Hypothesis
This study aims to report national data on hip replacements, incidence rates, demographic characteristics of patients, and short-term survival rates after hip replacement in Taiwan.
Conclusion
Avascular necrosis is the main disease leading to total hip replacement in Taiwan, and the incidence of hip replacements has significantly increased from 1996 to 2004.
Supporting Evidence
- The average annual number of primary partial hip replacements was 4,257 and for total hip replacements was 6,206.
- The cumulative survival rate for primary partial hip replacements was 93.97% and for total hip replacements was 79.47% over 9 years.
- The incidence rate for males was slightly higher than for females, with 23 per 100,000 for males and 20 per 100,000 for females.
Takeaway
This study looked at how many people in Taiwan got hip replacements and found that a lot more people are getting them now than before, especially for a condition called avascular necrosis.
Methodology
The study analyzed 105,688 cases of hip replacements from the National Health Insurance research database between 1996 and 2004, using the Kaplan-Meier method to estimate survival rates.
Limitations
The study did not record information on the replacement side, implant type and size, surgical approach, and cement brand, which are important factors influencing survival rates.
Participant Demographics
The mean age of patients was 64 years, with 49% being men.
