Introduction:
The extended proximal femoral osteotomy (EPFO) is a demanding but useful technique for revision of both cemented or noncemented femoral components.
Materials And Methods:
Between 2000 and 2004 we performed extended proximal femoral osteotomy (EPFO) in 25 cases during revision hip surgery. The main indication for doing revision surgery was aseptic loosening of both total hip arthroplasty (THA) components (18 patients), whilst in the remaining 7 patients the indications were: aseptic loosening of acetabular component in three patients, septic loosening of THA in two patients, recurrent dislocation of the THA because of incorrectly positioned femoral component in one patient and aseptic loosening of cemented hip hemiarthroplasty in one patient.
Results:
There were 14 women and 11 men. The mean follow-up was 22 months. The average time to revision was 8.3 years. The mean age at the time of revision was 70.3 years (range 55 to 81). At the time of the last control examination all osteotomy sites had healed with signs of remodelling. The mean time to union ranged from 11 weeks to 6 months, shown by the bridging callous formation in both radiographic projections. Bone remodelling occurred in all patients by 12 months and no complications such as nonunion, excessive fragment migration or wire breakage were found.
Conclusion:
In our experience, the extended proximal femoral osteotomy when properly indicated represents an efficient and reliable technique in revision hip surgery.
