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.
Methods:
We retrospectively reviewed the trauma database records of 683 patients presenting with a TSFs at a single institution from 2015 to 2019. We recorded patient demographics, comorbidities, and associated injuries by body region. We characterized the TSFs using the AO classification system, as well as the presenting physical exam and treatment. All associated injuries among the TSF patients were classified into the following categories: head injury (HI), thoracic injury (TI), non-thoracic vertebral injury (NTVI), abdominal injury (AI), upper extremity injury (UEI), lower extremity injury (LEI), and spinal cord injury (SCI).
Results:
The three leading causes of TSFs were mechanical falls (38.4%), falls from height (24.9%), and motor vehicle crashes (MVCs) (23.4%). Patients with a TSF from MVC were statistically more likely to have concomitant injuries of TI, NTVI, AI, HI, UEI, and LEI. TSFs from fall from height were statistically more likely to have TI, NTVI, and LEI. TSFs from mechanical falls had significantly lower rates of all injury locations, but still presented with high rates of additional injury. TSFs from motorcycle crashes (MCCs) presented with TI, AI, UEI, and LEI. There were high rates of treatment for TSFs, with surgery ranging from 5.3% to 20.0% and bracing from 52.3% to 65.7% depending on mechanism of injury.
Conclusions:
TSFs after MVCs, mechanical falls, falls from height, and MCCs presented with a predictable pattern of injuries and were rarely an isolated injury. This cross-sectional data may help spine and trauma surgeons better understand patterns of injury associated with TSFs, with the hope of preventing missed injuries and better advising patients with TSFs on severity of injuries.

01:24Flail Chest-I
Flail chest is a severe and potentially life-threatening condition characterized by the fracture of three or more adjacent ribs in multiple places. It is most commonly caused by direct impacts and trauma, such as motor vehicle accidents or injuries from a steering wheel impact. It can also occur due to falls in elderly individuals with osteoporosis, or assaults involving sharp objects.
Pathophysiology
The pathophysiology of flail chest is complex, involving fractures of...

01:27Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...

Regions of the Vertebral Column
In an adult, the spine is subdivided into five regions: the cervical, the thoracic, the lumbar, the sacral, and the coccygeal region. The spine initially develops as a series of 33 vertebrae; after 20 years of age, the nine bones in the sacral region, five sacral, and four coccygeal bones fuse to form...
