Investigations into the causes of osteomalacia in 12 geriatric patients with a histologically proven diagnosis, revealed no predominant aetiology. The metabolic bone disease in these patients appeared to have multifactorial causes in at least half the cases.
In 30 elderly patients, the measurement of serum phosphate levels before and after intravenous vitamin D3 was not found to be a useful way of predicting the presence or absence of osteomalacia as determined by bone biopsy.

Using the combined results of oral and intravenous xylose tests, it is demonstrated that 26 percent of a group of geriatric patients absorb from the small bowel less efficiently than younger subjects. The method used excludes poor renal function and incomplete bladder emptying as possible causes for the differences found between the two age groups. Altered gastric emptying is also excluded as a possible factor.
