[Trabecular connectivity in primary hyperparathyroidism].

By bone histomorphometry, 10 cases of primary hyperparathyroidism (PHPT) were used to study the trabecular connectivity, which in a few literatures was mentioned to be reserved somehow. Our data suggest that in comparison with the normal control (10 subjects) the nodes (N.Nd), the number of terminus (N.Tm), the total strut length (TSL), the length between the nodes (Nd.Nd), trabecular separation (Tb.Sp) and trabecular thickness (Tb.Th) were significantly increased while no significance was found in N.Nd/N.Tm, Tm.Tm and TBV. The correlation analyses indicate that there is no correlation between the variables in the normal controls. In contrast, however, TBV and Tb.Th showed negative correlations with N.Tm and Tm.Tm. Besides these, there were positive correlations between N.Nd/N.Tm and TBV or Tb.Th, and a negative correlation between N.Nd/N.Tm and Tb.Sp. The results suggest that to certain degree the trabecular connectivity in PHPT be destructed while the three dimensional architecture be reserved. Our data seem to be different from those reported previously. It may be due to the severity of PHPT in our patients.
