Figures & data
Table 1. Age and sex-specific incidence rates from 1995–2006, of primary total hip arthroplasties per 100,000 inhabitants
Table 2. Characteristics of the total hip arthroplasty patients and operations registered in the NARA database, 1995–2006
Table 3. The 10 most commonly used total hip prostheses (combination of cup/stem) in each country, according to brand and type of fixation
Figure 1. Kaplan-Meier estimated curves until revision for any cause, for primary total hip replacements (THAs) in Denmark, Sweden, and Norway 1995–2006. Curves are given for all THAs and also for those classified according to fixation technique as cemented, uncemented, and hybrids (uncemented cup/cemented stem).
Table 4. Cox regression estimates of survival probabilities and relative risk of any revision (RR) with 95% confidence intervals (CIs) for all THAs and according to fixation technique with adjustment for sex, age, and diagnosis, and comparing the three countries. Subanalyses on patients younger and older than 60 years of age are presented
Figure 2. Kaplan-Meier estimated curves until revision for any cause, for primary cemented and uncemented total hip replacements (THRs) in Denmark, Sweden, and Norway 1995–2006, in patients younger than 60 years and in those aged 60 and older.
Table 5. Cox regression estimates of survival, and relative risk of any revision (RR) with 95% confidence intervals (CIs), according to time-dependent covariates (follow-up < 5 years or ≥ 5 years for uncemented THAs, and follow-up < 7 years or ≥ 7 years for hybrids), for all age groups and for patients less than 60 years of age
