Area of Science:

  • Orthopedic Surgery
  • Neurosurgery
  • Traumatology

Background:

  • Posterior dislocation of the atlas (C1) onto the axis (C2) without odontoid fracture is an exceptionally rare spinal injury.
  • Only five cases have been previously documented in medical literature, making it a significant diagnostic and therapeutic challenge.

Observation:

  • The authors report the sixth documented case of this rare condition.
  • The patient presented with posterior C1-C2 dislocation, notably without any associated fracture of the odontoid process.

Findings:

  • The presented case was managed differently from previously reported instances.
  • Successful treatment was achieved through open reduction of the dislocation followed by C1-2 transarticular screw fixation.
  • This approach ensured safe intraoperative reduction and stable fixation.

Implications:

  • This case underscores the importance of considering rare diagnoses in spinal trauma.
  • The successful surgical technique provides a potential management strategy for similar rare dislocations.
  • Further investigation into diagnostic modalities and treatment outcomes for this specific injury is warranted.
