RISK OF HIP FRACTURE AFTER OSTEOPOROSIS FRACTURES - 451 WOMEN WITH FRACTURE OF LUMBAR SPINE, OLECRANON, KNEE OR ANKLE

In a follow-up study during 1976-1984, the risk of a subsequent hip fr acture was investigated in women aged 60-99 years, hospitalized for th e following fractures: lumbar spine (n 70), olecranon (n 52), knee (n 129) and ankle (n 200). Follow-up ranged from 0 to 9 years. Observatio n time of the 4 different fractures were 241, 180, 469, and 779, perso n-years, respectively. In women aged 60-79 years with one of the follo wing fractures the relative risk of a subsequent hip fracture was incr eased by 4.8 (lumbar spine), 4.1 (olecranon), 3.5 (knee) and 1.5 (ankl e). The relative risk of hip fracture showed a tendency to level off 3 years after the primary fracture.
