Retrospective Cohort Study OBJECTIVES: The AOSpine Sacral Classification System was proposed as a comprehensive and universally accepted new classification for Sacral Fractures, and was recently internally validated. However, an external, independent and multidisciplinary reports on validation of this classification is lacking. Aim of the present study is to analyze the interobserver reliability and intraobserver reproducibility of the AOSpine Sacral Classification System for Sacral Fractures between orthopedic spinal and pelvic surgeons with different levels of experience. ⋯ Our findings confirmed the reliability and reproducibility of this classification in clinical practice. In the current study the surgeon's expertise (pelvic and spinal trauma) and the level of experience does not influence the reliability of the classification system.

Ambulance dispatch algorithms should function as clinical prediction rules, identifying high acuity patients for advanced life support, and low acuity patients for non-urgent transport. Systematic reviews of dispatch algorithms are rare and focus on study types specific to the final phases of rule development, such as impact studies, and may miss the complete value-added evidence chain. We sought to summarise the literature for studies seeking to improve dispatch in trauma by performing a scoping review according to standard frameworks for developing and evaluating clinical prediction rules. ⋯ Few derivation and validation studies were followed by an impact study, indicating important gaps in the value-added evidence chain. While impact studies suggest clinician oversight may enhance dispatch, the opportunity exists to standardize outcomes, identify trauma-specific low acuity codes, and develop intelligent dispatch systems.

In the early stage of fracture fixation, the aim of a unilateral external fixator (UEF) to stimulate healing and maintain stability may be suppressed by using inadequate number of pins. Cortical thinning due to age or osteoporosis endangers a successful fracture fixation. ⋯ This study suggests that initial instability due to cortical thinning can be efficiently alleviated by adding the number of pins up to 3 in a UEF; additionally, it may improve the knowledge about applying UEFs adequately stable, whilst promoting inclination toward endochondral ossification, simultaneously.

To compare the responsiveness of the Patient-Reported Outcomes Measurement Information System Physical Function (PROMIS-PF) to the 36-Item Short Form Survey Physical Component Score (SF36-PCS) in orthopaedic trauma patients from pre-injury to one year recovery. ⋯ PROMIS-PF has a more favourable responder burden based on lower time to completion and comparable responsiveness to the SF-36 PCS. However, there are limitations in responsiveness with the PROMIS-PF in patients who are higher functioning as demonstrated by the ceiling effects in patients at baseline pre-injury and at 12 months post-injury timepoints.

The aim of this study was to investigate the association between Parkinson's disease (PD) and postoperative complications, mortality, and quality of in-hospital care in patients with hip fracture. ⋯ Hip fracture patients with PD have a higher risk of infections and mortality within 30 days after surgery after adjustment for sex, age, and comorbidity. They do, however, receive comparable quality of in-hospital care after hip fracture compared to non-PD patients.
