Renal osteodystrophy in end-stage renal failure

D F Nortman, J W Coburn

    Postgraduate Medicine
    |November 1, 1978
    PubMed
    Summary

    Renal osteodystrophy, a bone disease in kidney failure, presents with fractures and cysts due to secondary hyperparathyroidism. Managing phosphate and calcium levels is key to preventing and treating this condition.

    Area of Science:

    • Nephrology
    • Endocrinology
    • Radiology

    Background:

    • Renal osteodystrophy encompasses diverse skeletal pathologies like osteitis fibrosa, osteomalacia, and osteopenia.
    • Secondary hyperparathyroidism, common in renal failure, is a primary driver of these bone abnormalities.
    • Interrelated derangements in parathyroid hormone, calcium, phosphate, and vitamin D metabolism contribute to pathogenesis.

    Purpose of the Study:

    • To outline the skeletal manifestations of renal osteodystrophy.
    • To highlight the role of secondary hyperparathyroidism in its development.
    • To emphasize diagnostic approaches and management strategies.

    Main Methods:

    • Review of skeletal pathologic features associated with renal failure.
    • Analysis of the pathogenetic roles of hormonal and metabolic derangements.
    • Discussion of radiological findings and their variability.
    • Emphasis on diagnostic utility of hand X-rays for subperiosteal resorption.

    Main Results:

    • Renal osteodystrophy presents with fibroosteoclasia, osteomalacia, osteopenia, pseudofractures, cysts, and osteosclerosis.
    • Secondary hyperparathyroidism is a major cause of these skeletal changes.
    • Radiological findings vary based on patient age, dialysis duration, and imaging techniques.

    Conclusions:

    • Effective prevention and management of renal osteodystrophy depend on controlling hyperphosphatemia and hypocalcemia.
    • Hand X-rays are valuable for detecting subperiosteal resorption in dialysis patients.
    • Understanding the interplay of hormonal and metabolic factors is crucial for addressing renal osteodystrophy.
