Femoral fractures

Summary

Evidence from six studies suggests that poorer bone quality, lower canal flare index scores, fracture as the indication for the index operation, and initial prosthesis type may increase the risk implant-related fracture. There is conflicting evidence regarding age as a risk factor and sex was not a significant independent risk factor even though more females tended to have such fractures.

Given the infrequent nature of implant-related fracture, additional rigorous, multicenter and/or registry-based prognostic factor studies, which adjust for potentially confounding factors, are necessary to more carefully examine risk factors for such fractures after hip surgery.
