Definitions
- the present invention relates to apparatus for use in orthopaedic surgery and more particularly to apparatus for use in preparing bones for the fitting of artificial joints. It has become well known to replace worn or damaged human joints by artificial joints and one such joint is the knee. Successful total knee arthroplasty is directly dependent on re-establishment of normal lower extremity alignment, proper orientation of the artificial joint and secure fixation. Instruments and techniques to assist the surgeon in achieving the above factors already exist but are currently made of metal so that they can be sterilised by autoclaving after use. When preparing for total knee arthroplasty, it is necessary to resection both the tibia and the femur. Separate instruments are utilised for resectioning these two bones.
- the present invention provides a kit of parts for use in resectioning an end of a bone during orthopaedic surgery comprising an alignment jig and a cutting jig, the alignment jig including means for positioning pins at a preselected location on the bone to be resectioned, and the cutting jig being a block of molded material having apertures for receiving the positioning pins, further apertures for receiving means for fixing the cutting jig to the bone, and at least one slot for receiving a cutting tool for resectioning the end of the bone.
- Fig 1 shows an alignment jig according to the present invention
- Fig 2 shows a perspective view of a cutting jig for use with the present invention
- Fig 3 shows a tool for use in resectioning the patella
- Fig 4 shows a further tool for use in resectioning the patella.
- the alignment jig consists principally of a main member generally indicated by the reference numeral 1 which comprises a first portion la which telescopically receives a second portion lb so as to enable the length of the main member 1 to be altered to suit the size of the tibia to be resectioned.
- a leg engaging member in the form of a clip 4 which is arranged to hold in position the bottom of the main portion la of the jig near the patient's ankle.
- An adjustment means in the form of a grub screw arrangement 5 operating on a stem 6 projecting from the clip 4 permits the main portion la to be moved forwards and away from the clip so as to ensure that the main portion la lies parallel to the tibia.
- the telescopic portion lb of the main member is provided with a stylus 10 that extends transverse to the axis of the portion 2 and is arranged to contact the end of the tibia to be resectioned.
- the stylus 10 is elongate and the ends are provided with two different sized projections 10a, 10b depending in whether the surgeon wishes to resection based on the highest point of the end of the femur or the lowest point on the femur.
- the stylus 10 is rotatably mounted in the end of the portion lb.
- the portion lb is also provided with a location plate 12 having two through holes 12a which enable two holes to be drilled in the tibia to permit two threaded, headless pins to be accurately placed in the tibia for the reception and accurate location of the tibial cutting jig.
- the plate 12 is shown as being positioned to one side of the portion lb which means that the headless locating ins will be off axis. This is because the cutting jigs are either left or right handed to cause the resectioning cut to be at the correct angle.
- the alignment jig is formed with a separate, adjustable spacer plate 14 so as to ensure that the jig will be set at the correct distance from the tibia. It is rendered adjustable in view of the fact that it is moveable in a slot 15 in the portion lb which permits the correct placement of the plate 14 against the tibia but still permits the overall length adjustment to be achieved. It is to be noted that relative rotation between the two sections la and lb of the main member 1 is prevented. In this case this is achieved by utilising rectangular sectioned members but could be achieved in any other convenient fashion as desired. In operation, the alignment jig is manipulated in much the same manner as is the conventional alignment tool.
- a tibial cutting jig 20 which comprises a mounting portion 21 and a head portion 22 formed with a slot 23 which forms a guide for a cutting saw.
- the cutting jig is either a left or right handed jig but is always medially biased.
- the jig is made of a single piece of moulded construction and if not made of metal may be made of plastic in which case the slot should be lined with a metal insert.
- the mounting portion of the cutting jig 20 is provided with a pair of holes 24 so that the cutting jig can be mounted on the headless locating pins that have previously been inserted into the tibia.
- One or more further pairs of holes such as those indicated by the reference numeral 25 can be provided to allow for repositioning of the height of the jig.
- the jig is in position on the locating pins, it is fixed in position by driving two fixing pins into the tibia through the fixing holes 27. Once securely located on the tibia, cutting can be commenced and it will be noted that the lateral end of the slot is open to allow for optimum saw blade movement.
- the knee joint also includes the patella and although it can be replaced, more often than not it is simply resurfaced.
- a problem when carrying out resurfacing of the patella is that it is difficult to grip and maintain in a fixed position so as to be able to locate a drill guide onto it.
- a kit of instruments for operating on the patella comprises a gripper and a drill jig.
- the patella gripper comprises a tool arranged so as to provide a continual compressive force on the periphery of the patella and is provided with handles to enable the surgeon to hold or manipulate the patella at will.
- the arrangement shown in the drawing is such that the tool is made of two plastics parts 30,31 which are hinged together at one end 32.
- Each of the parts 30,31 adjacent the end 32 is either formed with or faced with metal.
- An interior surface 34 of each metal part is arcuately formed and provided with serrations while the upper and lower metal surfaces 35 are arranged to form a saw guide.
- the two parts 30,31 are provided with an interlocking arrangement such as that shown by the ratchet 36.
- the gripper is opened to a degree sufficient to allow the patella to be received between the serrated surfaces 34 and then the parts 30 and 31 are squeezed together until the patella is securely gripped.
- the parts 30,31 are then held in this position due to the ratchet 36.
- the plastic parts 30,31 can be arranged so that the handles will deform if too much pressure is applied to the patella.
- the patella can be adjusted within the jaws 34 so as to expose a desired amount of bone for resectioning.
- a reciprocating saw is then used to resection the specified portion of the patella utilising the surfaces 35 of the clamp as a saw guide. Once the surface has been resectioned.
- a drill jig such as that shown in Fig 4 is used.
- the drill jig comprises a main body portion 40 provided with a jig locating portion
- patella jig portion 42 which is made of metal and provided with sharp projections 43.
- the patella is arranged to be received between the jig portion 42 and a clamping member 43. Once the patella is securely held in position on the sharp projections 43, by a clamping member 45, holes can be drilled through guide holes 44 and
