Abstract: According to an aspect of some embodiments there is provided a bone anchor including an elongated core having a tip at a distal end and coupled to a head at a proximal end, and a segmented helical thread defining one or more gaps therein, each gap defining at least a trailing wall, the trailing wall having a cutting surface including at least one cutting edge. The bone cutting surface and the cutting edge configured to cut bone and guide bone fragments radially inwards. According to an aspect of some embodiments there is further provided a bone anchor kit and a method for implanting the bone anchor in bone.

Abstract: A Universal implant-to-bone anchoring system including an anchor having a shaft terminated at one end by a head and one or more tins, generally planar and having two surfaces, portions of which come together at a free edge, and attached to the shaft and angled about a minor radius thereof along an imaginary helix and an inserter operative to be attached to the head of the anchor and having one or more ports operative to accommodate an anchor driving tool.

Abstract: A system and method for low-dosage imaging is particularly suited to diagnosis of dislocated hips in newborn babies. The minimum required dosage of radiation required to form an image is derived on the basis of the measured weight of the subject, typically by use of look-up tables. For diagnosis of dislocated hips, a tensile force is preferably applied to the leg of the subject so as to generate a temporary cavity within the hip in accordance with the vacuum phenomenon. An image is then formed of soft tissue surrounding the cavity. This allows the hip to be identified as either a normal hip or a malformed hip in accordance with the shape of the cavity. The system typically employs two very low dosage X-ray pulses of differing frequencies which are directed through the subject's hip toward a stimulated emission secondary source. The resulting images are sensed using a full-frame CCD, and are combined to form a composite image containing both hard tissue and soft tissue information.
