Description
"Osteosynthesis plate for femur fractures" DESCRIPTION
Technical field
The present invention relates to an osteosynthesis plate for femur fractures.
More particularly the present invention relates to an osteosynthesis plate for fractures in the epiphysis or head of the femur.
Prior art
Osteosynthesis plates for treating fractures in long bones, such as femur, are known in the art.
Such plates generally have an elongated shape and they are available in several models, depending on the shape and size of the bone to which they have to be applied.
In the International Patent Application WO 97/08999, for instance, a plate for fixing fractures in the head of a bone is disclosed. Said plate comprises an elongated portion that can be fixed to the bone by means of a plurality of screws and an end portion that is provided with a barrel suitable for being inserted into the bone for housing a supporting means for the bone head, for instance a head screw or, alternatively, a head nail or similar device.
According to prior art, in order to make the head screw or the head nail correctly penetrate into the bone head, the axis of the barrel through which said screw or said nail passes is arranged on a plane that is perpendicular to the plane where the plate lies and it is inclined at a certain angle with respect to said plane where the plate lies, said angle depending on the shape and the size of the fractured bone. In the osteosynthesis plates available in the market, said angle is usually comprised between 90° and 150°.
In case of femur fractures, however, said solution is not sufficient for guaranteeing a correct insertion of the bone head screw or nail inside the femur head.
In fact, the plates according to prior art having this kind of structure do not take into account the femur antiversion angle.
In general, the femur axis is not perfectly straight, but it is curved laterally and forwardly, so that the femur neck and head are in an advanced position with respect to the rest of the femur. More precisely, the femur antiversion angle can be defined as the angle formed by the femur neck and head with the frontal plane of the individual; in other words, once a femur is placed on an horizontal plane, the femur antiversion angle can be defined as the angle formed by the femur neck and head with said horizontal plane. In children, the femur antiversion angle can reach 30° - 35°, while in adult people, in the absence of specific pathologies, is usually comprised between 10° and 15°.
Due to the femur antiversion, in the osteosynthesis plates of known type it is not possible to guarantee a correct positioning of the bone head screw or nail inside the femur head. The main object of the present invention is to provide an osteosynthesis plate for femur fractures capable of overcoming the above drawbacks of prior art and of guaranteeing a correct insertion and a correct positioning of the bone head supporting means associated to the osteosynthesis plate inside the femur head, said bone head supporting means comprising in particular a bone head screw or a bone head nail.
This and other objects are achieved by the osteosynthesis plate as claimed in the appended claims.
Disclosure of the invention
Thanks to the fact that the axis of the bone supporting means does not lie on the plane passing through the longitudinal axis of the body of the osteosynthesis plate and perpendicular to the plane where said body lies, but it is adequately inclined with respect to said plane, the femur antiversion angle is duly taken into account and the correct positioning of the bone head supporting means inside the femur head is guaranteed. Advantageously, according to the invention, the axis of the bone head supporting means is inclined at an angle comprised between 1° and 30°, and preferably comprised between 1° and 15°, with respect to the plane passing through the longitudinal axis of the osteosynthesis plate.
According to a first preferred embodiment 'of the invention, the inclination of the bone head supporting means is obtained by making in the body plate through-holes that are inclined at an adequate angle with respect to the plane passing through the longitudinal axis of the body of the osteosynthesis plate and perpendicular to the plane where said body lies and by inserting into said through-holes barrels suitable for guiding the bone head supporting means into the femur head.
According to a second preferred embodiment of the invention, a distal portion and a proximal portion are identified in the plate body, said distal portion being intended to be placed along the diaphysis of the fractured femur and said proximal portion being intended to be placed at the head of said femur, and the plane where the proximal portion of the plate lies is rotated at an adequate angle around the longitudinal axis of the plate itself with respect to the plane where the distal portion of said plate lies. According to an alternative version of said second preferred embodiment of the invention, the rotating angle between the plane where the proximal portion of the plate according to the invention lies and the plane where the distal portion of said plate lies is not fixed, but it can be adjusted, so that it can fit femurs with different antiversion angles. Brief Description of the Drawings

- Figure 2 is a top view of the osteosynthesis plate of Figure 1 ;
- Figure 3 is a top view of an alternative version of the osteosynthesis plate of Figure 1; - Figure 4 is a side view of an osteosynthesis plate according to a second preferred embodiment of the invention;
- Figure 5 is a front perspective view of the osteosynthesis plate of Figure 4.
Detailed Description of Some Preferred Embodiments of the Invention With reference to Figure 1 and 2, the osteosynthesis plate 1 for femur fractures according to the invention comprises a body having a thin and elongated shape and suitable for being placed on the diaphysis of a fractured femur. Said body comprises a plurality of through-holes 3 for the passage of screws (not shown) for blocking the body itself against the femur diaphysis.
The osteosynthesis plate 1 further comprises bone head supporting means provided at the end of the body of said plate that during use is closer to the femur head and suitable for penetrating into said head.
More particularly, in the illustrated embodiment said supporting means comprises a bone head screw 9. A barrel 7 is provided for guiding the bone head screw inside the femur head. In the illustrated embodiment the barrel 7 is separated from the body 1 and it can be rigidly fastened thereto. To this aim, the body of the osteosynthesis plate 1 comprises an internally threaded through-hole 5 and, correspondingly, the barrel 7 comprises a threaded end portion 7a, suitable for engaging with the internal thread of said through- hole 5, so that the barrel 7 can be rigidly fastened to the body 1 simply by screwing. According to known art, the axis A of the bone head screw 9 - and therefore of the barrel 7 and of the through-hole 5 - forms an angle α with the plane P wherein the body of the osteosynthesis plate 1 lies, said angle α being comprised between 90° and 150° depending on the shape and size of the fractured bone (and being equal to about 120° in the example shown in Figure 1).
Moreover, according to the invention, the axis A of the bone head screw 9 - and therefore of the barrel 7 and of the through-hole 5 - forms a non- null angle β with a plane P' passing through the longitudinal axis of the body of the osteosynthesis plate 1 and perpendicular to the plane P wherein said body lies.
More particularly, said angle β is chosen each time so as to take into account the antiversion angle of the patient's femur, whereby it is guaranteed that the bone head screw 9 correctly penetrates into the head
of the fractured femur.
Said angle β will be therefore preferably included in the range 1° - 30°, and more preferably included in the range 1° - 15°.
Always referring to Figures 1 and 2, the osteosynthesis plate 1 further comprises an additional screw 15, having an anti-rotation function, preferably associated to a corresponding barrel 13 for being guided into the head of the fractured femur.
In the illustrated embodiment, the barrel 13 of the additional screw 15 is also separated from the body 1 and it can be rigidly fastened thereto. To this aim, the body 1 comprises an internally threaded through-hole 11 and, correspondingly, the barrel 13 comprises a threaded end portion 13a, suitable for engaging the internal thread of said through-hole 11, so that the barrel 13 can be rigidly fastened to the body 1 simply by screwing. Advantageously, the axis of the additional screw 15 - and therefore of the barrel 13 and of the through-hole 11 - is parallel to the axis A of the bone head screw 9 and therefore it forms the same non-null angle β with the plane P' passing through the longitudinal axis of the body 1 and perpendicular to the plane P wherein said body 1 lies. In Figure 3, an alternative version of the embodiment of the invention shown in Figure 1 and 2 is illustrated, said alternative version differing from what is described above for the kind of the bone head supporting means only. In this alternative version, in fact, said supporting means comprise a bone head nail 9'. According to the above description with reference to the first embodiment of the invention, the bone head nail 9' can be coupled to the body of the osteosynthesis plate V by means of the provision of a sleeve or barrel 7', that is separated from the body of the osteosynthesis plate V and can be rigidly fastened thereto. Also in this alternative version, the axis A' of the bone head nail 9' forms an angle α' with the plane P wherein the body of the osteosynthesis plate I' lies, said angle α' being comprised between 90° and 150° depending on the shape and size of the fractured bone, and said axis A' forms a non-
null angle β' with the plane P' passing through the longitudinal axis of the body of the osteosynthesis plate 1' and perpendicular to said plane P wherein said body lies.
More particularly, said angle β' is chosen each time so as to take into account the antiversion angle of the patient's femur, whereby it is guaranteed that the bone head nail 9' correctly penetrates into the head of the fractured femur, and said angle β' will be therefore preferably included in the range 1° - 30°, and more preferably included in the range 1° - 15°. With reference now to Figures 4 and 5, according to a second preferred embodiment of the invention the osteosynthesis plate 101 comprises a body, having a thin and elongated shape and comprising a distal portion 101a, suitable to be placed on the diaphysis of a fractured femur and provided to this aim with a plurality of through-holes 103 for the passage of screws (not shown) for blocking the body of the osteosynthesis plate 101 against the femur diaphysis, and a proximal portion 101b, provided for being placed at the head of said femur and equipped to this aim with a barrel 107 provided with a longitudinal central channel 105 for guiding bone head supporting means into the femur head. The barrel 107 is separated from the body of the osteosynthesis plate 101 and it can be rigidly fastened thereto. To this aim, the proximal portion 101b of the body of the osteosynthesis plate 101 comprises an internally threaded through-hole and, correspondingly, the barrel 107 comprises a threaded end portion, suitable for engaging the internal thread of said through-hole, so that the barrel 107 can be rigidly fastened to the body of the osteosynthesis plate 101 simply by screwing.
As seen in Figure 5, according to the invention, the distal portion 101a and the proximal portion 101b of the osteosynthesis plate 101 do not lie on the same plane. On the contrary, the plane where the proximal portion 101b of the body of said plate 101 lies is rotated at a non-null angle γ around the longitudinal axis L of said body with respect to the plane where the distal portion 101a of said body lies. As a consequence, the longitudinal axis S of the channel 105 of the barrel
107 correspondingly forms a non-null angle γ with the plane passing through the longitudinal axis L of the body of the osteosynthesis plate 101 and perpendicular to the plane where the distal portion 101a of said body lies. More particularly, said angle γ is chosen so as to duly take into account the antiversion angle of the patient's femur, whereby it is guaranteed that the bone head supporting means inserted through the channel 105 of the barrel 107 correctly penetrate into the head of the fractured femur. Said bone head supporting means can consist, for instance, in a bone head screw or in a bone head nail.
The angle γ is preferably included in the range 1° - 30°, and more preferably included in the range 1° - 15°.
According to the preferred embodiment illustrated in Figures 4 and 5, the body of the osteosynthesis plate 101 is made as a single piece and the angle γ between the plane where the proximal portion 101b of said body lies and the plane of the distal portion 101a of said body lies is fixed. In an alternative version of said preferred embodiment of the invention, it is possible to manufacture the proximal portion 101b and the distal portion 101a of the body of the osteosynthesis plate 101 as separate pieces that can be rigidly fastened to each other.
According to this alternative version, it is advantageously possible to adjust the angle γ between the plane where the proximal portion 101b of said body lies and the plane of the distal portion 101a of said body lies is fixed by rotating the two portions of said body with respect to each other and successively fixing them when the desired angle has been obtained. In this way, an osteosynthesis plate capable of being adjusted for perfectly fitting femurs with different antiversion angles can be obtained. It is evident from the above description that the osteosynthesis plate according to the invention achieves the object set forth above, since it allows to guarantee a correct insertion of the bone head supporting means into the femur head, thanks to the fact that the antiversion angle of the patient's femur is duly taken into account. It is also evident that the preferred embodiments described in detail above
are exclusively given by way of non limiting examples and that several modifications and variants are possible without departing from the scope of the invention as defined by the appended claims.
For example, even if an osteosynthesis plate provided with a barrel for the insertion of the bone head supporting means into the femur head has been described, it also possible to apply the invention to an osteosynthesis plate wherein the bone head supporting means are directly fastened to the plate body, without the interposition of a barrel.
