Background: The cesarean section rate following a pelvic fracture is more than double the standard norms. This results from residual deformity and a lack of knowledge among obstetricians regarding the ability to deliver vaginally after a pelvic fracture. Aim: To present a case of pelvic fracture that delivered vaginally indicating vaginal delivery is possible even after pelvic fractures that ar...

We report the first case of a combined bony and soft tissue Chance fracture in the thoracic spine, with late presenting displacement following conservative management. Chance fractures are flexion-distraction injuries to the spine. They consist of disruption and longitudinal separation of the posterior elements of the vertebra, with the fracture extending through the pedicles and into the verte...

Fracture-dislocations of the elbow remain among the most difficult injuries to manage. Historically, the combination of an elbow dislocation, a radial head fracture, and a coronoid process fracture has had a consistently poor outcome; for this reason, it is called the terrible triad. An elbow dislocation associated with a displaced fracture of the radial head and coronoid process almost always ...

We describe experiments on the dynamic fracture of the brittle plastic, PMMA. The results suggest a view of the fracture process that is based on the existence and subsequent evolution of an instability, which causes a single crack to become unstable to frustrated microscopic branching events. We demonstrate that a number of long-standing questions in the dynamic fracture of amorphous, brittle ...

Diaphyseal fractures of the metacarpals and phalanges are common injuries that can lead to impairment of hand function. The fracture pattern and soft-tissue injury vary with the mechanism of injury. The imbalance of the flexor and extensor forces created by displaced fractures will often produce a secondary angulatory deformity. Nonoperative treatment is indicated for reducible and stable fract...
