Definitions

  • Bone implants such as joints for the hip, elbow and wrist, usually have shanks which are engaged in corresponding passages in the particular bone concerned and are anchored in the passage by means of a quicksetting bone cement such as methylmethacrylate.
  • a quicksetting bone cement such as methylmethacrylate.
  • the invention provides a shank having texturized zones of depressions in an external surface for anchoring a bone implant in a bone.
  • the zones are generally disposed in the load bearing zones of the surface of the shank while the shank narrows in cross-section toward one end.
  • the shank is secured in a bone by a suitable bone cement so that the cement fills the spaces within the texturized zones of depressions.
  • the depth of the depressions in each zone is between and 100 microns (1.1.). Shallower depths lead to unreliable adhesion between the cement and the shank surface, and depths of more than 100 microns (u) readily result in air bubbles remaining when the shank is driven into the bone cement, the bubbles impairing adhesion. Also, the possibility of withdrawing the shank from the bone is impaired in increasing proportion as the depressions are made deeper. The optimum depth is governed very largely by the particular bone cements used, more particularly their viscosity, changes in volume and their ability to make good contact, i.e., the extent to which they can mate accurately with a texture on the shank surface to provide a faithful copy in reverse of the texture.
  • At least the bearing and load-taking surfaces are provided with the texturized zones of depressions.
  • these surfaces are provided with regular toothing extending transversely of the direction in which the implant is introduced into and withdrawn from the bone. In this event, to facilitate withdrawal, the distance between discrete teeth can increase towards the narrow end of the shank.
  • Textures in the form of recesses of a shape resembling shells or troughs have proved satisfactory in other embodiments of the invention. Both kinds of texture can, of course, be used with advantage simultaneously.
  • the load-taking and the bearing surfaces can have toothing while the other surfaces can have shell-like recessings.
  • the texturized shank surface can also be roughened, eg by sand blast-- ing with 0.05 to 0.2 millimeters (mm) diameter silica pellets.
  • the edges and corners at junctions between the various surfaces which make up a multi-surface polygonal shank, and the raised and recessed junctions between the various teeth and between and in the troughs are very rounded and free from projections.
  • FIG. 1 illustrates a sectional view through a femur fitted with a prosthetic head having a shank according to the invention
  • FIG. 2 diagrammatically illustrates a sectional view through an arm fitted with an artificial elbow joint using shanks in accordance with the invention
  • FIG. 3 diagrammatically illustrates a sectional view of a prosthetic wrist joint fitted in a forearm and a carpal bone using shanks according to the invention
  • FIG. 4 illustrates a considerably'enlarged and diagrammatic plan view of atexturized zone of depressions in the form of regularly disposed trough-like recesses
  • FIG. 5 illustrates a vew taken on line VV of FIG.
  • FIG. 6 illustrates a side elevational view of a cutting bit for forming the depressions shown in FIGS. 3 and 4;
  • FIG. 7 illustrates a plan view of the bit of FIG. 6.
  • a prosthetic femur head 1 has been implanted in a femur 2 which has been appropriately prepared by surgery.
  • the head 1 includes a shank 3 anchored by means of a bone cement 4, e.g. methyl methacrylate, in a passage or recess 5 in the femur bone 2 whose relatively compact cortical substance is shown more darkly dotted than the porous spongy substance.
  • the shank 3 has a polygonal large-area shape with rounded comers and edges.
  • the shank cross-sectional shape resembles a kite (FIG.
  • the surface of the shank 3 which is non-porous has a texturized zone which is, indicated in FIG. 1 by trough-like discrete unconnect recesses or depressions between teeth of a regular or uniformly formed toothing.
  • An endeavor is also made to show, in diagrammatic and sketch form, the toothing formed as texturizing on the surfaces 6, 7 which appear just as section lines. Also indicated is an increase in tooth spacing towards the exposed end of shank 3.
  • an elbow joint 8 has a shank 9 on one part which shank 9 narrows on all sides.
  • the shank 9 is introduced into a recess or passage or the like in a humerus 10 and retained by bone cement 4.
  • a shank 11 on the other part of the joint 8 is anchored similarly in an ulna 12.
  • one shank 14 is retained by bone cement 4 in a radius bone 25 and another shank 26 is anchored by bone cement 4 in a carpal bone and/or metacarpal bone 27.
  • the texturizing can take the form e.g. of trough-like or shell-like recesses or depressions 15 disposed regularly in rows a, b, c. If the raised parts between the discrete shells 15 are also removed inside the various rows a, b, c, the resulting toothing is very advantageous for the surfaces 6 and 7.
  • the advantages of toothing are that, in cooperation with a shank shape that narrows on all sides and continuously, a fitted shank can be removed simply by applying a force sufficient just to release the shank by one toothing step in the withdrawal direction. Thereafter, the shank can readily be withdrawn from the cement bed.
  • the shank material 16 is usually one of the known metal alloys which are conventionally used for bone implants.
  • the depth 1 of the depressions in the texturized zones can be between and 100 ;1.
  • From 20 to 30 microns ([1,) has been found a very good value for the depth 1 in existing shanks where methyl methacrylate is used as the bone cement.
  • satisfactory dimensions for a single shell of shell-like texturizing are given by a ratio of length u to width v to depth t of 12 4: l.
  • the surface 17 of the texturized shank 3 has the texturizing roughened as well, to further improve adhesion between the cement 4 and the shank 3. That is, the portions between the depressions which are rounded so that the depressions mergetogether smoothly, can be roughened. As mentioned, this roughness is produced by blasting with silica pellets of from 0.05 to 0.2 millimeters (mm) diameter.
  • a technique which has proved satisfactory for producing the shell-like texturing is the cutting or milling of the periphery of the shank transversely of a longitudinal direction.
  • a suitable tool 20 for this can be seen in FIGS. 6 and 7.
  • the cutting bit has, at the junction between the cylindrical portion and the circular end face, a radius r of curvature which is adapted to the bit diameter d and to the required trough size.
  • the bit has a central plane surface s which is also of aparticular diameter.
  • the bit 20 has six lips 21 a, 21
  • the trough depth t arising from the cutting or milling operation is mainly governed by the cutting radius r.
  • the length u can be controlled to some extent by cutter speed and/or the rate of feed, and the width v can be varied within limits by varying the line spacing of the cutting operation.
  • the same tool 20 can be used to produce toothing, but instead of cutting being performed by the cutting edges of radius r, the cutting is performed by the side walls of the cutting edges.
  • the cutter 20 has the diameter d of 8 millimeters (mm), the radius r of curvature of approximately 3.25 millimeters (mm) and the diameter of the plane surface s of approximately 1.5 millimeters (mm).
  • the feed in this case is 250 mm/min. and cutter speed is approximately 8 meters/minute (m/min).
  • the texturizing can also be formed in the shank surface e.g. by means of forming punches.
  • a solid shank for implanting in a bone cement to anchor a bone implant in a bone said shank having a narrowing cross-sectional area towards one end and an external non-porous surface having discrete unconnected depressions therein between raised portions of said shank, said depressions being between 10 microns and microns depth.
  • a shank as set forth in claim 1 having a longitudinal axis and wherein said surface includes at least two load bearing zones having said depressions therein, each zone having a regular toothing extending transversely of said longitudinal axis to fonn said depressions.
  • a shank as set forth in claim 4 wherein said regular toothing includes transverse rows of spaced apart teeth with the spacing between discrete teeth increasing toward said one end of said shank.
  • a shank as set forth in claim I having a plurality of longitudinal side walls defining a generally trapezoidal cross-sectional area, at least two of said side walls having said depressions therein.
