Abstract

A method of making a metal-backed acetabular implant includes roughening a surface of a metallic integument and compression molding a bearing to the surface after the roughening step.

Description

    FIELD OF THE INVENTION
  • The present invention relates generally to the field of orthopaedics, and, more particularly, to a method of making a metal-backed acetabular implant for a hip prosthesis.
  • BACKGROUND
  • A conventional hip prosthesis is primarily composed of an acetabular implant and a femoral implant. The acetabular implant typically includes a generally hemispherical dome-like or cup-like metallic shell secured within the acetabulum and a dome-like or cup-like plastic or ceramic bearing secured within the shell. Accordingly, the shell typically includes an exterior configured to be anchored into the acetabulum and further typically includes an interior configured to align and retain the bearing, while the bearing typically includes an exterior configured to cooperate with the interior of the shell to align and secure the bearing within the shell and further typically includes an interior defining an artificial hip socket (which may or may not be off-centered from the exterior of the bearing, depending on the particular design). The femoral implant typically includes an elongated metallic spike or post at one end and a metallic ball at the other. The post is typically configured to be anchored into the distal femoral medullary canal and the ball is typically configured to insert into the artificial socket. Pivotal freedom of the ball within the socket allows articulation of the prosthetic joint.
  • A substantial dislocation and/or rotation of the bearing relative to the shell can potentially degrade the biomechanics and/or wear characteristics of the conventional hip prosthesis. Historically, balancing the needs for effective bearing retention with competing desires for design simplicity and versatility has been challenging.
  • SUMMARY OF THE INVENTION
  • The present invention provides a method of making a metal-backed acetabular implant. The method includes roughening a surface of a metallic integument and compression molding a bearing to the surface after the roughening step.
  • The above-noted features and advantages of the present invention, as well as additional features and advantages, will be readily apparent to those skilled in the art upon reference to the following detailed description and the accompanying drawings, which include a disclosure of the best mode of making and using the invention presently contemplated.

  • DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENT(S)
  • Like reference numerals refer to like parts throughout the following description and the accompanying drawings. As used herein, the terms “medial,” “medially,” and the like mean pertaining to the middle, in or toward the middle, and/or nearer to the middle of the body when standing upright. Conversely, the terms “lateral,” “laterally,” and the like are used herein as opposed to medial. For example, the medial side of the knee is the side closest to the other knee and the closest sides of the knees are medially facing, whereas the lateral side of the knee is the outside of the knee and is laterally facing. Further, as used herein the term “superior” means closer to the top of the head and/or farther from the bottom of the feet when standing upright. Conversely, the term “inferior” is used herein as opposed to superior. For example, the heart is superior to the stomach and the superior surface of the tongue rests against the palate, whereas the stomach is inferior to the heart and the palate faces inferiorly toward the tongue. Also, as used herein the terms “anterior,” “anteriorly,” and the like mean nearer the front or facing away from the front of the body when standing upright, as opposed to “posterior,” “posteriorly,” and the like, which mean nearer the back or facing away from the back of the body. Additionally, as used herein the term “generally hemispherical” is intended its broadest sense to encompass all concave and convex geometries suitable for applicable components of prosthetic ball-and-socket type joints such as acetabular and glenoid shells, integuments, bearings, and the like, and, accordingly, includes hemispherical geometries, includes partially spherical geometries that are more than hemispherical, includes partially spherical geometries that are less than hemispherical, and includes all suitable curved polygonal and geodesic geometries as well. Further, as used herein the terminology “taper couple” and inflections thereof mean to fasten together via a taper joint. In general, a taper joint or taper coupling is formed by pressing together (“press-fitting”) a male part (“male taper”) and a female part (“female taper”) having impinging angled or flared surfaces. Taper couplings are generally known in the art. For example, the disclosure of U.S. Pat. No. 6,610,097 to Serbousek et al, which is expressly incorporated herein by reference, discusses manners of making and using various taper couplings that may be suitable for incorporation into applicable embodiments of the present invention.
  • FIG. 1 shows an exemplary hip prosthesis 100 including an exemplary femoral implant 120 and further including an exemplary acetabular implant 140 according to the present invention. Among other things, implant 120 is configured as known to replace natural hip components (not shown) of a distal femur 160. In the exemplary embodiment, implant 120 is metallic and preferably made from titanium. In alternative embodiments, implant 120 may be made from a cobalt chrome alloy or any other suitable biocompatible material(s). Implant 120 includes a post 180. Among other things, post 180 is configured as known to anchor into a medullary canal 200 of distal femur 160. Implant 120 also includes a substantially spherical ball 220. Among other things, implant 140 is configured to replace natural hip components (not shown) of an acetabulum 240. Accordingly, implant 140 defines a generally hemispherical artificial hip socket 260 (see FIG. 2 and FIG. 5) that receives ball 220 as known such that ball 220 has suitable pivotal freedom within socket 260.

Among other things, bearing 406 is configured as known to receive ball 220 (see FIG. 1) in socket 260 and is configured to couple into integument 412 according to the exemplary embodiment of the present invention. In the exemplary embodiment, bearing 406 is made from a plastic, preferably ultra high molecular weight polyethylene (“UHMWPE”).

  • FIG. 6 shows an axial cross-sectional view of integument 412. Among other things, integument 412 is configured to couple around bearing 406 and to couple into shell 300 according to the exemplary embodiment of the present invention. In the exemplary embodiment, integument 412 is metallic and preferably made from titanium.

Axially, taper 1380 extends from taper 1320 by a dimension 1420. Angle 1400 and dimension 1420 are sized such that taper 1380 securely taper couples to taper 980 (of bearing 406; see FIG. 5) upon assembly of sub-assembly 320 (see FIG. 3). Surface 1160 also defines an annular female taper 1440 extending from taper 1380 generally towards rim 1220 at a taper angle 1460 relative to axis 340. Axially, taper 1440 extends from taper 1380 by a dimension 1480. Angle 1460 and dimension 1480 are sized such that taper 1440 securely taper couples to taper 1040 (of bearing 406; see FIG. 5) upon assembly of sub-assembly 320 (see FIG. 3).

  • Integument 412 also includes a generally convex outer surface 1560 that faces generally outwardly away from socket 1170. Surface 1560 includes an annular rim 1620 centered about axis 340 with a radius 1640. Surface 1560 also includes a circular flat 1660 centered about axis 340 with a radius 1680. Flat 1660 is disposed from rim 1620 by an axial dimension 1700. Further, surface 1560 defines an annular male taper 1720 extending from flat 1660 generally towards rim 1620 at a taper angle 1740 relative to axis 340. Axially, taper 1720 extends from flat 1660 by a dimension 1760. Radius 1680, angle 1740 and dimension 1760 are sized such that taper 1720 and flat 1660 have clearance with flat 460 and taper 520 upon assembly of implant 140. Surface 1560 also defines an annular male taper 1780 extending from taper 1720 generally towards rim 1620 at a taper angle 1800 relative to axis 340. Axially, taper 1780 extends from taper 1720 by a dimension 1820. Angle 1800 and dimension 1820 are sized such that taper 1780 has clearance with taper 580 upon assembly of implant 140. Surface 1560 also defines an annular male taper 1840 extending from taper 1780 generally towards rim 1620 at a taper angle 1860 relative to axis 340. Axially, taper 1840 extends from taper 1780 by a dimension 1880. Angle 1860 and dimension 1880 are sized such that taper 1840 securely taper couples to taper 640 (of shell 300; see FIG. 4) upon assembly of implant 140 (see FIG. 3). In the exemplary embodiment, dimension 1700 is less than dimension 500 (of shell 300; see FIG. 4), radius 1680 is less than radius 1640, angle 1800 is less than angle 1740, and angle 1860 is less than angle 1800, while dimension 1820 is greater than dimension 1760, and dimension 1880 is greater than dimension 1820.
  • To begin assembly of implant 140, bearing 406 is press-fitted axially into socket 1170 (of integument 412) to assemble or unite sub-assembly 320. Here, it is noted that although implant 140 is fully exploded in FIG. 3 for clarity of exposition, bearing 406 is preferably pre-operatively press-fitted into socket 1170 by a manufacturer to unite sub-assembly 320 separately from shell 300. Such pre-operative unification of sub-assembly 320 may include temporarily cooling bearing 406 (by immersing it in liquid nitrogen or by any other suitable refrigeration method(s)) immediately prior to press-fitting it into socket 1170, followed by allowing bearing 406 to warm or reheat to a normal temperature (and thus un-shrink or re-expand) within socket 1170 so as to additionally tighten bearing 406 within socket 1170. Upon unification of sub-assembly 320, taper 1040 taper couples to taper 1440, which taper couples surface 760 to surface 1160, and, thus, taper couples bearing 406 to integument 412. It is noted that the strength of the taper coupling reduces or eliminates needs for additional undesirably complex and/or costly structures that might otherwise be required to prevent dislocation and/or rotation of bearing 406 within integument 412.
  • Assembly of implant 140 is completed by suitably rotationally aligning sub-assembly 320 relative to shell 300 about axis 340 and then press-fitting sub-assembly 320 axially into socket 380 (of shell 300). Here, it is noted that the annular designs of taper 1720, taper 520, taper 1780, taper 580, taper 1840, and taper 640 allow for infinite rotational orientation or alignment of sub-assembly 320 (including bearing 406 and, thus, socket 260 as well) prior to press-fitting sub-assembly 320 into socket 380. Such infinite rotational resolution may be especially advantageous for alternative embodiments of the present invention in which socket 260 is off-centered from axis 340. Upon press-fitting sub-assembly 320 into socket 380, taper 1840 taper couples to taper 640, which taper couples surface 1560 to surface 360, and, thus, taper couples integument 412 (and thus, sub-assembly 320) to shell 300. It is noted that the strength of the taper coupling reduces or eliminates needs for additional undesirably complex and/or costly structures that might otherwise be required to prevent dislocation and/or rotation of sub-assembly 320 within shell 300.
  • To assemble prosthesis 100, distal femur 160 and acetabulum 240 are suitably resected, post 180 is suitably anchored into medullary canal 200, and shell 300 is suitably anchored into acetabulum 240. Sub-assembly 320 is rotationally aligned relative to shell 300 and then press-fitted into socket 380. Lastly, ball 220 is inserted into socket 260.
  • In operation of prosthesis 100, bearing 406 stays taper coupled to integument 412 within socket 1170; sub-assembly 320 (including bearing 406 and integument 412) stays taper coupled to shell 300 within socket 380; and pivotal freedom of ball 220 within socket 260 allows articulation of implant 120 relative to implant 140.
  • FIG. 7 shows an exploded axial cross-sectional view of an exemplary alternative acetabular implant 2000 according to the present invention. Implant 2000 is made and used in a like manner to implant 140 (discussed above) except that sub-assembly 320 is replaced with an alternative dome-like or cup-like metal-backed bearing sub-assembly 2020. Sub-assembly 2020 includes an alternative dome-like or cup like bearing 2100 and an alternative dome-like or cup-like backing or integument 2120. Bearing 2100 is made and used in a like manner to bearing 406 except that rim 820 is replaced with a radially inwardly extending annular ledge 2200. Integument 2120 is made and used in a similar manner to integument 412 except that rim 1220 is replaced with a radially inwardly extending annular flange 2300. When sub-assembly 2020 is united, flange 2300 abuts ledge 2200 to additionally inhibit dislocation and/or rotation of bearing 2100 within integument 2120.
  • FIG. 8 shows an exploded axial cross-sectional view of another exemplary alternative acetabular implant 3000 according to the present invention. Implant 3000 is made and used in a like manner to implant 140 (discussed above) except that sub-assembly 320 is replaced with an alternative dome-like or cup-like metal-backed bearing sub-assembly 3020. Sub-assembly 3020 includes an alternative dome-like or cup like bearing 3100 and an alternative dome-like or cup-like backing or integument 3120. Bearing 3100 and integument 3120 are made and used in similar manners to bearing 406 and integument 412, respectively, except that bearing 3100 and integument 3120 are not taper coupled to each other; instead, surface 1160 is replaced with a generally hemispherical generally concave surface 3160, and bearing 3100 is compression molded directly onto surface 3160. Further, prior to compression molding bearing 3100 onto surface 3160, surface 3160 is preferably roughened to produce a more adherent substrate. The roughening is preferably accomplished by dry blasting surface 3160 with 60 grit alumina, or, in alternative embodiments, via any other suitable method.
  • The foregoing description of the invention is illustrative only, and is not intended to limit the scope of the invention to the precise terms set forth. Further, although the invention has been described in detail with reference to certain illustrative embodiments, variations and modifications exist within the scope and spirit of the invention as described and defined in the following claims.
