In order to study the role of calcium-regulating hormones during callus formation in elderly patients, serum levels of parathormone (PTH), calcitonin (CT), 25-hydroxyvitamin D [25-OH-D], 1,25-dihydroxyvitamin D [1,25(OH)2D], 24,25-dihydroxyvitamin D [24,25(OH)2D], and calcium (Ca) were determined in 41 patients with fractures of long bones, primarily hip fractures. The parameters were measured on admission and after eight weeks. There were almost no changes in hormone serum levels during bone repair, except for a decrease in serum levels of 1,25(OH)2D from 25.3 +/- 2.3 pg/ml on admission to 21.0 +/- 2.0 pg/ml eight weeks later (p less than .001). Patients with fractures compared to normal elderly humans have lower serum levels of PTH (0.99 +/- 0.06 ng/ml versus 1.88 +/- 0.34 ng/ml; p less than .001), 25-OH-D (10.7 +/- 1.0 ng/ml versus 17.1 +/- 1.8 ng/ml; p less than .001), and Ca (9.1 +/- 0.1 mg% versus 9.7 +/- 0.1 mg%; p less than .001) and higher serum levels of 1,25(OH)2D (25.3 +/- 2.3 pg/ml versus 17.1 +/- 2.3 pg/ml; p less than .001). Female patients have lower serum levels of 24,25(OH)2D compared to males (1.65 +/- 0.15 ng/ml versus 2.06 +/- 0.29 ng/ml; p less than .05). A similar trend was noted in serum CT levels during callus formation (0.12 +/- 0.02 ng/ml versus 0.16 +/- 0.02 ng/ml; p less than .05). Patients with subcapital fractures of the femur have significantly lower serum levels of all vitamin D metabolites on admission, compared with patients suffering from extracapsular fractures.(ABSTRACT TRUNCATED AT 250 WORDS)
