Morbidity and mortality of fragility proximal humerus fractures: a retrospective cohort study of patients presenting to a level one trauma center.

Purpose: Fragility fractures are a significant source of morbidity and have high associated mortality. Identifying risk factors for poor outcomes is essential for guiding treatment and for setting expectations for patients and their families. Although fragility hip fractures have been abundantly explored, there is a paucity of information regarding proximal humerus fractures (PHFs).

Patterns of concomitant injury in thoracic spine fractures.

Background: Thoracic spine fractures (TSFs) are rarely isolated injuries, and they tend to present with a characteristic set of vertebral and non-vertebral injuries based on mechanism of injury. There is limited research on the rates and distribution of injuries that occur concurrently with TSFs. The purpose of this study is to characterize the distributions of these injuries by region of the body and by mechanisms of injury, so that trauma and spine surgeons can efficiently evaluate and treat patients presenting with TSFs.
