ABSTRACT
PURPOSE: Trauma to the lower cervical spine is a serious lesion due to its neurological consequences which jeopardize the vital and functional prognosis. They constitute a public health problem due to their frequency and seriousness requiring rapid and adequate treatment. The aim of our study is to (1) describe the epidemiological, clinical, and radiological characteristics of lower cervical spine trauma patients; (2) support the therapeutic management of these patients and show our experience in surgery for lower cervical spine trauma; and (3) analyze the anatomical and functional results and discuss them with literature data. METHODS: This is a retrospective descriptive study of 50 patients with lower cervical spine trauma treated surgically over a period of five years from January 1, 2016, to December 2020. RESULTS: The average age of our patients was 34.5 years, with a sex ratio of 1.7. The etiologies are dominated by accidents on public roads (58%). They show neurological disorders such as spinal cord damage in 30% of cases and root damage in 20% of cases. The radiological assessment revealed eight tear drops, ten comminuted fractures, 12 severe sprains, 12 biarticular dislocations, six uniarticular dislocations, and two herniated discs. Treatment was surgical in all patients with an anterolateral approach and anterior arthrodesis. The evolution was favourable in 21 patients and stationary in 29 patients. CONCLUSION: Our study concluded that dislocations and fracture dislocations were the predominant type of injury in cases of AVP. Tetraplegia was mainly observed with uni- and biarticular dislocations. The variation in consolidation time was not correlated with trauma-to-surgery time. Better neurological recovery was observed with mild initial neurological damage than with initially severe damage. The appearance of an adjacent syndrome is less frequent with monosegmental arthrodesis than with multisegmental arthrodesis. Cage arthrodesis was an alternative to iliac harvesting with similar results.
