Background: Rib fracture pain is a major issue but likely underappreciated, given that patients avoid activity due to the pain. Pain is one criterion used to determine if someone is a candidate for surgical stabilization of rib fractures (SSRF). The purpose of this study was to assess pain for rib fracture patients, hypothesizing pain from rib fractures is underappreciated in current practice.

Article Synopsis
  • Surgical stabilization of rib fractures (SSRF) can benefit patients, but only about 29.1% of those who qualify actually receive the procedure at the studied trauma center.
  • The study involved a review of 3,432 rib fracture patients from 2016 to 2023, determining criteria based on the 2023 CWIS SSRF Guidelines.
  • A significant portion of patients not undergoing SSRF had multiple potential reasons for the procedure but were managed without surgery, with "failure to wean from the ventilator" being the most common reason for SSRF consideration.

Article Synopsis
  • Surgical stabilization of rib fractures (SSRF) is being increasingly accepted, but there's debate on how many fractures need stabilization for optimal chest wall stability (CWS).
  • A finite element analysis was performed on different rib fracture scenarios to evaluate CWS after SSRF, focusing on cases with various patterns and stabilization approaches.
  • The results showed that stabilizing all rib fractures significantly improves CWS, while leaving some fractures untreated can worsen stability, particularly in cases with flail segments.

Article Synopsis
  • The study investigates how immigration status affects the use of disease-modifying drugs (DMDs) among multiple sclerosis (MS) patients in British Columbia, Canada, focusing on those with universal health coverage.
  • Researchers analyzed health data from MS patients between 1996 and 2012, including both immigrants and long-term residents, to determine the likelihood of filling a DMD prescription within five years of their first healthcare encounter related to MS.
  • Results indicated that while overall DMD use did not significantly differ between immigrants and long-term residents, lower socioeconomic status (SES) immigrants had reduced odds of filling DMD prescriptions.
