DETAILED DESCRIPTION

[0041] Various embodiments are described more fully below with reference to the accompanying drawings, which form a part hereof, and which show specific exemplary embodiments. However, the concepts of the present disclosure may be implemented in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided as part of a thorough and complete disclosure, to fully convey the scope of the concepts, techniques and implementations of the present disclosure to those skilled in the art. Embodiments may be practiced as methods, systems or devices. The following detailed description is, therefore, not to be taken in a limiting sense.

[0042] Reference in the specification to one embodiment or to an embodiment means that a particular feature, structure, or characteristic described in connection with the embodiments is included in at least one example implementation or technique in accordance with the present disclosure. The appearances of the phrase in one embodiment in various places in the specification are not necessarily all referring to the same embodiment. The appearances of the phrase in some embodiments in various places in the specification are not necessarily all referring to the same embodiments.

[0043] In addition, the language used in the specification has been principally selected for readability and instructional purposes and may not have been selected to delineate or circumscribe the disclosed subject matter. Accordingly, the present disclosure is intended to be illustrative, and not limiting, of the scope of the concepts discussed herein.

[0044] The embodiments described herein provide novel self-aligning plating systems and methods. The disclosed systems may include an interbody spacer, a medical device plate, and an insertion member. In use, the interbody spacer is configured to be inserted between two portions of a patient's anatomy, such as between adjacent vertebrae of the patient's spinal column. This interbody spacer essentially serves as an alignment tool, onto which the medical device plate is positioned to contact the anatomy portion(s).

[0045] FIG. 1A illustrates an exploded view a self-aligning plating system 100 in accordance with one embodiment. As seen in FIG. 1A, the self-aligning plating system 100 may include an interbody spacer 102, a medical device plate 104, an insertion member 106, and an optional extension member 108 to operably engage the insertion member 106 during alignment/insertion. FIG. 1B illustrates the components of the self-aligning plating system 100 of FIG. 1A in contact with each other such as during placement of the interbody spacer 102 and the medical device plate 104.

[0046] The interbody spacer 102 may be made of plastic and include or otherwise be configured with a first gendered coupling mechanism, and the insertion member 106 may include or otherwise be configured with a second gendered coupling mechanism such that the interbody spacer 102 and the insertion member 106 can operably engage each other. The interbody spacer 102 may be a ceramic, metal, autograft, or allograft spacer in some embodiments. In some embodiments, the first gendered coupling mechanism may be a female coupling mechanism and the second gendered coupling mechanism may be a male coupling mechanism. In some embodiments, the first gendered coupling mechanism may be a male coupling mechanism and the second gendered coupling mechanism may be a female coupling mechanism. The exact configurations of the first and second gendered coupling mechanisms may vary as long as the interbody spacer 102 and the insertion member 106 can operably engage each other to accomplish the objectives of the embodiments described herein.

[0047] During placement, the interbody spacer 102 may be inserted between two portions of a patient's anatomy such as between a top and bottom vertebra. This placement may be facilitated by the insertion member via engagement between the above-discussed first and second gendered coupling mechanisms. The medical device plate 104 may then be positioned at one end of the insertion member 106, and slid over the insertion member 106 to eventually come into contact with the interbody spacer 102 and the patient anatomy portion(s).

[0048] The configuration of the interbody spacer 102, the medical device plate 104, and the insertion member 106 may vary as long as a surgeon can properly position the required components with respect to the patient's anatomy. For example, the medical device plate 104 may be configured with one or more hexagonal-shaped holes, and the insertion member 106 may include a hexagonal-shaped perimeter such that the medical device plate 104 can slide over the perimeter of the insertion member 106 to contact the interbody spacer 102.

[0049] FIGS. 2A-2D illustrate multiple views of an interbody spacer 202 in accordance with one embodiment. The interbody spacer 202 may be similar to the interbody spacer 102 of FIGS. 1A-1B, for example.

[0050] FIGS. 2A-2B illustrate perspective and top views of the interbody spacer 202, respectively. FIG. 2C illustrates a cross-sectional view of the interbody spacer 202 and FIG. 2D illustrates a front view of the interbody spacer 202. As seen in FIGS. 2A-2D, the interbody spacer 202 includes an alignment hole 204 to assist in aligning a plate such as the medical device plate 104 of FIGS. 1A-1B.

[0051] The alignment hole 204 may serve as a female coupling mechanism such that it can receive a male coupling mechanism of the insertion member 106. The alignment hole 204 may be formed of a plurality of threads such that it can receive a screw with threaded portions, for example.

[0052] FIGS. 3A-3B illustrate a medical device plate 302 in accordance with one embodiment. As seen in FIGS. 3A-3B, the medical device plate 302 may include one or more alignment holes 304. In this particular embodiment, the alignment hole(s) 304 on the medical device plate 302 are hexagonal-shaped. The exact shape and size of the alignment hole(s) 304 on the plate 302 may vary as long they can receive the insertion member and operably connect to the interbody spacer for proper alignment with respect to the interbody spacer 102 and patient anatomy.

[0053] The plate may further include lines, groves, or some other indicia to indicate and achieve proper alignment. Once properly aligned with the interbody spacer, the medical device plate may be secured to the patient using any suitable technique(s).

[0054] In operation, and with reference to FIGS. 1A & 1B, a surgeon may place the interbody spacer 102 at an appropriate position with respect to a patient's anatomy. If the surgeon hadn't previously done so, he or she may then operably connect the insertion member 106 with the interbody spacer 102 (e.g., into an alignment hole of the interbody spacer 102 such as the alignment hole 204 of FIGS. 2A-2D).

[0055] Once the insertion member 106 is operably connected with the interbody spacer 102, the surgeon may place the medical device plate 104 on the insertion member 106 such that the insertion member 106 can then pass through a hole of the medical device plate 104. The surgeon may then slide the medical device plate 104 along the length of the insertion member 106 until it comes into contact with the patient's anatomy (e.g., adjacent vertebrae) and the interbody spacer 102. The medical device plate 104 would therefore be properly aligned with respect to the patient's anatomy in the correct coronal, axial, and sagittal orientations.

[0056] The insertion member 106 may serve as a temporary fixation of the plate to the patient's anatomy, such as before the medical device plate 104 is secured to the patient. This alignment can also be used for other surgical or medical templates/guides. For example, the insertion member 106 may be used to deliver organic and/or inorganic bone void/bone grafting materials or extenders.

[0057] FIG. 4 illustrates a self-aligning plating system 400 secured to a patient in accordance with one embodiment. In this embodiment, an interbody spacer 402 is positioned between a top vertebra 404 and a bottom vertebra 406 of a patient's anatomy. A medical device plate 408 that includes a hexagonal-shaped hole has been slid over an insertion member 410 to come into contact with the interbody spacer 402, the top vertebra 404, and the bottom vertebra 406. The medical device plate 408 has been secured to the top and bottom vertebra 404 and 406, respectively, by a plurality of screws 412. Once the medical device plate 408 is secured, the insertion member 410 may be detached from the interbody spacer 402.

[0058] Although only two vertebra are shown in FIG. 4, the medical device plate 408 may contact more than two vertebra. For example, there may be two interbody spacers operably positioned with respect to a patient's anatomy, such as a first interbody spacer positioned between a top vertebra and a middle vertebra, and a second interbody spacer positioned between the middle vertebra and a bottom vertebra. In this scenario, a medical device plate may contact each interbody spacer to fixate a plurality of vertebra.

[0059] In some embodiments, when the insertion member 410 is removed from the medical device plate 408, a hole 414 in the medical device plate 408 may be exposed. Once the hole 408 is exposed, the plate 410 may be secured to at least one vertebra or the interbody spacer 402. The medical device plate 408 may be secured with a screw, stake, nail, or other fixture in some embodiments.

[0060] FIG. 5 illustrates another embodiment in which the insertion member 502 is configured as a standalone component. FIG. 6 illustrates the insertion member 502 of FIG. 5 in accordance with one embodiment. Once the medical device plate has been secured to the patient, the surgeon may apply pressure to squeeze the insertion member 502 to disengage and detach the insertion member 502 from the patient (and the interbody spacer). In some embodiments, the insertion member 502 may be passively attached and detached from the interbody spacer. In some embodiments, the insertion member 502 may be actively attached and detached from the interbody spacer. For example, the insertion member 502 may be pinched to remove the insertion member from the interbody spacer.

[0061] FIG. 7 depicts a flowchart of a method 700 for attaching a medical device plate and interbody spacer to a spinal column in accordance with one embodiment. Step 702 involves inserting an interbody spacer between adjacent vertebrae of the spinal column. The interbody spacer of step 702 may be similar to the interbody spacer 102 of FIG. 1 and have a first gendered coupling mechanism.

[0062] Step 704 involves operably connecting an insertion member to the interbody spacer, the insertion member having a second gendered coupling mechanism. The gender of the first gendered coupling mechanism is the opposite gender of the second gendered coupling mechanism.

[0063] Step 706 involves sliding the medical device plate along the insertion member to position the medical device plate over the interbody spacer. The medical device plate may be similar to the medical device plate 104 of FIG. 1 and include at least one hole or aperture to slide along the length of the insertion member 106. The medical device plate may slide along the insertion member 106 until it comes into contact with the patient's anatomy.

[0064] Step 708 involves aligning the medical device plate at the adjacent vertebrae. By virtue of its sliding along the insertion member and coming into contact with the patient's anatomy, the medical device plate may be properly aligned with the patient's anatomy.

[0065] Step 710 involves attaching the medical device plate to the adjacent vertebrae. The medical device plate may be secured to the patient's anatomy via one or more screws, for example.

[0066] Step 712 involves detaching the insertion member from the interbody spacer. Once the medical device plate is properly secured to patient's anatomy, the insertion member may be removed from the interbody spacer.

[0067] In some embodiments, the medical device plate and the spacer may be attached to bone elements other than a spinal column. For example, the medical device plate and an interosseus spacer may be attached to fixate two bone elements of a broken bone.

[0068] The methods, systems, and devices discussed above are examples. Various configurations may omit, substitute, or add various procedures or components as appropriate. For instance, in alternative configurations, the methods may be performed in an order different from that described, and that various steps may be added, omitted, or combined. Also, features described with respect to certain configurations may be combined in various other configurations. Different aspects and elements of the configurations may be combined in a similar manner. Also, technology evolves and, thus, many of the elements are examples and do not limit the scope of the disclosure or claims.

[0069] Embodiments of the present disclosure, for example, are described above with reference to block diagrams and/or operational illustrations of methods, systems, and devices according to embodiments of the present disclosure. The functions/acts noted in the blocks may occur out of the order as shown in any flowchart. For example, two blocks shown in succession may in fact be executed substantially concurrent or the blocks may sometimes be executed in the reverse order, depending upon the functionality/acts involved. Additionally, or alternatively, not all of the blocks shown in any flowchart need to be performed and/or executed. For example, if a given flowchart has five blocks containing functions/acts, it may be the case that only three of the five blocks are performed and/or executed. In this example, any of the three of the five blocks may be performed and/or executed.

[0070] A statement that a value exceeds (or is more than) a first threshold value is equivalent to a statement that the value meets or exceeds a second threshold value that is slightly greater than the first threshold value, e.g., the second threshold value being one value higher than the first threshold value in the resolution of a relevant system. A statement that a value is less than (or is within) a first threshold value is equivalent to a statement that the value is less than or equal to a second threshold value that is slightly lower than the first threshold value, e.g., the second threshold value being one value lower than the first threshold value in the resolution of the relevant system.

[0071] Specific details are given in the description to provide a thorough understanding of example configurations (including implementations). However, configurations may be practiced without these specific details. For example, well-known circuits, processes, algorithms, structures, and techniques have been shown without unnecessary detail in order to avoid obscuring the configurations. This description provides example configurations only, and does not limit the scope, applicability, or configurations of the claims. Rather, the preceding description of the configurations will provide those skilled in the art with an enabling description for implementing described techniques. Various changes may be made in the function and arrangement of elements without departing from the spirit or scope of the disclosure.

[0072] Having described several example configurations, various modifications, alternative constructions, and equivalents may be used without departing from the spirit of the disclosure. For example, the above elements may be components of a larger system, wherein other rules may take precedence over or otherwise modify the application of various implementations or techniques of the present disclosure. Also, a number of steps may be undertaken before, during, or after the above elements are considered.

[0073] Having been provided with the description and illustration of the present application, one skilled in the art may envision variations, modifications, and alternate embodiments falling within the general inventive concept discussed in this application that do not depart from the scope of the following claims.
