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. Unfortunately, autoclaving does not necessarily result in the instruments being automatically suitable for reuse and there exists a need for a single-use alternative to the current instruments.
- the jig is in the form of a single unitary block which provides guides for all the necessary cuts to one of the bones.
- two jigs may be provided. In this case, the first jig provides for an initial cut while the second jig provides for all the remaining cuts.
- Fig 1 shows a perspective view of an assembled kit of parts for a disposable cutting jig
- Fig 2 is a diagrammatic cross-sectional view of the jig shown in Fig 1 in position on a femur
- Fig 3 is a perspective view of a part of the kit used to locate guide pins in position
- Fig 4 shows a perspective view of a modification to the embodiment shown in Fig 1
- Fig 5 shows a perspective view of one part of a two part jig embodiment
- Fig 6 shows a perspective view of the other part of the two part cutting jig.
- the embodiments of the present invention are all made of plastics mouldings and are designed to be supplied as a kit of parts in a sterile pack. Once the surgeon has finished, the kit of parts is disposed with. All the embodiments are designed to explain how the femur is prepared ready to accept an artificial knee joint. It is, of course, necessary to also prepare the tibia but it will be appreciated that a similar procedure will be followed to that which will be described later and also appropriate jigs will be provided which will again be made of plastic mouldings so that they may be disposed of after use. In preparing for total knee arthroplasty, it is already known that there is a "5 in 1" procedure as well as a "4 in 1" procedure.
- the apparatus of the present invention consists of a kit of parts formed by an alignment rod 10 made of metal, a detachable handle (not shown) for attachment to one end of the alignment rod, a rotation guide member, an alignment block 11 arranged to be fitted on to the alignment rod and a cutting jig assembly 12 provided with a stylus 13.
- the cutting jig assembly 12 is made from a suitable material which can be moulded into a rigid form. Most, if not all the parts may be made from a plastics material but some or parts of some of the kit may be metal. All are disposable.
- the cutting jig assembly 12 comprises a main body member 20 which is generally box shaped with a top surface 20a, end surfaces 20b and a sloping front surface 20c at the bottom of which is located the stylus 13.
- the bottom of the main body member is recessed in order to receive the end of the bone, in this case the femur, which is to be cut to shape.
- the top surface 20a is provided with an opening 21 (see Fig 2), the upper portion of which is generally V-shaped and which extends into the recess in the main member 20.
- This opening 21 receives a generally V-shaped member 22 which is held in position on the top surface 20a so as to form two angled slots 24 and 25 of a width to permit a tool such as a reciprocating saw to project through the slots for cutting a bone in the recess of the main member.
- the top surface 20a is also provided with a slot 26 which extends normal to the top surface 20a and is again of a width to receive a tool for cutting a bone with recess of the main member.
- the sloping front surface 20c is also provided with an opening 27 which forms two walls 27a and 27b at right angles to each other as is best seen in Fig 2.
- a generally V-shaped member 28 is received in the opening 27 and is held in position on the front surface 20c so as to form two slots 29 and 30 at right angles to each other which extend in the recess in the main member.
- the slots 29 and 30 are each of a width to receive a tool for cutting a base in the recess.
- the slots 24, 25, 26, 29 and 30 are the guides for the five cuts which need to be made to the end of the femur so as to prepare it to receive an artificial knee joint.
- the main member may be provided with a further slot parallel to slot 29. that can be used as a re-cut if required.
- the end surfaces 20b are provided with a number of holes 31 to permit locating pins or screws to be used to fix the assembly 12 in position on the femur.
- the surgeon prepares the femur in basically the same manner as before. Initially, a hole is drilled in the centre of the femur making sure that the hole is parallel to the shaft of the femur in both the anteroposterior and lateral projections. The femur is then sized in order to determine the desired alignment block 1 1 for use with the particular patient, for this purpose a femoral sizing and rotation guide 31 is used to position 2 off headless pints. The guide 31 is removed leaving the headless pins which are then used to set the rotation angle of the subsequent alignment block. A basic design of a rotation guide is shown in Fig 3.
- Alignment blocks 11 each comprise a base member 11 a adapted to contact the top of the femur and an alignment member consisting of a column 1 lb through which the alignment rod 10 is arranged to pass.
- the column 1 lb can be at any one of a fixed number of different angles with respect to the base member 11a and the most common angles are 5 ° , 6 ° and 7 ° .
- the base member 1 la is provided with two slots or holes l ie arranged to receive the two headless pins left in the bone after use of the guide 31 , as best seen in Fig 4. After selection of the appropriate alignment block 11, the cutting jig assembly 12 is then slipped over the alignment rod and also over the columnar part l ib of the locator block 11.
- the stylus 13 on the cutting jig assembly is brought into engagement with the femur and locating screws are inserted into holes 31 on either end surface 20b of the cutting jig assembly 12 in order to fix the cutting jig assembly 12 in place on the femur, at this stage the alignment rod is removed.
- the jig is used by the surgeon in order to determine the precise position of each of the five cuts which are required in order to prepare the femur to accept the artificial joint.
- the cuts are made in the normal order as indicated by the broken lines 1 to 5 shown in Fig 2. After use, all the parts are disposed of. Turning now to Fig 4, this also shows a 5 in 1 cutting jig assembly and the same reference numerals are used for the same parts.
- the jig assembly 12 is inserted onto the alignment block 11 by being slid onto the alignment block 11 in a direction normal to the axis of the alignment rod 10 rather than being slipped axially over the alignment rod 10 and alignment block 11.
- This is achieved by means of a slot 33 in the main body 20 of the assembly 12 and a corresponding slot 34 in the N- shaped member 22.
- the slots 25 and 26 are each constituted by two aligned portions separated by the slots in the recess 20 and 22.
- Figs 5 and 6 show the parts necessary for a 4 in 1 procedure.
- the kit instead of having a single cutting jig assembly as was the case in the previous embodiments, is provided with two cutting jigs.
- the first cutting jig provides for the cutting of the distal femur using a separate cutting guide to that for cutting the remaining cuts for preparing the femur.
- the alignment rod, sizing and provision of the appropriate alignment block occurs as in the embodiments described above.
- a cutting block 40 for a single cut is slipped over the columnar portion of the alignment block 11 as in the embodiment described with reference to Fig 4 and the block 40 is fixed in position by means of screws or pins being inserted through appropriate holes 41 in the cutting block so as to engage the femur.
- the distal cut can then be made utilising a slot 42 as a guide. Slot 42 may be replicated by another slot, 3mm offset but parallel. This is only used should a re-cut be necessary. Holes 1 lc are used to receive 2 off headless pins.
- the block 40 is removed and a 4 in 1 cutting block 44 as shown in Fig 6 is attached. Cutting block 44 is positioned on the headless pins using the slots 45 shown (Fig 6).
- Cutting block 44 provides a jig for cuts 1 to 4 as indicated in Fig 2. As with the previous embodiments, the cutting jigs are made of any suitable disposable material.
