Abstract:

BACKGROUND: Singh index and bone mineral density (BMD) are widely used in measuring bone strength and osteoporosis, however, the relationship between them, as well as difference in genders, are rare reported. 
OBJECTIVE: To analysis the relationship between BMD and Singh index in different genders.
METHODS: A total of 42 samples were collected from patients suffered femoral neck fracture and received operation of total hip replacement. The BMD of primary bearing area was measured by Dual Energy X-Ray Absorptiometry. All the patients had Singh index according to X-ray before operation. The relationship between BMD and Singh index were explored.
RESULTS AND CONCLUSION: The correlation index of Spearman in male about Singh index and BMD was r=0.646, P=0.002, which had a significant correlation. In particular, the BMD value was positive associate with Singh index, which could be used in judging the state of osteoporosis. The Spearman index of female about Singh index and BMD was r=0.304, P < 0.181. There was no dramatic correlation between them. It demonstrated that the relationship between Singh index and BMD was unclear for female postmenopausal osteoporosis, thus, clinical treatment should be selected individualized.
