Abstract
Purpose: To establish frequency of revision operations in the group of Lubinus implants.
To compare our results with results in Sweden.
To develop further activities in the improvement of the results.
Materials and Methods: Lubinus Classic Plus and Lubinus SP-2 implants were used.
From 1994 till 2004, 1,487 operations with Lubinus primary cemented implant were performed.
We registered the following parameters: number of revision operations per year and cause of revision operation – septic or aseptic.
Results: 29 revision operations were performed (1.95% of all THR with Lubinus implant).
14 revisions (0.94%) were performed because of septic complications and 15 revisions because of aseptic complications.
It was established that causes of aseptic complications were the following:
-
Loosening of both components – 6 cases
-
Loosening of acetabular component – 4 cases
-
Loosening of femoral component – 2 cases
-
Periprosthetic fractures – 2 cases
-
Tearing down of head of femoral component – 1 case.
We compared the number of revision operations of all THR with Lubinus implant because of aseptic and septic complications in Latvia and Sweden.
Because of aseptic complications in Latvia were 1.01% revision operations of all primary THR, but in Sweden – ~2–3% of all primary THR. Because of septic complications in Latvia were 0.94% revision operations of all primary THR, but in Sweden – 0.4% of all primary THR.
Conclusions: In Latvia primary THR with Lubinus implant have stable prognostic results and small number of revision operations. Therefore, the special regard should be paid to the prophylaxis of septic complications.
