Multicenter Study
Update of the CHIP (CT in Head Injury Patients) decision rule for patients with minor head injury based on a multicenter consecutive case series.
To update the existing CHIP (CT in Head Injury Patients) decision rule for detection of (intra)cranial findings in adult patients following minor head injury (MHI). ⋯ Use of the updated CHIP decision rule is a good alternative to current decision rules for patients with MHI. In contrast to the original CHIP the update identified all patients with (potential) neurosurgical lesions without increasing CT rate.

Management and outcomes of rib fractures in patients with isolated blunt thoracic trauma: Results of the Aotearoa New Zealand RiBZ study.
Rib fractures are common and associated with significant morbidity and mortality. There is limited literature on patient care and outcomes in Aotearoa New Zealand (AoNZ). The aim of this study is to describe key clinical outcomes and management interventions for patients with rib fractures across AoNZ. ⋯ This study describes clinical outcomes for patients with isolated rib fractures from multiple hospitals in AoNZ. A moderate pneumonia rate of 11% was found which is likely amendable to reduction with quality improvement initiatives. Consideration should be given to further resource and improve the access to SSRF and regional analgesia given the low utilization found across AoNZ. A higher re-presentation rate in Māori and elderly patients was found which needs further investigation.

One of the complications of the surgical therapy for proximal humerus fractures is fracture-related infection (FRI). This multicenter study aimed to investigate the incidence of FRI and clarify the risk factors associated with FRI in patients receiving open reduction and internal fixation for proximal humerus fracture. ⋯ This study revealed an infection rate following open reduction and internal fixation of proximal humerus fracture of 1.8% (9 patients) and that Staphylococcus was the most frequent causative organism. Glenohumeral fracture dislocation is a significant risk for postoperative FRI.

Pre-and postoperative factors associated with functional outcomes in patients with posterior malleolar fractures.
Recent studies on posterior malleolar fractures mainly focus on the reduction quality and fixation of the posterior fragment since it contributes to ankle stability and articular congruency. However, the association of pre-and postoperative factors considering the whole ankle joint in postoperative functional outcomes remains unclear. Therefore, this study aimed to examine the association between pre-and postoperative variables for postoperative functional outcomes in patients with posterior malleolar fragments (classified as Haraguchi type I or II) and considered the association between reduction and fixation for small posterior malleolar fragments of less than 25% of the intra-articular surface. ⋯ Our results suggest that postoperative complications were associated with AOFAS scores at postoperative 12 months in patients with ankle fractures with posterior malleolar fragments. In patients with small posterior malleolar fragments, reduction and fixation were not associated with AOFAS scores. Therefore, clinical decisions for posterior fragment fixation should be made based on the possible risk of complications related to the surgical procedures in addition to the posterior malleolar fragment size.
