The purposes of this study were (1) to compare the results between the Engh score to assess osseointegration and stability of the cementless stem with results of a score called the O-SS score (osseointegration-secondary stability), which takes into account the radiolucent line, (2) to verify the relationship between these two scores and the functional results, and (3) to verify if there is a relationship between the O-SS score and secondary subsidence or a pedestal. A clinical and radiological evaluation was performed in a group of 100 hip prosthesis revisions comparing the results obtained by Engh score and O-SS score for which reproducibility was analysed. Inter-observer reproducibility was estimated to be average at 0.5 and intra-observer reproducibility good at 0.7. The correlation with the Engh score was good at r = 0.59 (p < 0.0001). For the 80 cases assessed O-SS score as very good/good, Harris hip score was at 83.7 versus 78.25 for the 20 cases assessed as average/poor (p = 0.07). For the 73 cases with assessed Engh score as very good/good, this score was at 82.8 versus 82.14 for the 27 cases assessed as average/poor. No correlation between the O-SS score and secondary subsidence (p = 0.2) or pedestal (p = 0.2) was noticed. The evaluation of the clear radiolucent line alone, extent and location, is a sufficient condition to assess osseointegration and secondary stability of a cementless femoral stem.Show less >
