BACKGROUND The novel coronarvirus disease (COVID-19) has had a major impact on provision of spinal neurosurgery across the world, especially in the UK, with a significant fall in operating and patient volumes, and elective clinical activities. It is unclear whether the pandemic has affected the volume of urgent spinal procedures in the UK, especially surgical decompressions for cauda equina syndrome (CES). METHODS Therefore, we conducted a retrospective analysis of theatre records and electronic operation notes at our institution to identify all procedures performed for CES before (December 2019 to February 2020) and during (March 2020 to May 2020) the COVID-19 pandemic. Statistical analyses were performed on SPSS v22 (IBM). RESULTS Forty-four patients underwent surgical decompressions during the study period. Over half (54.5%) were female and the median age was 45 years (range = 22-78 years). Three in four procedures were performed at L4-5 and L5-S1 levels (79.5%). There was no statistically significant difference in the number of decompressions performed each month [χ2(5)=1.818; p = 0.874]. On the other hand, the number of referrals for suspected or confirmed CES fell by 81.8% between December 2019 and April 2020. CONCLUSIONS Our results did not show any statistically significant decline in the volume of surgical decompressions performed for CES despite the considerable fall in electronic referrals for CES and degenerative spinal conditions. This suggests that patients with critical neurological symptoms continued to present and were treated appropriately despite the restrictions imposed on spinal surgeons during the pandemic.
