DXA-based bone strain index in normocalcemic primary hyperparathyroidism.The trabecular and cortical bone assessed by bone strain index seems not to be significantly affected in NHPT.


 The bone strain index (BSI) is a deformation index based on the finite element method and can be applied to DXA scans.

A case-control study included 170 subjects: 40 subjects with NHPT, 50 subjects with primary hypercalcemic hyperparathyroidism (PHPT), and 80 controls (age- and sex-matched with the NPTH group).
