Fractures: Bone Repair01:27

Fractures: Bone Repair

Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
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...

Flail Chest-I

Overview of Flail Chest
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...
Bones of the Upper Limb: Ulna01:15

Bones of the Upper Limb: Ulna

The ulna and radius are parallel bones of the antebrachium or the forearm. The ulna lies medially and consists of a bony tip called the olecranon process at its proximal end. This hook-like projection articulates with the olecranon fossa of the humerus and forms the "hinged" ulnohumeral part of the elbow joint. This joint facilitates forearm extension and flexion while preventing its hyperextension. Similarly, the coronoid process, another bony projection on the proximal/anterior side of the...
Degenerative Disc Disease ll: Pathophysiology01:23

Degenerative Disc Disease ll: Pathophysiology

The symptoms of degenerative disc disease arise from a combination of mechanical compression, vascular compromise, and biochemical inflammation, which together disrupt nerve function and produce pain.Mechanical CompressionDisc degeneration reduces height and elasticity, predisposing to herniation of the nucleus pulposus, a major cause of radicular pain. Herniations may be protrusion (bulging with intact annulus), extrusion (nucleus extends beyond disc but remains connected), or sequestration...

Summary
This summary is machine-generated.

Perilunate dislocations and fracture-dislocations are severe wrist injuries requiring prompt diagnosis and surgical repair. While treatment aims to restore alignment, long-term outcomes often include persistent pain and reduced wrist function.

Area of Science:

  • Orthopedic Surgery
  • Traumatology
  • Radiology

Background:

  • Perilunate dislocations and fracture-dislocations stem from high-energy wrist trauma.
  • These injuries involve complex bony and ligamentous damage.
  • Radiographic signs of injury, like loss of carpal alignment, can be subtle and initially missed.

Purpose of the Study:

  • To summarize the key aspects of perilunate dislocations and fracture-dislocations.
  • To highlight the importance of prompt diagnosis and management.
  • To discuss common complications and long-term functional outcomes.

Main Methods:

  • Review of literature on perilunate injuries.
  • Description of typical radiographic findings.
  • Outline of acute management (closed and open reduction, internal fixation).

Main Results:

  • Prompt recognition and reduction are crucial for optimal outcomes.
  • Common complications include post-traumatic arthrosis, nerve dysfunction, and carpal instability.
  • Persistent pain and reduced wrist function are frequent despite treatment.

Conclusions:

  • Perilunate injuries require immediate attention to prevent long-term morbidity.
  • Radiographic evidence of arthrosis does not always correlate with functional deficits.
  • Management focuses on anatomical reduction and stable fixation to mitigate complications.
