Abstract
Purpose
The purpose of this study is to evaluate the clinical outcomes and and radiological findings of primary total hip arthroplasty(THA) performed by using cemented polished femoral stem.
Materials and Methods
We retrospectively reviewed 91 hips (84 patients) that had undergone primary THA with cemented polished femoral stem after follow-up more than 10 years. The mean age at surgery was 57 years old (47 to 75). Mean follow up period was 12. 8 years(10.1 to 14). Clinical evaluation was performed using Harris hip score. The radiographic evaluation was performed in terms of the cementing technique, including of subsidence within the cement mantle, radiolucent lines at the cement-bone or cement-stem interface, cortical hypertrophy, and calcar resorption.
Results
At the final follow-up, mean Harris hip score had improved from 55.2 points to 93.2 points. Barrack classification was 50 cases in A grade, 32 cases in B grade, 9 cases in C grade. Except only one case, subsidence of femoral stem was observed less than 2mm. There were no progressing radiolucent line and loosening of femoral stem.
Conclusion
Our results in this study show good outcome for cemented polished femoral stem at follow-up more than 10 years.
