Abstract

A humeral component of a prosthetic assembly that is used in repairing or reconstructing a joint between a humerus and a scapula that includes a stemless portion and a liner portion. The liner portion is attached to the stemless portion and adapted to receive a ball portion of a cooperating “reverse” type glenoid component.

Description

FIELD OF DISCLOSURE

This disclosure relates generally to orthopedic prostheses for use in reconstruction of a human shoulder joint. More particularly, the disclosure relates to such a prosthesis that is adapted for use in repairing or reconstructing an unstable shoulder joint, and where it is desirable to preserve as much metaphyseal bone as possible.

BACKGROUND OF THE DISCLOSURE

The human shoulder joint provides the broadest range of motion of any joint in the body and consists of the proximal end of the humerus or the humeral head, and it articulates with a structure called the glenoid fossa on the lateral end of the scapula. The ability to have the full range of glenohumeral motion is predicated on the stabilization of the head of the humerus on the glenoid fossa by a functioning rotator cuff, consisting of the supraspinatus, infraspinatus, subscapularis and teres minor, and the static stabilizers, consisting of the capsule, labrum, glenohumeral ligaments, and the negative intraarticular pressure.

When the shoulder joint becomes unstable with superior escape of the humeral head due to rotator cuff tear arthropathy, a failed hemi-arthroplasty, or other conditions where the joint becomes unbalanced leading to asymmetric glenoid wear, the shoulder joint will need to be reconstructed with a reverse shoulder prosthesis. Such reconstruction can restore some degree of range of motion to the unstable joint by stabilizing the center of rotation of the humerus and allowing the deltoid muscle to more efficiently elevate the humerus, thus allowing some basic activities of daily living to be performed. Current reverse shoulder prostheses consist of a humeral component with a stem that fits down the intramedullary canal which limits placement of the implant. In contrast, a stemless reverse allows more variability in placement on the surgical cut, as well as decreasing the amount of bone that has to be removed.

It is therefore desirable if an implant were available that would provide a reverse shoulder prosthesis without the stem portion. It would also be desirable if an implant could be provided that would allow repair of the joint while reducing the amount of bone needing to be removed from the intramedullary canal. It would also be desirable if such an implant could be provided that would allow for adding bone substitute material when there is a lack of adequate bone quality in the proximal end of the humerus.

Among the advantages of the preferred embodiments of the disclosure is that they provide a prosthetic component that can be implanted with minimal bone removal. Another advantage of the preferred embodiments of the disclosure is that they provide a prosthesis that has a greater freedom of placement on the surgical cut of the humeral head. Still another advantage of the preferred embodiments of the disclosure is that they provide a prosthesis that can be used to repair a shoulder joint without the need for adding bone graft material when there is a lack of adequate bone quality in the proximal end of the humerus. Yet another advantage of the preferred embodiments of the disclosure is that they allow for placement of the prosthesis in an inlay fashion to reduce off-axis forces being place on the implant.

Additional objects and advantages of this disclosure will become apparent from an examination of the drawings and the ensuing description.

Thus, the term “attached” or “coupled”, and grammatically related terms includes releasably attaching or fixedly attaching two or more elements and/or devices in the present or absence of one or more other elements in between. As used herein, the terms “proximal” and “distal” are used to describe opposing axial ends of the particular elements or features being described in relation to anatomical placement.

While the systems, methods, and components described herein are exemplified by systems and methods for humeral prostheses, the systems, methods, and components described and illustrated herein can be used to treat any suitable ailment or joint within the body of an animal, including, but not limited to, humans. Skilled artisans will be able to select a suitable ailment and/or joint within the body of an animal to utilize a system and/or method described herein according to a particular embodiment based on various considerations, including the type of ailment and/or the structural arrangement at a treatment site. Example joints considered suitable to utilize a system, method, and/or component described herein include, but are not limited to, the shoulder joint, the elbow joint, the knee joint, the hip joint, and the ankle joint.

FIG. 1 is an anterior view of the bones of a normal human shoulder joint. As shown therein, the humerus 100 includes the humeral head 102 that forms the “ball” portion of this ball-and-socket joint. The humeral head 102 is in contact with the glenoid fossa 104 of scapula 106 which forms the “socket” portion of the shoulder joint. Additional structures of the scapula include the coracoid process 110, and the acromion 112. The humerus is held in place against the scapula by passive suspension with the aid of various ligaments (not shown) and active suspension in which the rotator cuff muscles, including the supraspinatus, infraspinatus, Teres Minor and Subscapularis, help to balance the head of the humerus in the glenoid socket against the upward pull of the deltoid muscle.

Arthritis, bone disease or injury can alter the smooth functioning of the shoulder joint. In primary joint repair, the head of the humerus is typically removed and a prosthetic stem is implanted into the humerus. A prosthetic ball is attached to this stem and a prosthetic socket is implanted in the glenoid fossa so as to articulate with the prosthetic ball. However, some conditions can make repair or reconstruction that maintains the normal spatial relationship between the “ball” and the “socket” of the joint impossible. Under these circumstances, repair or reconstruction of the joint using a “reverse” prosthesis, as seen in FIG. 2, employs a stemless shell 114 and a liner 116. Preferably, the stemless shell 114 is comprised of titanium or another biocompatible metal, and the liner 116 is comprised of plastic, ceramic, or another biocompatible material. On the glenoid side, a baseplate 118 is adapted to be attached to the glenoid portion of the scapula 106 using a plurality of fasteners 120. The ball 122 is adapted to attach to the baseplate 118, and it articulates with the liner 116 that attaches to the stemless shell 114, as shown in FIG. 2.

FIGS. 3-91 illustrate humeral components for use in a “reverse” type shoulder joint repair or reconstruction according to the disclosure so that the shoulder joint may be stabilized in such a way that normal joint functions can be maintained.
