1. TITLE OF THE INVENTION:
ORTHOPEDIC IMPLANT
2. APPLICANT:
Meril Corporation (I) Private Limited, an Indian company of the address Survey No. 135/139, Muktanand Marg, Bilakhia House, Pardi, Vapi, Valsad-396191 Gujarat, India.

The following specification particularly describes the invention and the manner in which it is to be performed:

FIELD OF INVENTION
[1] The present disclosure relates to a medical implant. More particularly, the present disclosure relates to an orthopedic implant.
BACKGROUND OF INVENTION
[2] Human body includes numerous ball and socket joints which, allow smooth movement in the bones, for example, a shoulder joint (glenohumeral joint), a hip joint. The ball and socket joint allows for a wide range of motion including rotation, lifting, and swinging movements.
[3] Taking an example of a shoulder joint, also known as a glenohumeral joint, the glenohumeral joint has a great mobility but is also relatively unstable compared to other joints, making it more susceptible to dislocations and injuries. There are several medical conditions associated with glenohumeral joints including inflammation, instability due to loosening of the joints, compression of the rotator cuff, etc. causing pain and stiffness. Osteoarthritis and/or rheumatoid arthritis can affect the glenohumeral joint, leading to pain, stiffness, and reduced motion.
[4] Patients suffering from such medical conditions typically undergo an arthroplasty procedure. In this procedure, damaged or diseased parts of the shoulder joint are replaced with artificial parts (prosthesis). In a reverse arthroplasty procedure, the ball is placed on a socket side of a joint. The socket is then placed on the arm side, where it is supported by a metal stem in the arm bone (humerus) (as shown in Fig. 1).
[5] However, conventional implants heavily suffer from problems such as loose locking, instability, inefficient load distribution, and wear and tear. The misalignment and/or loosening of the shoulder prosthesis may also lead to improper functioning of the shoulder prosthesis and compromising rotational stability of the shoulder joint, which is essential for optimal performance and patient satisfaction. The misalignment can, in turn, cause uneven mechanical load distribution in the shoulder joint leading to the rise of several complications and diseases such as osteolysis.
[6] Thus, there arises a need for an implant that overcomes the problems associated with conventional implants.

[20] Although the operations of exemplary embodiments of the disclosed method may be described in a particular, sequential order for convenient presentation, it should be understood that the disclosed embodiments can encompass an order of operations other than the particular, sequential order disclosed. For example, operations described sequentially may in some cases be rearranged or performed concurrently. Further, descriptions and disclosures provided in association with one particular embodiment are not limited to that embodiment, and may be applied to any embodiment disclosed herein. Moreover, for the sake of simplicity, the attached figures may not show the various ways in which the disclosed system, method, and apparatus can be used in combination with other systems, methods, and apparatuses.
[21] Furthermore, the described features, advantages, and characteristics of the embodiments may be combined in any suitable manner. One skilled in the relevant art will recognize that the embodiments may be practiced without one or more of the specific features or advantages of a particular embodiment. In other instances, additional features and advantages may be recognized in certain embodiments that may not be present in all embodiments. These features and advantages of the embodiments will become more fully apparent from the following description and apportioned claims, or may be learned by the practice of embodiments as set forth hereinafter.
[22] The present disclosure relates to a prosthesis (or implant). The implant may be used in a reverse shoulder arthroplasty (or a reverse shoulder replacement surgery). In an embodiment, the implant includes a bearing seated on a tray. The bearing and the tray are coupled together via a locking mechanism. The locking mechanism between the bearing and the tray ensures stability, secure fit, efficient load distribution, ease of implantation, minimized wear and tear, and enhanced durability. The locking mechanism of the present disclosure is vital for the performance, longevity, and success of implants, contributing significantly to patient outcomes and quality of life post-surgery. The locking mechanism ensures that the bearing and the tray are securely locked in place, thereby minimizing the risk of dislocation of the implant components. This stability is crucial for the proper functioning and longevity of the implant. This reduces stress concentrations, which can otherwise lead to wear and tear or even failure of the implant over time.
[23] The locking mechanism further reduces micromotion between the bearing and the tray thereby minimizing wear and particle generation. This is important for reducing the risk of osteolysis (bone resorption) caused by wear particles. The locking mechanism enhances the overall durability and lifespan of the implant by maintaining a secure connection between the bearing and the tray, even under repetitive stresses and movements. Thus, the present disclosure contributes to better postoperative comfort and function for the patient.
[24] In an embodiment, the implant is used as a trial implant during an arthroplasty procedure. For example, the bearing is a temporary component used during an arthroplasty to mimic the final bearing that will be implanted. This will allow the surgeon to test the stability and overall fit of the prosthesis. This helps in making necessary adjustments before the final implantation. Similarly, the tray is a temporary component used during arthroplasty to test and ensure the correct fit, alignment, and functionality of the prosthesis before the final components are implanted. The tray mimics the design and dimensions of the final tray, allowing the surgeon to make necessary adjustments during the procedure. Thus, the present disclosure contributes to better postoperative comfort and function for the patient, as a stable and well-functioning implant will allow for smoother, pain-free movement.
[25] In an embodiment, the implant replaces the damaged portion of the humeral bone of the glenohumeral joint.
[26] Now, referring to figures, Fig. 2a depicts an assembled view of an implant 100 and Fig. 2b depicts an exploded view of the implant 100, according to an embodiment of the present disclosure. In an embodiment, the implant 100 replaces the injured or damaged head of the humerus bone of a glenohumeral joint. The implant 100 has a proximal end 100a and a distal end 100b. The implant 100 includes a bearing 110 and a tray 120. The bearing 110 is coupled to the tray 120 via a locking mechanism, which has been explained later. Details of the bearing 110 are explained in the context of Figs. 3a - 3b while the details of the tray 120 are explained in the context of Fig. 4a - 4b.
[27] The bearing 110 (as shown in Fig. 2a) is disposed at the proximal end 100a of the implant 100. The bearing 110 may be made of any biocompatible poly material or metal. The metal that may be used in making the bearing 110 may include, without limitation, titanium, aluminum alloy, cobalt chromium (CoCr), stainless steel (SS316), high nitrogen stainless steel (HNSS) etc., or a combination thereof. The poly material includes, without limitation, medical grade plastics (high density polyethylene), high-performance polyphenylsulfone (PPSU) resin. In an exemplary embodiment, the bearing 110 is made of high-performance polyphenylsulfone (PPSU) resin Radel R-500. The dimensions of the humeral bearing 110 may vary according to or based upon the anatomy of the patient and/or of the patient population in consideration. The bearing 110 is coupled with the tray 120 via a secure locking mechanism as described later, thereby leading to a secure attachment of the bearing 110 with the tray 120 and ensuring patient’s safety.
[28] Figs. 3a – 3b depict various views of the bearing 110, according to an embodiment. Referring to Fig. 3a, the bearing 110 has a tubular structure, and a top end 110a and a bottom end 110b.

The curvature of the top surface 110d of the bearing 110 is configured to receive at least a portion of a glenoid component (not shown). The bottom surface 110c is coupled with the tray 120 (described later).
[30] The body 112 of the bearing 110 includes a plurality of carvings 110e (hereinafter, carvings 110e) provided on an outer surface of the body 112. The carvings 110e have a pre-defined shape such as, without limitation, circular, oval, rectangular, polygonal, square, oblong, etc. In an exemplary embodiment, the carvings 110e have an oblong shape. The carvings 110e may be blind or through-carvings. The carvings 110e help in providing a better grip to a surgeon holding the implant 100 during a surgical procedure.
[31] Referring to Fig. 3b, the raised platform 111 may be quadrilateral, circular, cone-shaped, arc-shaped, spherical, etc. In an exemplary embodiment, the raised platform 111 is generally circular. The raised platform 111 extends away from the bottom surface 110c of the body 112 towards the bottom end 110b of the bearing 110. In an embodiment, the raised platform 111 is designed such that the raised platform 111 defines a gap 111b between the raised platform 111 and the body 112. In an embodiment, the height of the raised platform 111 varies with respect to the patient anatomy. The raised platform 111 helps in coupling the bearing 110 with the tray 120. In an embodiment, the raised platform 111 forms an integrated structure with the body 112. In another embodiment, the raised platform 111 may be a separate component coupled to the body 112 using, for example, bonding, or any other suitable coupling technique known in the art.
[32] The raised platform 111 includes at least one curved end. In an embodiment, the raised platform 111 includes a first curved end 113a and a second curved end 113b provided at two opposite ends of the raised platform 111.

The depicted locations of the first tab 113c and the second tab 113d are merely exemplary and the first tab 113c and the second tab 113d may be provided at any other location as needed. The first tab 113c and the second tab 113d may be circular, rectangular, oval, spherical, conical, etc. In an exemplary embodiment, the first tab 113c and the second tab 113d are rectangular. Each of the first tab 113c and the second tab 113d defines two side walls (not shown) and a longitudinal wall (not shown). The first tab 113c and the second tab 113d help in coupling the bearing 110 with the tray 120.
[34] The at least one slot 115 is provided on the raised platform 111. The at least one slot 115 extends longitudinally for at least a partial width of the raised platform 111. In the depicted embodiment, the raised platform 111 is provided with one slot 115 extending longitudinally for the entire width of the raised platform 111. The slot 115 is disposed towards the first curved end 113a. The slot 115 is disposed at a specific distance from the first curved end 113a. The slot 115 helps in coupling the bearing 110 with the tray 120. It should be understood that more than one slot 115 may be provided on the raised platform 111 without deviating from the scope of the present disclosure.
[35] Figs. 4a - 4b depict the tray 120, in accordance with an embodiment. The tray 120 is disposed at the distal end 100b of the implant 100 (as shown in Fig. 2). The tray 120 may be made of any biocompatible poly material or metal. The metal that may be used in making the tray 120 includes, without limitation, titanium, cobalt chromium (CoCr), stainless steel 316 (SS316), high nitrogen stainless steel (HNSS), aluminum alloy, etc., or a combination thereof. The poly material includes, without limitation, medical grade plastics (high density polyethylene), high performance polyphenylsulfone (PPSU) resin. In an exemplary embodiment, the tray 120 is made of high-performance polyphenylsulfone (PPSU) resin Radel R-500. The dimensions of the tray 120 may vary according to or based upon the anatomy of the patient and/or of the patient population in consideration. The tray 120 replaces the diseased portion of the humeral head of the patient.
[36] The tray 120 includes has top end 120a, and a bottom end 120b, and includes a top surface 120c as depicted in the Fig. 4a.

The wall 123 has a first end 123a1 and a second end 123a2. The wall 123 surrounds the base 121 and extends from the base 121 towards the top end 120a of the tray 120. The wall 123 defines a space configured to receive the raised platform 111 of the bearing 110. The wall 123 may have a uniform or non-uniform thickness. In the depicted embodiment, the wall 123 has a non-uniform thickness. The wall 123 may be open from the first end 123a1 of the wall 123 such that the wall 123 forms a shape such as, a U-shape, a C-shape or a horse-shoe shape. In other words, the wall 123 includes an opening at the first end 123a1 of the wall 123. This allows the bearing 110 to be slid into or out of the tray 120 to couple or decouple with the tray 120. In an embodiment, the tray 120 includes an extension 130. The extension 130 extends from a bottom surface (not shown) of the tray 120 towards the bottom end 120b. In an embodiment, the extension 130 is disposed at the center of the bottom surface of the tray 120. It should be understood though that the extension 130 may be disposed at any other position on the bottom surface of the tray 120 without deviating from the scope of the teachings of the present disclosure.

The extension 130 may be made of a material including, but not limited to, titanium, cobalt chromium (CoCr), stainless steel 316 (SS316), high nitrogen stainless steel (HNSS). In an exemplary embodiment, the extension 130 is made of titanium. The dimensions of the extension 130 may vary according to or based upon the anatomy of the patient and/or of the patient population in consideration. The extension 130 is inserted in the humerus (not shown) of a patient and is provided for coupling the implant 100 to the humerus. In an embodiment, the extension 130 and the tray 120 form an integrated structure. In another embodiment, the extension 130 may be a separate component coupled to the tray 120 using, for example, bonding or any other suitable coupling technique.
[37] In an embodiment, the wall 123 includes the curved end 123a disposed at the second end 123a2 of the wall 123, the second end 123a2 being opposite to the first end 123a1 of the wall 123 (as shown in Figs. 4a - 4b). It should be understood that the wall 123 may include more than one curved end 123a. The curved end 123a of the tray 120 is configured to mate with the first curved end 113a of the bearing 110. Further, the location, shape and dimensions of the curved end 123a correspond to the shape and dimensions of the first curved end 113a of the bearing 110.
[38] The first slab 123b and the second slab 123c extend inwards from the inner periphery of the wall 123 for a pre-defined distance. It should be understood that more than two slabs may be provided on the wall 123. In the depicted embodiment, the first slab 123b and the second slab 123c are arc shaped, though the first slab 123b and the second slab 123c may have any other shape. In the depicted embodiment, the first slab 123b and the second slab 123c form an integrated structure with the wall 123. In another embodiment, the first slab 123b and the second slab 123c may be separate components coupled to the wall 123 using, for example, welding, brazing or soldering, bolting or screwing, press fit or any other suitable coupling technique.
[39] The first slab 123b includes the first groove 123d extending longitudinally for at least a partial length of the first slab 123b at and the second slab 123c includes the second groove 123e extending longitudinally for at least a partial length of the second slab 123c. The first groove 123d and the second groove 123e at the inner depth. The first groove 123d and the second groove 123e are configured to mate with the first tab 113c and the second tab 113d, respectively, of the bearing 110, forming a snap-fit lock. Further, the shape, dimensions, and the disposition of the first groove 123d and the second groove 123e correspond to that of the first tab 113c and the second tab 113d, respectively.
[40] The at least one ridge 125 is provided on base 121. Each of the at least one ridge 125 is configured to mate with a corresponding slot 115 of the at least one slot 115 forming a tight snap-fit coupling. In the depicted embodiment, the tray 120 includes one ridge 125 as shown in Figs. 4a – 4b. The position, shape and dimensions of the ridge 125 correspond to that of the slot 115 of the bearing 110. In an embodiment, the ridge 125 is provided towards the curved end 123a at a pre-defined distance from the curved end 123a. Though the depicted embodiment shows a single ridge 125, it should be understood that the tray 120 may be provided with more than one ridges 125 with each ridge 125 configured to mate with a respective slot 115 of more than one slot 115 provided on the bearing 110.
[41] To assemble the implant 100, the bearing 110 is coupled to the tray 120 at the top end 120a of the tray 120. Specifically, the bearing 110 is positioned at the opening of the wall 123 of the tray 120 such that the first tab 113c and the second tab 113d of the bearing 110 align with the first groove 123d and the second groove 123e, respectively. The bearing 110 is then pushed further until the raised platform 111 of the bearing 110 is seated on the base 121 of the tray 120. At this stage, the first tab 113c and the second tab 113d of the bearing 110 mate with the first groove 123d and the second grove 123e, respectively, of the tray 120. The first tab 113c coupled with the first groove 123d and the second tab 113d coupled with the second groove 123e for snap-fit lock. This prevents rotational motion of the bearing 110. Further, the ridge 125 of the tray 120 mates with the slot 115 of the tray 120 forming a tight snap-fit coupling. The aforesaid coupling between the ridge 125 and the slot 115 prevents the bearing 110 from coming out of the opening of the wall 123. In addition, the first curved end 113a of the bearing 110 mates with the curved end 123a of the tray 120, thereby coupling the bearing 110 with the tray 120. The assembled implant 100 (as shown in Fig. 5) may then be implanted at a prepared site. The raised platform 111, the first curved end 113a, the first tab 113c, the second tab 113d and the slot 115 of the bearing 110 along with the curved end 123a, the first groove 123d, the second groove 123e, and the ridge 125 of the tray 120 define a locking mechanism of the implant 100. The locking mechanism prevents any movement (longitudinal and rotational) of the bearing 110 with respect to the tray 120, thereby eliminating the chances of dislocation of the bearing 110 from the tray 120.
[42] It is to be noted from the aforesaid description that the first curved end 113a and the curved end 123a, the first tab 113c and the first groove 123d, the second tab 113d and the second groove 123e, and the slot 115 and the ridge 125 function in pairs. Thus, the disposition, shape and dimensions of two corresponding mating components of each such pair are complementary. Any alteration in disposition, shape or dimension of any one mating component in such a pair is to be replicated to the corresponding mating component of that pair.
[43] According to an embodiment, the raised platform 111, the first curved end 113a, the first tab 113c, the second tab 113d, the slot 115 of the bearing 110 may be formed by laser cutting or carving the bearing 110 using any optimal machining process. Similarly, the curved end 123a, the first slab 123b, the second slab 123c, the first groove 123d, the second groove 123e, the ridge 125 of the tray 120 may be formed by laser cutting, or carving the tray 120 using any optimal machining process. Though, in the depicted embodiment, various components of the bearing 110 and the tray 120 are described as integrated structures, it should be understood that in another embodiment, one or more components of the bearing 110 and the tray 120 may be separate components coupled to the bearing 110 and tray 120 (or any components thereof) using a suitable coupling mechanism. For example, the raised platform 111 may be bonded or welded to the bearing 110. Similarly, the first slab 123b and the second slab 123c may be bonded or welded to base 121 (or to the wall 123).
[44] The scope of the invention is only limited by the appended patent claims. More generally, those skilled in the art will readily appreciate that all parameters, dimensions, materials, and configurations described herein are meant to be exemplary and that the actual parameters, dimensions, materials, and/or configurations will depend upon the specific application or applications for which the teachings of the present invention is/are used. , Claims:WE CLAIM:
