Factors Associated with Revision Surgery after Internal Fixation of Hip Fractures

Background: Femoral neck fractures are associated with high rates of revision surgery after management with internal fixation. Using data from the Fixation using Alternative Implants for the Treatment of Hip fractures (FAITH) trial evaluating methods of internal fixation in patients with femoral neck fractures, we investigated associations between baseline and surgical factors and the need for revision surgery to promote healing, relieve pain, treat infection or improve function over 24 months postsurgery. Additionally, we investigated factors associated with (1) hardware removal and (2) implant exchange from cancellous screws (CS) or sliding hip screw (SHS) to total hip arthroplasty, hemiarthroplasty, or another internal fixation device. Methods: We identified 15 potential factors a priori that may be associated with revision surgery, 7 with hardware removal, and 14 with implant exchange. We used multivariable Cox proportional hazards analyses in our investigation. Results: Factors associated with increased risk of revision surgery included: female sex, [hazard ratio (HR) 1.79, 95% confidence interval (CI) 1.25-2.50; P = 0.001], higher body mass index (fo

Hacker-engineers and their economies: The political economy of decentralised networks and ‘cryptoeconomics’

Research by political economists typically highlights policymakers, regulators, economists and consultants as the makers of economies. This paper foregrounds a different actor entirely, what I call the ‘hacker-engineer’ as an important protagonist in the making of decentralised digital network economies that are forged through the emerging field of ‘cryptoeconomics’ and blockchain and other distributed ledger technologies. Responding to critical literature stating that blockchain and ‘cryptoeconomics’ merely extend neoliberal processes of economisation, the paper recovers the neglected hacker culture of cypherpunk and histories of peer-to-peer decentralised networks in order to foreground concerns that depart from the continuation of economics and economies as usual. Hacker-engineers are dedicated to decentralisation as a ‘disruptive’ response to network control and surveillance, and share a pragmatist sensibility that seeks to make decentralised networks ‘work’ in order to provide informational security and privacy. While further broadening the range of agents that provide the focus for political economy research into the production of economies, the paper also draws attention to the technical decisions of hacker-engineers that attempt to reconfigure the material infrastructures of digital economies
