Nonmetallic posterior monosegmental cervical fusion of adislocated C6/7 fracture in a4-year-old girl : Acase report.

Abstract

Pediatric cervical spine injuries constitute approximately 1-2% of all pediatric trauma cases. Usually pediatric vertebral injuries appear as stable A type fractures, whereas B and C type injuries are relatively uncommon. In contrast to adults, the appropriate treatment strategy in children is still controversial and places spine surgeons in complex situations. This article reports the case of a4-year-old girl with an unstable B type injury at the C6/7 level (AOSpine C6-7: B2 [F4 BL, C7:A1]) with bilateral locked fractures of the facet joints after falling down aflight of stairs. Magnetic resonance imaging (MRI) and computed tomography (CT) were initially performed. The 4‑year-old girl was treated under intraoperative neurophysiological monitoring via open reduction after partial resection of both C7 upper articular processes and nonmetallic monosegmental posterior interlaminar fusion (FiberWire®) at the C6/7 level with temporary immobilization in ahalo brace. Clinical and radiological follow-up was carried out after 9months. The patient suffered no pain or neurological deficits. Plain radiographs revealed acorrect cervical alignment with anatomical correction of the initial dislocation. The treatment of highly unstable pediatric B type injuries of the lower cervical spine via open reduction and nonmetallic monosegmental posterior interlaminar fusion results in good clinical and radiological outcomes. Atemporary immobilization in ahalo brace provides stability until osseous fusion occurs.
