this study compares the functional capabilities of different metacarpal fixation constructs under physiological loadings in an attempt to identify the optimal construct rather than the strongest one. one hundred and twenty-six preserved human metacarpals were mechanically tested after oblique osteotomies and internal fixation. maximum load to failure, average structural rigidity, and energy abs...

Background: Controversy exists regarding the best technique for treating displaced transverse olecranon fractures with advocates three techniques: (1) intramedullary (IM) screw, (2) locking plate, and (3) tension band. Objectives: The aim of this study was to seek which method fixation fits according fracture type postoperative outcome. Two methods were used: K-wire band screw. Patients metho...

Many structural features of the mammalian central nervous system can be explained by a morphogenetic mechanism that involves mechanical tension along axons, dendrites and glial processes. In the cerebral cortex, for example, tension along axons in the white matter can explain how and why the cortex folds in a characteristic species-specific pattern. In the cerebellum, tension along parallel fib...

BACKGROUND Although the modified tension band technique (eg, tension band supplemented by longitudinal Kirschner wires) has long been the mainstay for fixation of transverse fractures of the patella, it has shortcomings, such as bad reduction, loosening of implants, and skin irritation. QUESTIONS/PURPOSES We conducted a retrospective comparison of the modified tension band technique and the t...
