Definitions
- the present invention relates to a method and an ap- paratus for working bone cement placed in a cavity of a bone, for instance in the medullary canal of the femur, for fixing a prosthesis in the cavity.
- Bone cement is prepared by mixing two or more components with each other to form a soft curing mass. The soft mass is placed in the cavity for receiv ⁇ ing the prosthesis and, after curing, fixing it in the cavity.
- the bone cement currently used is of the poly- methyl methacrylate type (PMMA) which is prepared by mix ⁇ ing a powder of polymers with a liquid of monomers. The resulting mixture is caused to cure by polymerisation.
- PMMA poly- methyl methacrylate type
- the penetration of the bone cement into the spongy bone depends on how carefully the cavity, for instance a medullary canal, has been cleaned with respect to devita- lised tissue.
- the degree of penetration also depends on the viscosity of the cement and the pressure of applica ⁇ tion. The lower the viscosity of the cement is and the higher the pressure of application is, the more easily does the penetration take place. With decreasing viscosity and increasing pressure, the PMMA mass however emits a larger amount of highly volatile monomers which have been found to be cytotoxic, that is have an injurious effect on vital cells, and may therefore cause tissue injuries.
- the monomers may then interfere locally with the flow of blood and also give rise to intravascular hemolysis and inflam ⁇ matory reactions leading to ischemia, necrosis and re- sorption of bone substance.
- monomers have been found to produce not only localised injuries but also system injuries, for instance by affecting the heart and by causing fat embolism in the lungs.
- Tissue injuries may also arise in other ways.
- the major portion of the bone marrow is removed, which causes injuries to blood vessels and, hence, adversely affects the flow of blood with a consequent risk of ischemia and tissue death.
- Polymerisation of the PMMA cement takes place with emission of heat, the local temperature in ⁇ crease being proportional to the amount of cement used. Excessive temperature may in itself cause tissue injuries and also, the emission of injurious monomers increases with increasing temperature.
- the object of the present invention is to provide a method making it possible to bring about efficient and durable immobilisation of a prosthesis in a cavity by means of bone cement, while overcoming as far as possible the above-mentioned drawbacks by ensuring a thorough and uniformly distributed penetration of bone cement into the spongy bone with a minimum of injuries to bone tissue and blood vessels and a minimum of air bubbles in the bone ce ⁇ ment.
- this object is achieved by a method for working bone cement placed in a cavity of a bone, for instance in the medullary canal of the femur, for fixing a prosthesis in the cavity, which method is characterised in that the bone cement placed in the cavity is vibrated mechanically.
- Another object of the present invention is to provide a device for carrying out this method.
- this object is achieved by means of a device for working bone cement placed in a cavity of a bone, for instance in the medullary canal of the femur, for fixing a prosthesis in the cavity, which device is characterised by vibrating means adapted to vi- brate the bone cement placed in the cavity.
- the vibrating means suitably is adapted to execute a rotary movement.
- the device has pressure loading means having a cross-sectional shape corresponding to that of the cavity, and adapted to be introduced in the cavity to be pressed against the bone cement placed there ⁇ in.
- the device used in the test and schematically illu ⁇ strated in the drawing has a flexible shaft 1 which is connected at one end to a motor (not shown) having a speed of rotation of 16,000 rpm, and which is connected at the other end to a chuck 2 normally used in a dentist's drill ⁇ ing equipment.
- a metal tube 3 is arranged around the chuck 2.
- a steel pin 4 having a diameter of about 2.5 mm is in ⁇ serted in the chuck 2 and axially extends a certain dis- tance outside the metal tube 3.
- the steel pin 4 has a ra ⁇ dial projection 5 at its free end.
- a rubber seal 6 having a central portion and an annular skirt portion is fixed with its central portion to the free end of the metal tube 3 by locking screws 7.
- the rubber seal 6 has a central through bore in which a metal sleeve 8, closed at its free end, is mounted.
- the steel pin 4 extends into the metal sleeve 8 with its radial projection 5 engaging the inner side of the me ⁇ tal sleeve 8 and slightly inclining the metal sleeve.
- the steel pin 4 is shown in a position of ro- tation where the radial projection 5 is directed to the right, thus inclining the metal sleeve 8 to the right.
- the metal sleeve 8 exe ⁇ cutes a movement of rotation, substantially describing a cone.
- the device is shown when introduced in a cavity 9 of a bone 10 which in the contemplated ex ⁇ periment is a necrobone from cattle.
- a bone 10 which in the contemplated ex ⁇ periment is a necrobone from cattle.
- con ⁇ sisting of the distal part of the femur cut horizontally just above the condyles a vertical hole having a depth of about 4 cm and a diameter of about 34 mm has been drilled.
- the interspongy fat has been removed by heating in water.
- a PMMA bone cement mass 11 was placed after the different components had been mixed.
- the test device was thereafter introduced in the cavity 9 by descending the metal sleeve 8 into the mass of bone cement 11 and lightly applying to the mass of bone cement 11 the rubber seal skirt portion which as appears from the drawing has substantially the same diameter as
- the axial pressure was about 0.2 kp/cm .
- the steel pin 4 and, thus, the metal sleeve 8 were rotated for 30 s, thereby vibrating the mass of bone cement 11, where ⁇ upon the device was removed.
- the bone 10 was exa ⁇ mined, and it clearly appeared that the penetration of the mass of bone cement into the spongy bone was deeper and considerably more uniformly distributed than was the case when the same experiment was conducted without vibrating the mass of bone cement.
