Definitions

  • the endoprosthesis of the proximal portion of the femur is formed by a head passing into a neck, then into an intertrochantric section and ending in a shaft inserted into the femoral medullary canal.
  • the intertrochanteric section of the prosthesis is similar in shape to the inner canal of thefen oral intertrochanteric region and is boii rided in its proximal portion by two planes, with one roughly perpendicular to the intertrochanteric axis and the other roughly perpendicular to the femoral neck axis.
  • the present invention relates to artificial joints employed in intra-articular prosthetic replacement, and more particularly to an artificial hip-joint for arthroplasty. It is designed as a means of regaining mobility in the hip-joint after such mobility has been lost due to such diseases an ankylosing spondylitis, arthritis deformans, arthritis infectiosa and aceptic necrosis of the femoral head, as well as femoral neck fractures in the aged.
  • the known artificial hip-joint is installed in the following manner: I
  • the upper end of the femur is exposed by a lateral incision.
  • the trochanter major is cut off and drawn up together with the muscles attached thereto.
  • the femur is cut off at the level of the lower end of the trochanter minor. Then the femoral head together with the neck is removed and the femoral medullary canal and the depressions in the acetabulum are prepared for arthroplasty.
  • the shaft of the endoprosthesis is immersed in the femur.
  • the endoprosthesis ofthe acetabulum is impacted in the prepared actabulum.
  • the trochanter major is impacted to the outer surface of the upper end of the femur. Finally the wound is tightly sutured in layers.
  • the prosthetic replacement employing the known artifical hip-joint provides for the removal of the intertrochanteric region with the result that the affected limb loses in length, and the bearing pad is disposed on the cortical layer of the transverse section in the upper third of the femoral diaphysis.
  • the trochanter major is attached to the prosthesis on the outer surface of the femur, rather than at its normal site.
  • the endoprosthesis is not totally secure from swivelling.
  • One more object of the invention is to provide a method for the installation of, the aforementioned artificial hip-joint. 7
  • an artificial hip-joint comprising an endoprosthesis of the acetabulum connected by a hinged joint with an endoprosthesis of the proximal portion of the femur formed by a head passing into a neck passing into an intertrochanteric section and ending in a shaft, of which the intertrochanteric section has a shape similar to that of the inner canal of the femoral intertrochanteric region and is bounded by two planes, with one roughly perpendicular to the intertrochanteric axis of the femur and the other roughly perpendicular to the axis of the femoral neck.
  • the bearing pad of such artificial hip-joint should serve as an extension of the plane roughly perpendicular to the axis of the femoral neck.
  • An orifice for the fixation of the: lock of the trochanter major should be preferably provided in the plane roughly perpendicular to the intertrochanteric axis.
  • a method for the installation of said artificial hip-joint comprises exposing and cutting off the trochanter major, cutting off the femoral neck at the base thereof at right angles to the axis thereof and removing said neck together with the femoral head, reaming the medullary canal of the femur to a specified size; milling the acetabulum to the specified size, inserting part of the endoprosthesis of the proximal portion of the femur comprising the shaft and the intertrochanteric section into the prepared medullary canal along the axis thereof, inserting part of the endoprosthesis of the acetabulum into the prepared depression of the acetabulum, and finally impacting the trochanter major to the intertrochanteric section of the endoprosthesis of the proximal portion of the femur.
  • the artificial hip-joint of this invention does not call for the removal of the intertrochanteric region to be installed.
  • the trochanter major is immobilized at its normal site; the function of the affected limb is not disturbed, what with all the muscles attached at their normal points; the cavity in which blood can accumulate is substantially reduced; the limb dloes not lose in length and the need to wear orthopaedic shoes is obviated.
  • the endoprosthesis is secure against swivelling in the hip; in case of failure, arthrodesis is feasible, as well as any other subsequent plastic surgery.
  • the present artificial hip-joint provides for the impaction of the endoprosthesis to the femur and pelvis without recourse to cementing agents.
  • FIG. 1 is a view partly in elevation and partly in crosssection of an artificial hip-joint in accordance with the invention
  • FIG. 2 is a sectional view taken along line II-II of FIG. 1, the view looking in the direction of the arrows.
  • FIG. 1 shows an artificial hip-joint, comprising an endoprosthesis l of the acetabulum connected by a hinge with an endoprosthesis 2 of the proximal portion of the femur.
  • the endoprosthesis 1 of the acetabulum is formed as a seat, of which the exterior surface is defined by tiered blades 3 with sharp edges and orifices 4 formed therein for the advancement of burgeoning bony tissue therethrough.
  • the interior surface of the endoprosthesis l of the acetabulum has an irregular through hole to receive two split bushings 5 enveloping more than half of a head 6 of the endoprosthesis 2 of the proximal portion of the femur, thereby forming a hinged joint for the endoprostheses 1 and 2.
  • the endoprosthesis-2 of the proximal portion of the femur comprises a neck 7 on which the head 6 is securely fitted.
  • the neck 7 directly passes into an intertrochanteric section 8 which in turn passes into a conical shaft 9 with fenestras 10 through which burgeoning bony tissue can advance, with the shaft 9 having a shape similar to that of the femoral medullary canal (not shown).
  • the intertrochanteric section 8 is similar in shape to the inner canal of the femoral intertrochanteric region and is bounded in its proximal part by two planes 1] and 12, with the plane 11 perpendicular (or roughly perpendicular) to an intertrochanteric axis 13 and the plane 12 perpendicular (or roughly perpendicular) to an axis 14 of the neck 7.
  • the endoprosthesis 2 of the proximal portion of the femur also has a bearing pad 19 which is an extension of the plane 12.
  • FIG. 2 which is a section of FIG. 1 taken in the plane IIII shows the bearing pad 19 in plan comprising openings or orifices 21 provided to help regeneration processes.
  • lugs 22 are provided to strengthen the endoprosthesis 2 at the point of passage of the neck 7 into the intertrochanteric section 8.
  • the artificial hip-joint is made of titanium, while the hinged joint, the head 6 (FIG. 1) and the bushing S, of an alloy comprising cobalt, chromium and molybdenum.
  • the proposed artificial hip-joint may be manufactured by several methods, for example precision casting, pressing or machining.
  • the method of installing the proposed artificial hipjoint is as follows:
  • the trochanter major is exposed by a lateral incision, cut off at the base thereof at right angles to the intertrochanteric axis and together with the muscles attached thereto drawn up, thereby exposing the joint.
  • the femoral neck is sawed off at the base at right angles to the axis thereof and the head and neck of the patients femur are removed.
  • the medullary canal of the femur is reamed to a required size and shape conforming to the size and shape of the proximal part of the endoprosthesis 2 (FIG. 1), and the patients acetabulum is prepared by milling.
  • the shaft 9 of the endoprosthesis 2 is inserted into the medullary canal of the femur strictly along the axis thereof until the endoprosthesis 2 has been firmly immobilized in the prepared inner femoral canal, with the bearing pad 19 abutted against the femoral plane formed after the neck has been sawn off.
  • the endoprosthesis 2 is secure against turning about the longitudinal axis thereof.
  • the endoprosthesis l of the acetabulum is installed with the help of special guides, and the diameter of the endoprosthesis l is slightly larger than the prepared depression in the acetabulum.
