Fractures of the calcaneus

Journal of the Faculty of Radiologists, 1951
Summary 1. A series of one hundred consecutive cases of recent fracture of the calcaneus has been analysed. 2. The internal structure of the bone is briefly considered and the mechanism of compression fracture of the calcaneus is described. 3.

Sacral fractures

Neurosurgery, 1984
Abstract The sacral spine has received relatively little attention in the orthopedic and neurosurgical literature, in part because of the infrequency of developmental, degenerative, or neoplastic conditions of the sacrum requiring surgical intervention.

Role of MRI in hip fractures, including stress fractures, occult fractures, avulsion fractures

European Journal of Radiology, 2012
MR imaging plays a vital role in the diagnosis and management of hip fractures in all age groups, in a large spectrum of patient groups spanning the elderly and sporting population. It allows a confident exclusion of fracture, differentiation of bony from soft tissue injury and an early confident detection of fractures.

Hybrid fracture and the transition from extension fracture to shear fracture

Nature, 2004
Fracture 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)

2009
In 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, 1979
Two 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, 1985
A 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

1981
Griffith 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 =
