Abstract:
We herein present a case of right triquetral fracture with associated pisiform and flexor carpi ulnaris subluxation in a 29-year-old man. Initial radiography showed a right triquetral fracture. Computed tomography and magnetic resonance imaging demonstrated a triquetral fracture with a subluxated pisiform. Open reduction and lag screw fixation of the right triquetrum was performed, with good subsequent recovery of function. Although triquetral fracture with subluxation of the pisotriquetral joint is uncommon, attending clinicians should bear in mind the possibility of such an injury when managing traumatic ulnar-sided wrist pain.

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...
