Objection: We compared T-scores of each femoral neck and trochanteric area in the neck fracture patients (NFP) and intertrochanteric fracture patients (IFP). Our hypothesis is that T-score of neck portion in NFP is lower than T-score of neck portion in IFP, and vice versa. We evaluate how FRAX probability is meaningful and sensitive in hip fracture patients.

Meterials and methods: From April, 2003 to September, 2012, 180 hip fracture patients (98 for NFP group, 82 for IFP group were included, and all patient was evaluated BMD within 2 weeks after trauma. we calculated FRAX probability in each patients. We evaluated the correlation between localized femoral BMD T-scores and fractures site of hip. We checked how many patients were included in high risk group by FRAX, defined as 10-year major osteoporotic fracture (MOF) probability (≥20%) or hip fracture probability (≥3%). Our study was approved by IRB.

Results: In NFP, average of T-scores in neck portion (−3.23) was lower than IFP (−2.93, P=0.029). In IFP, average of trochanteric T-score (−2.56) was lower than NFP (−2.54, P=0.95). Average of total femoral T-scores in NFP (−2.92) was lower than IFP (−2.75, P=0.28). FRAX probability of MOF in NFP (14.4%) was higher than in IFP (11.1%, P=0.009). FRAX probability of hip fracture in NFP (8.6%) was higher than IFP (5.9%, P=0.008). 19.5% of NFP and 10.1% of IFP were classified as high risk group for MOF. 77.3% of NFP and 80.8% of IFP were classified as high risk group for hip fracture.

Conclusion: Localized femoral T-scores were valuable predictive factor for hip fracture in osteoporotic patients. FRAX probability is meaningful and sensitive tool to evaluate the hip fracture in osteoporotic patients.
