Association between creatinine clearance and lumbar bone mineral density in Chinese patients with osteoporotic fractures: a retrospective cross-sectional study

Key Points

• Lumbar bone mineral density is positively associated with creatinine clearance in elderly patients with osteoporotic fractures.
• A threshold of approximately 130 mL/min in creatinine clearance highlights a non-linear relationship with bone density.
• The observational cross-sectional study uses data from elderly Chinese patients, reinforcing the relevance of renal function evaluation.
• These findings suggest that assessing renal function can play a significant role in managing osteoporosis and fracture risks.
