A method of repairing a fractured bone may include implanting a prosthetic stem into an intramedullary canal of the fractured bone. First and second bone segments of the fractured bone may be robotically machined to include first and second implant-facing surfaces that are substantially negatives of first and second surface portions of the first end of the prosthetic stem. The first and second tuberosities may be machined so that the first and second bone segments have first and second interlocking surfaces shaped to interlock with each other. During implantation, the first and second implant-facing surfaces are in contact with the first and second surface portions of the first end of the prosthetic stem, and the first interlocking surface interlocks with the second interlocking surface.

A clamp assembly for orthopedic use having a housing that includes a top surface, a recess, a distal base and a bottom surface, the recess defining a longitudinal axis and extending through the housing from the top surface through the distal base and toward the bottom surface, and at least two through slots, each one of being disposed at a bottom or a side a surface of the housing. The assembly including a securement assembly positionable within the recess in a co-axial relationship to a mating surface on the recess, and a band sized for travel along a predetermined path defined in part by the through slots in the housing, wherein at least one of the through slots is a starting point for travel of the band along the predetermined path.

An improved fracture cabling system has one or more spacers. Each spacer has a longitudinal length extending along a body of the spacer. The body has an upper portion with an aperture configured to receive a wire or cable and a lower portion having one or more pairs of feet spaced by a longitudinal gap or groove. Each of the one or more pairs of feet is located on a lateral side of the spacer body and configured to contact a bone with a fracture. The gap is configured to be positioned over the fracture with each foot positioned on a side of the bone spaced from the fracture. The longitudinal length of the one or more spacers is preferably curved or arcuate. Each body of the one or more spacers has a leading end and a trailing end.

Disclosed herein is an implant for bone fixation comprising an elongated member configured to be wound around bone parts that are to be fixed, an engagement member coupled to the elongated member and configured to engage a portion of the elongated member so as to secure the implant in a loop around the bone parts, and a fastening member arranged between and coupled to the elongated member and the engagement member. The fastening member comprises at least two separate pieces each comprising one opening for receiving a bone fastener, wherein the separate pieces are coupled to each other by a material having a lower material strength than a material from which the separate pieces are made.

A measuring instrument configured to measure a bone and a plate to determine the size of an attachment clamp, including: a medial clamp configured to engage a medial portion of the bone; a medial gauge connected to the medial clamp, the medial gauge including: a key along a portion of the medial gauge adjacent the medial clamp; a gauge indicator configured to indicate the size of attachment clamp; and a threaded portion; a lateral clamp configured to engage a plate on the bone, where the lateral clamp has a hollow portion with a channel, wherein the gauge indicator is positioned in the hollow portion and wherein the channel is configured to engage the key of the gauge indicator to prevent the lateral clamp from rotating about the gauge indicator; and a tightening knob threaded onto the thread portion of the of the medial gauge, wherein one end of the tightening knob indicates on the gauge indicator the size of the attachment clamp.

The various embodiments disclosed herein relate to bone fixation or fusion devices, including intramedullary fixation or fusion devices that are implanted around the target bone. Certain device embodiments relates to devices that can be bent or otherwise deformed to replicate the natural or desired curve of the bone or joint being treated. In addition, other embodiments relate to implantation devices that can be used to implant or position the bone fixation or fusion devices.

The invention is a solution for osteosynthesis made with molded metal sheets joined vertically and horizontally, fitted to the shape and dimensions of the fractured bone to keep it immobile and united. For the orthosis, it depicts metal sheets joined with horizontal and vertical movements, molded to the form and dimensions of vertebrae and joints to keep them separated. The sheet metals have wavy shapes, channels and undulations that give consistency and structural strength to bending, tension, shear and bends for joints. It also describes the process for the osteosynthesis with metal sheets and 3D printing, where the surgeon wraps the osteosynthesis or molded orthosis around the bone, vertebrae or joint, fastening it with clamps that tighten and lock with a surgical instrument, without screws. The sheet metals have viewpoint holes to see through during surgery and subsequent control with Roentgen. The clamps are in channels, which have micro-points on the side contacting the bone.
