Non-traumatic spinal cord injury - etiological profile and associated factors: single rheumatological center experience.

Introduction: Non-traumatic spinal cord injury (NTSCI) represents a medical-surgical emergency. In Burkina Faso, limited data exist on the etiological profiles of this syndrome in rheumatology. This study aimed to describe the etiological profile of NTSCI in the Rheumatology Department of the University Hospital Center of Bogodogo (CHU-B).

Material and methods: This was a cross-sectional, retrospective study with descriptive and analytical aims, conducted from March 1, 2017, to December 31, 2023, in the Rheumatology Department of CHU-B. Patients diagnosed with non-traumatic spinal cord compression syndrome during hospitalization were included.

Results: The frequency in the Rheumatology Department of NTSCI was 2.94%, accounting for 104 patients. There were 68 men (65.38%), with a sex ratio of 1.88. The average age of the population was 57.91 years. All patients experienced back pain, with a lumbar location in 77 patients (74.04%). The average duration of the motor deficit was 2.97 months. A total of 3,532 patients were admitted to the conventional hospitalization unit of the Rheumatology Department at the CHU-B from March 1, 2017, to December 31, 2023. Among these, 104 patients had NTSCI, yielding a frequency of 2.94%. Spinal MRI was performed in 58 patients (55.77%), and the compression was extradural in 76.92% of cases (n = 80). The etiologies identified were Pott's disease in 32 patients (30.77%), followed by spinal metastases in 22 patients (21.15%). Twenty-nine patients (27.89%) experienced complications related to prolonged bed rest. No factor was significantly associated with the recovery of the motor deficit.

Conclusions: Non-traumatic spinal cord injury is relatively rare in rheumatological practice in Ouagadougou. The etiology is predominantly Pott's disease, which confirms the geographical distribution of NTSCI causes.
