Percutaneous bone biopsy in the diagnosis of renal osteodystrophy

Renal failure is associated with many complex bone and mineral complications. The spectrum of diseases is wide, encompassing defects in bone turnover, remodeling, and mineralization. Disease is currently defined in terms of whether a high or low turnover lesion is present. Measurement of serum parathyroid hormone levels (PTH) remains an important aspect in the management of renal bone disease, however, is limited by its lack of sensitivity in many clinical settings. Multiple biochemical markers are also available both commercially and experimentally to assist in assessing the degree of bone formation or resorption. However, when definitive diagnosis is important, when the clinical setting is confusing or complex, or when parathyroidectomy is being considered, the use of percutaneous bone biopsy is an essential tool in the understanding of underlying bone pathology and in directing therapy intervention.
