Abstract: A medical imaging method is described for establishing implant configuration by measuring the positions and orientations of its components constrained by a defined kinematic relationship between them using stereo radiography images. The method allows the determination of a patient-specific implant configuration and enables accurate measurements of the pose of implant despite significant occlusions. The measurements obtained with this method can be used to determine the relative movement of an implant component relative to other components, bone or other landmark.

Abstract: A synchronized laser system for illuminating a sample with first and second laser light pulses, said system comprising: a trigger, said trigger being operative to issue first and second trigger signals, said first and second trigger signals being emitted at an adjustable frequency with a predetermined delay therebetween; a first tunable mode-locked laser operative for emitting said first laser light pulses in response to receiving a train of said first trigger signals, a first wavelength of said first laser light pulses being dependent on said adjustable frequency in accordance with a first wavelength-frequency relationship; a second tunable mode-locked laser operative for emitting said second laser light pulses in response to receiving a train of said second trigger signals, a second wavelength of said second laser light pulses being dependent on said adjustable frequency in accordance with a second wavelength-frequency relationship; wherein said predetermined delay is such that said first and second laser l

Abstract: The present invention relates to a device and use of the device for detection and loosening of implants installed into a subject's host bone, the device comprising: a frame for encircling and demountably engaging a portion of the subject's appendage comprising the host bone with installed implant; and at least three-spaced apart attachments engaged with the frame, wherein each attachment is configured to house and to retractably deploy a sharp geometry component for contacting the host bone, wherein a temporary reference frame is created when the three-spaced apart attachments contact the host bone. The use of the device comprises obtaining a first pair of stereo radiographs of the implant under a first loading condition and obtaining a second pair of stereo radiographs of the implant and host bone area under the second loading condition and comparing the two radiographs to detect displacement of the implant.

Abstract: A method of measuring the relative position of a bone implant within a bone in a patient to detect movement between the implant and bone is provided, wherein one or more radiopaque bone markers have been implanted into the bone through a cannulated implant within the bone and one or more radiopaque implant markers have been implanted into the implant. The method comprises: i) determining a first relative position of the bone marker to the implant marker under a first parameter; and ii) determining a second relative position of the bone marker to the implant marker under a second parameter, wherein a change in the position of the bone marker relative to the implant marker from the first relative position to the second relative position is indicative of movement of either the implant or the bone.

Abstract: The invention comprises a modified implant useful to assess bone by imaging. The modified implant comprises a medical implant and at least one detectable marker element associated with the implant that serves as a reference point in medical imaging. Preferably, the implant and the detector marker elements have different radiolucencies such that one element can be seen through the other in medical imaging.

Abstract: The invention relates to a device for providing skeletal support. A bone support device comprising an upright rod having a proximal and a distal end; at least one support member located near the proximal end for securing the rod to the bone; at least one distal anchoring element; and a vent member is provided.
