Medical image 1400 shows the advantages of using the embodiments of the present disclosure. A surgeon may use fluoroscopy or take a number of X-ray images during different stages of a surgical procedure. For example, before deploying fasteners 710 in one or both of the bone attachment feature 908 and the bone attachment feature 910, a surgeon may take an X-ray to confirm that the resection guide 820c is a desired position relative to the bones and/or a joint. In addition, further use of fluoroscopy and/or capturing additional X-ray images can produce the medical image 1400 of FIG. 14.

Conventionally, correction methods, systems, and/or instrumentation for a condition such as, for example, a bunion and/or a hallux valgus, face several challenges. One example is how to cut the bone such that the cut faces have a desired angle in relation to each other. Advantageously, the present disclosure can address many, if not all, of these challenges to assist a surgeon in performing the surgical procedure and improve the quality of patient care and outcomes.

Advantageously, because the present disclosure uses a bone model of the patient’s bones the sizes, dimensions, lengths and configurations of the components of the example systems can each be changed, adapted, revised, and/or customized to meet the needs and/or preferences of the patient and/or surgeon. Advantageously, using the apparatus, systems, and/or methods of the present disclosure the surgeon may have a preoperative plan that identifies which specific bone screw (length, width, diameter, thread, pitch, etc.) to use for the fasteners.

Those of skill in the art will appreciate that embodiments of the system disclosed herein can be used on humans and on bones that are relatively small in comparison to other bones of the body (e.g., bones of the foot and hand). Advantageously, the embodiments of the system seek to minimize the number of fasteners or pins placed within the bones of a patient by planning a surgical procedure such that pins or fasteners placed in one stage are and/or can be reused in subsequent stages. Consequently, pins initially deployed can remain in the bone or bone fragment as instruments are deployed and/or subsequent stages of the surgical procedure are performed.

Alternatively, or in addition, these check can assist a surgeon in positioning and/or registering the resection guide 820c to one or more bones and/or to a position that matches the position planned in a preoperative plan 506. Such position and registration checks can help a surgeon to complete the surgical procedure in the manner desired and prior to finalizing a position of the resection guide 820c and initiating one or more osteotomies.

For example, a surgeon may visually check, using medical image 1400, that the proximal resection feature 902 extends from medial to lateral on a trajectory that is perpendicular to a longitudinal axis of the second metatarsal 210. Alternatively, or in addition, a surgeon may check (e.g., visually) that the distal resection feature 904 extends from medial to lateral on a trajectory that is perpendicular to a longitudinal axis of the first metatarsal 208 (e.g., when the first metatarsal 208 is in a deformed position). Alternatively, or in addition, a surgeon may check (e.g., visually) that an arm and holes 940 of a proximal bone attachment feature 908 extend from the body 900 proximal to distal on a trajectory that is parallel to a longitudinal axis of the second metatarsal 210. Further, the surgical procedure may check (e.g., visually) that the arm and holes 940 of the proximal bone attachment feature 908 will align from proximal to distal with an arm and holes 940 of the distal bone attachment feature 910 postoperatively once the osteotomies are completed and the first metatarsal 208 is brought in contact with the medial cuneiform 202 during reduction. Such visual checks at one or more stages of a surgical procedure may assist a surgeon in validating that the preoperative plan 506 is the plan to continue and may provide assurance that osteotomies formed using the resection guide 820c will be in and where the surgeon desires to form them.

In one example, before deploying fasteners 710, as appears to have been done before capturing medical image 1400, a surgeon may initially position the resection guide 820c in the position shown in medical image 1400. Once in this position, a surgeon may review multiple landmarks of the bones and/or structures of the patient in relation to one or more structures of the resection guide 820c.

At any stage of a surgical procedure, a surgeon can use fluoroscopy or take a number of X-ray images to confirm and/or validate a preoperative plan 506 and/or to confirm that steps have been taken and proceed according to the surgeon’s plan. In one example preoperative plan 506, a surgeon may have virtually repositioned a bone model of the first metatarsal 208 from a deformed orientation to a desired orientation (e.g., such that a longitudinal axis of the first metatarsal 208 will be parallel or substantially parallel to a longitudinal axis of the second metatarsal 210, IM angle of about 0). Based on a preoperative plan 506 that includes such a correction for the first metatarsal 208, the surgeon next may use an image like medical image 1400 to check a number of other characteristics of the resection guide 820c.

With the resection(s) completed, the resection guide can be removed and one or more fasteners 710 retained in one or more bones. The retained fasteners may be used to translate and/or rotate the proximal and distal bone or bone fragments. In one embodiment, a compressor or distractor can be deployed over the fasteners 710 to facilitate joining, translating, holding, and/or positioning the cut surfaces and/or fusing the bones. Those of skill in the art will appreciate that for certain patients with certain pathologies, the form and/or shape of the resection guide can be different. As explained above, the resection guide can be positioned, sized, configured, and oriented and/or trajectories set for the resection guide preoperatively using bone models. Additionally, a surgeon can provide a prescription for the location of guide features (e.g., resection features) to account for other conditions of a particular patient. Those of skill in the art will appreciate that the resection guide can be used for a variety of procedures in a hindfoot, midfoot, forefoot, hand, wrist, elbow, shoulder, and/or the like. One skilled in the art can appreciate that the presented embodiments may be modified, revised, or repositioned to address a surgeon’s particular angles, approach, entry locations and/or preferences.

Medical image 1400 shows a landmark registration features 1004 that extends distally and engages a lateral side of a base of the first metatarsal 208. In addition, in the example embodiment, the markings 970 extend from a superior side 914 to an inferior side 916. This enables the markings 970 to show clearly when using X-rays for the medical image 1400.

Medical image 1400 shows clearly where the proximal resection feature 902 and distal resection feature 904 are in relation to each other and in relation to the bones of the patient. Advantageously, a surgeon can see the distal end of the medial cuneiform 202 and the proximal end of the first metatarsal 208 by way of the window 906. This visual indicator for the surgeon can provide clarity that osteotomies formed using the resection features are in the desired positions and/or angles relative to the bones in a preoperative condition. If a surgeon determines that something is not as planned or as needed, the surgeon can alter the surgical procedure to account for this.

In the illustrated embodiment, the medical image is a dorsoplantar projection/view using an X-ray or a fluoroscopy device. In one embodiment, the medical image 1400 shows bones of a patient and a resection guide 820c positioned on a dorsal side of the bones at a stage of a surgical procedure. At this stage, a surgeon has created an incision and taken steps to permit an inferior side 916 of the resection guide 820c to rest on a dorsal surface of the medial cuneiform 202 and the first metatarsal 208. The surgeon appears to have deployed a fastener 710 in a distal hole 940 of the bone attachment feature 910 and deployed a fastener 710 in a proximal hole 940 of the bone attachment feature 908.
