The present invention discloses a prosthetic device for reconstruction of sternum, ribs, and clavicles, comprising a manubrium plate attached to a sternum plate by means of a joining plate. The manubrium plate has spherical ends coupled to the clavicle plate by screwing into a cup lock. The manubrium plate has extensions with holes, on which rib plates are seated. Similarly, the sternum plate has extensions with holes, on which rib plates are seated.

The present invention provides a method for generating a bone fixation implant and related preoperative planning. The method comprises a first step of determining at least the orientation and the position of the fixation means, based on a 3D model of the bone fragments. The method may include a second step of defining the shape of one or more bone plates, based on the output of the first step. The method may further include a third step determining tools for applying fixation means during surgery, according the optimized configuration defined in the first step and applying the bone plates from the second step. The method may even further include a fourth step, quantifying construct stability for a given patient following surgery, thereby allowing early weightbearing.

In one aspect, an implant configured to attach a first bone section to a second bone section comprises an intramedullary portion and an extramedullary portion. The intramedullary portion is configured for insertion into the first bone section. The ex-tramedullary portion is configured to abut a surface of the second bone section and includes a first fastener aperture configured to eceive a bone fastener inserted in the second bone section. The intramedullary portion and the extramedullary portion are coupled such that the extramedullary portion is rotatable with respect to the intramedullary portion.

A surgical kit and a method for performing osteotomy is disclosed. The surgical kit comprises at least two lateral plates and a central plate. The two lateral plates are scaled and fixed over a surgical bone adjacent to each other with an exact distance measured by the scaled lateral plates while the central plate is over two lateral plates to maintain the alignment. The distance is equal to the shortening amount of bone based on the pre-operative measurements. The central plate slides laterally over the two lateral plates to expose the surgical site of the bone. Shortening osteotomy is performed to shorten the bone equal to the distance between the two lateral plates. The central plate then laterally slides over the two lateral plates to achieve the anatomic alignment. Further, the central plate and the two lateral plates are securely fixed to the bone using one or more fasteners.

A surgical planning and evaluation method may include receiving an image of a patient's anatomy before a surgery and generating a surgical plan for performing the surgery. The surgical plan may include a planned surgical result. The method may include receiving an image of the patient's anatomy after surgery. The image may include data representing the achieved surgical result. The method may include digitally comparing the planned surgical result with the achieved surgical result and generating a quantification the surgical result based on the digital comparison.

A joint stabilization (reduction) system and associated methods and tools for placement of the system in an open or minimally invasive technique. The joint stabilization system includes a flexible prosthetic band for stabilizing the bones in proper position and a connector mechanism for joining the two ends of the prosthetic band around the bones. One end of the prosthetic band can be permanently attached to the connector.

A bone positioning guide may include a main body member, a shaft, and a bone engagement member. The shaft can be movably connected to the main body member and have the bone engagement member rotatably coupled to its distal end. The bone engagement member can have a surface configured to engage a bone. The main body member can also include a tip opposite the bone engagement member for engaging a second bone. In use, the bone engagement member may be positioned in contact with a medial side of a first metatarsal while the tip is positioned in contact with a lateral side of a different metatarsal, such as a second metatarsal. The shaft can then be moved to advance the bone engagement member toward the tip, causing realignment of the first metatarsal.

An implant assembly for use in tissue repairs includes a fixation device and a flexible elongate implant. The fixation device has a body with a first surface adapted to face towards a bone and a second surface adapted to face away from the bone. Apertures extend through the fixation device body from the first surface to the second surface and serve to attach one end of the flexible elongate implant loop. The flexible elongate implant has a multifilament structure comprising filaments which are of a metallic or non-metallic material. The implant is coupled to the fixation device by passing through the apertures, and has a loop having a first end that is secured to the fixation device and a second end which can be releasably coupled to the fixation device following passage through or around a bone, for securing the implant assembly relative to the bone.

Systems, assemblies, and methods are provided herein for fastening of one bone to another bone using one or more sutures. The features herein enable such fastening with a more accurate strength, and which can be more easily fastened in-situ.
