Hybrid fracture and the transition from extension fracture to shear fracture
Nature, 2004Fracture is a fundamental mechanism of material failure. Two basic types of brittle fractures are commonly observed in rock deformation experiments--extension (opening mode) fractures and shear fractures. For nearly half a century it has been hypothesized that extension and shear fractures represent end-members of a continuous spectrum of brittle ...

Stress Fractures (Fatigue Fractures, Marsh-Fractures)
2009In consequence of cyclic long-continued or oft-repeated stress like prolonged walking, dancing, or running, infraction or complete fracture can develop on certain sites of the skeleton. There is no specific single causative injury in the history, like in trauma-related fractures.

The Frenchman's fibular fracture (Maisonneuve fracture)
Journal of the American College of Emergency Physicians, 1979Two patients with injuries to the ankle sustained by rotational trauma complained only of pain in the ankle. Careful examination revealed tenderness over the proximal fibula. Subsequent radiographic studies revealed high helical fracture of the fibula, as originally described by Maisonneuve.

Subcapital Fracture Complicating an Intertrochantenc Fracture
Clinical Orthopaedics and Related Research, 1985A previously undescribed type of fracture of the neck of femur occurred following intertrochanteric fracture fixation with a McLaughlin nail plate in an 80-year-old woman. This complication was probably caused by prolonged non-weight-bearing and inadequate fixation.

Fracture and Fracture Mechanics
1981Griffith was the first to offer an explanation for brittle fracture. He postulated that in a brittle material, cracks propagate when the released strain energy is just sufficient to provide the surface energy for the creation of new surfaces. That is elastic strain energy per unit volume = σ2/2E, where σ = stress applied perpendicular to the crack, E =
