Background:
The cervical spine represents the most common site of spinal trauma, typically associated with vertebrae dislocation with locked facets. Accurate assessment of the entire spine is essential to prevent diagnostic and therapeutic failures. Here, we present a case of a patient with C6-C7 dislocation who underwent two unsuccessful surgical procedures, highlighting the technical challenges associated with revision surgery and persistent facet locking.
Case Description:
A 26-year-old male arrived at an emergency hospital after a motorcycle accident with paraplegia, C6 roots strength grade 2, and C7, C8, and T1 paralysis. The cervical computed tomography scan revealed C6-C7 dislocation, left C7-T1 locked facet, and right C6-C7 facet subluxation. After two unsuccessful surgical procedures, a combined 540-degree posterior-anterior-posterior (P-A-P) approach was performed. After the combined P-A-P cervical spine approach, the patient remained paraplegic, with no further neurological deterioration during follow-up.
Conclusion:
Early diagnosis and management of locked facets is crucial to avoid unstable constructions and subsequently hardware failure in patients with cervical spinal trauma.
