurochir 138:524-530, 1990)) The vast majority occur through the dentocentral or basilar synchondrosis. We present the second reported case in recent literature of a unilateral neurosynchondrosis fracture. The patient, a 4-year-old male, was initially managed conservatively with a rigid cervical collar for a period of 3 months. Despite multiple counseling sessions with family, the patient remained poorly compliant with cervical immobilization. After 3 months, imaging demonstrated partial fusion with persistent anterolisthesis of C2 on C3. The decision was made to place the child in external halo fixation as an attempt to achieve fusion prior to committing to internal surgical fixation and the associated sequelae. Immobilization with a hard cervical collar is often first line treatment. In the case of failed fusion, debate exists regarding surgical fixation in children. Occipito-atlanto-axial fusion leads to permanent loss of a significant degree of flexion, extension, and rotatory movement. The pediatric population has a strong propensity to fuse; however, compliance is often a barrier to conservative treatment due to age-related behavioral practices. We demonstrate that even with initial failed fusion and progression of deformity while in a cervical collar, conservative management with external halo fixation can potentially obviate the need for internal fixation.
