Abstract: Provided is an elbow joint prosthetic implant (100) comprising: a humeral component (50) comprising a humeral stem portion (60) configured for placement within the humeral intramedullary canal of a subject, an ulnar component (110) comprising an ulnar stem portion (120) configured for placement within the ulnar intramedullary canal of the subject, wherein the humeral component (50) and ulnar component (110) are connected by an implant elbow joint (130), wherein the ulnar component (110) further comprises an angulation joint (140) that is separate from the implant elbow joint (130), wherein the angulation joint (140) and has at least one degree of freedom of rotational movement configured to adjust and fix a varus-valgus direction of the ulnar stem portion (120).

Abstract: A robotic system is provided for assisting during bone surgery, adapted to control the position of a limb. The robotic system includes a robotic arm connected to a fixation device for rigidly connecting the distal bone to the robotic arm and allowing movement in six degrees of freedom. Specifically, the fixation device provides at least two fixation points to the distal bone. The first fixation point can be rigidly connected to the distal bone near the joint and the second fixation point can be rigidly connected to a distal position of the distal bone. The rigid connection of the distal bone to the robotic arm allows the robotic system to impose controlled movement on the distal bone in six degrees of freedom.

Abstract: A bone cutting system includes an elongated surgical bone cutting tool having a first extremity for fixing the bone cutting tool to a cutting robot or machinery and a second extremity opposite thereto at the end of the elongated surgical bone cutting tool. The protection system comprises a protection element attachable to the elongated bone cutting tool. The protection element includes an interposing portion covering, when the protection element is attached to the elongated cutting tool, at least the second extremity of the elongated cutting tool, so that the interposing portion is being interposed between the soft tissue and the bone cutting tool during cutting with the elongated cutting tool, for preventing the bone cutting tool from cutting into the soft tissue. During cutting with the bone cutting tool, the protection element follows in congruence with the bone cutting tool.
