Diaphyseal fractures of the femur and tibia in adults are mostly treated surgically, usually by means of intramedullary locked-nail osteosynthesis. Some comminuted and/or highly deviated shaft fractures may present a veritable technical challenge. Fracture (or orthopedic) tables, which enable vertical, horizontal and rotational instrumental stabilization of the limb, greatly facilitate reductio...

Tibia and fibula shaft fracture are common among young old, if they not managed correctly, can be debilitating in long term. Management of these fractures depends on severity,stability, pattern fracture. Options range from conservative management by plate to external fixation, especially the case an open Unfortunately, ideal fixation option (commonly used or nail) implant is always available op...

ABSTRACT The new design of a modified lower limb of the Polar-II pedestrian dummy for enhanced biofidelity requires establishment of an alternative instrumentation to load cells. The objective of this study was to determine injury thresholds for the thigh and leg of the modified dummy, and to establish an alternative measurement technique. FE pedestrian impact simulations were run using full-bo...

In this study of fractures of the shaft of the tibia and femur in children, the growth rate of these long bones after injury was assessed by serial radiographical measurements of bone length, accurate to the nearest millimetre. Within three months of injury the rate of growth was at its maximum and was 38 per cent in excess of normal. The rate then decreased but remained significantly raised fo...

The purpose of the present study was to compare the therapeutic effects of risedronate (RIS) and alfacalcidol (ALF) on cancellous and cortical bone in ovariectomized osteopenic rats. Forty-two female Sprague-Dawley rats, 7 months of age, were randomized by the stratified weight method into six groups: the sham-operated control (Sham) group, and five ovariectomized groups: treated with vehicle, ...

BACKGROUND This study was performed to evaluate when patients recover sufficiently to drive an automobile after operative repair of various other lower extremity fractures. METHODS A computerized driving simulator was developed and tested. Three groups of individuals were compared: (1) 12 healthy, volunteers tested once to establish normal mean values for variables tested (group I); (2) 22 pa...

To investigate the clinical characteristics of chondroblastoma with an emphasis on lesions located in the long bone diaphysis, we reviewed the clinical data of 7 patients with histologically proven chondroblastoma treated in Tianjin Medical University Cancer Hospital and Fudan University Cancer Hospital between January 1995 and May 2009. There were two rare cases of chondroblastoma in the long ...
