Current use of codeine or propoxyphene in adults aged 65 or older was associated with an increased risk of hip fracture compared to nonusers (RR 1.6; 95% CI 1.4-1.9).

Does the use of codeine or propoxyphene increase the risk of hip fracture in elderly persons?
Current use of codeine or propoxyphene in elderly patients is associated with a significantly increased risk of hip fracture, particularly among new users and those concurrently taking psychotropic medications.
Relative Risk: 1.6 (95% CI 1.4–1.9)
We studied the risk of hip fracture in elderly persons receiving prescriptions for two commonly prescribed opioid analgesics--codeine and propoxyphene. Using automated prescription and hospitalization data, we identified 4,500 residents of Saskatchewan, Canada, aged 65 or older, who sustained a hip fracture between 1977 and 1985, and 24,041 age- and sex-matched controls. Compared to nonusers, the relative risk (95% CI) of hip fracture in current users of codeine or propoxyphene was 1.6 (1.4-1.9). There was no difference between relative risks of fracture among current users of codeine 1.6 (1.3-1.9) and propoxyphene 1.6 (1.2-2.2). In new users of these opioids, the relative risk of fracture was 2.2 (1.7-2.8), compared to 1.3 (1.0-1.6) in users who received at least one additional prescription for codeine or propoxyphene in the 90-day period prior to the index date. Concurrent users of these opioids and psychotropic drugs (sedatives, antidepressants, or antipsychotics) had a risk of fracture 2.6 (2.0-3.4) times that of nonusers of either drug class. Review of a sample of medical records for 701 cases suggested this finding was not due to confounding by body mass, ambulatory status, functional status, or dementia. Given the essential role of opioids in the management of pain in geriatric practice, further study is needed to determine the psychomotor effects of opioid analgesics in older adults.
Shorr et al. (Wed,) conducted a case-control in Hip fracture (n=28,541). Codeine or propoxyphene vs. Nonusers was evaluated on Hip fracture (RR 1.6, 95% CI 1.4-1.9). Current use of codeine or propoxyphene in adults aged 65 or older was associated with an increased risk of hip fracture compared to nonusers (RR 1.6; 95% CI 1.4-1.9).
