Neuropathic Pain During Common Lumboradiculalgia in Subsaharian Africa: Bicentric Study About 409 Patients.

Abstract

Background: Neuropathic pain is defined as pain caused by injury or disease of the somatosensory nervous system. Our purpose was to study the frequency of neuropathic pain among common lumboradiculalgia patients in subsaharian Africa patients. Methods: This was a bicentric cross-sectional study from February 2015 to 30 July 2015 in the first center and then from February 2017 to 30 July 2017 in the second center, i.e. a duration of 6 months for each study site. All patients with a common lomboradiculalgie were included. DN4 questionnaire was used for the diagnosis of neuropathic pain.Results : Four hundred and nine patients with common lumboradiculalgia were included. There were 278 females (67.97%) and 131 males (32.03%), for a sex ratio of 0.47. The average age was 51.75 ± 13.84 years with extremes of 16 and 88 years. One hundred and seventy-five patients ( 42.8%) had NP. Statistical analysis showed a statistically significant association between the existence of NP and age over 60 years and the existence of radiculalgia. Conclusions: Our study confirms the high frequency of neuropathic pain during common lumboradiculalgia. Age over 60 years and Poorly systematized radiculalgia were associated to NP.
