The overall mortality rate in patients with total hip arthroplasty, with special reference to coxarthrosis
Insights
Total hip arthroplasty (THA) outcomes vary by patient demographics and indication. Elderly women with coxarthrosis showed decreased mortality post-THA, unlike men. Revision surgery impacted mortality differently between sexes.
Area of Science:
- Orthopedic surgery
- Epidemiology
- Geriatric medicine
Background:
- Total hip arthroplasty (THA) is a common procedure for hip conditions.
- Long-term mortality following THA requires further investigation, especially concerning patient subgroups and indications.
Purpose of the Study:
- To analyze the long-term mortality rates in patients undergoing total hip arthroplasty.
- To identify demographic and indication-specific differences in post-THA mortality.
Main Methods:
- Retrospective cohort study involving 1385 patients who underwent THA between 1968 and 1981.
- Mortality rates were compared between patient groups and the general population at risk.
- Analysis stratified by sex, age, indication (coxarthrosis, hip fracture complications, rheumatoid arthritis), and revision status.
Main Results:
- Elderly women (over 70) with coxarthrosis demonstrated a decreased mortality rate after the first postoperative year compared to the general population.
- Men over 70 undergoing revision surgery for coxarthrosis experienced an increased mortality rate post-first year.
- Patients of both sexes below 70, operated on for hip fracture or rheumatoid arthritis complications, showed elevated mortality rates after the first postoperative year.
Conclusions:
- Post-THA mortality risk is influenced by sex, age, and the primary indication for surgery.
- Revision surgery in elderly men with coxarthrosis may be associated with increased long-term mortality.
- Urgent THA for complications like hip fracture or rheumatoid arthritis carries a higher long-term mortality risk across both sexes below 70.
Abstract:
The mortality rate was calculated in 1385 patients with total hip arthroplasties compared with the population at risk in the period from 1968 to 1981. In elderly women with coxarthrosis, after the age of 70, the mortality rate decreased after the first postoperative year. There was no such effect in men. In women, there were no changes in mortality rate in those who had had revision operations, whereas in men operated on for coxarthrosis who were over the age of 70, there was an increased mortality rate after the first postoperative year following revision. Patients operated on for complications after hip fracture and/or rheumatoid arthritis had an increased mortality rate after the first postoperative year, including both women and men below age 70.
