Description
"Intrαmedullαry nail for the osteosynthesis of trochanteric fractures of the femur" Technical field
The present invention relates to an intramedullary (endomedullary) nail for the promotion of osteosynthesis of bone fractures, and in particular for the surgical treatment of femur's trochanteric fractures. Background
Femur's trochanteric fractures are usually treated with intramedullary nails provided with a tubular element that is longitudinally inserted in the bone marrow, a cephalic screw which is introduced into a corresponding seat obtained in the greater trochanter, in order to guide the osteosynthesis in correspondence of the fracture, and stabilizing screws positioned in the distal portion of the nail, i.e., that nail portion which, upon application of the device, is near to the knee, to allow the blocking of the nail on the femur bone.
An intramedullary nail of this type for the treatment of trochanter fractures has some drawbacks. It has been, in fact, found that with this type of device, the infection risks increase because of the additional incisions necessary for the positioning of the stabilizing screws in the nail distal portion.
Besides, the positioning of such screws, because of the difficult alignment and centering with the special seats obtained on the nail, is very complex and requires a rather long operation time as well as repeated exposures of the patient and the surgeon to x rays to ascertain the correct evolution of the operation.
Still more, these devices require a rather long recovery time for the patient. In fact, in the first post-operation period, the stabilizing screws are coupled in a stable manner, without any clearance, in
special seats obtained on the nail, which is why during this first rehabilitation stage, it is not possible to load the leg and to stimulate the fracture rima. Only in a second period, the type of coupling of the stabilizing screws with the intramedullary nail change, passing from a stable distal blocking to a dynamic distal blocking, following a further operation, and the stimulation of the fracture rima becomes therefore possible.
Object of the present invention is to provide an intramedullary nail for the treatment of femur's trochanteric fractures, such as to allow to solve all the drawbacks of the known art.
Within this scope, an object of the present invention is to provide an intramedullary nail for femur's trochanteric fractures, such as to reduce the risk of infections.
Another object of the present invention is to provide an intramedullary nail such as to reduce the operation and biological recovery times.
Another object of the present invention is to provide an intramedullary nail whose application is easy and allows to reduce the exposure of patient and surgeon to x rays. Description of the invention
These objects are achieved by the present invention that relates to an intramedullary nail for the surgical treatment of femur's trochanteric fractures, comprising a tubular element provided with a cephalic screw and at least a stabilizing element, characterized in that said stabilizing element comprises a couple of wire rods which are angled at one end and arranged longitudinally and internally relatively to the tubular element, to come out from two openings located in the distal portion of said tubular element.
An intrαmedullαry nail of this type needs no additional incisions to. block the stabilizing element to the femur, and reduces, therefore, infection risks.
Besides, for the application of this device, one prevents the difficult operations necessary for the alignment and centering of the stabilizing screws in the special seats obtained in the distal portion of the tubular element, which allows to reduce the operation and x ray exposure times.
According to a preferred embodiment of the present invention, the screw and/or the tubular element have grooves for housing wire rods.
According to an advantageous aspect of the present invention, the grooves extend longitudinally on at least a portion of the internal surface of the tubular element. According to another advantageous aspect of the present invention, the grooves extend on the external surface of the cephalic screw in parallel with its inclination axis.
According to a preferred embodiment of the present invention, the wire rods comprise a pointed and angled end, to block the nail to the femur bone, a central flat portion and at least a portion having a circular section.
A distal blocking of this type is stable and at the same time dynamically controlled, and the micro-movements realized by the wire rods allow an early load on the femur that promotes a rapid biological recovery.
According to a preferred embodiment of the present invention, the intramedullary nail comprises also a device for blocking in their position both the wire rods and the cephalic screw. Brief description of the drawings
Further characteristics and advantages of the present invention will be stressed more clearly thanks to the following description, offered by way of non limiting title, with reference to the attached schematic drawings, wherein: - Figure 1 is a side view of the intramedullary nail according to an embodiment of the present invention;
- Figure 2 is a longitudinal section view of the intramedullary nail of Figure 1 ;
- Figure 3 is still another longitudinal section view of the proximal portion of the intramedullary nail according to the present invention;
- Figure 4 is a cross-section view of the intramedullary nail in correspondence of the cephalic screw according to the present invention.
Best mode for implementing the invention Figure 1 shows a possible embodiment of an intramedullary nail
1 for the surgical treatment of femur's trochanteric fractures, comprising a tubular element 2 provided with a cephalic screw inclined with respect to the axis of the tubular element 2, and at least a stabilizing element composed of at least a couple of wire rods 4, 5 that are angled at an end and positioned longitudinally and internally relatively to the tubular element 2, to come out from two openings 9, 10 obtained in the distal portion of said tubular element.
In the preferred embodiment, shown in Figures 1 and 2, wire rods are in number of two and come out from two openings obtained in the distal portion of the tubular element 2.
In the present description, by "distal portion of nail 1 or tubular element 2" there is intended to indicate that portion of nail 1 or tubular element 2 that, upon the application of device 1 on the femur lies near the knee.
Consequently, in the present description by "proximal portion of nail 1 or tubular element 2" there is intended to indicate that portion of nail 1 or tubular element 2 that, upon the application of device 1 on the femur, lies near the acetabulum of the iliac bone. For the housing of wire rods 4, 5 that extend longitudinally throughout the whole length of nail 1 , the tubular element 2 is provided with special grooves.
According to a preferred embodiment, as shown in Figure 4, the intramedullary nail is provided wit two grooves 6, 7 for housing the wire rods that extend longitudinally for a portion of the tubular element 2 and that are located in a diametrically opposite manner on the internal surface of such element.
Also the cephalic screw 3 is provided with grooves 8 (Fig. 3), suitable to prevent the interference with wire rods 4,5, in correspondence of their intersection with the cephalic screw 3 and also to provide an engaging seat for the blocking device of said screw.
In particular, the cephalic screw 3 is provided, as shown in Figures 2 and 3, with four screws 8 located in a diametrically opposite manner on the external surface thereof, which extend in parallel with its inclination axis (indicated by a broken line in Figures 1 and 2).
Wire rods 4,5 have a first end portion having a circular section that continues, going down towards the distal portion of nail 1 , and a second flat portion in correspondence of the cephalic screw 3, and a third portion, having also a circular section, pointed and angled, that allows an easy coming out from openings 9, 10, obtained in the distal portion of the nail.
In order to facilitate the coming out of the pointed end of wire rods 4, 5, also openings 9, 10, obtained in the distal portion of nail 1 ,
are inclined and show the same inclination of the pointed end of wire rods 4, 5.
Upon the coming out from the special openings 9, 10 and the blocking on the femur, thanks to the engagement of their pointed end with the nearest cortical bone tissue, wire rods 4,5 are blocked in their position by a blocking device located at the end of the proximal portion of the tubular element 2.
In detail, the blocking device has a threaded plug element 1 1 (Fig. 3) that blocks wire rods 4,5 against the internal surface of the tubular element 2. In order to allow a correct engagement of the plug element 1 1 with the tubular element 2, the latter has on its internal surface, in correspondence of its proximal portion, a thread 12 complementary to the one realized on the plug element 1 1.
The plug element 1 1 has also, arranged along its symmetry axis, a threaded coupling seat 17 for a nut 13 and a counter-nut 14, suitable to block in its position, with respect to the rotation, the cephalic screw 3.
The end of nut 13, which extends longitudinally along the vertical axis of the tubular element 2 until it comes in touch with the cephalic screw 3, engages, as shown in Figure 3, in one of the four grooves 8 obtained on the external surface of the cephalic screw 3, blocking it in its position.
Besides, to prevent movements that are likely to jeopardize a correct osteosynthesis of the femur in correspondence of the fracture rima, the cephalic screw 3 has a flaring head 15 or a step-like head, that prevents any translations of the cephalic screw 3 along its inclination axis, and in particular prevents the cephalic screw from further penetrating into the greater trochanter.
On the opposite end of the cephalic screw there is positioned in a known manner a thread 16 that realizes the engagement of the cephalic screw 3 and therefore of the whole nail 1 with the femur bone, and in particular, with the greater trochanter. In the proximal portion of the intramedullary nail 1 , above the cephalic screw 3, an inclined through-hole 20 is positioned that allows, during the application of the intramedullary nail 1 , thanks to a guide screw, not shown and removed afterwards, to fix nail 1 in its position before the insertion of the cephalic screw 3 into the greater trochanter.
