G. Demircin et al., MICROFOCAL RADIOGRAPHY IN THE DIAGNOSIS OF CHILDHOOD RENAL OSTEODYSTROPHY, Acta Paediatrica Japonica Overseas Edition, 40(5), 1998, pp. 461-465
Background: Renal osteodystrophy is common in children with chronic re
nal failure (CRF) and X-ray is an intensive method in the diagnosis of
the disease. In this study we compared microfocal radiography with co
nventional method for the diagnosis of renal osteodystrophy. Methods.
The X-rays of left wrists of 21 children with CRF and chronic renal in
sufficiency were taken by conventional and microfocal methods. Results
: Both methods revealed osteopenia in all patients (100%), widening, f
raying and cupping of ulnar and radial metaphysis in 10 (47.6%), osteo
sclerosis in three (14.2%) and pseudofracture in one (4.7%) patient. M
icrofocal radiography demonstrated osteosclerosis in one patient, pseu
dofracture in four and subperiosteal resorption in five patients that
were not detected by conventional method. Conclusion: Two methods were
found to be significantly different in demonstrating the changes due
to rickets and hyperparathyroidism and it is concluded that microfocal
radiography may be preferred in the diagnosis of childhood renal oste
odystrophy.
