Assessment of Results of Total Hip Replacement Using SFEN Implants (preliminary report)
From January 1999 to August 2004 total hip replacement with cement SFEN-C implants was performed in 113 patients (128 joints). Average age of patients at surgery was 65.5 years (from 21 to 87). Results were evaluated 3, 6, 12 months after operation and then yearly. At control examination pelvic radiography, assessment of cement technique by Barrack, dynamics of radiographic density at the metal-cement borders, cement-bone of femoral component by Gruen as well as acetabular component by DeLee and Charnley were performed. Functional result was evaluated by Merle d'Aubigne and Postel systems in modification by Charnley and by Harris. Mean follow-up was 20.3+10.8 months (from 3 to 68 months). Long-term results were studied in 87 patients. No sings of polyethylene shell wear and acetabular and proximal femur osteolysis were detected. No clinical symptoms of instability requiring re-operation were noted.
