Abstract

A cement delivery apparatus (1) is provided with a cannulated member (6) attached to a cement restrictor (8) for insertion in a bone cavity (4) of a bone (2) into which a prosthetic component is to be cemented. The cement restrictor (8) holds the cannulated member (6) centrally within the bone cavity (4). A tamp (12) has a central axial opening enabling it to be disposed over the cannulated member (6). The cannulated member (6) has at least one opening (10) in its distal end (16) for insertion of cement into the distal end (18) of the bone cavity (4).

Description

CEMENT DELIVERY APPARATUS The present invention relates to a cement delivery apparatus, particularly for cement delivery to a bone cavity before implantation of a prosthetic component.
More particularly, the cement delivery apparatus can be used in hip revision surgery using the impaction grafting technique.
Currently, the known art of impaction bone grafting requires a"bone mantle"to be built up through the use of a tamp forming the bone allograft into the desired shape for the implant. The tamp is often cannulated such that it can be guided by a central guide wire within the cavity. Once the void has been built up, the tamp and the guide wire are removed and cement is injected into the void prior to implantation of a prosthetic component such as a hip stem. In this known method, there is a high probability of the cement gun nozzle disturbing the "bone mantle"as it is used to retrograde fill the void.
According to the present invention, there is provided a cement delivery apparatus comprising a cannulated member for insertion in a bone cavity, the cannulated member having at least one aperture in the wall of the cannulated member at a distal end of the cannulated member.
The apparatus may also include a means for holding the cannulated member centrally in the cavity.
Preferably, the cement delivery apparatus includes a tamp having a central opening in which the cannulated member can be disposed.
Preferably, the cannulated member is in the form of a cannulated rod or tube.
Preferably, the means for holding the cannulated member centrally within the bone cavity is in the form of a member extending transversely from the cannulated member across the bone cavity.
Preferably, the cement delivery apparatus includes a cement gun for insertion of cement into the canal of the cannulated member.
Preferably, the cannulated member is detachable from the means for holding the cannulated member centrally within the bone cavity.
An embodiment of a cement delivery apparatus in accordance with the present invention is now described, by means of example only, with reference to the accompanying drawings in which: Figure 1 is a cross-section of the cement delivery apparatus in accordance with the present invention in situ in a bone cavity, before injection of cement; Figure 2 is a detail of a distal portion of the cement delivery apparatus of Figure 1; and Figure 3 is a detail of the cement delivery apparatus of Figure 1 during insertion of the cement.
Referring to the drawings, a cement delivery apparatus 1 is provided for insertion of cement into a bone cavity 4 in a bone 2. In particular, the cement delivery apparatus 1 can be used for cement delivery in hip revision surgery using the impaction grafting technique. In the case of hip provision surgery, the bone 2 is a patient's femur which is to be prepared for insertion of a prosthetic hip stem.
The cement delivery apparatus 1 has a cannulated rod 6 which is held centrally in the bone cavity 4 by a cement restrictor 8 which extends radially from a distal end 16 of the cannulated rod 6 across the bone cavity 4. The cement restrictor 8 defines the distal end 18 of the bone cavity 4 into which cement is to be inserted.
The cannulated rod 6 has at least one opening 10 in the wall of the rod 6 and may have a plurality of small holes. The at least one opening 10 is at the distal end 16 of the rod 6 adjacent the cement restrictor 8.
The cannulated rod 6 is disposed within a tamp 12 in a central axial opening 24 in the tamp 12.
The proximal end 26 of the cannulated rod 6 can be attached to a cement gun noie.
The present invention combines the use of a central guide wire with a cement delivery system. The guide wire is replace by the cannulated rod 6. The cannulated rod 6 is detachably connected to the cement restrictor 8.
In use, the cement restrictor 8 attached to the cannulated rod 6 is placed in the bone cavity 4, A tamp 12 is placed in the bone cavity 4 and is guided centrally within the bone cavity 4 by insertion of the cannulated rod 6 within a central axial opening 24 of the tamp 12. The tamp 12 impacts bone allograft 20 into the desired shape for the implant. The cavity 4 is then ready for injection of the cement 22 and a cement gun is attached to the proximal end 26 of the cannulated rod 6. Cement 22 is injected into the cannulated rod 6.
The cement 22 travels down the cannulated rod 6 to the distal end 16 of the rod 6 and exits from the rod 6 through the at least one hole 10 in the distal end 16 of the rod 6.
The pressure of the cement 22 entering the bone cavity 4 at the distal end 18 of the bone cavity 4 forces the tamp 12 up the cannulated rod 6 towards the proximal end 26 of the rod 6. The provision of the tamp 12 in the bone cavity 4 during insertion of the cement 22 helps the cement 22 to be pressurised. Once the tamp 12 is forced clear of the bone cavity 4, the cement gun can be removed from the cannulated rod 6, the tamp 12 removed and the cannulated rod 6 detached from the cement restrictor 8 and removed from the bone cavity 4. The bone cavity 4 is then ready for implantation of the prosthetic component.
The cement delivery apparatus 1 has the advantage of the"bone mantle"being protected during the removal of the tamp 12 from the bone cavity 4 as the tamp 12 is removed in a controlled fashion along the cannulated rod 6 by the pressure of the cement 22 distal to the tamp 12. The"bone mantle"is protected from the cement gun insertion as the cement 22 is inserted through the cannulated rod 6.
As the tamp 12 effectively caps the cement column, the pressure in the cement 22 can be controlled as it is being injected.
As the bone cavity 4 is filled with cement 22 from the distal end 18 of the bone cavity 4, any loose bone particles are forced out of the bone cavity 4. Loose bone particles can weaken a cement mantle.
Improvements and modifications can be made to the foregoing without departing from the scope of the present invention.
