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.
