“…Beals and Tower [1] reported the results of 93 periprosthetic fractures treated at numerous facilities by multiple surgeons. Overall, outcomes were considered excellent in 32% of cases, good in 16%, and poor in 52%.…”

“…The results of management of periprosthetic fractures have varied greatly due to factors such as bone quality, fracture pattern and method of treatment including nonoperative measures, reduction-fixation, or revision surgery. These treatments have historically been fraught with a high incidence of complications, treatment failures, and compromised outcomes [1][2][3][4][5][6][7][8][9][10][11][12][13]. Despite these problems, surgical treatment has become the standard in treating the majority of periprosthetic femur fracture [14].…”

Periprosthetic Fractures of the Femur After Hip Arthroplasty: An Analysis of 99 Patients

The medical records and radiographs of 99 patients treated for a periprosthetic femur fracture after total hip arthroplasty over a 17-year period at a single institution were prospectively reviewed. Fractures were classified according to the Vancouver system and stratified as to treatment method. Sixty-six patients had complete records available and a minimum of 12 months follow-up. Overall, 86% of the patients achieved fracture union. The success rate of cemented revision in the B2 and B3 groups was 84%, whereas cement-less revision was 86% successful. The complication rate of surgical treatment was 29%. Fracture union with a stable implant was possible in the majority of cases. Our results support the use of the Vancouver classification as a treatment algorithm.

“…However, in the light of the literature, is has not been clear if the incidence of periprosthetic fracture as a complication of THA is increasing. The overall incidence varies somewhere between 0.1 and 18% [1,6,11,12]. There prevails many options to treat periprosthetic fractures [7], revision operation being only one, and thus the incidence of revision-operated fractures has to be somewhat lower.…”

“…However, in the light of the literature, it is uncertain whether the relative incidence of periprosthetic fractures as a complication of THA is increasing or not. The overall incidence seems to vary somewhere between 0.1 and 18% [1,6,11,12]. As there are various operative protocols for the treatment, the incidence of fractures treated by revision arthroplasty has to be somewhat lower.…”

This study was based on data from the Finnish Arthroplasty Register. From 1990 to 1999, 33,154 primary hip arthroplasties were performed in Finland. Only periprosthetic fractures treated by a revision arthroplasty were registered. The six most used femoral components were compared using survival analysis and Cox's regression model. The incidence of periprosthetic fractures was calculated separately for the years 1990-1994 and 1995-1999. The incidence in the first period was greater than in the latter. Survival analysis and Cox's regression model showed that gender, prosthesis type and age were of no significance as risk factors for periprosthetic fractures.Résumé Cette étude a été basée sur les données du Registre finlandais des Arthroplasties. De 1990 à 1999 33.154 arthroplasties totales de la hanche ont été exécu-tées en Finlande. Seulement les fractures periprothéti-ques traitées par une arthroplastie de révision ont été enregistrées. Les six composants fémoraux le plus utilisés ont été comparés en utilisant l' analyse de la survie et le modèle de régression de Cox. La fréquence des fractures périprothetiques a été calculée séparément pour les années 1990-1994 et 1995 -1999 et elle était plus élevée dans la première période que dans la deuxième. L'analyse de la survie et le modèle de Cox ont montré que le sexe, le type de prothèse et l'âge n'étaient d'aucune signification comme facteur de risque pour ces fractures péri-protèthiques.

“…These positions are both weak points of the femur where the fractures are prone to occur. In the design of the prosthesis, the structural strength of the stress concentration positions should be taken into consideration to avoid the periprosthetic fractures [8].…”

Abstract. As the largest and longest bone in the human body, the femur has important research value and application prospects. This paper introduces a fast reconstruction method with Mimics and ANSYS software to realize the heterogeneous modelling of the femur according to Hu distribution of the CT series, and simulates it in various situations by finite element analysis to study the mechanical characteristics of the femur. The femoral heterogeneous model shows the distribution of bone mineral density and material properties, which can be used to assess the diagnosis and treatment of bone diseases. The stress concentration position of the femur under different conditions can be calculated by the simulation, which can provide reference for the design and material selection of prosthesis.
