ABSOLUTE FRACTURE RISK ASSESSMENT IN OUTPATIENTS WITH DISTAL RADIUS OSTEOPOROSIS
Osteoporoz i osteopatii
Objectives: to assess the absolute fracture risk in outpatients with osteoporosis (OP) at distant radius. Methods: individual absolute fracture risk was assessed using FRAX tool without hip neck bone mineral density (BMD) input in 3082 subsequent subjects (2911 females and 171 males) aged from 40 to 95 (median age 60), calculated by Finnish population data. Distant radius BMD was estimated in all patients by DTX200. Results: 774 (25.1 %) patients had had history of low traumatic fractures.
... tic fractures. BMD≤- .5 SD was detected in 1659 cases, fracture history in 558 (33.6%) of them (OR = 2.21; 95 % CI 1.93-2.55). Median 10-year probability of a major osteoporotic fracture was 4.90 % (25- 75 %; 1.10 - 55.0) and 10-year probability of a hip fracture was 0.8 % (0 - 46), absolute risk 10 % and higher was detected in 434 (64,3 %) patients. Calculated 10-year probability of a major osteoporotic fracture > 10 % was associated with previous low traumatic fractures: OR = 4,55; 95 % CI 4,06- 5,10, test sensitivity being 56.1 % with specificity 89.6 % . The same association was found for 10-year probability of hip fracture >3 %: OR = 3.57 (3.19 - 4.00), test sensitivity being 51,6 % with specificity 86,7 %. Conclusion: FRAX tool for individual absolute fracture risk assessment should be introduced into general practice for clinical decision making in prophylaxis of OP associated fractures.
