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: Diagnostic systems and methods for measuring and assessing spine instability are described which involve reconstruction of a dynamic three-dimensional model of a patient's spine moving through a range of motions, and optimization of the three-dimensional model to provide relative three-dimensional position and orientation data for each vertebra in the spine throughout the motion. Vertebral movement is thereby accurately measured and instability determined for presentation in a user-friendly form.

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.

Abstract: A bone screw having a threaded shaft 15 which has a thread having an outer diameter DA, a frontal thread end and a thread profile. The thread profile has a frontal thread flank which is directed towards the frontal thread end 4, a rear thread flank 18 and a flank angle ?. The thread is multipath, preferably a double path thread where each thread path has a blade-type element with a cutting edge on the frontal thread end. The bone screw 1 also has a longitudinal axis 2. For accommodating a guide wire, the bone screw 1 is provided with a central borehole 9, which is coaxial with its longitudinal axis 2.

Abstract: The invention relates to a device for fixing bones, comprising: A) an intramedullary nail (1) having at least one cross hole (2) with a central axis (3), and; B) a bone fixation means (4) with a front end (6) and with a rear end (5) that is intended for inserting into the cross hole (2) of the intramedullary nail (1), whereby; C) the bone fixation means (4) can be elastically expanded.

Abstract: The invention relates to a device for bone fixation, comprising A) an intramedullary pin (1) having a longitudinal axis (17), a distal tip (2) for introduction into the marrow cavity, and a proximal rear end (3) and B) a bone plate (10), for location on the greater trochanter, arranged at the proximal rear end (3) of the pin (1), whereby C) the pin (1) has a through transverse drilling (6) in the proximal half (7) thereof which faces the proximal rear end (3), for housing a hip screw (30) and D) the bone plate (10) terminates proximally above the transverse drilling (6).

Abstract: The invention relates to a bone screw having a longitudinal axis and a threaded shaft which has an external thread of an external diameter DA, a front thread end and a thread profile. The thread profile has a front thread flank that is oriented towards the front thread end. The front thread flank comprises a flank section that has a 90° offset in relation to the front thread flank, thereby forming a tangential cutting edge on the front thread end.
