ABSTRACT
BACKGROUND:
Although the popularity of the direct anterior approach for total hip arthroplasty has increased, the femoral procedure in this approach is considered technically challenging, and one of the most frequent complications reported was periprosthetic femoral fractures. The present study aimed to identify factors for predicting the risk of periprosthetic femoral fractures after using stems with a cementless tapered-wedge design through the direct anterior approach.METHODS:
We retrospectively assessed the medical records of 686 patients (851 hips) who underwent primary total hip arthroplasty using a single stem with a cementless tapered-wedge design having a short or standard length option. The direct anterior approach on a standard operating table was used for all hips. Multivariate logistic regression analysis was performed to identify the independent predictors of intraoperative and early postoperative periprosthetic fractures.RESULTS:
Seventeen periprosthetic femoral fractures (2.0%) were observed, including 10 intraoperative (1.2%) and 7 postoperative (0.8%) fractures. The occurrence rate of fractures using short stems was significantly higher compared with that using standard stems. The multivariate logistic regression analysis revealed that only stem length was significantly associated with periprosthetic fractures.CONCLUSION:
Our results indicate that the stem design affects the risk of periprosthetic femoral fractures.Palabras clave
