The diagnosis of instability in the apparent, isolated distal fibula fracture can be challenging and often necessitates stress radiography. Danis & Weber classified lateral malleolar fractures based on the level of the fracture in relation to the syndesmosis. While Weber B fractures occur at the level of the syndesmosis, some such injuries present with a long, oblique pattern extending well above the syndesmosis. Given the well-established literature demonstrating that fractures above the syndesmosis correlate with a higher level of concomitant syndesmotic and deltoid ligament injury, we hypothesize that increased fracture obliquity, length and height of Weber B fibula fractures similarly correlates with increased mortise instability. ⋯ Increased fracture obliquity, length and height of Weber B fibula fractures did not correlate with a higher incidence of mortise instability. Despite the lack of positive correlation, future studies should continue to investigate and identify radiographic parameters of distal fibula fractures that are most predictive of instability.

We aimed to determine whether the outcome of severely injured patients differs based on admission time (office hours vs. non-office hours) at a tertiary trauma centre without an in-house trauma surgeon consultant available at all times. We also studied subgroups of patients presenting with a New Injury Severity Score (NISS) ≥ 25 and patients experiencing major bleeding. ⋯ We found that arrival time did not affect mortality among patients with severe blunt trauma treated at a tertiary trauma centre without an in-house trauma surgeon consultant available at all times. Thus, this type of unit can maintain a standard of care during non-office hours by investing in precise treatment protocols and continuous education. However, our results do not apply to penetrating trauma injury patients.

A recent proposal suggests changing the threshold for statistical significance from a P value of .05 to .005 to minimize bias and increase reproducibility of future studies. P values less than .05 but greater than .005 would be reclassified as "suggestive", whereas P values less than .005 would be considered significant. The present study explores how lowering the P value threshold would affect the interpretation of previously published orthopaedic trauma randomized controlled trials (RCTs) and whether outcomes from these trials would maintain statistical significance under the proposed P value threshold. ⋯ Based on our results, adopting a lower threshold of significance would heavily alter the significance of orthopaedic trauma RCTs and should be further evaluated and cautiously considered when viewing the effect such a proposal on orthopaedic practice.

The incidence of invasive treatment of rib fracture has increased significantly over the last decade however the evidence of improved patient outcomes to support this is lacking. A systematic review was performed to identify patient reported outcome measures (PROMs) used in the assessment of outcomes following chest wall injury. The quality of evidence for the psychometric properties of the identified PROMs was graded using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) methodology. ⋯ The lack of validated outcome measures for rib fracture patients is a significant limitation of the current literature. Further studies are needed to provide validated outcome measures to ensure accuracy of the reported results and conclusions. As interventions for rib fractures have become more common in both research and clinical practice this has become an urgent priority.
