Insertion of Primary Hip Prostheses

• There were just under 10,000 hip prosthesis procedures in 2024.
• The number of operations per 1,000 inhabitants has remained largely unchanged in recent years and is slightly above pre-pandemic levels.
• There is relatively little variation between the different catchment areas

In 2024, a total of 9,857 hip replacement procedures were carried out on patients aged 50 and over. This represents an increase of 7.5% from 2022. The explanation for this rise is likely partly due to the population growth within this age group. The number of residents in Norway aged 50 and over increased by 3.8% during the same period.

The number of procedures per year saw a significant decline during the pandemic. Following the pandemic, the number has risen to a level higher than before.

The number of operations per 1,000 inhabitants was 4.7 in 2024, with the rate remaining roughly the same as in the two previous years.

Women undergo surgery to a greater extent than men, with 65% of the operations in 2024 being performed on women. The average age of patients aged 50 and over who underwent surgery was roughly the same for both sexes in 2024, at around 70 years.

The analysis is based on activity data from the Norwegian Patient Register (NPR) for somatic specialist healthcare services. The data includes activities in public hospitals and private hospitals providing publicly funded services.

The selection includes contacts recorded with one or more of the procedure codes NFB20, NFB30, NFB40, or NFB99. Contacts containing diagnosis codes for hip fractures (S72.0, S72.1, and/or S72.2) are excluded.

The place of treatment is divided into three categories:

• Local public, treated at one of the hospitals in the catchment area
• Other public, treated at a public hospital outside the catchment area
• Private, treated by a private hospital

Insertion of hip prostheses is mainly performed on adult patients. Therefore, the population includes only patients aged 50 and older. Hip prosthesis procedures in individuals aged 0–49 accounted for just over 500 operations, or 5%, in 2024.

In order to compare the catchment areas and between years, the rates have been adjusted for gender and age. The adjustment was done using the direct method with the countrys population in 2023 as the reference population.
