Background:
The aim of the present study is to analyse complications after a floating elbow injury, attempting to establish which of them act as a poor prognosis factor regarding clinical and functional results.
Materials And Methods:
Twenty-three patients who suffered a floating elbow injury, treated at our institution from 2004 to 2013, were retrospectively reviewed. Patients were divided into four groups depending on the type of injury. An analysis of demographic data, associated injuries, treatment options and complications was carried out. Clinical evaluation was made by a conventional goniometer, testing flexo-extension and prono-supination ranges. For functional evaluation, the Mayo Elbow Performance Score was employed. Association between radioulnar synostosis, articular surface disruption, nerve injury and clinical and functional results was analysed.
Results:
Patients with radioulnar synostosis had worse results in functional evaluation than patients without it (56.6 vs. 75); this difference was statistically significant (p = 0.05). Regarding intra-articular extension, we found statistical association with worse results in functional evaluation (p = 0.018); however, nerve palsy does not seem to influence functional results.
Conclusions:
Radioulnar synostosis and intra-articular extension of the injury are poor prognosis factor in floating elbow.

Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
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...

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...
