The results of fifty-five cementless total hip arthroplasties using the Omniflex system were reviewed. All patients were followed clinically and radiographically for more than four years.
The AD stem (non-HA stem) was used from January 1993 to October 1995, and the Securflex (HA stem) was used from November 1995 to December 1996.
On the stem side, five unstable fixation stems were observed in the non-HA group. In the HA group, we found early osseointegration in all cases. On the socket side, there were no loose shells.
We need to observe osteolysis carefully since the onset of osteolysis seems to increase gradually with polyethylene wear.
