Fractures of the sphenoid bone
Head & Neck Surgery, 1986AbstractFractures of the sphenoid bone occur following injury to the orbit and base of the skull. Such fractures are important since they can cause loss of vision and damage to various neural and muscular tissues. Ocular injury is also commonly associated. This paper reviews the hospital records of 112 consecutive patients with fractures of the base of

Bone fracture and bone fracture repair
Osteoporosis International, 2011Fracture healing is a multistage repair process that involves complex, well-orchestrated steps initiated in response to tissue injury. The early upregulation of IL-6, osteoprotegerin (OPG), VEGF, and BMPs indicates a central role for these factors in the initiation of cartilage and periosteal woven bone formation.

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.

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.

Temporal bone injury is frequently associated with severe brain injury which limits the clinical evaluation and detracts from the clinical signs of temporal bone fracture such as sensorineural hearing loss, conductive hearing loss, and facial nerve paralysis. Radiologists are often the first to note the presence of temporal bone fractures and should be

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 ...

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.

Summary This paper presents a statistical report of 615 fractures of the facial bones treated on the Plastic and Maxillofacial Surgery Service at Kings County Hospital during the years 1950 through 1954. A comparison of these figures is made with the figures covering an eighteen-month period and 212 cases at the same hospital during the years 1943 ...

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,
