Bone Quality in Chronic Kidney Disease: Definitions and Diagnostics

Area of Science:

• Nephrology
• Orthopedics
• Bone Biology

Background:

• Chronic kidney disease (CKD) is linked to impaired bone quality and increased fracture incidence.
• Bone quality encompasses microarchitecture, mineralization, turnover, and collagen structure.

Purpose of the Study:

• To review the epidemiology, diagnosis, and pathogenesis of fractures and renal osteodystrophy.
• To elucidate the role of bone quality in fracture susceptibility in CKD.
• To discuss emerging data on CKD's effects on bone quality and potential protective strategies.

Main Methods:

• Literature review of epidemiology, diagnosis, and pathogenesis.
• Analysis of recent data on CKD-related bone alterations.
• Evaluation of non-invasive methods for assessing bone quality.

Main Results:

• CKD is associated with abnormal bone quality and strength, resulting in high fracture rates.
• Emerging data highlights the impact of collagen structure on bone strength in CKD.
• Non-invasive methods show potential for informing bone quality assessment and fracture prevention.

Conclusions:

• Further prospective studies are needed to fully understand CKD's impact on bone.
• Altered bone quality in CKD necessitates targeted strategies to mitigate fracture risk.
• Improved understanding of bone quality can guide interventions to protect against bone loss and fractures.
