Description

SAW GUIDE AND FITTING GUIDE FOR WORKING ON A BONE, SUCH AS A FIBULA, FOR A MANDIBULAR PROSTHESIS
The invention relates primarily to a prosthesis saw guide for cutting a bone, such as a fibula intended for the reconstruction of a mandible.
Mandible reconstructions may be necessary for vari- ous reasons. Most often such reconstructions are required because of an impaired lower jaw resulting from a carcinoma. Known is a reconstruction method in which a reconstruction plate is used serving as orientation guide and serving also for the final fixation of the transplant to be grafted. A drawbac of this method is that the reconstruction of the jaw is imperfect, especially because of unsuccessful positioning of the symphysis, the central portion of the lower jaw. The known method has the additional drawback that it is difficult to obtain a good bone-bone contact between the reconstruction elements for the lower jaw. Fixing dental prostheses later on poses a further problem.
The object of the invention is to minimise these problems and to provide, a facility with which it is possible to produce accurately mating joint faces for mandible recon- struction. The invention also provided certain advantages that will be explained in the following.
According to the invention a prosthesis saw guide for cutting a bone such as a fibula for a mandible reconstruction is proposed, which is provided with at least two, and preferably at least three adjoining and pivotingly coupled segments having a first position, wherein the segments form an approximation of a symphysis and at least one of the corpus parts of the mandible connecting at opposite sides of the symphysis, and a second position wherein the segments are placed substantially in each other' s extended direction concurrent with the orientation of the bone.
Such a prosthesis saw guide allows accurate cutting of the fibula so as to obtain tightly mating joint faces of the bone elements from which the reconstructed mandible is formed.
When using three segments, it is possible to reconstruct the symphysis and the two corpus parts placed at oppo- site sides of the symphysis. When using two segments, it is possible to reconstruct the symphysis and one adjacent corpus part of the mandible.
In order to obtain bone elements having tightly mating joint faces, it is advantageous for the segments to be provided at or near their ends with saw guide plates, wherein such saw guide plates of adjacent segments that are placed in their first position can be placed so as to abut against each other, and in this position can be fixed in relation to their respective segments such that when the segments are moved to their second position, the saw guide plates will remain fixed in relation to their respective segments, and that each pair of adjacent saw guide plates of adjoining segments will form an angle in the second position, which is indicative of a bone fragment to be taken from the bone. It is generally pre- ferred for the bone to be used to come from the fibula.
In order to make the best possible reconstruction of the line of the original jaw, it is desirable for each of the segments separately to have an adjustable spacing between the saw guide plates on or near to the ends of the segments. The prosthesis saw guide discussed above is especially suitable for reconstructing the symphysis and the corpus parts of the mandible adjoining the symphysis. If a total mandible reconstruction is required, it is desirable for the three adjoining and pivotingly coupled segments for the sym- physis and the two corpus parts to be supplemented with a fourth and fifth segment, which in the first position of the segments may form an approximation for the ramus parts of the mandible adjoining the corpus parts, and in the second position can be placed substantially in the extended direction of the first three segments, in accordance with the line of the bone .
The invention offers the important advantage that it allows the bone (the fibula) to be cut such that the sites from which the bone fragments are taken, are in the most favourable position with regard to the vascular stem, the sep- tocutane perforators and the dental implants possibly to be lodged in the bone . One thing and another may be conveniently realised by the presence on the segments of fixation members for the bone.
For this purpose, the fixation members are preferably embodied as pylons having a feed-through facility for wire known as Kirchner-wire with which the bone can be fixed in relation to the prosthesis guide.
Conveniently, the fixation members (the pylons) are designed to be adjustable with respect to their position on the guide, in order to be able to optimise the fastening of the bone.
It is further convenient for the pylon on the segment corresponding with the symphysis to be removable. This may facilitate cooperation with the prosthesis fitting guide to be discussed below. As will be clear from the foregoing, an important advantage of the invention is that a bone cut with the use of this prosthesis saw guide provides a number of bone segments that require no further' finishing of angles or bone lengths for a good mandible reconstruction. In another aspect of the invention, the same is also embodied in a prosthesis fitting guide intended and designed for co-operation with the just described prosthesis saw guide. This prosthesis fitting guide is provided with abutting segments, each of which is adjustable in length, and wherein adjacent segments are mutually coupled by means of an adjustable angle fixation member. Since the earlier described saw guide plates of the prosthesis saw guide may be absent from the prosthesis fitting guide, the same may be entirely embodied so as to optimise the fit of the jaw to be recon- structed. To this end the prosthesis fitting guide may be suitably adjusted with reference to, for example, the model of the jaw fragment to be replaced, or with reference to measurements obtained by, for example, a CT-scan or MRI . The prosthesis fitting guide is preferably designed such that each angle fixation member has a hinge that can be coupled with the pivoting coupling of the segments of the prosthesis saw guide. This allows the settings of the pros- thesis fitting guide to be simply transferred to the prosthesis saw guide used for cutting the bone.
The invention will now be further elucidated with reference to the drawing of a non-limiting exemplary embodiment . The drawing shows in:
- Fig. 1 the prosthesis saw guide according to the invention in the second position;
- Fig. 2 the prosthesis fitting guide according to the invention; - Fig. 3 the prosthesis fitting guide in combination with the prosthesis saw guide;
- Fig. 4 the prosthesis saw guide according to the invention in the second position with a fibula placed thereon; - Fig. 5 the prosthesis saw guide according to the invention in the first position with segments of a cut fibula.
Identical reference numbers in the figures refer to similar parts. In the explanation reference is made to the fibula as the bone to be shaped.
With reference first to Fig. 1, the prosthesis saw guide 1 according to the invention is shown, which serves for cutting the fibula intended for a mandible reconstruction. This prosthesis saw guide 1 has a number of abutting and piv- otingly coupled segments.
The segment carrying reference number 3 relates to the symphysis of the mandible. The segments carrying reference numbers 2 and 4 relate to the corpus parts of the mandible. Furthermore, reference number 5 refers to one of the two segments corresponding with the ramus parts of the mandible. Fig. 1 shows the prosthesis saw guide 1 with the segments 2, 3, 4 and 5 placed in a first position, wherein said segments form an approximation of the line of the mandi- ble, in particular of the earlier mentioned symphysis and the corpus parts abutting to opposite sides of the symphysis and, in the case shown, of one ramus part of the mandible.
Fig. 1 further shows that at or near their ends, the segments 2, 3, 4 and 5 are provided with saw guide plates 6, 7, 8, 9, 10, 11, 12 and 13. In the illustrated first position of the segments 2, 3, 4 and 5 these saw guide plates 6-13 may, for so far adjacent saw guide plates are concerned, be placed so as to abut to each other. In the case shown, this concerns, for example, the saw guide plate 7 of segment 2 abutting to the saw guide plate 8 of segment 3 and saw guide plate 9 of segment 3 abutting to saw guide plate 10 of segment 4, and saw guide plate 11 of segment 4 abutting to saw guide plate 12 of segment 5. In this shown first position of the segments 2, 3, 4 and 5 the said saw guide plates can be fixed.
Referring now to Fig. 4, the segments 2, 3 and 4 relating to the symphysis and the corpus parts of the mandible abutting the opposite sides of the symphysis are shown in their second position, wherein the segments are substantially placed in each other's extended direction in correspondence with the line of the fibula 14 that is used for the reconstruction of the mandible. Incidentally, it should be noted that in the second position referred to just now, these seg- ments may have a slightly curved line in order to match the actual line of the fibula to be used. To this end the segments may form an angle exceeding 180°.
Fig. 4 clearly shows that in the illustrated second position of the segments 2, 3 and 4, the saw guide plates re- main in a fixed position with regard to their respective segments. For example, the saw guide plate 10 belonging to segment 4 and saw guide 9 belonging to segment 3, can be seen to form an angle which is indicative of a bone fragment 15 to be taken from the fibula 14 between said saw guide plates 9 and 10. The same applies for the saw guide plate 8, belonging to segment 3 and the saw guide plate 7 belonging to segment 2, forming an angle indicative of the bone fragment 16 to be taken from fibula 14. After completing the cutting operation shown in Fig. 4, the prosthesis saw guide 1 may be returned to the first position shown in Fig. 1. This is shown in Fig. 5, with segments of the fibula 14 positioned thereon and cut in accor- dance with the position of the saw guide plates.
Referring again to Fig. 1, it is shown that each of the segments 2, 3, 4 and 5 is provided with a facility for adjusting the distance of the saw guide plates positioned at or near the ends of the segments 2, 3, 4 and 5. To this end segment 3 is, for example, embodied in two parts with parts 3' and 3'', which by adjusting their mutual distance, also determine the distance between the saw guide plates 8 and 9. In this way it is possible to adequately take into consideration, for example, the vascular course in the fibula to be cut, so as to avoid undesirable damage.
The distance of the saw guide plates 6 and 7 from segment 2 can be adjusted by embodying the segment portions 2' and 2'' so as to be mutually adjustable. Segment 4 shows a comparable facility, with mutually adjustable segment por- tions 4' and 4' ' .
Referring again to Fig. 4, it is shown that the segments 2, 3 and 4 are provided with fixation members 17, 18, 19, 20 and 21 for the fibula 14. These fixation members are embodied as pylons, each of which is provided with a feed- through facility (an opening) for Kirchner-wire 22, known in itself, which can be sunk into the fibula 14. Such pylons may be designed such that they can be repositioned or removed, as required.
Fig. 2 shows an embodiment of a prosthesis fitting guide 23 according to the invention, which is designed to be used together with the above explained prosthesis saw guide. The prosthesis fitting guide 23 is provided with adjoining segments 24, 25, 26, each of which is adjustable in length and wherein adjacent segments 24, 25 and 25, 26 are intercon- nected by means of an adjustable angle fixation member 27, 28.
Each angle fixation member 27, 28 has a hinge pin 29, 30, which as shown in Fig. 3, can be coupled with the pivoting coupling of the segments 2 and 3, and 3 and 4, respectively, of the prosthesis saw guide 1.
It is expressly pointed out that the above-given elucidation is to be understood as non-limiting. This elucidation merely serves to clarify, where necessary, the appended claims without limiting the protective scope of said claims. The protective scope merited by the invention is limited by the appended claims only.
