Management of post-traumatic neglected cervical facet dislocation.

backgroundPost-traumatic unilateral or bilateral sub-axial cervical spine dislocations with locked facets are quite common. In developing countries like India, many patients with cervical injuries report late due to many reasons like rural backgrounds, lack of infrastructures and skilled surgeons, unawareness, poor socioeconomic status, lack of transportation to the specialized center with proper facility, etc. Early management is essential to maximize better neurological outcome. Delayed or neglected presentation makes treatment more challenging. Very few literatures are currently available regarding management of neglected cervical facet dislocation but no one offers clear cut management. Purpose of our study is to evaluate treatment outcome of 15 patients with post-traumatic neglected cervical facet dislocation. Here we have reviewed 15 patients with post-traumatic neglected presentation of cervical facet dislocations and evaluated their treatment outcome. MATERIALS AND

methodsThis is a retrospective type of study done in spine care unit of VMMC and Safdarjung Hospital, New Delhi from July 2013 to June 2016. Record of 15 patients with neglected cervical dislocation who were undergone anterior cervical discectomy and fusion along with posterior lateral mass screw fixation depending upon close reduction and integrity of disco-ligamentous complex.

results15 patients were included in this study. 4 patients underwent only anterior cervical discectomy and fusion (ACDF) after complete close reduction with intact disco-ligamentous complex. Remaining 11 patients who failed to achieve complete reduction or had posterior disco-ligamentous injuries underwent posterior partial facetectomy and lateral mass screw fixation with anterior discectomy and fusion concomitantly. Mean follow up period was 14 months. All patients achieved pain relief and sufficient neck movements. 1 patient with only nerve root injuries recovered completely. 6 out of 11 patients with incomplete spinal cord injuries, improved by one Frankel grade and remaining 5 patients by two grades. 3 patients with complete quadriplegia showed no clinical and neurological improvement.

conclusionProper decompression, reduction and fixation should be done in neglected cervical dislocation as it provides mechanical stability and alignment, facilitates rehabilitation, prevent kyphotic deformity as well as offers a fair chance of neurological recovery.
