Description

[Technical field]

[0001] (CROSS REFERENCE TO RELATED APPLICATIONS) This application claims the benefit of and priority to U.S. Provisional Patent Application No. 63 / 209,845, filed June 11, 2021, the entire contents of which are incorporated herein by reference.

[0002] FIELD OF THEINVENTION The present invention relates generally to orthopedics, and more particularly to prostheses for use in orthopedics. [Background technology]

[0003] The human shoulder is a ball-and-socket joint with the greatest range of motion in the body. The ball, including the top end or head of the humerus, is fixed against the glenoid, a shallow socket in the scapula, and is held in place by muscles and other soft tissues. In a healthy joint, the rotator cuff muscles, including the supraspinatus, help balance the head of the humerus in the glenoid socket against the upward pull of the deltoid. When the joint is healthy, the head of the humerus moves smoothly within the glenoid socket. However, arthritis, bone disease, or injury can fundamentally affect the smooth functioning of the shoulder joint, and the joint may need to be repaired or reconstructed with a procedure in which an artificial humeral stem is inserted into the humerus to interface with the natural glenoid socket, or with a prosthesis attached to the glenoid socket.

[0004] In some conditions, such as rotator cuff arthropathy, failure of traditional hemiarthroplasty or acromioplasty with superior prolapse of the humerus, and other conditions, it may not be possible to repair or reconstruct the normal relationship between the "ball" and "socket" of the joint. In these circumstances, the only option may be to repair or reconstruct the joint using a "reverse" prosthesis, which uses a socket where the ball (head of the humerus) would normally be, and a ball where the socket (glenoid) would normally be. Such repair or reconstruction can restore some function to the damaged joint by providing stability and an effective fulcrum for the deltoid to lift the humerus up to a level where it can perform basic shoulder functions.

[0005] In some circumstances, damage to the proximal (or upper) portion of the humerus can make it difficult to place a humeral stem deep enough to provide the stability and necessary physical orientation required for proper mechanical function of the prosthesis. In such cases, to augment the necessary bone structure, surgeons often require the addition of bone grafts from cadaveric bones, which must be cut and shaped during surgery. However, bone grafts are expensive and difficult to shape properly. Furthermore, many surgeons are unsure about acquiring the skills necessary to properly shape the bone grafts during surgery. When bone grafts are required through traditional surgical procedures, it is often difficult to revise or reverse the joint repair if aftermath reveals that the original repair failed.

[0006] It would be desirable to have a prosthetic component that provides a more normal function to a shoulder joint following injury to the proximal humerus. It would also be desirable to have such a prosthetic component that would eliminate the need for additional bone graft material in cases where there is significant bone loss in the proximal end of the humerus. It would also be desirable to have a prosthetic component that provides increased stability and allows for repair of the joint.

[0007] Further objects and advantages of the present invention will become apparent from a consideration of the drawings and ensuing description. [Brief description of the drawings]

[0017] FIG. 1 illustrates an anterior view of the bones of a healthy human shoulder joint. As shown herein, the humerus 100 includes a head 102 that forms the "ball" portion of the ball-and-socket joint. The generally spherical humerus head 102 contacts a glenoid cavity 104 of the scapula 106 that forms the "socket" portion of the glenoid joint (or shoulder joint). The glenoid cavity is a cartilaginous cavity against which the humerus head slides and rotates. Adjacent to the glenoid cavity is the coracoid process 108. Other bones of the shoulder include the acromion 110 and the clavicle 112. The humerus 100 is held in place relative to the scapula 106 by passive suspension with the assistance of various ligaments (not shown) and active suspension in which the rotator cuff muscles, including the supraspinatus, effectively balance the humerus head within the glenoid socket against the upward pull of the deltoid muscle.

[0018] Arthritis, bone disease, or injury can fundamentally affect the smooth functioning of the shoulder joint. In a primary joint repair procedure, the head of the humerus is usually resected and a prosthetic stem is implanted into the humerus. A prosthetic ball is attached to this stem, and a prosthetic socket is implanted into the glenoid cavity to articulate with the prosthetic ball. However, in some conditions, repair or reconstruction that preserves the normal spatial relationship between the "ball" and "socket" of the joint may not be possible. In these situations, the only option may be to repair or reconstruct the joint using a "reverse" prosthesis, which uses a socket where the head of the humerus would normally be, and a ball where the glenoid cavity would normally be.

[0019] In some cases, bone disease or damage to the proximal (or upper) portion of the humerus to such an extent that it is difficult to place a humeral stem deep enough to provide the stability and necessary physical orientation required for proper mechanical function of the prosthesis. In such cases, traditional procedures often require the surgeon to add bone graft from cadaveric bone, which must be cut and shaped during surgery, to increase the necessary bone structure to support the prosthetic components.

[0020] 2-37 illustrate a humeral component for use in a "reverse" shoulder joint repair or reconstruction according to the present invention to support a portion of the shoulder muscles in a manner that allows normal joint function to be maintained. Such a component is adapted to cooperate with a ball portion of a glenoid component adapted for attachment to the scapula of the shoulder joint. These components can also be used when there is significant damage to the proximal end of the humerus without adding a bone graft to the humerus. Although FIGS. 2-37 depict a humeral component for use in a "reverse" shoulder joint repair, the embodiment is not so limited. In one embodiment, the humeral component can include a stem and a glenosphere. For example, the cup portion 208 of the humeral stem component 200 depicted in FIG. 2 can be replaced with a glenosphere.

[0021] A first embodiment of an orthopedic component is shown in Figures 2 and 3. In the example depicted in Figure 2, the orthopedic component is a humeral component 200. The humeral component 200 includes a stem portion 202 having a proximal end 204 and a distal end 206. In one embodiment, the stem portion 202 is constructed from a biocompatible metal, such as titanium. An anatomical feature is attached to the proximal end 204 of the stem portion 202. The anatomical feature is configured to mate with a corresponding structure (e.g., another prosthesis, bone, etc.). In the example depicted in Figures 2 and 3, the anatomical feature is a cup portion 208. In this example, the cup portion 208 is configured to mate with a prosthetic socket implanted in a patient's glenoid cavity. However, it should be noted that the embodiments are not so limited and any suitable type of anatomical feature can be used. For example, the anatomical feature is a glenosphere. When the anatomical feature is a glenosphere, the glenosphere may be configured to mate with the patient's bone or a prosthesis secured to the patient's bone. In the embodiment depicted in FIGS. 2-3, the cup portion 208 includes a socket 210 adapted to receive a ball portion of a glenoid component (not shown in FIGS. 2 and 3). Preferably, the cup portion 208 is constructed from a biocompatible metal. The socket 210 may be made of any suitable material (e.g., ceramic or an ultra-high molecular weight polyethylene (UHMWPE) cup liner). Attached to and positioned outwardly of the cup portion 208 is a plate 212, preferably of a biocompatible metal, which is spaced from the cup portion 208 and has a contoured outer surface 214 for placement of patient tissue (not shown in FIGS. 2 and 3) thereon. In the example of a humeral component, the plate 212 may interact with the patient's deltoid muscle. The plate 212 may be of any suitable length. Thus, the plate 212 may extend to a desired portion of the stem portion 202. For example, the plate 212 can be about 10% of the length of the stem portion 202, about 20% of the length of the stem portion 202, about 30% of the length of the stem portion 202, about 50% of the length of the stem portion 202, about 75% of the length of the stem portion 202, about 100% of the length of the stem portion 202, etc.Additionally, in some embodiments, the length of the plate 212 may exceed the length of the stem portion 202 .

[0022] In the embodiment of the orthopedic component illustrated in FIGS. 2 and 3, the proximal portion 216 of the plate 212 is curved laterally to concave toward the cup portion. In this embodiment, the plate 212 is also curved longitudinally at its distal end 218 to describe an S-shaped curve. In addition, the plate 212 includes a downward flange 220 and a pair of wings 222. In some embodiments, one or more of the pair of wings 222 includes at least one attachment hole 224. Such attachment hole 224 can be used to suture muscle or other tissue to the humeral component 200. In some embodiments, the flange 220 also includes a pair of wings 226. In some embodiments, one or more of the pair of wings 226 includes at least one attachment hole 228. The at least one attachment hole 228 can be configured to receive a screw or other fastener (not shown), for example, to attach the plate 212 to a portion of the humerus (not shown in FIGS. 2 and 3). In some embodiments, by providing a humeral component that includes a plate 212 that is attached to the cup portion 208 and configured and positioned to allow placement of the deltoid muscle thereon, the physical orientation necessary for proper mechanical function of the joint is maintained. In some embodiments, by providing a plate 212 that includes wings 226 for attachment to a portion of the humerus that has been somewhat removed from the joint, stability can be provided to the prosthesis without the need for additional bone graft material.

[0023] A second embodiment of an orthopedic component is shown in Figures 4-7. In the example depicted in Figures 4-7, the orthopedic component is a humeral component 230. The humeral component 230 includes a stem portion 260 (partially shown in Figure 7) adapted to be inserted into a bone, such as the humerus 262, and a cup portion 232. In one embodiment, the cup portion 232 is attached by a tapered trunnion 234 to a corresponding tapered socket 264 within the proximal end of the stem portion 260. Preferably, the stem portion 260 and the cup portion 232 of the humeral component 230 are constructed from a biocompatible metal. The humeral component 230 is adapted to cooperate with a glenoid component 266 (shown in Figure 7). In one embodiment, the glenoid component 266 is adapted to be attached to a scapula 268 using a number of fasteners 270. The glenoid component 266 includes a ball portion 272 adapted to articulate within the socket 236 of the cup portion 232. In some embodiments, the socket 236 includes a liner, such as a ceramic or polyethylene (e.g., an ultra-high molecular weight polyethylene (UHMWPE) liner). The plate 238 is attached to the cup portion 232 of the humeral component 230 by a generally planar connecting wall 240. In some embodiments, the connecting wall 240 is positioned such that the diameter of the cup portion 232 is within the plane of the connecting wall 240. In some embodiments, the connecting wall is constructed from the same material as the cup portion 232. In one form, the plate 238 is positioned outwardly of the cup portion 232 and is spaced apart from the cup portion 232 and has a contoured outer surface 242 for placement thereon of a deltoid muscle (not shown in FIGS. 4-7 ).

[0024] As best shown in FIG. 4 , the proximal portion 244 of the plate 238 is laterally curved to concave toward the cup portion 232. In some embodiments, the plate 238 is also longitudinally curved at its distal end 246 to form an S-curve and terminate in a downward flange 248. In some embodiments, the plate 238 and the connecting wall 240 each include a plurality of attachment holes 250 and 252. The plurality of attachment holes 250 and 252 can be used, for example, to suture muscle or other tissue to the humeral component 230. Additionally, the cup portion 232 can include a plurality of suture sites 252, each including at least one suture hole 256. Such suture sites 252 can be used to suture muscle or other tissue to the humeral component 230. Additionally, the flange 248 of the plate 238 can include an attachment hole 258. The attachment holes 258 can be configured to receive, for example, a wire or suture (not shown in FIGS. 4-7) that is wrapped around the humerus to secure the plate 238. Thus, in such embodiments, the flange 248 can include any suitable number of attachment holes 258. In some embodiments, a prosthetic assembly including a tissue support such as a plate 238 attached to the cup portion 232 and configured and arranged for tissue (e.g., muscle) to be placed thereon provides the physical orientation necessary to maintain proper mechanical function of the joint. In some embodiments, a plate 238 including a flange 248 having attachment holes 258 for attachment to a portion of bone somewhat removed from the joint can provide stability to the prosthesis without the need for additional bone graft material.

[0025] A third embodiment of an orthopedic component is shown in Figures 8 and 9. In the example depicted in Figures 8 and 9, the orthopedic component is a humeral component 274. The humeral component 274 includes a stem portion 276 adapted to be inserted into a humerus 300 (shown in Figure 9). In some embodiments, the humeral component includes a cup portion 278. The cup portion 278 may be secured to the stem portion 276 in any suitable manner. For example, the cup portion 278 may be secured to the stem portion 276 via a tapered trunnion 280 to a corresponding tapered socket (not shown) at the proximal end of the stem portion 276. In some embodiments, the stem portion 276 and the cup portion 278 are constructed from a biocompatible metal, such as titanium, stainless steel, cobalt chrome, or the like. In one form, the humeral component 274 is adapted to cooperate with a glenoid component adapted to be attached to the scapula 302 using a number of fasteners (not shown). In one embodiment, as shown in FIG. 9, the glenoid component includes a ball portion 304 adapted to articulate with a socket in the cup portion 278. The socket may be provided in the form of a cup liner. The cup liner may be made of any suitable material, such as ceramic, plastic (e.g., polyethylene), etc. A plate 282 is attached to and positioned outwardly of the cup portion 278 with its outer surface 284 spaced from the cup portion 278 and contoured to accommodate placement of the deltoid muscle 314 (shown in FIG. 9) thereon. In one embodiment, the plate 282 is constructed from the same material as the cup portion.

[0026] In some embodiments, the proximal portion 286 of the plate 282 is curved laterally to concave toward the cup portion 278. Additionally, in some embodiments, the plate 282 is also curved longitudinally at its distal end 288 to describe an S-curve and terminate in a downward flange 290. In one form, the cup portion 278 includes a plurality of suture sites 292, each of which includes at least one suture hole (such as hole 294 shown in FIG. 8) for use in suturing a muscle (such as the subscapularis 310 shown in FIG. 9) or other tissue to the humeral component 274. In some embodiments, the flange 290 of the plate 282 also includes a plurality of attachment holes 296. The plurality of attachment holes 296 may be any suitable number and in some embodiments are configured to receive a wire 312 or suture that may be wrapped around the humerus to secure the plate 282 thereto. In some embodiments, a prosthetic assembly including a tissue support, such as a plate 282 attached to the cup portion 278 and configured and arranged for tissue (e.g., muscle) to be placed thereon, provides the physical orientation necessary to maintain proper mechanical function of the joint. In some embodiments, the plate 282 including a flange 290 having an attachment hole 296 for attachment to a portion of bone somewhat removed from the joint can provide stability to the prosthetic joint without the need for additional bone graft material.

[0027] A fourth embodiment of an orthopedic component is shown in Figures 10-12. In the example depicted in Figures 10-12, the orthopedic component is a humeral component 316. In some embodiments, the humeral component 316 is a unitary structure including a stem portion 318, a cup portion 320, and a plate 322. In one form, the humeral component 316 is constructed from a biocompatible metal. In some embodiments, as depicted in Figure 10, the plate 322 is disposed opposite the cup portion 320. The stem portion 318 includes a proximal end 324 and a distal end 326 adapted to be inserted into a humerus 334 (shown in Figure 12). The cup portion 320 includes a socket 328 (shown in Figure 11) adapted to receive a ball portion (not shown, but which may be substantially similar to the ball portion 304 of Figure 9) of a cooperating glenoid component. The socket 328 may include a liner. The liner can be made of any suitable material (e.g., ceramic, plastic, etc.). Plate 322 protrudes from cup portion 320. In some embodiments, plate 322 includes a contoured outer surface 336. In such embodiments, the contour allows for placement of tissue (e.g., muscle) thereon. In some embodiments, the proximal portion of plate 322 includes a flange 330 that extends downwardly alongside a portion of stem portion 318 (as exemplified in FIG. 10 ), and in such embodiments, flange 330 preferably includes a number of attachment holes 332. The number of attachment holes can be any suitable number and can be configured to receive a wire 338 or suture that can be wrapped around the bone to secure plate 322 thereto. In some embodiments, a one-piece humeral component including a tissue support such as plate 322 integrally formed with cup portion 320 and configured and arranged to allow placement of tissue thereon provides the necessary physical orientation to maintain proper mechanical function of the joint. In some embodiments, a plate 332 including a flange 330 with mounting holes 332 for mounting to a location of bone somewhat removed from the joint can provide stability to the artificial joint without the need for additional bone graft material.

[0028] A fifth embodiment of the orthopedic component is shown in Figures 13-15. Figures 13-15 depict a shoulder joint including a scapula 106, including a coracoid 108 and an acromion 110, and a portion of a humerus 100 exhibiting a severe proximal humerus deficiency. As depicted in Figures 13-15, the orthopedic component is a humeral component. In one embodiment, the humeral component includes a proximal humerus component 342, a ball component 340 and a cup component 344 interfacing with a distal plate, and a stem component 346 having a plurality of fasteners 348. In one form, the proximal humerus component 342, the distal plate, and the stem component 346 are constructed from a biocompatible metal. In one embodiment, the proximal humerus component 342 is adapted to cooperate with a glenoid component (not shown) adapted to be attached to the scapula 106 using a plurality of fasteners (not shown). 13, the glenoid component includes a ball portion 340 adapted to articulate with a socket in a cup portion 344. The socket may be provided in the form of a cup liner.

[0029] FIG. 14 shows a detailed view of a fifth embodiment of an orthopedic component. The proximal humerus component 342 has a cup component 344 that interfaces with a ball component (not shown). In one form, the features 350 and 352 use various attachment methods including sutures, fasteners, and the like to attach various structures including bone fragments, tendons, ligaments, and the like. The distal portion 354 of the proximal humerus component 342 is configured to provide rotational stability when connected to the distal plate and stem component 346. The distal plate and stem component 346 is comprised of a medial plate portion 362 and a stem portion 364. In one embodiment, one or both of the plate portions 362 include holes 358 and the stem portion includes holes 356. The holes 362 and / or holes 358 can be threaded or smoothed to receive a number of fasteners 348 that can be locked or unlocked, respectively.
