Hip prosthesis のX線学的検討

Anatomic stem と Harris/Galante stem の比較検討

抄録

We studied femoral bone changes in 22 hips of 20 patients who had received an uncemented hip prosthesis. In 17 hips of 16 patients an anatomic hip prosthesis (A group) was used and in 5 hips of 4 patients the Harris/Galante hip prosthesis (H group) was used. The average age of A group was 65.6 years and that of H group was 68.8 years. The average follow-up period of A group was 2.7 years and that H group was 5.8 years.
No A gruop patients had thigh pain but 4 H group patients reported thigh pain.
The radiological findings of A group were stable; the fixation in the porous region was good. In H group there were 2 patients who had evidence of roentogenographical failure; subsidece and nonfixation in the porous region.
