Traumatic spondylolisthesis of the axis (TSA) is defined as a fracture through the pars interarticularis of C2. TSA with anterior luxation of C2-C3 in the absence of neurological deficit is rarely seen. We aim to discuss treatment options for this condition in a subacute setting.
A 39-year-old female presented with neck pain and no neurological deficits following a car accident. CT showed a displaced C2 fracture through the pars interarticularis and she was initially managed with external immobilization [Figure 1]. The patient was then transferred to our center. After an unsuccessful external skull traction, the patient underwent posterior arthrodesis from C0 to C4 with subsequent external immobilization for 5 months [Figure 2]. At 10-year follow-up patient showed complete fusion of C2 and C3 without any signs of instability while remaining neurologically intact [Figure 3].

Delayed application of traction to this patient after the transfer to a tertiary center might explain the treatment failure. The wide gap between C2 and C3 represented a challenge for instrumented anterior arthrodesis and would also have put the patient to an additional risk of damaging the anterior neck structures. Facing technical limitations due to the significant C2 displacement and a patient's short neck, and after having ruled out anterior compression, a posterior occipito-C4 fusion was favored in the current case. Although this surgical strategy is regarded as less stable than a combined anterior-posterior arthrodesis, continued external immobilization over 10 weeks resulted in good fusion outcome in long term.
