This study is a retrospective case-control study. In the study, the data of 304 patients who were evaluated in our clinic between January 2017 and January 2020 with a pre-diagnosis or diagnosis of postmenopausal osteoporosis were retrospectively reviewed. Lumbar 1-4 and femoral neck bone mineral densitometry values T scores, ages, sedimentation, C-reactive protein, neutrophil, leukocyte and platelet levels, and mean platelet volume values of the patients were recorded. The neutrophil-lymphocyte ratio was calculated by dividing the neutrophil count by the lymphocyte count, and the platelet-lymphocyte ratio was calculated by dividing the platelet count by the lymphocyte count. The systemic immune inflammation index (SII) was calculated using the formula, SII = platelet count x neutrophil count / lymphocyte count. The aim of this study is to evaluate the prognostic value of the systemic immune inflammation index in postmenopausal osteoporosis and to examine the SII, N / L, PLT / L, MPV, sedimentation (ESR), C reactive protein (CRP), femur and lumbar BMD values and their relationships with each other.

Inclusion Criteria:

• Having applied to our clinic with the diagnosis or pre-diagnosis of postmenopausal osteoporosis or osteoporosis with pathological fractures

Exclusion Criteria:

• Having a diagnosis of osteoporosis due to conditions other than postmenopausal osteoporosis
• Those with acute or chronic infection, malignancy and systemic diseases that may change the hematological inflammation parameters to be checked
• Persons who are missing one or more of the parameters planned to be considered among the obtained data

In the study, the data of 139 patients who were evaluated in our clinic between January 2017 and January 2020 with a pre-diagnosis or diagnosis of postmenopausal osteoporosis were retrospectively reviewed.
