Journal of Applied Physics, 1970
Fracture of bone is investigated by measuring the energy required to propagate a crack and by observing, microscopically, the mechanism of fracture. At low strain rates bone displays very high resistance to crack propagation comparable even to some metallic materials. The type of fracture is similar to fiber-reinforced composite materials.

The American Journal of Emergency Medicine, 1995
The diagnosis and monitoring of patients presenting to an emergency department with blunt temporal bone fracture and complications requiring acute management were reviewed for a four-month period. Of 104 trauma patients with closed head injury, 15 patients were diagnosed with temporal bone fracture, 12 of whom survived their injuries.

FOR THE purpose of description, fractures of the facial bones may be divided into four groups: (1) fractures of the nasal bones ( recent and old); (2) fractures of the malar bone and superior maxilla (recent and old); (3) fractures of the mandible, and (4) fractures of all the facial bones.

Diagnosis and proper initial management of acute fractures of the carpal bones is critical because of the limited blood supply of many bones of the wrist and the role of the carpus in optimizing hand function. Pathology is correctly diagnosed by a focused history and examination.

Vitamin A is a generic term describing compounds that have the same biological activity as retinol. Dietary vitamin A can be obtained from "provitamin A" carotenoids (e.g., ß-carotene) found in plant foods such as carrots, cantaloupes, and sweet peppers, or as "preformed vitamin A" found in many dietary supplements, animal livers, and vitamin A ...

Carpal bone fractures make up a significant proportion of injuries to the wrist. The complex bone shape and articulations make diagnosis more difficult and missed injuries more common. This article reviews carpal bone fractures excluding the scaphoid.

Fractures of the carpal bones, excluding the scaphoid, are less common and are often missed on standard, plain radiographs. The diagnosis requires knowledge of the anatomy and common fracture patterns of the bones and the specialized radiographic views necessary to image them.

Radiology, 1959
Fracture of the hyoid bone is likely to prove fatal because of asphyxia. Sufficient stress to cause a hyoid fracture will frequently produce soft-tissue injuries which mask its presence unless the attending physician deliberately examines the bone radiographically, or familiarity with the clinical symptoms alerts him to its possibility. Conversely, the

The aim of this retrospective study was to evaluate the epidemiology, treatment, and complications of frontal bone fractures associated, or not, with other facial fractures. This evaluation also sought to minimize the influence of the surgeon's skills and the preference for any rigid internal fixation system.

Bone architecture and fracture
Current Osteoporosis Reports, 2005Bones are designed to carry out their requirements effectively. One of these requirements is to resist fracture. Two other important requirements are to be stiff and to be light. Few theories of adaptive modeling distinguish modeling for adequate stiffness from modeling for adequate strength. Bones achieve their architecture partially through genetics,
