Cervical Spine Dislocation

 

C5 displacement over C6 , (displacement > 50 % , it's a Bifacet dislocation )

Delayed Diagnosis of B/l facet dislocation :a case report.Julie O Shaughnessy et. al.

Only shows C7 and is inadequate for trauma C-spine lateral radiograph. 


Management 

    - ATLS guideline -remove helmet visor to gain access to eyes , nose and mouth.

    - Exclude other injuries.

    - Full imaging of spine / full neurological examination - ensure this is isolated injury.    

    - Spine surgery consultation for reduction 

                    Close or Open 

    - Exclude a prolapsed disc which damages cord during reduction.

    

         If no MRI scanner, can we reduce with patient awake ?

        Yes, we can reduce. We can monitor patient awake, alert .Serial neurological examination is also             possible.

         Gardner-Wells-Tong / Crutchfield skull traction is applied on skull and then adding sequential                 weights to traction cord.

        Patient positioned on supine, under C-arm guidance, after each addition of weight load, image                 taken and assessed. Initially 10 pounds then 5 pounds added. Once neck is fully stretched, facets             unlocked then neck is fully extended to complete the reduction and traction reduced. 

        How do we apply a Halo traction Jacket?

        Take the consent.

        Four pins using local anaesthesia applied on skull, tightened with a torque limiter (6 pins for                     children)

        Placement carried out as follows - 

         1. Anterior - 1 cm above lateral outer 1/3rd of eyebrow

         2. Posterior - Behind earlobe above mastoid 

        Three Person Job- one holding head and two applying Halo.

        Apply Jacket of approximate size.

        Check radiograph of spine to ensure correct reduction.

        Tighten pins after 24 hours.

  Complications 

        Loss of reduction 

        Pin site infection and Loosening 

        Pain

        Nerve Injury
