Beyond the break: development and validation of a new classification system for acute traumatic rib fractures

Trauma Surgery & Acute Care Open
Background Despite the high incidence and significant injury burden of rib fractures, a universally agreed-upon taxonomy for acute traumatic rib fractures (TARF) has not been established. We propose a novel TARF with three components: (1) the rib that is

Shear behavior of bolt–grout interfaces under constant normal stiffness: Influence of grout strength and thickness

Deep Underground Science and Engineering, EarlyView.
The effects of grout strength and thickness on the shear behavior of bolt–grout interfaces (BGI) under constant normal stiffness conditions are investigated. Shear strength, failure modes, and acoustic emission characteristics are examined. The findings reveal that grout strength exerts a significantly greater influence on BGI shear strength and ...

Attempted repair of chest wall injury following penetrating injury with surgical stabilization rib and autologous bone graft: A case report

Trauma Case Reports
Rib fractures are one of the most common injuries following blunt trauma. When associated with penetrating trauma, the projectile velocity and immense energy transfer cause significant rib fracture displacement and fragmentation.
