Background Art

[0002] Shoulder arthroplasty is a common method for treating a shoulder joint that has become dysfunctional due to disease or trauma and is. In a healthy shoulder joint, the humeral head is generally ball-shaped and articulates within a socket formed by the scapula, called the glenoid fossa. Conventional implant systems for completely replacing the shoulder joint (e.g., total shoulder arthroplasty (TSA)) generally reproduce the natural anatomy of the shoulder and include a metallic humeral component that has a stem that fits within the humeral canal and a head that articulates within a socket of a plastic glenoid fossa component that is embedded within the glenoid fossa of the scapula. The glenoid fossa component may be a single-piece component attached to the glenoid fossa or a two-piece component having a plastic glenoid fossa component attached to a metallic baseplate and then attached to the glenoid fossa. In some cases, only a portion of the shoulder joint may be replaced, for example, by replacing the humeral head with an artificial humeral head configured to articulate within the natural glenoid fossa of the scapula (e.g., hemiarthroplasty of the shoulder (HAS)).

In some embodiments, the metal tapered extension 525 is the metal tapered extension 52 It includes one or more vertical slots or grooves 528 extending from the distal end of 5. In this embodiment, such vertical slots or grooves 528 allow the metal to taper The extension 525 deforms slightly so as to advance sufficiently into the recess 516 of the anchor boss 514. This allows for sufficient tapering between the metal-to-metal contact between the metal tapered extension 525 and the inner surface of the recess 516. Alternatively, friction locking can be provided. In some embodiments, such vertical The slot or groove 528 is more rigid to the inner surface of the recess 516 in the metal tapered extension 525. Provides an edge that offers a rigid taper or friction fit.

In Figure 30, the central compression screw 118b b has a length of approximately 40 mm, but has the same shaft diameter and tooth diameter as Figure 29. Figures 27-29 One embodiment shown in 30 is a central compression screw 118aa, 118ab having a tooth diameter of 6.5 mm. Does the head match the head of a central compression screw 118ba or 118bb with a tooth diameter of 8 mm? This means that it can be enlarged from its original dimensions to have approximately the same dimensions as this. In such an embodiment, the same base plate is used for a 6.5 mm or larger head having the same head dimensions. It can be used in applications that utilize an 8mm central compression screw 118.

In Figure 33, the central compression screw 118c has a tooth diameter of approximately 8.5 mm, and the base plate 21 The opening 2116c of 10c is, accordingly, larger than, for example, the openings 2116a and 2116b. It is made to the appropriate size. In Figure 34, the central compression screw 118d has a tooth diameter of approximately 9 mm. And the opening 2116d of the base plate 2110d is, accordingly, for example, opening 2116 The appropriate size is made larger than a~2116c. Some such embodiments are patient To address increased bone loss and / or poor bone quality in patients, larger diameters are used. We provide a central compression screw.

[0125] Figures 41A and 41B show yet another modular system 41 for shoulder joint replacement surgery. The diagram shows several figures of the modular system 4100, including the articular fossa component 41 20, and a base plate wedge 4110 with a full wedge, and a modular boss It comprises a central anchor screw 4118, and the central anchor screw 4118 itself is, in several embodiments Instead of the base plate 4100 having the aforementioned central boss, the proximal boss 41 Includes 14.

[0126] The base plate wedge 4110 is perpendicular to the axial direction of the extension of the central compression screw 118. It includes a substantially planar top surface that is (i.e., vertical). The top surface is one of the surfaces shown in Figures 35A to 35G.

In some embodiments, the given angle is approximately 7°. However, this disclosure is not limited to this, and any other appropriate angles may be considered.

[0127] In contrast to some other embodiments, the base plate includes a central boss portion extending from the bottom surface. Instead of the edge 4110, the bossed central anchor screw 4118 itself is used on the base plate 4 Includes a proximal boss 4114 configured to connect within the opening 4116 on the lower surface of 110. For example, but not limited to, the inner surface of the opening 4116 includes a locking mechanism 4119a, and the proximal boss 4 114 is a complementary locking mechanism 4119b configured to engage with the locking mechanism 4119a. This may include a locking mechanism 4119a and 4119 b includes a bayonet lock mechanism. In some embodiments, the proximal boss 4114 is When the central anchor screw 4118 with boss is pushed into the patient's bone to the desired depth, the patient It includes a thread 4115 configured to engage with the bone. However, the proximal boss 411 4 is a porous layer configured to aid in bone fusion and internal growth, either in addition or instead. This includes the following: Therefore, the practitioner inserts the bossed central anchor screw 4118 into the patient's bone to the desired depth. It can be pushed in so that the screw thread 4115 (if present) bites into the patient's bone, The central anchor screw 4118 with a screw head is designed to be fixed to the bone. After that, the practitioner, The central anchor with a boss engages with the locking mechanisms 4119a and 4119b until they engage with each other. Insert the proximal end of part 4118 into the opening 4116 from the lower surface of the base plate wedge 4110. By doing so, the base plate wedge 4110 is connected to the central anchor screw 4118 with a boss. It can be snap-fitted to it. In this embodiment, the base plate 411 By snapping the 0 into the bossed central anchor screw 4118, the bossed central anchor The central compression screw 4118, like the central compression screw 118, attaches to the base plate 4110 after assembly. It can be compressed to a desired position.

[0128] As shown in Figures 41A and 41B, the articular fossa component 4120 is, for example, in Figure 2 The above-mentioned part in relation to 6 may be substantially the same. Therefore, the glenoid fossa component 4 120 has an arc-shaped upper surface 122, a recess 4121 on the lower surface, and a central tapered portion 4 extending from the lower surface. It may include 124, and the opening 4129 is located on the upper surface 122, and the articular fossa component It extends through T4120 and is configured to accept an implant lock screw (not shown). This type of implant lock screw is used with the base plate wedge 4110. For example, the upper inner wall of opening 4116 and / or the central anchor screw 4118 with boss It is configured to engage with at least one complementary thread on the inner surface of the proximal boss 4114. It may include distal threads.

[0129] The glenoid fossa component 4120 and the base plate wedge 4110 are each made of gold. The genus, or other suitable biocompatible materials, e.g., titanium (Ti) and / or cobalt Alloys (e.g., cobalt-chromium (CoCr), cobalt-chromium-molybdenum (CoC)) It can include rMo).

[0130] Throughout this disclosure, central threads are often used in a compression role (for example, (Central compression screw 118). That is, the central compression screw 118 is properly positioned within the patient's bone. After tightening, the baseplate or Ancabos is pressed against the patient's bone and / or the patient It compresses to a fixed position within the bone of the person. The central compression screw 118 is another component (for example, base Disclosed herein, a plate or ankavos used to fix a patient's bone. In any of the embodiments described, the central compression screw 118 (for example, 118a in Figure 42 and Figure 42) is used. Between 43 (118b) and the opening where the central compression screw 118 is located, there are several interconnected It can have related characteristics.

[0131] For example, but not limited to, Figure 42 shows an exemplary base plate 4210 and central compression A cross-sectional view of screw 118a is shown. The base plate 4210 has a central boss portion 4 extending from the top surface. 214, opening 42 located through the central boss portion 4214 and the base plate 4210 16, and a perimeter opening 4215 for receiving the aforementioned perimeter screw 312. In one embodiment, for example, as described in any part of this disclosure, base play The 4210 is configured such that the central boss portion 4214 engages with the Grenosphere component. It can be used in reverse joint replacement surgery.

[0132] The opening 4216 is configured to receive the central compression screw 118a through it, central The head of the compression screw 118a is positioned to seat on the smaller diameter of the distal end of the opening 4216. Thread 4216 is a set of one or more threads, for example, complementary threads of a set screw 4217. Alternatively, an upper set configured to engage with the aforementioned implant locking screw, and In such cases, the central compression screw 118b is configured to engage with the complementary thread 119 on the head. It can include a lower set (see, for example, Figure 43).

[0133] In the embodiment shown in Figure 42, the head of the central compression screw 118a has at least an opening 4 Includes threads configured to engage with the lower set of complementary threads within the small-diameter distal portion of 216. In that it does not have a smooth outer surface, it has a nearly smooth outer surface. Therefore, in Figure 42, the central compression screw 11 8a does not screw into the base plate 4210. Set screw 4217 also opens 42 Includes threads configured to screw-engage with the upper set of 16 proximal complementary threads. When the set screw 4217 is properly seated within the opening 4216 as shown in the figure, it will be centrally located within the body. The compression screw 118a may be configured to prevent it from retracting. In some embodiments The threads of the set screw 4217 resist the torque applied to the assembly within the body and / or In contrast, the central compression screw 118a has a "left-right" direction opposite to the thread direction. Yes (for example, if the thread of screw 118a is right-handed, then left-handed; if the thread of screw 118a is left-handed) (If so, see the right). This disclosure relates to any of the implant locking screws described herein. While it's possible to use the opposite left and right for the mountain shape, it's not necessary.

[0134] As a contrasting but not limited example, Figure 43 shows the base plate 4210, retaining pin. 4217 and complementary threads 4 in the lower threads within the small diameter distal portion of the opening 4216 of the head A cross-sectional view of the central compression screw 118b having 319 is shown. Therefore, the central compression screw 118 When b is properly seated within the opening 4216, it engages with the base plate 4210 via screws.

[0135] The use of a set screw to lock the central screw is in the embodiments shown in Figures 42 and 43. Not limited to this. For example, Figure 44 shows the modular system 4400 used in shoulder joint replacement surgery. An embodiment is shown. System 4400 includes an articular component 4420 and a set screw 4 Instead of 417, it is fixed to the bone by a central compression screw 118 that locks itself. It is equipped with a -plate 4410.

[0136] The articular fossa component 4420 has an arc-shaped upper surface 122 and, optionally, a recess 4 on the lower surface. The aforementioned articular components, including 421 and 2120 in Figure 21, and / or Or it may be substantially the same as 4120 in Figure 41. Although not visible in Figure 44, the articular fossa component Nent 4420 extends from the lower surface of the articular fossa component 4420 within the recess 4421. It includes a central tapered section (see, for example, 4124 in Figure 41). Also, it is not shown in Figure 44. However, the arc-shaped upper surface 122 has an opening (e.g.,) configured to receive an implant lock screw. For example, it may include (see Figure 41, 4129), and the implant lock screw is explained below. As clarified, the head of the set screw 4417, the central compression screw 118, and / or base The rate 4410 is configured to engage with the complementary threads on the side walls of the central opening 4416 on the upper surface. It has distal threads, thereby connecting the glenoid component 4420 to the base plate 44 Secure it with screws at 10.

[0137] The base plate 4410 accepts the central compression screw 118, followed by the set screw 441 It includes a central opening 4416 configured to accept 7. Thus, the opening 4416, The central compression screw 118 and the set screw 4417 are located at the central boss portion 4414 in Figures 42 and 42. Except for the fact that it extends from the bottom surface rather than the top surface of the base plate 4410, as in 43, This corresponds substantially to what was described in relation to Figures 42 and / or 43, and has similar characteristics. It is possible to have.

[0138] In some such embodiments, the inside of the set screw 4417 is the articular fossa component A central tape extending from the lower surface of the articular fossa component 4420 within the recess 4421 of T 4420 It may include a tapered recess configured to receive a portion. Some other embodiments In this configuration, the set screw 4417 is located in the recess 4421 on the lower surface of the articular fossa component 4420. The central tapered section extending from it fits perfectly within the opening 4416 on the upper surface of the base plate 4410 itself. It is seated and configured to tapere and / or friction fit into the opening 4416. Therefore, it can have a sufficiently low external form (for example, it has a sufficiently low height).

[0139] The articular component 4420, base plate 4410, and set screw 4417 are Each of these is a metal or other suitable biocompatible material, such as titanium (Ti) and / or or cobalt alloys (for example, cobalt-chromium (CoCr), cobalt-chromium-molybdenum) It can contain den(CoCrMo).

[0140] Figure 45 shows yet another exemplary real-world example of the modular system 4500 for shoulder joint replacement surgery. The configuration is shown. System 4500 is the aforementioned Grenosphere component 1220 and The base plate in Figure 44 is configured to be fixed to the patient's bone by a central compression screw 118. It features a rate 4410 and a threaded Glenosphere adapter 4530.

[0141] The base plate 4410 receives the central compression screw 118 through the central opening 4416. It is configured in such a way that when the central compression screw 118 is properly set and tightened, it stops Instead of using screw 4417, use at least the threaded portion of the Grenosphere adapter 4530. 4534 is located on the proximal part of the threads of the opening 4416, similarly to the set screw 4417 in Figure 44. It is screwed into the set. The tapered part 4532 of the Grenosphere adapter 4530 is screwed. It is positioned adjacent to part 4534, and the threaded part 4534 is properly screwed into the opening 4416. Furthermore, it is configured to extend from the upper surface of the base plate 4410. Tapered portion 453 2 is the recess 1224 of the Grenosphere component 1220 (not shown, but for example, Figure 1 (See reference 2) Once properly seated within, the implant lock screw 4527 is inserted into the Grenosphere The component 1220 is positioned through the central opening of the adapter 4530 within the opening 1229. It is possible. The distal thread of the implant lock screw 4527 is attached to the adapter 4539. The central opening, the opening 4416 of the base plate 4410, or the aforementioned central compression screw 11 It is configured to engage with at least one complementary thread on one of the 8 heads.

[0142] Therefore, the Glenosphere adapter 4530 as an integrated component is central pressure Set screws for the retractable screw 118 and the Grenosphere component 1220 on the base plate It is configured to act as both an adapter for connecting to the 4410. The threading required for it to function as a joint is to connect adapter 4530 to base plate 4410. It also serves a fixing function. Adapter 4530 also stacks each with tolerances for depth precision. Improve depth accuracy with fewer components. The above is one function. However, all examples of adapter 4530 are used simultaneously for other previously unrelated functions. .

[0143] Figure 46 shows yet another exemplary real-world example of the modular system 4600 for shoulder joint replacement surgery. The configuration is shown. In some embodiments, the system 4600 is placed on the approximate surface of the subchondral bone. It may be configured to do so. System 4600 does not include a base plate. Instead The system 4600 is configured to have a bossed head 4614 and to bite into the patient's bone. It features a central anchor screw 4618 with a boss having a threaded head. In some embodiments, At least a portion of the bossed head 4614 of the bossed central anchor screw 4618 is recessed Later, it was coated with a porous metal coating designed to help the bones fuse together. Alternatively, it is formed to have a porous metal coating by other means. Some embodiments In this context, the head 4614 with a boss is, as will be described in more detail below, an articular fossa component A mating fitting configured to engage with the metal disc-shaped component 4624 of the Nent 4620. or include a locking mechanism (not shown, but for example, teeth, projections, and / or protrusions).

[0144] In some embodiments, the articular component 4620 is a metal disc-shaped component Instead of using T924, a metal disc-shaped component 4624 is used for the articular fossa component. Formed, integrally formed, cast, rolled, or from the same metal piece or metal alloy as 4620. Except for being inserted into the bottom surface of the glenoid fossa component 4620, the glenoid fossa shown in Figures 9-11 It is a multi-part assembly that is very similar to component 920 (for example, similar ridged protrusions 4 (Including 626). Metal disc-shaped component 4624 is articular component 4620 Provides a key interface between the central anchor screw 4618 with a boss.
