Definitions
- the present invention relates to a total trochitero-acromial prosthesis of the shoulder, that is to say a prosthesis intended to treat mechanical and rheumatic attacks of the shoulder, known in particular under the term of ruptures of the cuff, or periarthritis humeral scapulo.
- the present invention aims to restore this freedom of movement of the shoulder and to remove the pain due to the abovementioned attacks, it being understood that the mechanical joint of the shoulder, that is to say the humero-glenoid joint does not is not affected.
- a prosthesis comprising two elements, namely: a trochiterian element having the shape of a spherical sector provided with means for fixing to the location of the trochiter beforehand sectioned, and an acromio-coracoid element having substantially the shape of a cylindrical or spherical segment intended to constitute an artificial articular vault by fixing, by one of its ends, to the coracoid process, and by its other end on the underside of the acromion, so as to cover the aforementioned trochite element, its axis passing through the center of the humero-glenoid joint.
- the prosthesis in a certain number of cases, and in particular in the event of total absence or inefficiency of the peri-articular or capsular muscles which, normally, provoke an active movement of descent of the humeral head in the case of abduction or elevation of the arm, the prosthesis, and consequently the bone tissues which carry it, can be subjected to very high stresses which can be harmful in the long run.
- the present invention proposes to solve this problem in the case where the pulley effect of the elevating muscle heads of the deltoid muscle is insufficient to cause, taking into account the aforementioned efforts, a suitable lowering of the humeral head during the contraction of the deltoid muscle.
- the prosthesis according to the invention comprises two elements, namely: a trochiterian element, for example of the type described in patent FR-A-2 418 644, having the shape of a spherical convex sector whose diameter is preferably equal to or less than that of the humeral head, and provided with fixing means at the location of the trochiter, and an acromial element having a bearing surface for the trochiterian element and provided with fixing means on the underside of the acromion, so as to cover the aforementioned trochite element, and the dimensions of which are such that it remains free to move, without overflowing onto the collarbone, in one piece with the acromion, once that -this was cut off at the level of the pillar of the thorn of the scapula.
- a trochiterian element for example of the type described in patent FR-A-2 418 644, having the shape of a spherical convex sector whose
- the assembly formed by the acromion and the acromial prosthesis element forms a true patellar element which, at the deltoid contraction, presses powerfully on the humeral head to lower it.
- This pulley effect is all the more important as the raising of the arm begins. It is canceled when the collarbone, acromion and humerus are in the same horizontal plane at the end of the elevation.
- the bearing surface of the acromial element may advantageously be concave, the radius of concavity, preferably spherical, possibly being greater than or substantially equal to the radius of the convex spherical sector of the trochite element, with the aim of reducing or to remove transverse displacements of the two elements with respect to each other.
- the dimension of the acromial element can be such that it occupies substantially the entire length of the acromion released by resection at the level of the pillar of the spine of the scapula.
- the acromial prosthesis element does not extend beyond the underside of the part of the acromion which has been released. from the spine of the scapula, by sectioning at the level of the pillar.
- the subject of the invention is also a method of fitting this prosthesis, characterized in that it comprises, in addition to the step of fitting the trochite element in a manner already known, the sectioning of the acromion at the level of the pillar of the thorn of the scapula and the fixing of the acromial prosthesis element under the acromion, either before or after sectioning, the acromion, with its acromial prosthesis element, then remaining free relative to the spine of the scapula to play a role of patellar articulation.
- the trochite element can, as in the case of French patent FR-A-2 418 644, be offset laterally relative to the center of the humeral head.
- the trochite element can advantageously be constituted by a spherical segment, preferably metallic, comprising one or more anchoring pins capable of being fixed by cement or in any other manner known per se, in holes made in the part trochottir Jardin of the humeral head, shaped by section or machining, as described in the aforementioned French patent.
- the trochiterian element consists of a solid spherical segment, provided with an anchoring pin capable of being fixed, by cement or in any other manner known per se, in a well formed in the sectioned trochitium of the head of the humerus.
- the trochite element can be made of high density polyethylene or any other similar material.
- the trochite element has the shape of a spherical cap, the edge of which has several fixing lugs intended to be anchored and fixed by cement or by any other appropriate means, in wells arranged to receive them in the section trochottir Jardin section of the head of 1 humerus.
- the trochite element can be made either of high density polyethylene, or of metal such as stainless steel of quality tolerated by the human body, polished or covered with a high density ceramic such as, for example, chromium oxides or any other material having a high hardness and capable of being polished and lapped in order to perfect the sliding.
- the internal face of the trochite element can advantageously be covered with asperities or a ceramic with open porosity in order to perfect the bond on the sealing cement used, such as methyl methacryiate.
- the acromial element consists of a part, preferably made of high density polyethylene, and preferably covering all of the underside of the acromion. Its articular surface is spherical concave and substantially the same diameter as the convex spherical trochite part.
- the connecting face of this acromial element is arranged to match the underside of the acromion, slightly concave, and present fixing means, such as pins or studs which can be firmly fixed in holes made on the underside acromion.
- the acromial element can also be made of a metal having sufficient mechanical strength to play its role of patellar arch for the trochite element. This acromial element is then advantageously made of polished stainless steel of tolerated quality. by the human body.
- the trochite element is made of polyethylene or a metal coated with high density ceramic; but it is obvious that, conversely, one could possibly provide a trochite element having the form of a spherical cap in polished stainless steel, at least the underside of the acromial element being coated with a high ceramic density.
- the surface of the acromial element intended to come into contact with the lower face of the acromion can be treated so as to have a degree of roughness facilitating bone recovery, or else covered with various means facilitating this recovery, such as for example a layer of hydroxyapatite or an open porosity ceramic, for example alumina.
- hydroxyapatite is often desired to supplement the mechanical fixing means, whatever they may be, the operative effects of which are immediate.
- the hydroxyapatite projected onto a surface intended to be in contact with a bony face provides secondary fixation within a few months following the surgical operation; this fixation which becomes complementary to the mechanical fixation is of a physico-chemical nature and is obtained by adsorption of the bone constituents on 1 "hydroxyapa ⁇ tite; generally it is calcium hydroxyapatite.
- FIG. 1 is a schematic front sectional view of a shoulder in a normal state
- FIG. 2 is a front sectional view of a shoulder carrying the prosthesis at the start of the arm elevation
- FIG. 3 is a front sectional view of a shoulder carrying the prosthesis, at the end of elevation movement;
- - Figure 4 is a perspective view of the trochite prosthesis element;
- FIG. 5 is a perspective view of the acromial prosthesis element.
- the acromion 5 is also fixed to the clavicle 9 by the acromioclavicular ligaments 10 and the trapezium clevis 11 is common to the acromion and the clavicle.
- FIG 2 we see a shoulder provided with a prosthesis according to the invention.
- the acromion 5 was separated by sectioning its pillar 6 and the supraspinatus 7 disappeared due to the disease.
- the acromial prosthesis element 12 has a concave spherical articular surface 12a and, as can be seen in the drawing, does not extend beyond the clavicle, and therefore does not interfere with the coracoid process. It is held fixed in the acromion and on the lower face thereof, by studs entering wells made by the surgeon in the acromion, in which is sealed with standard surgical cement.
- the trochiter has been eliminated and replaced by the trochiterian prosthesis element 13 in the form of a spherical cap having substantially the same radius as that of the concave cap 12a.
- the thickness of the acromial element 12 is preferably of the order of 8 to 10 mm, so as to compensate for the sub-acromial void left by the disappearance of the supraspinatus. The thickness is increased to increase the power of the movement.
- the adjustment of the muscular tension of the muscles of the humeral cap can be obtained by the choice of the thickness of the acromial prosthesis or by the choice of the position or the length of the trochite element along the humeral shaft.
- the upper face 12b of the acromial element 12 can be provided with lugs or pins 12c intended to penetrate into recesses dug into the acromion and be cemented there.
- the above upper face 12b, as well as the pins 12c is treated, either by surface treatment, or by covering a layer of a suitable material, in order to facilitate its bone integration.
