Patient-specific fracture-aiming instruments or custom instruments with removable patient-specific bone supports or other components, as well as patient-specific fixation plates, are provided in accordance with the present teachings and are described below.
In the context of the present teachings, patient-specific instrument components and implants are substantially configured to conform to the anatomy of a specific patient, and are formed substantially using computer-aided modeling based on the reconstructed three-dimensional anatomical image of the patient. The patient-specific instrument components have an engaging surface adapted to conformally contact and align a three-dimensional image / model of the patient's bone surface (with or without cartilage or other soft tissue) using the computer-aided imaging techniques described below. In this case, a patient-specific instrument component or implant nesting can match the bone surface (with or without articular cartilage) of a bone fragment or a directed fracture only in one position and thus emulate an intact bone of the specific patient. The patient-specific instrument components may include custom-made (custom) guide formations, such as suture holes, Kirschner wires, or for insertion of pins or other fasteners in configurations defined in a surgeon-approved preoperative plan.
The patient-specific components and other associated instruments and implants may be used preoperatively using computer-aided imaging techniques based on three-dimensional images of the patient's knee anatomy using magnetic resonance imaging, computed tomography, ultrasound, X-ray, or other three- or two-dimensional medical scans of the anatomy of the patient Patients are conceived and in some cases supplemented with digital photography procedures and / or anthropometry databases. Various CAD programs and / or software may be used to reconstruct a three-dimensional image, such as software used for Example of Materialize US, Plymouth, Michigan.
In the preoperative planning phase for directing and fixing a fracture, imaging data of the relevant anatomy of a patient in a medical facility or medical office can be obtained using one of the medical imaging methods described above. The imaging data may include, for example, various medical scans of a relevant portion of the anatomy of the patient required for creating a joint model, including images of all bone fragments, the major bone, and an equivalent intact bone, such as a right thigh bone, if a left thighbone is broken. An initial preoperative plan may be created for the patient in the imaging room and may include straightening bone fragments, selecting and fitting an implant, and designing patient-specific components, tools, and implants for the surgical procedure.

The present teachings provide various methods and apparatus for directing fractures and making an individual internal fixation for a specific patient and fracture. Various embodiments of custom-made instruments are in 2A - 3 and are described below. A computer illustration of a computerized preoperative plan is shown in FIG 1 and will be described below.
1 and 1A show a screen or a display 52 a computer terminal, laptop, tablet, smartphone, or other computing device having independent imaging software, or online, mobile, cloud, or other connectivity (including Ethernet, wired or wireless, Wi-Fi, 3G, 4G, etc.) for can provide the imaging software such as SurgiCase ® Connect, which is available from Materialize US, Plymouth, Michigan. Medical scans of the bone and bone fragments of a patient are transmitted via a data entry device or port 54 that with the computer device 50 is connected, entered, or otherwise uploaded, or accessed by the imaging software through a cloud, the Internet, or other secure connection.
Using the software, three- or two-dimensional images of the reconstructed bone and associated bone parts and fragments are viewed and manipulated on the screen 54 created during a preoperative planning for the specific patient. In 1 and 1A For example, images of bone sections are labeled with the same reference numerals as the patient's actual bone sections, but with the suffix "i" added for distinguishing purposes without having to repeat the "image of the bone section".
The present teachings are applicable to any bone, such as a femur, as in FIG 1 shown is a humerus, as in 1A is shown, or another bone. The same reference numbers will be used to denote different bone sections in each bone 80 regardless of whether it is a femur or humerus or any other bone. For example, in 1 the broken bone as a proximal femoral or hip bone 80i shown. In 1A is the broken bone as a humerus 80i shown. It should be noted that the Bone fragments are not necessarily to scale, and that in similar situations other types of surgical procedures may be indicated to the patient, such as: B. the complete or partial replacement of a joint. The bone fragments are shown only to illustrate the versatility of the instruments according to the present teachings and do not indicate a surgical plan for the patient who has suffered such a break.
At the in 1 example shown are first and second fragments 82i and 86i from the bone 80i canceled. The fragment 86i is (in whole or in part) of a neck section 88i of the bone 80i along a fractured surface 90i (or weakening range 90i ) and the fragment 82i is (in whole or in part) of a trochanteric segment 84i of the bone 80i along a fractured surface 92i (or weakening range 92i ) separated. The fragments 82i and 86i be on the screen 52 using an input device (keyboard, mouse, stylus or finger on touchscreens) until the fragments 82i . 86i in substantial contact with the counterparts 84i . 88i along the corresponding fracture surfaces 92i and 90i are brought. The bone 80i should appear essentially intact.
In some cases, a bone fragment may be missing (or unusable). In such cases, a patient-specific implant or a non-custom-made implant or filling material, depending on the location and size of the missing. Fragments, to be used. For example, a patient-specific implant 70i be provided to replace a corresponding missing bone fragment and on the underlying bone portion along an interface 72i , which is matched to a corresponding fracture surface, which in the illustration 1 With 72i matches. The patient-specific implant 70i can be designed by various methods, including, for example, extrapolating computationally from the existing bone fragments, selecting an implant from a database, and converting the selection using anthropometric data along with the patient's own data or creating a patient-specific implant 70i from the mirror-image bone of the patient, for example, using images of the intact left thighbone when the right thighbone is broken, or from images of the same bone that existed before the fracture occurred.
As continues in 1 If a small area of a bone is missing or weakened, a filling material may be used to fill the corresponding area, with a filling material insert 74i with a border 76i is formed, which is adapted to the remaining bone or bone fragment. The filling material may comprise inserts formed of bone, such as. As allografts, particles (bone chips, bone powder), osteomaterials, with or without porous metal or other frame-like structures, such. B.
