Abstract: A computer-implemented bone-implant system evaluation method for application of mesh-free analysis of a bone-implant system for evaluation of performance of a bone-implant system for an implant implanted within the bone structure at an anatomical site, said method comprising (i) receiving a set of bone structure data set, wherein set of bone structure data includes data indicative of the bone structure at an anatomical site; (ii) inputting an implant data set and inputting the position of the implant data set, wherein the implant is selected based upon the biomechanical requirements for the anatomical site and the position and of the implant data set is indicative of the position of the implant with respect to the anatomical site, wherein implant data set includes data representative of the geometry and materials properties of the implant; (iii) creating a bone-implant model, wherein said bone implant-model includes a mesh-free model of trabecular bone at the anatomical site wherein the bone-implant model is

Abstract: A fixation system (900) for the fixation of a first bone fragment (932) relative to a second bone fragment (934); the fixation system (900) comprising at least one first bone engagement element engagable with the first bone fragment (932), wherein the first bone engagement element has an elongate body portion, a proximal end, a distal end, and a passageway extending through the body portion from the proximal end to the distal end, at least one further bone engagement element engageable with the second bone fragment (934) and having a tensile element (920) securement portion for affixing a tensile element (920) to the further bone engagement element; wherein the tensile element (920) passing the first bone engagement element when engaged with the first bone fragment (932) is fixed relative to the further bone engagement element when engaged with the second bone fragment (934) by the tensile element (920) securement portion; such that the first bone fragment (932) is affixed relative to the second bone fragment

Abstract: An implant device (A1) for engagement with a bone of a patient, the implant device (A1) comprising a distal end (B1), a proximal end (C1), a central shaft (D1) extending therebetween and a longitudinal central axis (E1); the implant device (A1) further including a helical thread portion (F1) extending circumferentially about the central shaft (D1) and extending from the distal end (B1) towards the proximal end (C1) thereof, and a root (G1) at the base of the helical thread portion (F1) adjacent the central shaft (D1), the helical thread portion (F1) including a leading edge (H1) and a trailing edge (I1) both extending at least radially outwardly from the central shaft (D1) and defining the thread portion (F1) therebetween, with the root (G1) of the thread portion (F1) defined therebetween in a direction of the longitudinal central axis (E1) of the implant device (A1); wherein the leading edge (H1) faces in a direction of at least towards the distal end (B1) of the implant device (A1), and the trailing edge (I

Abstract: Devices and methods for the removal of bone implant tips from within a bony structure in a body. The device or method includes a shaft with an internal grasping feature capable of being inserted while remaining in an un-expanded, un-deployed state. This permits a surgeon or operator to insert the device while in a small profile state, avoiding or reducing damage to adjacent bone tissue during insertion. Upon insertion of the shaft to the proper position within a patient's bone, the grasping feature may then be expanded or deployed from the distal end of the shaft by a surgeon or operator using an actuator in a handle attached to the proximal end of the shaft. Following deployment, the grasping feature may be used to manipulate and/or remove a bone implant tip from a patient's bone tissue. Embodiments of the grasping feature include one or more hooks, wires, articulating fingers, and/or net-based designs formed of metal, polymer, composite, or a combination thereof.
