Abstract:
High-energy trauma to the shoulder is associated with multiple injuries and is often difficult to evaluate. One of these complex traumas is the displacement of the humeral head into the thoracic cavity. This study aimed to report a patient who presented after falling three floors. Initially, the patient underwent chest drainage and thoracoscopy to remove the displaced humeral head and, subsequently, underwent delayed artificial humeral head replacement. Hemodynamic stability, systematic evaluation, removal of the humeral head, and individual shoulder reconstruction are recommended for these patients.

Flail 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...
Fractures: 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...
