Objectives: Interest of this study is to report four cases of spinal cord injuries without bone lesion. Evolution of the injured patients according to the initial clinic assessment at admission and the treatment performed are discussed. Materials and Methods: From January to December 2016, we performed a retrospective study at the Neurosurgery Department of Hospital General Grand Yoff of Dakar. Four patients were followed for spinal cord injury without visible bone lesions. We analyzed the clinical, radiological, therapeutic and evolutionary data. Trauma caused by stabbing was excluded. Results: In a year, 83 cases of spinal trauma with neurological deficit were hospitalized in the department. Among them, 4 had spinal cord injuries without visible bone lesions. The average age was 31.7 years with extremes ranging from 14 to 47 years. The sex ratio of male/female was 3. We have recorded 2 cases of road traffic accidents, 1 case of fall from height and 1 case of sports accident. On the neurological level, we found 3 cases of tetraplegia, and 1 brachial monoplegia. Computed tomography in all patients was normal. All of them benefited from magnetic resonance imaging that showed spinal cord injury. All patients were under conservative treatment. One patient fully recovered, two partially and one passed away. Conclusion: In presence of any post traumatic myelopathy case, the absence of disco-vertebral lesions should bring to mind the SCIWORA as well as indicate the realization of magnetic resonance imaging.
