Characterized by their low modulus and high stretchability, soft composites have recently attracted great interest from researchers in related areas. The main objective of the present study is on the fracture property and toughening mechanism of soft composites. Two types of soft composites will be studied: soft elastic foam and the double-network (DN) composite. A theoretical/numerical study i...

BACKGROUND Osteoporotic fractures cause a large health burden and substantial costs. This study estimated the expected fracture numbers and costs for the remaining lifetime of postmenopausal women in Germany. METHODS A discrete event simulation (DES) model which tracks changes in fracture risk due to osteoporosis, a previous fracture or institutionalization in a nursing home was developed. Ex...

BACKGROUND Denture repair involves joining two parts of a fractured denture with a denture repair material. Hence, a substantial repairing system for denture base fracture should be there to elude frequent fracture. MATERIALS AND METHODS Surface treatment of conventional heat cure denture base resin with different surface treatments (chemical ethyl acetate, and mechanical roughening with bur)...

Fracture of the anterior skull base can occur following head injury. Growing skull fracture is usually observed in children under age of 3-years. It commonly involves frontal and parietal regions. However, orbit involvement is extremely uncommon. Authors report a case of giant orbital encephalocele with a forehead disfiguring swelling in a 4-years boy, who sustained head injury about 3½ years b...

Although prior falls are a well-established predictor of future fracture, there is currently limited evidence regarding the specific value of falls history in fracture risk assessment relative to that of other clinical risk factors and bone mineral density (BMD) measurement. We therefore investigated, across the three Osteoporotic Fractures in Men (MrOS) Study cohorts, whether past falls predic...

INTRODUCTION Isolated dislocations of the trapezio metacarpal joint without associated fracture has been reported very rarely in the literature. There are reports of associated injuries like fracture of the trapezium, dislocation of the metacarpophalangeal joint and fractures of the base of the thumb metacarpal. CASE REPORT Authors report a case of isolated carpometacarpal dislocation of the ...

Trapezoid bone fracture is the least common fracture owing to the fact that it is strictly bounded to scaphoid, capitate and the base of the second metacarpal. Isolated fractures are rarely seen and usually related to the high energy trauma. It is conservatively treated without dislocation. Triquetrum fractures are the second least common fractures among carpal bones. The body fractures are usu...

Coracoid fractures are uncommon injuries, in isolation or in association with other osseoligamentous injuries about the shoulder girdle. We report a case of successful operative management of symptomatic ipsilateral nonunions of a type I coracoid base fracture and a lateral one-third clavicular fracture, which developed following nonoperative treatment of this exceedingly rare injury pattern. F...
