Purpose:
Trapezoid fractures are rare. Mostly single cases reports appear in the literature. The purpose of this study was to review 11 patients treated for trapezoid fractures at our center.
Methods:
We reviewed all trapezoid fractures that presented over the past 10 years at our institution. We reviewed case notes regarding mechanism of injury, fracture pattern, mode of diagnosis, and time to diagnosis and treatment.
Results:
We treated 11 patients for trapezoid fractures over the 10-year period. A correct diagnosis was made in 5 cases on initial evaluation. Most trapezoid fractures were diagnosed on computed tomographic scan. The fracture plane was predominantly sagittal. Coronal fractures could not be diagnosed on plain radiographs.
Conclusions:
Fractures of the trapezoid should be suspected from the mechanism of injury, in particular, axial force, and from local tenderness. These fractures may be underdiagnosed. We recommend computed tomography rather than plain radiography alone in case of clinical suspicion.
Type Of Study/Level Of Evidence:
Diagnostic IV.

01:27Fractures: 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...
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...
