1. Field of the Invention
The present invention relates generally to orthopedic treatments, and more particularly, but not by way of limitation, to devices, apparatuses, kits, and methods for repairing and/or augmenting the articular surface and/or articular rim of a joint.
2. Description of Related Art
One example of a method for repairing (e.g., after a fracture resulting from an anterior shoulder dislocation) the rim of a patient's glenoid (glenoid fossa) is known as the Laterjet procedure, in which a portion of a patient's coracoid process is removed and attached to the clavicle in a position where a portion of the glenoid rim has previously broken off, to augment the anterior glenoid and stabilize the humeral head in the shoulder joint. Fitting the removed portion of the coracoid process to the anterior glenoid rim involves a trial-and-error approach that requires a surgeon (or other healthcare provider) to iteratively shape the removed portion of the coracoid process to the anterior glenoid to augment the glenoid rim without interfering with motion of the joint. This trial-and-error approach may, in some instances, be complicated by variations in coracoid shape.
This disclosure includes embodiments of devices, apparatuses, kits, and methods for repairing and/or augmenting the articular surface and/or articular rim of a joint.

Any embodiment of any of the present devices, apparatuses, kits, and methods can consist of or consist essentially of—rather than comprise/include/contain/have—any of the described steps, elements, and/or features. Thus, in any of the claims, the term “consisting of” or “consisting essentially of” can be substituted for any of the open-ended linking verbs recited above, in order to change the scope of a given claim from what it would otherwise be using the open-ended linking verb.
Details associated with the embodiments described above and others are presented below.
The following drawings illustrate by way of example and not limitation. For the sake of brevity and clarity, every feature of a given structure is not always labeled in every figure in which that structure appears. Identical reference numbers do not necessarily indicate an identical structure. Rather, the same reference number may be used to indicate a similar feature or a feature with similar functionality, as may non-identical reference numbers. The figures are drawn to scale (unless otherwise noted), meaning the sizes of the depicted elements are accurate relative to each other for at least the embodiments depicted in the figures.
The term “coupled” is defined as connected, although not necessarily directly, and not necessarily mechanically; two items that are “coupled” may be unitary with each other. The terms “a” and “an” are defined as one or more unless this disclosure explicitly requires otherwise. The term “substantially” is defined as largely but not necessarily wholly what is specified (and includes what is specified; e.g., substantially 90 degrees includes 90 degrees, and substantially parallel includes parallel), as understood by a person of ordinary skill in the art. In any embodiment of the present devices, apparatuses, kits, and methods, the term “substantially” may be substituted with “within [a percentage] of” what is specified, where the percentage includes 0.1, 1, 5, and/or 10 percent.
The terms “comprise” (and any form of comprise, such as “comprises” and “comprising”), “have” (and any form of have, such as “has” and “having”), “include” (and any form of include, such as “includes” and “including”) and “contain” (and any form of contain, such as “contains” and “containing”) are open-ended linking verbs. As a result, an apparatus or kit that “comprises,” “has,” “includes” or “contains” one or more elements possesses those one or more elements, but is not limited to possessing only those elements. Likewise, a method that “comprises,” “has,” “includes” or “contains” one or more steps possesses those one or more steps, but is not limited to possessing only those one or more steps.
Further, an apparatus, device, or structure that is configured in a certain way is configured in at least that way, but it can also be configured in other ways than those specifically described.

In some embodiments, body 14 is configured to be coupled to the bone by one or more screws (e.g., screws 500 of
In some embodiments, body 14 comprises a plurality of projections extending outwardly from coupling side 18 and configured to resist movement of the body relative to the bone. For example, in the embodiment shown, body 14 comprises a plurality of (e.g., conical) spikes 42 configured to extend into the bone adjacent a joint socket when body 14 is coupled to the bone. In other embodiments, projections have any suitable other shape that resists lateral movement of body 14 relative to bone (e.g., in a direction parallel to coupling side 18). In some embodiments, coupling side 18 is configured to permit bone ingrowth into body 14 (e.g., inwardly relative to at least one portion of coupling side 18, such that ingrown bone will resist lateral movement of body 14 relative to the bone. For example, in the embodiment shown, coupling side 18 comprises a plurality of open channels 46 extending parallel to coupling side 18. In other embodiments, coupling side 18 can comprise any suitable features configured to permit bone ingrowth into body 14. For example, in some embodiments, coupling side 18 can be textured (e.g., at least a portion of the coupling side can be at least one of porous and etched). In most embodiments, concave side 22 is substantially smooth (e.g., polished or otherwise devoid of surface irregularities that might otherwise interfere with joint motion when body is coupled to a bone such that concave surface 22 augments the articular surface of the joint).
Body 14 can comprise one or more of a variety of non-biological materials (not harvested from a human patient or other animal). For example, body 14 can comprise one or more of stainless steel, titanium, biocompatible polymer, and/or any other material that permits body 14 to function as described in this disclosure. In some embodiments, body 14 comprises a structural material that defines a plurality of the volume of body 14, and a coating material disposed around the structural material that defines at least a portion of the outermost surface of body 14. For example, the structural material can comprise one or more pores, passages, or interstices (e.g., can be porous) and be substantially-rigid and/or biocompatible (e.g., metal foam, polymer lattice, and/or the like), and/or the coating material can comprise a substantially smooth and hard biocompatible coating (e.g., ceramic, polymer, metallic shell, and/or the like). In such composite embodiments, coupling side can be configured to permit bone ingrowth by configuring the coating material to cover substantially all of concave side 22 but does not cover substantially all of coupling side 18 (e.g., coating material does not cover all or part of coupling side, such that bone ingrowth is permitted into the pores, passages, or interstices of the structural material.
In the embodiment shown, body 14 further includes an outer side 50 that cooperates with concave side 22 to form an outer rim 54 (e.g., a round or radius between outer side 50 and concave side 22). In this embodiment, coupling side 18 and concave side 22 also cooperate to form an inner rim 58 (e.g., a round or radius between coupling side 18 and concave side 22). In the embodiment shown, inner rim 58 is concave, and outer rim 54 is convex. In this embodiment, outer rim 54 is configured to augment the articular rim of the glenoid of a patient.

In the embodiment shown, pin 200 has a first end 204, a second end 208, and a depth indicator 212. In this embodiment, pin 200 is configured to be inserted into the bone adjacent the selected type of human joint socket through one of the one or more holes 116a, 116b in body 104 of the jig to a depth indicated by depth indicator 212 such that second end 208 extends a predetermined distance out of the bone. For example, in the embodiment shown, depth indicator 212 comprises a line or other mark printed, engraved, etched, or otherwise visible at a selected point on the pin and corresponding to a portion of second side 108 of body 104 of the jig. In this embodiment, when jig 100 is disposed with first side 108 in contact with the articular surface of a patient's glenoid, pin 200 can be inserted into one of holes 116a, 116b until depth indicator 212 is aligned with the distal end 132a, 132b of the corresponding one of projections 124a, 124b. In the embodiment shown, first end 204 of pin 200 comprises a self-tapping tip 216 and threaded portion 220 such that pin 200 can be inserted to a desired depth relative to a bone and threaded portion 220 will substantially maintain the position of pin 200 relative to the bone.

Certain embodiments of the present methods will now be described with reference to
Some embodiments of the present methods repairing a human joint socket (e.g., glenoid), comprise: coupling a device (e.g., 10) with a pre-formed body (e.g., 14) to a bone adjacent to a human joint socket, where the body comprises a coupling side (e.g. 18) and a concave side (e.g., 22) disposed at a non-parallel angle relative to the coupling side, and the body is coupled to the bone such that the coupling side faces the bone and the concave side augments the articular surface of the joint socket.
Some embodiments of the present methods further comprise: shaping, prior to coupling the body to the bone, the bone to correspond to the shape of the coupling side. For example, in some embodiments, shaping comprises: disposing a jig (e.g., 100) such that first side 108 contacts articular surface (e.g., 416) of the joint socket, as shown in
In embodiments using jig 100 or other jigs having two or more holes (e.g., 116a, 116b), the present methods can further comprise inserting a second pin 200 or inserting the same pin 200 a second time. For example, in some embodiments, two pins 200 are inserted through holes 116a, 116b before removal of jig 100 from the bone, and reamer 300 is disposed and rotated sequentially over each pin 200 while both pins are disposed in the bone, as shown in
Once the bone has been shaped, device 10 can be disposed adjacent to the bone with coupling side 18 facing mating surface 424, as shown in
The use of devices 10a, 10b and jig 100a proceeds in similar fashion to that described above for
Some embodiments of the present kits comprise: one or more devices 10, 10a, and/or 10b and one or more of the present apparatuses (e.g., each including a jig 100 or 100a, at least one pin 200, and at least one reamer 300). For example, some embodiments of the present kits comprise a device (10, 10a, and/or 10b), a jig (100 and/or 100a), two or more pins 200, and a reamer 300. In some embodiments, the device(s) and apparatus(es) are sterile and/or disposed in a sealed package (e.g., a polymer tray with a sealing file).
The above specification and examples provide a complete description of the structure and use of exemplary embodiments. Although certain embodiments have been described above with a certain degree of particularity, or with reference to one or more individual embodiments, those skilled in the art could make numerous alterations to the disclosed embodiments without departing from the scope of this invention. As such, the various illustrative embodiments of the present devices, apparatuses, kits, and methods are not intended to be limited to the particular forms disclosed. Rather, they include all modifications and alternatives falling within the scope of the claims, and embodiments other than the one shown may include some or all of the features of the depicted embodiment. For example, jig 100 and reamer 300 can be configured such only one hole is included in the body of the jig to receive and position a pin 200 (e.g., in the embodiment shown, the diameter of reamer 300 is such that two pins and two applications of reamer to the bone in two different positions will generally be required for form the mating surface on the bone; but, in other embodiments, jig 100 can comprise a single, central hole for positioning the pin, and the cutting end of the reamer can have a diameter that is large enough to form the mating surface with a single application of the reamer. For example, components may be combined as a unitary structure, and/or connections may be substituted. Further, where appropriate, aspects of any of the examples described above may be combined with aspects of any of the other examples described to form further examples having comparable or different properties and addressing the same or different problems. Similarly, it will be understood that the benefits and advantages described above may relate to one embodiment or may relate to several embodiments.
The claims are not intended to include, and should not be interpreted to include, means-plus- or step-plus-function limitations, unless such a limitation is explicitly recited in a given claim using the phrase(s) “means for” or “step for,” respectively.
