Seven-year follow-up of total hip replacement with the Brunswik prosthesis.

One hundred and sixty-one non-infected total hip arthroplasties were reviewed on average 4 years post-operatively and 113 of these were reviewed again on average 7 years post-operatively. Non-infectious stem loosening was observed in 38% and required exchange operation in 20%. At review, 12 sockets (7%) were found to be loose. However, the mean hip scores were good, which could partly be explained by cases excluded because of revision.
