[0026] refer to Figure 1A, an embodiment of a prosthesis 100 for attachment to a glenoid cavity is provided. The prosthesis 100 includes a base body 110 that is a unitary metal structure. The base body 110 includes a distal surface 111, a proximal surface 112, and a post 120 that extends from the proximal surface 112. Features of the base body 110 and the post 120 are described herein that together provide orientation stability for a modular bone graft used with the prosthesis 100.

[0027] In some embodiments, the unitary metal structure of baseplate body 110 may be manufactured by an additive manufacturing process such as 3-D printing.Post 120 is configured to be disposed in a complementary hole or recess prepared in the glenoid to assist in attaching prosthesis 100 to the glenoid.

[0028] In some embodiments, the proximal surface 112 is configured to engage a modular bone augment, such as Figure 2 The bone augment 50 shown in the figure is fixed between the base body 110 and the glenoid of the patient. As shown in the example modular bone augment 50, the modular bone augment may have two main surfaces, namely a first surface 54 and a second surface 55. The first surface 54 engages the proximal surface 112 of the base body, and the second surface 55 faces the glenoid surface. The shape and contour of the second surface 55 are configured to fill the void in the degenerated glenoid. In some applications, the second surface 55 can be patient-matched to more accurately and effectively fill the void in the glenoid. Due to the function of the bone augment 50, the second surface 55 is generally angled and / or asymmetric and requires a specific orientation on the base. The bone augment 50 will need to be installed with the prosthesis 100 in a specific orientation to properly enhance the bone where there may be voids in the bone.

[0029] In some embodiments, such as Figure 1B As illustrated in the illustrated prosthesis 100A, the proximal surface 112 may be provided with a plurality of dimples 115 to promote ingrowth of bone tissue at the interface between the proximal surface 112 and the modular bone augmentation, thereby enhancing fixation of the prosthesis 100A after implantation.

[0030] The substrate body 110 may also include a plurality of fins 130 extending radially from the posts 120 at or near where the posts 120 meet the proximal surface 112. Figure 1AAs shown in the illustrated example in FIG. 1 , in some embodiments, a plurality of fins 130 can be positioned along a junction J where the post 120 meets the proximal surface 112 and extends radially along the proximal surface 112. As the fins 130 extend radially outward from the post 120, the fins can taper toward the proximal surface 112. In some embodiments, the modular bone augment 50 can be configured to receive the fins 130 when the bone augment 50 engages the proximal surface 112. For example, the first surface 54 of the bone augment 50 can be provided with a recess or groove positioned to receive the fins 130. The engagement between the fins 130 and the bone augment 50 can secure the bone augment 50 in a desired orientation relative to the base body 110 such that a desired specific orientation of the bone augment 50 can be maintained.

[0031] refer to Figure 2 , the modular bone augment 50 can be configured to slide over the post 120 and abut the proximal surface 112 of the base body 110. The bone augment 50 can be provided with a hole 52 extending from the first surface 54 through the thickness of the bone augment to the second surface 55. The size of the hole 52 is designed to receive the post 120 so that the bone augment 50 can slide over the post 120. The bone augment 50 is configured so that when the bone graft slides over the post 120, the first surface 54 abuts the proximal surface 112. The contour of the second surface 55 is designed to match the shape and contour of the void in the glenoid surface. The modular bone augment 50 can be made of a bone graft or a porous surgical grade material that is biocompatible in the human body when implanted. Such a porous material can be a metallic material, a ceramic material, or a polymer material. Figure 2 The example of the bone augment 50 shown has a generally cylindrical or disc-like shape, but the shape of the bone augment 50 need not be so limited. The shape and contour of the bone augment 50 can vary and can be provided in any shape necessary to enhance the void in the glenoid cavity, as long as the bone augment can be fixed to the proximal side of the base body 110 to maintain the desired specific orientation of the bone augment when the prosthesis 100, 100A is in place and to prevent the bone augment 50 from rotating about the post 120.

[0032] In embodiments where the modular bone augment 50 is made of bone graft, when the modular bone augment 50 is installed, its first surface 54 will contact the proximal surface 112 of the base body 110, and when the bone augment 50 is pressed against the proximal surface 112, the plurality of fins 130 can cut into the bone augment 50 and prevent the bone graft 50 from rotating about the post 120.

[0033] The plurality of fins 130 on the base plate may take on a variety of structural configurations, so long as they provide a means of preventing unwanted rotation of the modular bone augment 50 after the bone augment 50 is installed. Figure 1B and Figure 1CIn an embodiment of the prosthesis 100A, a plurality of fins 130A may be disposed on the post 120 and located near the junction J where the post 120 meets the proximal surface 112, but not in contact with the proximal surface 112. Figure 1B and Figure 1C In the particular example shown, the fins 130A disposed on the post 120 may be configured in a short tooth-like form and may be spaced apart from the joint J.

[0034] In some embodiments, the prosthesis 100, 100A may include a plurality of openings 140 disposed between the post 120 and the periphery of the base body for receiving one or more bone screws to help secure the prosthesis 100, 100A to the glenoid. Each of the plurality of openings 140 extends through the base body 110 from the distal surface 111 to the proximal surface 112.

[0035] In some embodiments, the post 120 can have a generally cylindrical shape with the diameter of the post gradually decreasing in the proximal direction.

[0036] refer to Figure 1D In some embodiments, the post 120 can be configured with a hole or channel 128 that can help align the joint component with the prosthesis 100, 100A when the joint component is attached to the base body 110. The channel 128 extends from the distal surface 111 into the post 120 along the longitudinal axis L of the post 120. In some embodiments, such as Figure 1D As shown in the example in FIG. 1 , the channel 128 can extend through the entire length of the column 120. The channel 128 terminates at the distal surface 111 and has a diameter suitable for tightly receiving the guide pin. In use, the guide pin can be inserted into the channel 128 from the distal surface 311 side so that the guide pin extends out of the channel 128 at the distal surface 111 side. A joint component (such as a base plate body 110) configured to cooperate with the base plate body 110 Figure 5D The example joint component 700 shown may be provided with corresponding holes or channels that are configured to receive guide pins extending out of the channels 128 so that the guide pins can help align the joint component 700 and the base plate body 110 when the two components are joined together.

[0037] Channel 128 may be a blind hole that extends into column 120 to a predetermined depth such that a guide pin fully inserted into portion A extends out of channel 128 an appropriate amount and provides a guide function for joint component 700 .

[0038] In some embodiments, the channel 128 may extend through the entire length of the post 120, such that the channel 128 is open at the distal surface 111 and at the proximal end of the post 120. In such an embodiment, the channel 128 may be constructed with two portions A and B, wherein portion A is the portion that is open at the distal surface 111 and receives the guide pin. Portion B may have a smaller diameter than portion A, such that the guide pin is too large to fit into the smaller diameter portion B. This configuration prevents the guide pin from exiting at the proximal end of the post 120 and entering the patient's bone. Additionally, having the channel 128 open at both ends allows for the discharge of debris and fluids generated during the manufacturing process of drilling the channel 128.

[0039] refer to FIG. 3A to FIG. 3B , a prosthesis 200 for attachment to a glenoid according to another embodiment is provided. The prosthesis 200 includes a base body 210 that is a unitary metal structure. The base body 210 includes a distal surface 211, a proximal surface 212, and a post 220 that extends from the proximal surface 212. Features of the base body 210 and the post 220 are described herein that provide orientation stability for a modular bone graft used with the prosthesis 200.

[0040] In this embodiment, the post 220 includes a tapered conical shape having a taper angle of about 5 to 30 degrees, whereby the diameter of the post decreases in a proximal direction from the base body 210. The tapered shape of the post 220 provides a gradual press-fit engagement with the glenoid, wherein the post 220 is pressed into the glenoid with some minimal preparation of the glenoid (i.e., reaming and / or drilling) or without any preparation of the glenoid.

[0041] The post 220 may also include a plurality of fins 230 disposed at a top end 220T of the post 220, wherein the fins 230 extend radially from the post 220. The top end 220T is the end of the post 220 that is farthest from the base body 210. The fins 230 may be shaped to further enable the tapered post 220 to be pressed into the glenoid with or without any preparation of the glenoid. For example, the leading edge of the fins 230 may be sharp like a blade and may be formed as Figure 3A The angle shown allows the fin 230 to cut into the glenoid and allows the tapered post 220 to be easily pushed into the glenoid.

[0042] In some embodiments, the unitary metal structure of baseplate body 210 can be manufactured by an additive manufacturing process such as 3-D printing.Post 220 is configured to be disposed in a complementary hole or recess prepared in the glenoid to assist in attaching prosthesis 200 to the glenoid.

[0043] In some embodiments, the prosthesis 200 may also include a plurality of second sets of fins similar to the plurality of fins 130 and 130A in the prosthesis embodiments 100 and 100A, respectively. Such second set of fins extend radially from the post 220 at or near the junction J where the post 220 meets the proximal surface 212. In some embodiments, the plurality of second sets of fins are located at the junction J and extend radially along the proximal surface, similar to Figure 1A Fins 130 are shown. In some embodiments, a second plurality of fins are located near junction J but do not contact proximal surface 212.

[0044] In some embodiments, the prosthesis 200 may further include a plurality of openings 240 disposed between the post 220 and the periphery of the base body for receiving one or more bone screws to secure the prosthesis 200 to the glenoid. Each of the plurality of openings 240 extends through the base body 210 from the distal surface 211 to the proximal surface 212.

[0045] In some embodiments, the prosthesis 200 can further include a modular bone augment 50 that is configured to slide over the post 220 and abut the proximal surface 212 of the baseplate body 210 .

[0046] refer to FIG. 4A to FIG. 4B , a prosthesis 300 for attachment to a glenoid cavity according to another embodiment is provided. The prosthesis 300 includes a base body 310, which is a unitary metal structure. The base body 310 includes a distal surface 311, a proximal surface 312, and a post 320, which extends from the proximal surface 312. In this embodiment, the post 320 includes a wireframe structure 325 having a cylindrical outer shape and defines an internal volume that is configured as a porous structure 327. Features of the base body 310 and the post 320 are described herein, which provide orientation stability for a modular bone augment used with the prosthesis 300.

[0047] In some embodiments, the unitary metal structure of the baseplate body 310 can be manufactured by an additive manufacturing process such as 3-D printing.The porous structure 327 can serve as a scaffold that promotes bone ingrowth after the prosthesis 300 is implanted in the glenoid.

[0048] Both the wireframe structure 325 and the porous structure 327 can be formed from the same metal material and can be formed simultaneously by an additive manufacturing process. This allows for a structurally composite (not materially composite, since the wireframe structure 325 and the porous structure 327 are made from the same material) configuration of the post 320, wherein the two structural portions (the wireframe structure 325 and the porous structure 327) are well integrated. The post 320 is configured to be disposed in a complementary hole or recess prepared in the glenoid to assist in attaching the prosthesis 300 to the glenoid.

[0049] In some embodiments of the prosthesis 300, the porous structure 327 can be configured to completely occupy the interior volume of the wireframe structure 325 to maximize the amount of bone ingrowth into the post 320. In some embodiments, similar to the post 120 in the prosthesis 100, 100A, the post 320 can be configured with a hole or channel 328 that helps align the glenosphere component with the prosthesis during attachment of the prosthesis 300 to the base body 310. The structure and function of the channel 328 are the same as the channel 128 provided in the post 120.

[0050] In some embodiments of the prosthesis 300, the proximal surface 312 can be configured with a surface layer 312a configured as a porous structure. This provides increased surface area on the prosthesis 300, which can promote bone ingrowth after the prosthesis 300 is implanted in the glenoid.

[0051] In some embodiments, the cylindrical shape of the wireframe structure 325 is a round cylinder. In some embodiments, the cylindrical shape of the wireframe structure is a non-round cylinder. For example, the cylindrical shape is a cylinder with an elliptical cross-section.

[0052] In some embodiments, the prosthesis 300 may also include a plurality of fins (similar to the fins 130 illustrated in the prosthesis embodiment 100) extending radially from the post 320 at or near where the post meets the proximal surface 312. In some embodiments, the plurality of fins may be located where the post meets the proximal surface 312 and extend radially along the proximal surface. In some embodiments, the plurality of fins are located near where the post meets the proximal surface, but do not contact the proximal surface 312.

[0053] In some embodiments, the prosthesis 300 may further include a plurality of openings 340 disposed between the post 320 and the periphery of the base body for receiving one or more bone screws to secure the prosthesis 300 to the glenoid. Each of the plurality of openings 340 extends through the base body 310 from the distal surface 311 to the proximal surface 312.

[0054] In some embodiments, the prosthesis 300 can further include a modular bone augment 50 that is configured to slide over the post 320 and abut the proximal surface 312 of the baseplate body 310 .

[0055] refer to Figure 5A, a prosthesis 400 for attachment to a glenoid cavity according to another embodiment is provided. The prosthesis 400 includes a base body 410, which is a unitary metal structure. The base body 410 includes a distal surface 411, a proximal surface 412, and a post 420, which extends from the proximal surface 412. In this embodiment, the post 420 includes a hollow generally cylindrical structure defining an internal volume. The hollow generally cylindrical structure of the post 420 includes a plurality of openings 429, which provide access to the internal volume. The hollow cylindrical structure of the post 420 also includes an opening 428 located at the proximal end of the post 420. The proximal end of the post 420 is the end farthest from the base body 410. The features of the base body 410 and the post 420 are described herein, which provide orientation stability for a modular bone graft used with the prosthesis 400.

[0056] In some embodiments, the unitary metal structure of baseplate body 410 may be manufactured by an additive manufacturing process such as 3-D printing.Post 420 is configured to be disposed in a complementary hole or recess prepared in the glenoid to assist in attaching prosthesis 400 to the glenoid.

[0058] In some embodiments, the substrate body 410 may include an opening 428 extending through the substrate body 410 and through the entire length of the post 420, which provides access to the interior volume of the post 420. The hollow structure of the post 420 may include a plurality of openings 429, which also provide access to the interior volume of the post 420. The hollow post 420 may be implanted in the glenoid by impacting the hollow post 420 into the glenoid, which will require minimal bone preparation. When the prosthesis 400 is impacted into the glenoid, the bone material will fill the interior volume of the hollow post 420. After the prosthesis 400 is fully implanted, the plurality of openings 429 allow the bone tissue inside the post 420 and outside the post 420 to grow into each other by bridging through the openings 429, thereby strengthening the fixation of the prosthesis 400 in the bone.

[0059] In some embodiments, the interior volume of the column 420 and the opening 429 may be filled with a porous material, such as ADAPTIS® from Wright Medical Group NV. TM Such filling of the internal volume may be accomplished through an opening 428 located at the proximal end of the post 420 .

[0060] In some embodiments, the prosthesis 400 may also include a plurality of fins (similar to the fins 130 shown in the prosthesis embodiment 100) extending radially from the posts 420 at or near where the posts meet the proximal surface 412. In some embodiments, the plurality of fins may be located where the posts meet the proximal surface 412 and extend radially along the proximal surface 412.

[0061] In some embodiments, the prosthesis 400 may further include a plurality of openings 440 disposed between the post 420 and the periphery of the base body. Each of the plurality of openings 440 extends through the base body 410 from the distal surface 411 to the proximal surface 412 for receiving one or more screws to help secure the prosthesis 400 to the glenoid.

[0062] In some embodiments, the prosthesis 400 can further include a bone graft 50 that is configured to slide over the post 420 and abut the proximal surface 412 of the baseplate body 410 .

[0063] refer to Figure 5B and Figure 5C , a prosthesis 500 for attachment to a glenoid according to another embodiment is provided. The prosthesis 500 includes a base body 510, which is a unitary metal structure. The base body 510 includes a distal surface 511, a proximal surface 512, and a post 520, which extends from the proximal surface 512.

The hollow cylindrical structure of the post 520 also includes an opening 528 located at the proximal end of the post 520. The proximal end of the post 520 is the end farthest from the base body 510. The features of the base body 510 and the post 520 are described herein, which provide orientation stability for a modular bone graft used with the prosthesis 500.

[0064] In some embodiments, the unitary metal structure of baseplate body 510 can be manufactured by an additive manufacturing process such as 3-D printing.Post 520 is configured to be disposed in a complementary hole or recess prepared in the glenoid to assist in attaching prosthesis 500 to the glenoid.

[0065] In some embodiments, the hollow structure of the column 520 may have a generally cylindrical shape. In some embodiments, the hollow structure of the column 520 may have a circular cylindrical shape. In some embodiments, the hollow structure of the column 520 may have a non-circular cylindrical shape.

[0066] In some embodiments, the substrate body 510 may include an opening 528 that extends through the substrate body 510 and through the entire length of the column 520, which provides access to the interior volume of the column 520. The hollow structure of the column 520 may include a plurality of openings 529 that also provide access to the interior volume of the column 520. The hollow column 520 can be implanted in the glenoid by impacting the hollow column 520 into the glenoid, which will require minimal bone preparation. When the prosthesis 500 is impacted into the glenoid, bone material will fill the interior volume of the hollow column 520. After the prosthesis 500 is fully implanted, the plurality of openings 529 allow bone tissue inside the column 520 and outside the column 520 to grow into each other by bridging through the openings 529, thereby strengthening the fixation of the prosthesis 500 in the bone. Figure 5C As shown, the edge 521 of the hollow post 520 can be angled relative to the longitudinal axis L of the post 520 such that the edge 521 can facilitate initial protrusion into the glenoid when the hollow post 520 is impacted into the bone.

The prosthesis 800 includes a base body 810, which is a unitary metal structure. The base body 810 includes a distal surface 811, a proximal surface 812, and a post 820 extending from the proximal surface 812.

[0072] In this embodiment, the proximal surface 812 and the post 820 include a porous surface portion that serves as a scaffold to promote bone ingrowth after the prosthesis 800 is implanted in the glenoid cavity. As discussed below, the porous surface portion can also interact with a modular bone augmentation made of bone graft to promote bone ingrowth. For example, Figure 6B As shown, the proximal surface 812 may be provided with a porous surface portion 812a as a surface layer. As shown in the illustrated example, the porous surface portion 812a may cover most, if not all, of the proximal surface 812. The column 820 has an outer surface and includes a plurality of porous surface portions 827 protruding from the outer surface of the column. As shown, each of the protruding porous surface portions 827 may extend along a majority of the length of the column 820 separated by some spaces 829, but in other embodiments, the specific pattern and shape of the plurality of porous surface portions 827 may vary. The protruding porous surface portions 827 cooperate with the modular bone augment that slides over the column 820 to provide orientation stability for the modular bone augment. In other words, the protruding porous surface portions 827 cooperate with the mating surface of the modular bone augment to prevent the bone augment from rotating around the column 820. As will be discussed further below, the modular bone augment is constructed with a mating surface that cooperates with the protruding porous surface portions 827.

[0073] The porous surface portions 812a and 827 may be formed of the same metal material and may be formed simultaneously by an additive manufacturing process.The post 820 is configured to be disposed in a complementary hole or recess prepared in the glenoid to assist in attaching the prosthesis 800 to the glenoid.

[0074] In some embodiments, the prosthesis 800 may also include a plurality of fins (similar to the fins 130 illustrated in the prosthesis embodiment 100) extending radially from the post 820 at or near where the post meets the proximal surface 812. In some embodiments, the plurality of fins may be located where the post meets the proximal surface 812 and extend radially along the proximal surface. In some embodiments, the plurality of fins are located near where the post meets the proximal surface, but do not contact the proximal surface 812.

[0075] In some embodiments, the prosthesis 800 may also include a plurality of openings 840, 840a disposed between the post 820 and the periphery of the base body for receiving one or more bone screws to secure the prosthesis 800 to the glenoid. Each of the plurality of openings 840, 840a extends through the base body 810 from the distal surface 811 to the proximal surface 812. In some embodiments, some or each of the plurality of openings may be configured differently to accommodate different types of screws. For example, in the illustrated example, two holes 840 are configured to receive multidirectional screws without olives, while two holes 840a are configured to receive multidirectional screws with olives.

[0076] In some embodiments, the prosthesis 800 may include one or more additional openings or recesses 830 configured to receive instruments for holding the prosthesis 800. Fig. 6A In the illustrated example shown, the base plate body 810 is provided with two oblong holes 830 for receiving the ends of a clamp that may be used, for example, by a surgeon to hold a prosthesis during surgery.

[0077] refer to Figure 6C In some embodiments, the post 820 can be configured with a hole or channel 828 that facilitates positioning of the joint component (such as the glenosphere component 700 (see FIG. 1 ) when the joint component is attached to the baseplate body 810. Figure 5D )) is aligned with the prosthesis 800. The structure and function of the channel 828 are the same as the channel 128 provided in the post 120 of the prosthesis embodiment 100 described above.

[0078] Similarly, channel 828 can be a blind hole that extends to a predetermined depth in column 820 so that a guide pin inserted into portion A of channel 828 extends an appropriate amount out of channel 828 at distal surface 811 and provides a guide function for joint component 700.

[0079] In some embodiments, the channel 828 may extend through the entire length of the column 820, such that the channel 828 is open at the distal surface 811 and at the proximal end of the column 820. In such an embodiment, the channel 828 may be constructed with two portions A and B, wherein portion A is the portion that is open at the distal surface 811 and receives the guide pin. Portion B may have a smaller diameter than portion A, such that the guide pin is too large to fit into the smaller diameter portion B. This configuration prevents the guide pin from exiting at the proximal end of the column 820 and entering the patient's bone. Additionally, having the channel 828 open at both ends allows for the discharge of debris and fluids generated during the manufacturing process of drilling the channel 828.

[0080] refer to FIG. 7A to FIG. 7DIn some embodiments, the prosthesis 800 may also include a modular bone augment configured to slide over the post 820 and abut the porous surface portion 812a of the base body 810. As discussed below, the modular bone augment may be formed of a bone graft material or a porous metal material. FIG. 7A to FIG. 7D In the illustrated example, the bone augment 50A is a porous metal augment. The bone augment 50A is constructed with a hole for receiving the post 820, so that the bone augment 50A can slide over the post 820 and contact the porous surface 812a of the substrate body 810. The inner surface of the hole in the bone augment 50A for receiving the post 820 is configured as a mating surface that cooperates with the raised porous surface portion 827 on the post 820 and provides orientation stability for the bone augment 50A by preventing or hindering the bone augment 50A from rotating around the post 820. For example, the inner surface of the hole in the bone augment 50A for receiving the post 820 can be configured to have a surface profile that is a negative shape (i.e., a mirror image) of the raised porous surface portion 827, so that the bone augment 50A can slide over the post 820 by sliding over in a longitudinal direction parallel to the longitudinal axis L of the prosthesis 800 (see Figure 6C However, once the bone augment 50A is slid over the post 820, the raised porous surface portions 827 and the complementary mating surfaces of the bone augment 50A fit like gear teeth, and the engagement between the raised porous surface portions 827 and the mating surfaces of the bone augment 50A prevents the bone augment 50A from rotating about the post 820.

[0081] Bone augment 50A can be constructed with one or more cutouts 57 for accommodating screws to be inserted through holes 840, 840a. Bone augment 50A has a bone engaging surface 50A-1, the surface contour of which is configured to have a shape that will properly fill the defective void in the glenoid. As previously mentioned, in some embodiments, the bone engaging surface 50A-1 of bone augment 50A can be configured with a patient-matched surface contour for the condition of the glenoid of a particular patient.

[0082] In some embodiments, the post 820 can be configured with a hole or channel 828 that can help align the articulation component with the prosthesis 800 when the articulation component is attached to the baseplate body 810. The channel 828 extends from the distal surface 811 into the post 820 along the longitudinal axis L of the post 820. The structure of the channel 828 can be the same as the channel 128 in the post 120 of the prosthesis embodiment 100, and the channel 828 of the prosthesis 800 receives the guide pin in the same manner as described above for the channel 128 in the post 120.

In this embodiment, the bone reinforcement portion 50A and the post 820 are integrally formed as part of the unitary metal structure of the base body 810.

[0084] The metal bone reinforcement portion 50A of the proximal surface 812 extends away from the distal surface 811 and defines a bone engaging surface 50A-1 spaced apart from the distal surface 811. The post 820 includes an outer surface and a plurality of porous surface portions 827 that may protrude from the outer surface of the post. In some embodiments, the porous surface portions 827 may be flush with the outer surface of the post 820.

As shown, each of the raised porous surface portions 827 may extend along a majority of the length of the post 820 separated by some spaces 829, but in other embodiments, the specific pattern and shape of the plurality of porous surface portions 827 may vary.

[0086] refer to Figure 7C , the bone engaging surface 50A-1 is oriented at an oblique angle relative to the distal surface 811 of the base plate body 810. In some embodiments, the oblique angle may be between 10 and 30 degrees. In some embodiments, the oblique angle may be between 15 and 25 degrees.

[0087] In some embodiments, the bone engaging surface 50A-1 is a non-flat surface. In some embodiments, the bone engaging surface 50A-1 is a spherical surface. In some embodiments, the radius of curvature of the spherical surface is in the range of 30 mm to 50 mm. In some embodiments in which the bone engaging surface 50A-1 is a spherical surface, the spherical surface 50A-1 is oriented at an oblique angle between 10 and 30 degrees relative to the distal surface 811. In some embodiments, the oblique angle may be between 15 and 25 degrees.

[0088] refer to Figure 7C For a bone engaging surface 50A-1 having a spherical curvature, the oblique orientation of the surface is defined as when the angle from Figure 7CThe edge E is shown oriented at an angle relative to the distal surface 811 when viewed from the side. The edge E is defined as the edge where the bone engaging surface 50A-1 intersects the side surface 50A-2 of the bone augmentation portion 50A.

[0089] In some embodiments of the prosthesis 800 having an integrally bonded metal bone augmentation portion 50A, a plurality of openings 840, 840a may be provided between the post 820 and the periphery of the base body, wherein each of the plurality of openings extends through the base body 810 from the distal surface 811 to the proximal surface 812 for receiving one or more screws. In some embodiments, the prosthesis 800 may also include one or more additional openings or recesses 830 configured to receive instruments for holding the prosthesis 800. Figure 7B In the illustrated example shown, the base plate body 810 is provided with two oblong holes 830 for receiving the ends of a clamp that may be used, for example, by a surgeon to hold a prosthesis during surgery.

[0090] In some embodiments, the post 820 has a longitudinal axis and can include a channel 828 extending from the distal surface 811 into the post and extending along the post longitudinal axis L. The channel 828 can be identical in structure to the channel 128 in the post 120 of the prosthesis embodiment 100, and the channel 828 of the prosthesis 800 receives a guide pin in the same manner as described above for the channel 128 in the post 120.
