| Research Abstract |
1.Risk factors for osteoporosis related fractures
We conducted a case-control study to elucidate risk factors for fractures of distal radius and proximal humerus. We found greater frequency of going outside and better ability of long gait were significant risk factors, and futon use (instead of bed use) was a protective factor for distal radius fractures. On the other hand, greater frequency of going outside significantly decreased the risk of proximal humerus fractures. Falling tendency was a significant risk factor for both fractures.
2.Sequential QOL changes in patients with osteoporosis related fractures
We evaluated quality of life (QOL) in 115 patients 45 year-old and over (mean:73.5 year-old) with osteoporosis related fractures. Out of the 115 patients, 35 were vertebral fractures (VF) (all treated conservatively), 35 were hip fractures(HF)(all treated surgically), and 45 were distal radius fractures (RF) (20 treated conservatively, 25 treated surgically). QOL was evaluated using EuroQol (EQ-5D). Mean health related QOL scores in VF were 0.89,0.50,0.75, and 0.74, before, just after, 3 months after, and 6 months after the fracture, respectively, and did not recover until 12 months after the fracture. In HF, they were 0.74,0.39,0.60, and 0.60, respectively, and did not recover until 12 months after the fracture. In RF, they were 0.91,0.70,0.83, and 0.80, respectively, and recovered 12 months after the fracture.
3.Treatment cost of osteoporosis related fractures
Among the subjects we evaluated QOL, we investigated the treatment cost of the fractures in hospitals which allowed this survey. As a result, the costs in hospital were 480 thousand yen in VF, 1,736 thousand yen in HF, and 98 thousand yen in RF.
