Abstract:
Hamate fractures are rare injuries, frequently associated to dislocation of the ring and little fingers at the hamate-metacarpal joint. Its diagnosis is difficult, leading to delays in diagnosis. A strong clinical suspicion and appropriated radiographic exams are essential. The authors present a series of three clinical cases of fracture of the unciforme with carpometacarpal dorsal dislocation of the 4 masculine and 5 masculine fingers. For each case, they discuss the diagnosis, radiographic study, treatment and prognostic.

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 procedure...

The anterior compartment muscles originate from the humerus. They primarily function as flexors and are also known as flexor muscles. They typically insert on the carpals, metacarpals, and phalanges. The superficial layer includes the flexor carpi radialis,...
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...
