Abstract:

BACKGROUND: It is still a thorny problem faced by orthopedic surgeons how to select the right femoral prosthesis fixation in total hip revision in elderly patients at present. Application of revision surgery with modular femoral prosthesis can effectively deal with such problems.
OBJECTIVE: To evaluate the clinical outcomes of the application of un-cemented distal fixation stem in the total hip revision of elderly patients.
METHODS: Eleven patients aged over 75 years with aseptic loosening femoral stem were revised. According to Paprosky classification system, type Ⅰ was 2 cases, type Ⅱ was 2 cases, type ⅢA was 7 cases.
RESULTS AND CONCLUSION: All cases were followed up for over 16 months. The average Harris hip score increased from 37 to 89. The excellent or good rate post-surgery was above 90%. No loosening occurred again after revision. The radiographs after surgery showed increased bone density and thickness around the prosthesis. Reliable axial and anti-rotational stability can be achieved with the application of un-cemented distal fixation stem. It is especially appropriate for the revision surgery in elderly patients.
