- ABSTRACT A surgical device for joining broken bone segments includes a rail member configurated to abut against one segment of the bone and has an aperture therein.
- a holder member has an aperture therein and is configurated to slide along the rail member and has a longitudinal slot through which fixing screws can pass and engage with the rail member for fixingthe members against relative movement with respect to one another.
- An elongated connecting means passes through the apertures of the rail member and of the holder member.
- Each of the apertures define a pivot point in which the elongated member is pivotally mounted and forms an angle with the bone which is a function of the relative positions of the two members.
- One end of the elongated member is anchored to the holder member and another end is fixed to another segment of the bone, the elongated member being arranged to pull the last-mentioned segment towards said holder member while abutting against said rail member.
- the present invention concerns a surgical device, particularly for joininga broken bone, and more especially for joining a bone broken in the region of the neck of the femur head.
- connection element which can subsequently be anchored in the rear bone fragment.
- the bone fragments can then be drawn together by means of a capping sleeve that can be screwed onto a part of the connection element which is allowed to protrude from the bone.
- this kind of connection has proved very suitable.
- connection element must in many cases be driven into the neck of the femur head a a different angle.
- the angular range between the femur and the connection element to be driven into the neck of the femur head, which can be considered for this purpose varies approximately from l to 140".
- there is no contact face available for engagement by the capping sleeve it being understood that such contact face should extend perpendicular to the longitudinal axis of the connection element and should support the capping sleeve during the drawing-together of the bone fragments. The joining of the bone fragments thus becomes very difficult, or even impossible.
- a rail is known, one end of which has the shape of a circular are.
- This rail is fixed to the femur in the manner described above.
- the arc forming one piece with the rail, contains a longitudinal groove, in which a nail that is to be driven into the neck of the femur head can be moved.
- a specific angle of the nail in relation to the femur is obtained.
- the nail is fixed in this position by a support plate which may be placed onto that end of the nail which protrudes from the bone, and which serves as back support for the rail which is to be fastened to the nail by a screw.
- the rail is then immovably clamped between the support plate and the head of the screw.
- the known rail cannot, however, be used in association with a connection element of the type described above, since a support plate cannot be fixed to the end Moreover, the support plate required by the known device, which, due to its large surface, cannot penetrate into the bone and therefore lies upon the bone, prevents a contact between the rail and the femur. Only the rear part of the known rail, and the support plate are in contact with the bone when the known device has been fixed. The femur thus lacks lateral support, which is required to prevent displacement of the bone fragments at the line of fracture in the femur.
- Another object is to provide such an improved device which makes it possible to obtain a rigid connection between the fragments of the femur which are held together by a rail constituting a part of the device.
- connection element After the connection element has been inserted and anchored at an angle to the femur which depends on the position and the course of the fracture line, as a rule at between and M0", the rail and the holder, which can be moved along the rail and fixed at the rail, are together pushed over the protruding end of the connection element.
- the capping sleeve required for joining the bone fragments is then pushed through the apertures in the holder and in the rail and is screwed onto the protruding end of the connection element. Only now is the rail screwed to the femur with the aid of fixing screws.
- the already anchored fixing element is clamped by means of the correspondingly matched apertures in the holder and in the rail, and fixed in this position by tightening the holder to the rail.
- the fragments of the neck of the femur head are now drawn together by means of the capping sleeve.
- the head of the capping sleeve is supported either by a washer or directly by the correspondingly shaped holder.
- connection element may be any expansion belt which permits anchoring by means of expansion (i.e. spreading apart), and which utilizes a capping sleeve or nut by means of which the bone fragments can be drawn together.
- connection element and the rail which is fixed to the femur, provides the condition for rapid healing and for the possibility of immediately subjecting the femur to a load.
- the lateral support by the rail which is in contact with the femur over its entire length, prevents a displacement of the bone fragments at the positions of fracture and thus a wrong growing-together of the femur.
- the construction according to the invention has the further advantage that when a load is applied to the femur, the clamping effect obtained in the connection between the connection element and the rail, is reinforced.
- the aperture in the rail and in the holder may be widened from the contact side with the bone in accordance with the pivoting angle of the connection element.
- This construction makes it possible to select narrower drill hole tolerances for the seating of the connection element in the rail and in the holder. The widening is, however, required only in the longitudinal direction of the drill hole, so that proper lateral support for the connection element remains assured.
- that part of the holder which contains the aperture for taking up the connection element may be bent in such a way that it is positioned approximately perpendicular to the longitudinal axis of the connection element.
- the holder may be attached to the rail by means of one or several fixing screws, which are guided in a longitudinal aperture extending parallel to its lateral edge. In this construction, the holder can be moved along the rail and fixed to the rail in a most simple manner for the purpose of pivoting and clamping the connection element; to avoid subsequent painful pressure spots, the screw heads may be recessed in the longitudinal aperture of the holder.
- suitable means in particular screws, may be arranged at the holder, for clamping the connection element which has been taken up in the aperture of the holder.
- This construction prevents the accidental loosening of the capping sleeve which is necessary for the drawingtogether and holding-together .of the bone fragments.
- FIG. 1 is a partial sectional view of a device according to the invention.
- FIG. 2 shows the construction of the aperture in the rail serving for taking up the connection element.
- the device according to the invention comprises a connection element 2 in form of an expansion anchor, which may be anchored in the neck of the femur head 1, a rail 5 which is fastened to the femur 3 by means of fixing screws 4, and a holder 6 which can be moved along the rail and fixed at the rail.
- the connection element 2 has a capping sleeve 7 or nut which may be screwed onto that end of the connection element 2 that protrudes from the bone, a head 8 of which capping sleeve is supported by a bent section 9 of the holder 6 when the bone fragments are drawn together.
- the rail 5 is provided with an aperture 10 for taking up the connection element 2.
- the aperture is widened (i.e., diverges) in the longitudinal direction of the rail 5 from the contact side with the bone, according to the pivoting range of the connection element 2 (see also FIG. 2).
- the rail 5 further contains apertures 11 for taking up the fixing screws 4, by means of which the rail 5 is fastened to the femur 3.
- An upper section 12 of the rail 5 is contoured to conform to a high degree of the outer surface of the femur 3, so that the contact face for the lateral support of the femur 3 is as large as possible.
- a nail (not shown) is first driven into the femur 3 for forming a hole therein.
- the bone is observed on the screen of an X-ray machine to assure that the desired angle 16 be tween the passage formed by the nail and the rail 15, is obtained.
- the sleeve of element 2 is placed over the protruding rear end of the nail and driven into the bone, so as to slide over and along the nail.
- the nail has no further purpose and is withdrawn.
- the screw which effects expansion of the sleeve is now threaded into the expansion body of the element 2 and turned as required to expand the sleeve of element 2, thereby anchoring the latter in the femur 3.
- the rail 5 is placed over the end portion of element 2 which protrudes outwardly of the bone, and is screwed to the latter by the screws 4.
- Capping sleeve 7 and holder 6 are then pushed onto the projecting portion of element 2 and threaded onto the same until sleeve 7 enters aperture 10.
- the holder 6 is then secured to rail 5 until screws 15 and its bent section 9 then acts as an abutment for the head 8 of sleeve 7, permitting the drawing-together of the bone fragments or sections in response to requisite turning of sleeve 7.
- connection element 2 In order to pivot the connection element 2 in the aperture 1.0 of the rail 5, serving as pivot point, the holder 6 is moved upwards or downwards. In the holder 6 too, the aperture 13, provided for taking up the connection element 2, is widened (i.e., diverged) in accordance with the pivoting range. The movement of the holder 6 is made possible by the position of the longitudinal aperture 14.
- the holder 6 is fixed to the rail 5 by means of fixing screws 15 which are guided in the longitudinal aperture 14.
- the angle 16 between the connection element 2 and the rail 5 varies in dependence on the displacement of the two apertures 10, 13 in the rail 5 and in the holder 6. The angle 16 is selected as required by shifting of the holder 6 relative to rail 5, whereupon the selected angle is then set by fixing the holder 6 on the rail 5 with the aid of the screws 15.
- the capping sleeve 7 is clamped by means of the fixing screws 17 at the bent section 9 0f the holder 6, and thus secured against accidental loosening.
- my device is not limited to cases where a bone fracture has actually occurred. There are instances where my device can be employed to advantage even if no fracture exists. For instance, it is well known that the bones of older persons are much more susceptible to fracturing than those of younger persons. In such circumstances my device could be used as a preventive, i.e., it could be installed on an unfractured bone to give the same support and forstall the occurrence of a fracture. This use is intended to be encompassed in the pro tection of the appended claims.
- a surgical device particularly for joining segments of an elongated broken bone such as a femur bone, comprising a first member connectable to at least one segment of the bone so as to extend longitudinally of the latter, said first member having a first aperture; an adjustable second member slidably mounted on said first member and having a second aperture, each of said apertures being tapered and defining on each of said members a pivot point; fixing means for fixing said first and second members in one of a plurality of relative positions; and elongated means arranged to pass through and pivot about the pivot points of each of the respective apertures and be securely fixed at one end portion to at least another of the bone segments while having another end portion arranged to abut against said second member for holding said other bone segment to said second member, said elongated member forming an angle with the elongation of said first member, and thereby of the bone which is a function of the relative position between said first and second members.
- each of said apertures taper in diameter in a direction away from the bone.
