Definitions
- the present invention relates to a trapezian or trapezo-metacarpal implant, comprising a rod terminated by a head.
- the rod is intended to be inserted into the metacarpus of the thumb, and the head to be housed in a space obtained in particular by removing the entire trapezium, in the case of a trapezian implant, or part of the trapezium, in the case of '' a trapezio-metacarpal implant.
- the implant according to the invention can be used to treat rhizarthrosis, a very frequent condition consisting of osteoarthritis of the base of the thumb, essentially trapezo-metacarpal.
- This implant has two main drawbacks:
- silicone causes in some patients an allergy known as siliconite; in addition, due to its too low hardness, the silicone wears out in contact with the neighboring bones, causing deterioration of the implant;
- FIGS. 1A, 1 B and 1 C illustrate a trapezian implant 1, the rod 1 a of which is mounted in the metacarpus 2 and the head 1 b completely replaces the trapezium; in FIG. 1A, the implant is normally positioned relative to the neighboring bones and in particular relative to the scaphoid 3 with which it is in contact; FIG. 1B shows a typical configuration of subluxation of the implant during a force of force involving the thumb and at least one other finger from the hand ; FIG. 1C shows a typical configuration of dislocation of the implant after such force of forceps.
- Trapezo-metacarpal implants are also known, such as the Swanson condylar implant, the head of which is housed in a space obtained on the one hand by making a cut on the proximal end of the metacarpus and on the other hand by removing a part of the trapezoid opposite this proximal end. These implants are also made of silicone.
- a titanium version of the Swanson condylar implant has, however, been proposed.
- the material in which these trapezo-metacarpal implants are made is unsuitable. As explained previously, the silicone is too soft. Titanium is too hard and wears out the bones with which it is in contact. It also makes the implant painful for the patient.
- FIG. 3 represents the condylar implant of Swanson with its rod 5a inserted into the metacarpus 2 of the thumb and its head 5b housed in a deep and narrow cavity of the trapezium 6.
- the small radius of curvature of the part surface area of the head in contact with the trapezoid limits the angular movement of the implant, which restricts the movements of the thumb.
- the present invention aims in particular to provide a trapezian or trapezo-metacarpal implant which is at least as stable as the implants mentioned above and which is relatively easy to put in place.
- a trapezian or trapezo-metacarpal implant comprising a rod terminated by a head, the rod and the head being intended, respectively, to be inserted into the metacarpus of the thumb and to be housed in a space obtained in particular by removing at least part of the trapezium, the surface of the head being constituted by a base connected to the rod and intended to rest on the proximal end of the metacarpus, a part of the distal surface opposite the base and serving as a contact surface with the bone located opposite the proximal end of the metacarpus, and a connecting part connecting the base and the distal surface part of the head, characterized in that the distal surface part of the head is inclined with respect to a longitudinal axis of the rod at a predetermined angle, so that when the rod is mounted straight in the metacarpus , the distal surface part of the head can be located in varus.
- Said bone opposite the proximal end of the metacarpus is the scaphoid in the case
- the stability of the implant is given by the positioning in varus of the distal surface part of the head, as in the aforementioned article by Y. Allieu et al "The trapezian implant of Swanson in the treatment of peri-trapezian osteoarthritis ". However, unlike this article, it is not the entire implant that is positioned in varus, but only part of the implant, including the distal surface part of the head.
- the inclination of the distal surface part of the head with respect to the rod allows the rod to be inserted straight into the metacarpus, that is to say along the longitudinal axis thereof.
- the rod can therefore be placed exclusively in the soft central part of the bone, which facilitates the work of the surgeon who does not have to dig in the hard peripheral part. Such positioning of the rod also avoids weakening the bone to a great extent.
- the head can be wide and its distal surface part can have a large radius of curvature corresponding substantially to the radius of curvature of the trapezo-metacarpal joint.
- the head can also be flatter. The surgeon therefore does not have to make too large a cut on the proximal end of the metacarpus, nor to dig deep into the trapezium, for which the removal of a small cap with a large radius of curvature may suffice.
- the stability of the implant according to the invention can be further increased by designing the latter so that the distal surface portion of the head is not only inclined but also offset relative to the longitudinal axis of the rod on the side of the implant where the angle between the distal surface part of the head and the longitudinal axis of the rod is the smallest.
- At least the distal surface part of the head is designed in pyrocarbon.
- Pyrocarbon has a very good coefficient of friction with the bone, which allows it to slide without adhesion on the bones with which it is in contact and without causing wear.
- silicone which is too soft
- titanium which is too hard
- pyrocarbon has a modulus of elasticity, also called Young's modulus, close to that of bone. The reciprocal forces exerted on the implant and surrounding bones are therefore distributed evenly, thereby reducing the risk of pain for the patient.
- FIG. 1 A, 1 B and 1C already discussed, show a part of a hand in which is implanted a trapezium implant according to the prior art, respectively in the rest position, in the clamp position with subluxed implant and in the position forceps with luxated implant, this part of the hand being seen from the dorsal side, with the thumb and the trapezo-metacarpal joint in profile and the other fingers seen from above;
- FIG. 2 already discussed, shows, in the same type of view as that of Figures 1 A, 1 B and 1 C, a trapezium implant according to the prior art mounted obliquely in the metacarpus of the thumb;
- FIG. 3 already commented, shows, in the same type of view as that of Figures 1 A, 1 B and 1 C, a trapezo-metacarpal implant according to the prior art mounted in the metacarpus of the thumb;
- FIG 4A shows a side view of a trapezo-metacarpal implant according to a first embodiment of the invention;
- FIG. 4B shows a side view of a variant of the implant according to the first embodiment of the invention
- FIG. 5 shows, in the same type of view as those of FIGS. 1A,

- FIG. 6 shows a side view of a trapezo-metacarpal implant according to a second embodiment of the invention
- - Figure 7 shows a side view of a trapezium implant according to a third embodiment of the invention.
- FIG. 8 shows a side view of a trapezium implant according to a fourth embodiment of the invention.
- FIG. 4A represents an implant according to a first embodiment of the invention.
- the implant according to this first embodiment is a trapezo-metacarpal implant, in the general form of a nail, it comprises a rod 10 terminated, at a so-called proximal end, by a head 20 and whose opposite end , called distal, is constituted by a point 101.
- the rod 10 is intended to be inserted into the metacarpus of the thumb, and the head 20 to be housed in a space obtained on the one hand by making a cut, or resection, on the proximal end of the metacarpus and on the other hand by removing part of the trapezium opposite the proximal part of the metacarpus.
- the head 20 has a flattened shape. Its longitudinal section is circular. Its surface is constituted by an annular and flat base 201 connected to the proximal end of the rod 10 and intended to rest on the proximal part of the metacarpus, a distal surface part 202 opposite the base 201 and serving as a contact and friction surface with the remaining part of the trapezoid, and a rounded and annular lateral edge 203 connecting the distal surface part 202 to the base 201.
- the distal surface portion 202 has a convex shape, and preferably consists of a spherical cap.
- the rod 10 comprises a frustoconical part 102 whose end of smaller diameter is connected to the tip 101 and the end of larger diameter is extended by a divergent connection part 103 connecting the base 201 of the head 20 to the part frustoconical 102 of the rod 10.
- the head 20 as a whole is inclined relative to the axis 104 of the rod 10.
- the base 201 is inclined relative to the axis 104 in the same direction as the distal surface portion 202, and the angle a.
- the angle of inclination ⁇ is typically at least equal to 10 ° and preferably equal to 15 °.
- the diameter D of the head 20 and the radius of curvature R of the distal surface portion 202 are chosen large enough to respect as best as possible the anatomical curvature of the trapezo-metacarpal joint.
- the implant according to the invention is designed in four different sizes.
- the ratio between the diameter D of the head, measured along a longitudinal axis of the head inclined with respect to the longitudinal axis 104 of the rod in the same direction as the portion of distal surface 202 and d an angle equal to the angle ⁇ , and the length L of the rod, measured along the longitudinal axis 104 of the rod between the distal end 101 and the point of intersection I between the plane 205 defined by the base 201 and the axis 104, is advantageously at least equal to 0.84.
- the ratio between the radius of curvature R of the distal surface portion 202 and the length L of the rod is advantageously at least equal to 0.6.
- the thickness E of the head can be relatively small. Typically, the ratio between the thickness E of the head 20, measured perpendicular to the base 201, and the length L of the rod is at most equal to 0.42.
- the whole head 20 is offset with respect to the axis 104 on the side C1.
- the geometric center of the head 20, like the center of the distal surface portion 202 is located outside the axis 104, on the side C1.
- the axis of symmetry 206 of the distal surface part 202 intersects the longitudinal axis 104 of the rod 10 at point I of intersection between the plane 205 defined by the base 201 of the head 20 and the axis 104.
- the distal surface part 202 can be further offset with respect to the rod 10.
- the implant according to the invention constituted by the rod 10 and the head 20, or at least the distal surface part 202 of the head 20, is advantageously designed in pyrocarbon.
- the implant is formed from a graphite substrate coated with a layer of pyrocarbon.
- An oblique varus cut is made in the proximal end 2a of the metacarpus 2 and part of the trapezoid 6 located opposite this proximal end 2a is removed, to provide a space suitable for accommodating the head 20. Then a straight hole is formed in the metacarpal bole, along the longitudinal axis 2b thereof. The rod 10 of the implant is then forced into the hole until the inclined base 201 of the head 20 comes to bear on the inclined section 2a of the metacarpus, so that the head 20 comes to lodge in the above space, in varus position.
- the rod 10 of the implant is thus positioned straight in the soft central part of the metacarpus, delimited in FIG. 5 by the dotted lines 2c, and is surrounded by the hard peripheral part of the latter.
- the placement of the implant is therefore no more complicated than for the Swanson trapezian implant illustrated in FIGS. 1A, 1B and 1C.
- the implant is more stable than the Swanson trapezian implant.
- This stability of the implant according to the invention is mainly due to the fact that the surface of the implant in contact with the trapezium is increased by the position in varus of the distal surface part 202.
- FIG. 5 illustrates the balance of forces exerted between the implant according to the invention and the trapezium when the patient makes a force of forceps by firmly holding an object between the thumb and the index finger.
- the implant exerts on the trapezium a force F having a component T1 tangential to the contact surface and a component N1 normal to this contact surface.
- the large contact surface between the trapezium and the head of the implant allows the trapezium to exert in response a reaction force R having a tangential component T2 sufficient to counterbalance the tangential component T1 of the force F.
- This balance of forces maintains the implant in contact with the trapezium and therefore significantly reduces the risk of dislocation.
- Figure 6 shows a second embodiment of the implant according to the invention.
- the implant according to this second embodiment is a trapezo-metacarpal implant which differs from the implant according to the first embodiment essentially in that only the distal surface portion 202a is inclined relative to the rod 10a, and not the entire head 20a.
- the base 201a of the head 20a is perpendicular to the longitudinal axis 104a of the rod 10a.
- the connection part 203a of the head 20a is therefore higher on the side C2 of the implant where the angle between the distal surface part 202a and the axis 104a is greater, than on the opposite side C1.
- the distal surface portion As in the first embodiment, the distal surface portion
- 202a is preferably offset relative to the axis 104a of the rod on the side C1.
- this implant When placed in the patient, this implant rests on a straight cut previously made in the proximal end of the metacarpus, and not on an oblique cut as in the first embodiment.
- FIG. 7 shows a third embodiment of the invention.
- the implant according to this third embodiment is a trapezium implant, that is to say that its head 20b has a shape and a size adapted to replace the entire trapezium.
- the distal surface part 202b of the implant has a concave shape allowing it to cooperate with the distal part of the scaphoid.
- the head 20b including the base 201b, the distal surface part 202b and the connector part 203b, is inclined in a comparable manner to the first embodiment.
- FIG. 8 shows a fourth embodiment of the invention.
- the implant according to this fourth embodiment is a trapezium implant, the head 20c of which has a portion of distal surface 202c inclined with respect to the axis 104c of the rod 10c and a base 201c perpendicular to the axis 104c.
- this implant is intended to rest on a straight cut previously made in the proximal end of the metacarpus.
