Atlantoaxial dislocation with associated type II odontoid fracture in adolescent with cervical spondylitis tuberculosis: A case report

Introduction and importance: Atlantoaxial dislocation is a loss of joint stability between the C1 (atlas) and C2 (axis) spine and could be associated with type II odontoid fracture. In a few previous studies, atlantoaxial dislocation with odontoid fracture has been reported to be the complication of upper cervical spondylitis tuberculosis (TB).Case presentation: A 14-year-old girl came with sudden neck pain and difficulty moving her head that has worsened in the last 2 days. There was no motoric weakness in her limbs. However, tingling in both hands and feet was felt. X-ray examination showed atlantoaxial dislocation with odontoid fracture. Traction and immobi-lization using Garden-Well Tongs obtained the reduction of the atlantoaxial dislocation. Transarticular atlan-toaxial fixation using cerclage wire and cannulated screw with an autologous graft from the iliac wing was performed through the posterior approach. A postoperative X-ray showed stable transarticular fixation with excellent screw placement.Clinical discussion: The application of Garden-Well tongs as a treatment for cervical spine injury has been documented in the previous study with a low rate of complications such as pin loosening, the asymmetrical position of the pin, and superficial infection. The reduction attempt did not significantly improve Atlantoaxial dislocation (ADI). Thus surgical treatment of atlantoaxial fixation using cannulated screw and c-wire with the application of an autologous bone graft is performed.Conclusion: Atlantoaxial dislocation with an odontoid fracture in cervical spondylitis TB is a rare spinal injury. The use of traction with surgical fixation is needed to reduce and immobilize atlantoaxial dislocation and odontoid fracture.
