Figure 7From: In vivo evaluation of a vibration analysis technique for the per-operative monitoring of the fixation of hip prosthesesCorrection of the femoral canal (non-typical case 3). a. FRF graphs corresponding to the insertion stages 7 and 8 (typically observed right shift). b. FRF graphs corresponding to the insertion stages 8 and 9 (anomalous left shift). c. FRF graphs corresponding to the two final stages (labelled 4a and 5a) of the reinsertion process, after the correction of the femoral canal.Back to article page
