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

School belonging:the importance of student and teacher relationships

Abstract School belonging is associated with a range of positive educational and developmental outcomes, including psychosocial health and wellbeing, prosocial behaviour and academic achievement, and transition into adulthood. However, an increasing number of students worldwide report not feeling a sense of belonging to their school. There is growing research evidence that strong student–teacher relationships can promote school belonging, however creating these relationships within highly complex educational systems can be challenging. Further, only a few interventions focusing specifically on belonging that are available in schools have been found to be effective. This chapter highlights the importance of teacher support for a student’s sense of school belonging, discusses challenges associated with student–teacher relationships, and points to strategies for building strong relationships. We highlight the role that school leaders play in fostering strong relationships, and consider extensions within higher education, and future directions. Considering the importance of student–teacher relationships towards a student’s sense of school belonging, and the empirical base that points to both short- and long-term outcomes, implications for widespread benefits are possible for schools that prioritize and value positive relationships between staff and students

Fracture fixation in the operative management of hip fractures (FAITH): an international, multicentre, randomised controlled trial

Background Reoperation rates are high after surgery for hip fractures. We investigated the effect of a sliding hip screw versus cancellous screws on the risk of reoperation and other key outcomes. Methods For this international, multicentre, allocation concealed randomised controlled trial, we enrolled patients aged 50 years or older with a low-energy hip fracture requiring fracture fixation from 81 clinical centres in eight countries. Patients were assigned by minimisation with a centralised computer system to receive a single large-diameter screw with a side-plate (sliding hip screw) or the present standard of care, multiple small-diameter cancellous screws. Surgeons and patients were not blinded but the data analyst, while doing the analyses, remained blinded to treatment groups. The primary outcome was hip reoperation within 24 months after initial surgery to promote fracture healing, relieve pain, treat infection, or improve function. Analyses followed the intention-to-treat principle. This study was registered with ClinicalTrials.gov, number NCT00761813. Findings Between Mar
