Abstract

A radiographic marker for arthroplasty and especially for hip surgery comprises a radio-opaque element 3, 4 for association with a non-radio-opaque joint member, the element being shaped to define at least two planes, so as to appear on a radiograph and indicate both the rate of wear of the join member and tilting of the joint member. <IMAGE>

Description

SPECIFICATION Improvements relating to hip surgery This invention relates to arthoplasty, and especially to hip surgery and particularly to the use of marking means to appear on X-ray plates relating to a joint replacement.
It is now well known in hip surgery to use a plastics material acetabular cup which is cemented into position in the pelvic bone structure. For example, the cup is made of high density polyethylene which is non-radio-opaque and thus a marker is required to appear on X-ray plates to indicate the thickness of the plastics material and thus the distance between the cup and the femoral head and for indicating the rate of any wear.
The main object of the present invention is to provide a marker for the following two main purposes: (1) To function as a marker capable of assessing the rate of wear of plastics material cup.
(2) To measure the version of the cup indicating whether it is tilted forwardly (anteverted) or backwardly (retroverted).
The ability to assess these parameters on an X-ray plate is essential in the study of position, wear, stability, and any progressive tilting of the acetabular cup. In this way a two-dimensional image of the cup is obtained.
According to the present invention a radiographic marker for arthroplasty, comprises a radio-opaque element for association with a non-radio-opaque joint member, the element being shaped to define at least two planers.
Moreover there is also provided an acetabular prosthesis comprising a non-radio-opaque acetabular cup for receiving a femoral head and a radioopaque marker in accordance with the invention, the marker and cup being fixed relative to each other.
The marker is preferably spring steel wire or strip.
The marker can be held in position by location means. The marker can be located in grooves externally of the cup and its tail ends turned inwardly, to fit in holes in the acetabular cup.
The invention also provides a method of providing a marking on an X-ray photographic plate for use in relation to hip surgery comprising a radio-opaque marker in a fixed position relative to a non-radioopaque acetabular cup, so that the marker defines at least two planes to facilitate correct positioning and observation of the cup with regard to the angle and wear.
The marker is held in a fixed position relative to the joint member and the radio-opaque marker defines two planes which will allow the angular position of the joint to be found out. The relationship between the two planes defined by the marker is different for each angular position of the joint.
Two examples of the invention will now be more particularly described with reference to the accompanying drawings in which: Figure 1 is a front view of an acetabular cup with a wire marker in position; Figure2 is a side view of Figure 1; Figure 3 is a front view of a first example of a marker; Figure 4 is a side view of the marker shown in Figure 3; and, Figure 5 is a front view of a second example of a marker.
In the particular illustrated embodiment of this invention, a marker 1 for association with an aceta bular cup 2 is made of spring steel wire or strip which is shaped to form a bow 3 in the central region of the wire and then the end parts 4 are bent laterally towards each end into a plane at right angles to the plane of the bow and such end parts 4 are curved in their lengths to form two semi-circles of a two-part bow. The ends of said two parts finish in close proximity to one another and the tail end extremities 5 of such end parts are bent inwardly.
A radiographic marking element 1 formed in the above manner is located on the external periphery of an acetabular cup 2 in grooves 6, 7 produced in such peripheral surface. Conveniently the cup is provided with a pair of arched grooves 6 which cross one another at right angles in the surface of the exterior of the cup and these two grooves are linked together by annular grooves 7 of which the largest diameter of groove 7 is close to the gapped perimeter 8 of the cup.
A cup and marker formed in the above manner are associated by the central bow 3 of the marker 1 being inserted into one of the pair of grooves 6 to pass over the summit of the cup and the ends 4 forming the two-part bow of the marker are located in the aforesaid annular groove 7 near the perimeter 8 of the cup. The aforesaid tail ends 5 of the marker can pass into a hole at the junction of the grooves 6, 7 to assist in retaining the marker in position.
In use the marker will show clearly on an X-ray plate and the anterior bow of the marker will run transversely across the path of the X-rays, its movement being further magnified on the X-ray plate. This face ensures that the marker is extremely sensitive to the tilt cup and gives a two dimensional image of the acetabular cup. On the X-ray plate the anteversion of the cup approximates the two bows of the marker and retroversion separates them.
It is further considered that the two bows 3 and 4 being made of a single wire give a better X-ray appearance and addition of a single one, although effective, is less asthetic in appearance. Although the anterior bow may be placed posteriorly to reduce its sensitivity it is considered that this is undesirable and that it cannot be seen during the insertion of the cup.
A second example of a marker is shown in Figure 5. In this case only one of the ends 6 of the central bow 3 is bent round to form the bow at right angles to the central bow 3. In this case there are no inturned ends 5. This is a simpler arrangement than the first example.
