Lai YS, Wei HW, Cheng CK - J Orthop Surg Res (2008)

Bottom Line: There is no national joint replacement registry in the country of Asia and reports of national outcomes of joint replacement in Asia as yet.Both the number of primary partial hip replacements and primary total hip replacements increased steadily between 1996 and 2004.The cumulative survival of primary partial hip replacements and primary total hip replacements in all patients were 93.97% and 79.47% in 9 years follow-up, respectively.

ABSTRACT

Background: There is no national joint replacement registry in the country of Asia and reports of national outcomes of joint replacement in Asia as yet. Therefore, this study was then to report a national data of the number of hip replacements, incidence rate, demographic characteristics of hip replacement patients, and short-time survival rate after hip replacement of Han Chinese in Taiwan.

Methods: We analyzed 105,688 cases of hip replacements (including primary partial hip replacement, primary total hip replacement and revision of hip replacement) from National Health Insurance research database between 1996 and 2004. The survival rate of primary hip replacement was estimated for each disease by the Kaplan-Meier method.

Results: Average annual number of primary partial hip replacement and primary total hip replacement were 4,257 and 6,206 cases, respectively. The most two common diagnosis of primary partial hip replacement were femoral neck fractures (73.6%, 34% men, mean age 76 years) and avascular necrosis (18.0%, 84% men, mean age 48 years). In primary total hip replacements, the most two common diagnosis were avascular necrosis (46.9%, 79% men, mean age 50 years) and osteoarthrosis (41.6%, 43% men, mean age 60 years). Both the number of primary partial hip replacements and primary total hip replacements increased steadily between 1996 and 2004. The cumulative survival of primary partial hip replacements and primary total hip replacements in all patients were 93.97% and 79.47% in 9 years follow-up, respectively.

Conclusion: Avascular necrosis is the main disease in total hip replacement in Taiwan. The epidemiology of hip diseases was different between Han Chinese (in Taiwan) and Caucasian and the number of hip replacements increased substantially in Taiwan between 1996 and 2004.

Mentions: Average annual number of primary PHR and THR in Taiwan were 4,257 THRs, 6,206 PHRs, respectively. The incidence rate including primary PHR and THR for male (23 per 100,000) was slightly higher than female (20 per 100,000) per year. The mean age of the patients was 64 years old for the primary PHR and THR, and 49% of the patients were men. The incidence rate (including primary PHR and THR) was increased from 1996 (37 per 100,000) to 2004 (55 per 100,000). Both the trend of primary PHR and THR were increased as shown in Figure 1.
