Abstract
BACKGROUND

Some scholars believe that there is a certain correlation between coronavirus disease 2019 (COVID-19) infection and the occurrence of osteoporotic vertebral compression fractures (OVCF), but no relevant domestic research reports have been published yet. This study retrospectively analyzed the clinical data of patients admitted for OVCF and treated with percutaneous vertebroplasty during the normalized prevention and control period of COVID-19 in Shanghai (after June 1, 2022), aiming to explore the individual differences of OVCF patients during this special period and analyze the risk factors for OVCF.

AIM

To explore risk factors for senile OVCF during COVID-19 normalization.

METHODS

Retrospective analysis of 230 OVCF patients (June 2022 to June 2023, percutaneous vertebroplasty, observation group) and 236 controls (June 2020 to June 2021, OVCF surgery). Observation group was split into nucleic acid-positive (n = 85) and negative (n = 145) subgroups. Fracture location/cause, visual analogue scale, activity scores were compared; risk factors identified.

RESULTS

Observation group had 42.2% thoracic fractures and 38.2% cough-induced fractures (both higher than controls, P < 0.05). No significant differences in post-op visual analogue scale (1 day, 1 month) or activity scores (P > 0.05). Nucleic acid results, fracture cause/location correlated (P < 0.05; cause-location r = 0.827). Logistic regression showed fracture cause, nucleic acid result, body mass index, bone mineral density as high-risk factors.

CONCLUSION

During COVID-19 normalization, cough is the top OVCF cause; thoracic fractures rise. The four factors above are independent risks. For elderly COVID-positive patients with recurrent cough, lung disease treatment, anti-osteoporosis therapy, and thoracic braces prevent thoracic OVCF.

Keywords: COVID-19; Normalized prevention and control; Osteoporotic vertebral compression fracture; Risk factor; Cough

Core Tip: During the normalized prevention and control period of coronavirus disease 2019 (COVID-19), compared with cases in the same period, cough is the main cause of osteoporotic vertebral compression fracture (OVCF), and most fractures are thoracic fractures. After percutaneous vertebroplasty treatment, the improvement of pain and function in patients is not significantly different from that in the same period. Regression analysis shows that cause of fracture, nucleic acid test result, body mass index, and bone mineral density are independent risk factors for thoracic OVCF. For elderly COVID-19-positive patients with recurrent cough, timely and active treatment of lung diseases, aggressive anti-osteoporosis therapy, and wearing a thoracic brace for protection are effective measures to prevent thoracic OVCF.
