Pathologic femoral neck fracture due to renal osteodystrophy is rare. We report the case of a young adult patient with chronic renal failure who presented with bilateral spontaneous femoral neck fractures due to renal osteodystrophy. The pathophysiology of renal osteodystrophy and the treatment of hip fractures in patients with renal failure is discussed.

Figure 2 Bone Fibrous osteodystrophy in a male F344/N rat from a chronic study (same animal as in Figure 1). There is replacement of cortical bone by fibrous connective tissue.

Renal osteodystrophy is a common finding in patients with renal insufficiency. The maximum of its intensity is found in hemodialysis patients. Bone densitometry is so far the best method for non-invasive assessment of the extent of the illness. Some densitometric studies in hemodialysis patients have already been published but their results differ in prevalence and intensity of renal osteodystr...

Primary hyperparathyroidism associated with Albright's hereditary osteodystrophy was diagnosed in a 22 year old Japanese woman, the second such case to be reported. Albright's hereditary osteodystrophy (AHO) appears to be associated with a larger number of disorders than the well recognized pseudohypoparathyroidism. AHO and pseudo-pseudohypoparathyroidism are essentially identical.

Thinning of parietal bone bilaterally is extremely rare but well known phenomenon. Approximate prevalence is 0.4-0.5% according to radiological scans, case reports and anthropologic researches. Even though biparietal osteodystrophy occurs mostly in over 60-year-old women, it shows no special association with race or geographical area tendency. Current definition was changed by understanding tha...

Renal osteodystrophy is characterized by abnormalities in bone turnover, mineralization, and bone volume. The effects of treatment modalities for renal osteodystrophy on bone should be analyzed with respect to these abnormalities. The major treatment modalities for renal osteodystrophy include phosphate binders, vitamin D compounds, and calcimimetics. Aluminum-containing phosphate binders have ...
