Trocantheric Femoral Fractures - a retrospective cohort study comparing reoperation rates before and after implementation of new treatment protocolSmith, Sean January 2020 (has links)
Introduction: Hip fractures are very common in Sweden. Keeping reoperation rates as low as possible is critical. One factor correlated to mechanical complications and thereby reoperation rates is the tip-apex distance. In April of 2017 the Orthopedic clinic at Karlstad’s Central Hospital in Sweden implemented new routines for the choice of treatment method of pertrocantheric and subtrocantheric femoral fractures. Aim: The primary aim of this study was to compare reoperation rates of pertrocantheric and subtrocantheric femoral fractures before and after implementation of new routines. Secondly, we wanted to study the association between the tip-apex distance and reoperation rates for pertrocantheric femoral fractures treated at Karlstad’s Central Hospital. Method: This was an internal quality control designed as a retrospective cohort study. Data on patients treated for pertrocantheric or subtrocantheric femoral fractures were retrieved from the Swedish Fracture Registry. Tip-apex distances were measured on patients’ radiographic images. P-values for comparison of the two study periods were created using the chi2 test. Association between the tip-apex distance and reoperation rate was presented as odds ratio. Result: The reoperation rates were the same for both time periods. The reoperation rates of unstable fractures were lower for the study period after implementation of new routines. Neither of these results were statistically significant. There was also no statistically significant association between the tip-apex distance and reoperation rates. Conclusion: No statistically significant decrease in reoperation rates was seen after implementation of new routines. There was no association between the tip-apex distance and reoperation rates.

FE Modelling Of Two Femur Fixation ImplantsArsiwala, Ali, Shukla, Vatsal January 2021 (has links)
In the pool of women over the age of 50, the likeliness of an atypical fracture increase drastically, partly due to osteoporosis. With a pre-existing implant in the femur bone, inserted due to a prior atypical fracture, treating a later femoral neck fracture is complex and risky. Currently, a fractured femoral diaphysis is treated using an intermedullary nail which is fixed to the femur bone either through the femoral neck (Recon locking method)or through the lesser trochanter (Antegrade locking method). In a study conducted by Bögl et.al. JBJS102.17 (2020), pp. 1486-1494, it is found that the fixation of the intermedullary nail through the femoral neck reduces the risk of future femoral neck fractures. The study also states that more than 50% of the patients with atypical femoral fractures related to bisphosphonate treatment for osteoporosis (within the study sub population) were treated with the Antegrade locking implant. There does not exist much literature that reasons as to how one locking method is showing lesser risk of re-operation as compared to the other. The purpose of this study is to look into the effects these two implants have on the femur bone using the Finite Element Analysis (FEA). The study presented is aimed at comparing the results of the finite element analysis for the Recon implant model (Recon model) and Antegrade implant model (Antegrade model). The femur model without the implants (native bone model) is used to verify material behavior, while the other two are used for the comparison to study the stress-strain distribution, primarily in the neck region. This is a patient specific study, hence the femur bone model is generated using patient Computed Tomography (CT) scans. The bone model was assigned a heterogeneous isotropic material property derived from patient CT data. The finite element (FE) model of the bone was meshed using Hypermesh. The peak loading condition including the muscle forces were applied on the native bone model along with the Recon and the Antegrademodel. While the loading conditions during normal walking cycle were only applied to theRecon and the Antegrade model to compare the impacts of the two implant types. Both loading conditions were simulated by fixing the distal condyle region of the bone. The analysis results show that the Antegrade implant experiences much higher stresses and strains in the neck region as compared to Recon implant. Also, the presence of the intermedullary nail through the femur diaphysis helps to distribute the stresses and strains in the anterior distal diaphysis region of the bone. For the case of no implants, the model showed strains and stresses in the lateral distal region of femoral diaphysis.

Femurfrakturen bei Kindern und Jugendlichen / Femoral fractures in children and adolescentsGutberlet, Friederike 16 October 2012 (has links)
Bei der Behandlung kindlicher
Femurfrakturen ist es wichtig die Besonderheiten des kindlichen
Knochens zu berücksichtigen. Resultierende Beinlängendifferenzen
sowie die psychosoziale Belastung der Kinder stellen Probleme in
der Therapie dar. Ziel der vorliegenden Studie war es unter
Berücksichtigung dieser Aspekte einen Vergleich konservativer und
operativer Therapieverfahren im Verlauf der Jahre herzustellen.
Zugrunde gelegt wurden die Daten von 210 Kindern und Jugendlichen,
die in dem Zeitraum von 1992 bis 2008 in der Universitätsmedizin
Göttingen an einer Femurfraktur behandelt wurden. Als
komplikationsarmes und kindgerechtes Verfahren hat sich in den
letzten Jahren die Elastisch Stabile Intramedulläre Nagelung (ESIN)
immer mehr durchgesetzt. Sie stellt mittlerweile bei Kindern über
vier Jahren das Verfahren der Wahl dar. Die Verwendung der
Plattenosteosynthese und des Fixateur externe hat deutlich
abgenommen und sollte nur noch Spezialindikationen vorbehalten
sein. Bei Kindern unter vier Jahren kann ebenfalls die ESIN mit
guten Ergebnissen verwendet werden. Eine Alternative stellt in
dieser Altersgruppe der Beckenbeingips dar. Die Extensionsverfahren
werden auf Grund der vielen Nachteile, vor allem in psychosozialer
Hinsicht, so gut wie nicht mehr verwendet.
