Objective: Difficulty in accessing osteoporosis treatment during the Covid-19 pandemic period, social isolation, immobilization, steroids used and the inflammatory effects of Covid-19 may contribute to the development of osteoporosis. Therefore, in this study, we aimed to evaluate with quantitative data whether patients with Covid-19 infection pose a risk for the development of osteoporosis.

Material and Method: The study is single-centered. Patients whose Covid-19 infection were retrospectively screened. Bone mineral density measurements were performed before and after Covid-19 infection and female patients over the age of 18 were included in the study. A total of 55 patients were examined. The patients\' age, medications used during the Covid-19 treatment process and the number of days spent in the service and/or intensive care unit (ICU) were recorded. Lumbar total T score, femoral neck T score and femur total T scores detected.

Results: A significant relationship was found between the patients ICU stay and the femoral neck T score (p <0.05). As the length of stay of the patients in the ICU increased, a decrease in the femoral neck T score was detected. No significant relationship was detected in other parameters evaluated.

Conclusion: It was found that as the length of stay in the ICU of patients with Covid-19 increased, the femoral neck T score decreased. Keeping ICU stays as short as possible in patients infected with Covid-19 may be beneficial to reduce hip osteoporosis.
