2012 ANNUAL REPORT
There have been 14,901 total resurfacing procedures reported to the Registry,
an additional 603 procedures, compared to the last report.
The use of resurfacing hip replacement in Australia continues to decline. The
number of procedures reported in 2011 was 39.7% less than in 2010 and 68.5% less
compared to the peak in 2005.
Osteoarthritis is the principal diagnosis for total resurfacing hip
replacement (95.0%), followed by developmental dysplasia (2.5%) and
Most patients are male and the proportion of males has increased from 71.2%
in 2003 to 94.3% in 2011
There continues to be a shift in the use of primary total resurfacing hip
replacement to younger patients. The proportion of patients under the age of 55
years has continued to increase and accounted for 62.6% of all primary total
resurfacing procedures in 2011. There has been a corresponding decrease in use
for patients aged 55-64 years (Figure HT34).
The majority of total resurfacings use hybrid fixation (98.3% in 2011).
The BHR remains the most used resurfacing hip prosthesis in 2011. Although
its use has declined in absolute numbers in 2011 the proportion of resurfacing
procedures using BHR has increased from 62.6% in 2010 to 75.4% in 2011 (Table
The BHR resurfacing prosthesis has a cumulative percent revision at 11 years
Note about Total Hp Replacement Information:
At 11 years, hybrid fixation has the lowest cumulative percent revision of
6.0% compared to cemented (7.2%) and cementless fixation (7.8%) (Information
