Summary
Bone disease in chronic kidney disease is complex, evolving from vitamin D deficiency to complications like metastatic calcification and new issues in long-term dialysis patients. Radiographs are key, with other imaging aiding diagnosis.
Area of Science:
- Nephrology
- Orthopedics
- Radiology
Background:
- Bone disease in chronic renal impairment is complex and multifactorial.
- Historically dominated by vitamin D deficiency and secondary hyperparathyroidism.
- Modern management has shifted the prevalence of radiographic features.
Purpose of the Study:
- To describe the evolution and current spectrum of bone disease in chronic kidney disease.
- To highlight emerging complications associated with advanced renal disease management.
- To emphasize the role of imaging in diagnosis and management.
Main Methods:
- Review of radiographic features over decades.
- Analysis of complications related to phosphate retention and binders.
- Inclusion of newer complications in long-term hemodialysis and transplant patients.
Main Results:
- Radiographic features of vitamin D deficiency and secondary hyperparathyroidism are now less common.
- Metastatic calcification and "adynamic" bone are significant complications.
- Amyloid deposition, spondyloarthropathy, and osteonecrosis are emerging issues.
Conclusions:
- The landscape of renal bone disease has significantly changed.
- Newer complications require recognition in patients undergoing long-term renal replacement therapy.
- Radiography remains crucial, supplemented by advanced imaging techniques for diagnosis and management.
