In osteoporosis, sarcopenia is a common condition. Sarcopenic measurements can be made by evaluating muscle thickness in different regions. We aim to evaluate lumbar muscle losses in patients with osteoporosis in the lumbar region and to examine whether these muscle losses are correlated with the level of osteoporosis. The patients will be divided into 3 groups as healthy, osteopenic and osteoporotic according to DEXA measurements. Demographic values, comorbidities, osteoporosis drugs used, fracture histories, L1-4, L2-4, femoral neck and total BMD and t values of the patients, psoas and multifidus muscle measurements will be made at L2-L3 level in Lumbar MR imaging. Lumbar MR muscle measurements will be made by 1 physician blind to the DEXA values of the patients.

Inclusion Criteria:

• 50-90 years old
• 2. Recent MRI of the lumbar region with DEXA evaluation

Exclusion Criteria:

• Have had previous lumbar surgery
• Any previous lumbar injection
• Stage 3-4 Lumbar Listesis
• Presence of Lumbar Discopathy accompanied by neurological deficit

50-90 years old osteoporotic, osteopenic and healthy people
