摘要： Embodiments of the present invention provide rotationally asymmetric bone screws. Embodiments of the present invention provide mechanisms that reduce the bending stiffness of conventional shaft bone screws in order to yield a less-rigid fixation construct. Such a less-rigid construct enables a controlled amount of motion at a fracture site which in turn promotes bone healing. As a means to reduce the bending stiffness of positive-locking bone screws, embodiments of the present invention provide a bone screw having a non-circular cross-section over parts of the screw length and/or longitudinal slots along at least a portion of the bone screw.

摘要： Embodiments provide protective helmets configured to protect the head from linear and rotational acceleration in an impact. In various embodiments, the helmets may include an outer layer, an inner layer, and at least one intermediate layer coupled to the outer and inner layers by alternate fixation sites, thereby providing a suspension between the outer and inner layers. In various embodiments, the intermediate layer may be made from a honeycomb material, such as an aluminum honeycomb. In use, in-plane deformation of the honeycomb may allow for translation of the outer layer in a substantially tangential direction relative to the inner layer, thereby mitigating rotational acceleration imparted by the tangential impact component. Additionally, crumpling of the honeycomb in a substantially non-elastic manner may deplete impact energy to minimize the elastic rebound that can contribute to linear and rotational head acceleration, thereby mitigating linear acceleration imparted by the perpendicular impact component.

摘要： Embodiments herein employ a novel strategy based on a floating cellular liner that acts as a torsional suspension system to dampen rotational acceleration, such as head acceleration in a helmet, in response to an oblique impact. Specifically, the torsional suspension consists of an anisotropic cellular liner that is at least partially recessed inside a more rigid adjacent shell, relative to which the cellular liner can simultaneously undergo translation and in-plane compression.

摘要： Embodiments of the invention provide bone plates with an upper surface, a lower surface, and a longitudinal plate portion for fixation to a bone shaft. A longitudinal plate portion may have three or more non- collinear holes for locking screws, whereby the axis of at least one hole may be angled relative to the axis of another hole to improve the torsional strength of the plate-bone construct.

摘要： Embodiments provide methods, apparatuses, and systems for fixation of a fractured bone. In various embodiments, the systems and plates may provide elastic suspension of the receiving holes relative to the osteosynthesis plate. This elastic suspension may promote load distribution between the screws that connect a bone segment to the plate, thereby reducing stress risers and load shielding effect. In addition, stress at the screw holes, and within the construct as a whole, is reduced by incorporation of these elastic elements in the plate. Additionally, in some embodiments, for instance if fracture healing by callus formation is desired, elastic suspension of the receiving holes relative to the osteosynthesis plate may enable small, controlled amounts of relative motion between bone fragments connected by the plate, which may promote fracture healing by callus formation.
摘要翻译：实施例提供了用于固定骨折骨的方法，装置和系统。在各种实施方案中，系统和板可以相对于骨接合板提供接收孔的弹性悬浮液。这种弹性悬挂可以促进将骨段连接到板的螺钉之间的负载分布，从而减少应力提升和负载屏蔽效应。此外，通过将这些弹性元件结合在板中，减少了螺钉孔和整个结构内的应力。另外，在一些实施方案中，例如，如果需要愈伤组织形成的骨折愈合，接收孔相对于骨接合板的弹性悬浮可以使得能够通过板连接的骨碎片之间的相对运动受到很小的控制，这可以促进骨折愈合通过愈伤组织形成。
