In recent years, there has been tremendous interest in employing legged and humanoid robots for dangerous missions in disaster and rescue scenarios, requiring robots to operate swiftly and stably while dealing with high levels of uncertainty and large external disturbances. One such practical example is using a legged robot to carry and manipulate large and heavy objects whose mass is not known...

Grip strength during short and sustained maximal voluntary isometric contractions was measured in 28 females and 5 males with displaced Colles' fracture involving the distal radio-ulnar joint. The patients were randomized into two groups, treated either through immobilization with plaster cast or with external fixation. The recovery of isometric grip strength was followed over a two-year period...

Distraction osteogenesis has been used for more than 50 years to address limb-length discrepancy and deformity. Intramedullary fixation has been used in conjunction with external fixation to decrease the time in the external fixator and prevent deformity and refracture. A new generation of motorized intramedullary nails is now available to treat limb-length discrepancy and deformity. These nail...

The purpose of this study was to test and compare external fixator construct stiffness using pin-to-bar clamps or multipin clamps across 2 external fixation systems. Constructs were tested with 8-mm and 11-mm-diameter bar systems and pin-to-bar or multipin clamps. Three construct designs were tested: construct 1 with a single crossbar and pin-to-bar clamps, construct 2 with 2 crossbars and pin-...

OBJECTIVE To analyze the rigidity of a platform-type external fixator assembly, according to different numbers of pins on each clamp. METHODS Computer simulation on a large-sized Cromus dynamic external fixator (Baumer SA) was performed using a finite element method, in accordance with the standard ASTM F1541. The models were generated with approximately 450,000 quadratic tetrahedral elements...

External fixation combined with colostomy is a traditional management of the pelvic fractures associated with perineal lacerations. However, malunion and dysfunction caused by malreduction and loss of reduction are common. One-stage definitive fixation without soft tissue harassment is requisite for the treatment. The purpose of this study was to assess the outcome of 1-stage definitive fixatio...
