Definitions

  • ABSTRACT A sleeve is to be inserted into a fractured bone bridging the fracture thereof. The leading end portion is then to be located in one bone fragment and the open trailing end portion is to communicate with the exterior of the other bone fragment.
  • An expander screw is threaded into the sleeve and has a head which bears exclusively upon an annular shoulder provided on the sleeve. The front end of the expander screw serves, by its configuration or by cooperation with an expander element, for
  • a cap screw is threadedly connected with and closes the trailing end portion of the sleeve, bearing upon the other bone fragment and thereby drawing the two fragments together via the intermediary of the sleeve.
  • the present invention relates generally to a connector for fractured bones, and in particular to a connector for use in case of fractures of the neck of the femur, that is the upper thigh bone.
  • an object of the present invention to provide a connector for bone fragments, particularly but not exclusively for fractured femurs, which is not possessed of these disadvantages.
  • a concomitant object of the invention is to provide such a connector which makes it possible to immediately put stress on the fractured bone without doing any damage.
  • a connector for fractured bones which comprises a sleeve adapted for insertion into a fractured bone bridging the fracture thereof, and having a leading end portion adapted to be located in one bone fragment and an open trailing end portion adapted to communicate with the exterior of the other bone fragment.
  • Expander means is provided for expanding the leading end portion and includes an expander screw threaded through the sleeve and having a head portion located within the trailing end portion engaging and bearing only upon the same when the screw is rotated in a sense effecting expanding of the leading end portion.
  • a cap screw is threadedly connected with and closes the trailing end portion of the sleeve.
  • a connector constructed according to the present invention fulfills the requirements which have been outlined above. It can be readily installed in that a nail is first driven in conventional manner into the two bone fragments to be connected. In the case of a fractured femur the nail is driven centrally at the requisite angle into the neck of the femur. Now the sleeve of the connector according to the present invention is placed around the nail and driven into the bone, and subsequently the nail is withdrawn because it is no longer needed. The expander means is now utilized for expanding the leading end portion of the sleeve whereby the latter is anchored in the bone.
  • the head of the expanding screw bears only upon the sleeve itself so that the entire axial force necessary for effecting the expansion of the leading end portion of the sleeve acts only upon the latter, and not upon the bone. This prevents damage to the bone.
  • the cap screw is threaded onto or into the trailing end of the sleeve and its cap screw head engages and bears upon the exterior of that bone fragment in which the end portion of the sleeve is embedded. Turning of the cap screw in a sense threading it more deeply onto the sleeve exerts pull upon the sleeve whereby the two bone fragments are drawn together and the gap at their fracture line is reduced or eliminated.
  • the bone fragments should touch each other at the fracture line and in this manner the bone fracture will heal much more rapidly than heretofore possible.
  • the bone fragments now are in contact with one another rather than being spaced from one another as in the prior art, so that stress can immediately be placed on the fractured bone once it has been connected with the connector according to the present invention. 7
  • the connector is no longer needed. At that time, therefore, the cap screw is unthreaded from the sleeve, and the expanding screw is similarly unthreaded and removed.
  • the expander member if a separate one has been employed which of course is located at the leading end of the sleeve, is dislodged in suitable manner, for instance by exerting a brief blow upon the screw before the latter is unthreaded, so that the expander member returns to its original position and permits the leading end of the sleeve to resiliently return to its original configuration, making it possible to subsequently remove the sleeve also.
  • the rear or trailing portion of the sleeve has a stepped outer diameter, meaning that its outer diameter is less than that of the remainder of the sleeve.
  • This portion of reduced outer diameter is provided with external screw threads which mesh with internal screw threads in the tubular stem of the cap screw whose outer diameter corresponds to the outer diameter of the remainder of the sleeve.
  • leading end portion of the sleeve at its open leading end with an inwardly directed flange which prevents the undesired emergence from this leading end of the expander member, and consequently prevents the expander member from becoming dislodged from the sleeve.
  • the leading end portion of the sleeve which is to be expanded may be surrounded with an elastic jacket.
  • an elastic jacket makes the formation of callus in and around the segments impossible so that they can return to their original undeflected position when the expander member is dislodged, and the sleeve can then be properly removed.
  • the front portion of the expander screw is also possible to construct the front portion of the expander screw as a pin having a conical or otherwise configurated leading end which, when the screw is threaded deeper into the sleeve, serves to expand the expander member itself rather than drawing the latter into the sleeve for expanding the same.
  • the connector according to the present invention can be successfully used even for repairing bone fractures in children without unduly weakening the bones of children-which are not yet very large-with'a large hole driven into them.
  • thecap screw in such a manner that its stem does not exteriorly surround the trailing or rear end portion of the sleeve, but instead fits into the interior of the latter.
  • the stem of the cap screw must be exteriorly threaded to mesh with interior threads of the sleeve, and according to the invention the threads onthe stem and the threads on the expander screw, or on the screw portion of the expander pin, will be identical whereby a simple and inexpensive manufacture of the various components is further facilitated.
  • FIG. 1 is a diagrammatic sectioned illustration showing one embodiment of the invention connecting the fragments of a fractured femur;
  • FIG. 2 is a view similar to FIG. 1 but showing another embodiment of the invention.
  • reference numerals 6 and 6' identify the two bone fragments into which a femur has become separated due to a fracture.
  • these two bone fragments have been properly aligned with reference to one another in the manner in which they were originally positioned when the bone was not yet fractured In this manner they are connected by means of the illustrated connector according to one embodiment of the invention.
  • Reference numeral 1 identifies the connector in toto and it is to be understood that preferably the components of the connector are manufactured of rust-free steel, for instance of steel known under the designation V2A or that known under the designation V4A.
  • the connector 1 comprises an expansion sleeve 2, whose front end portion is driven into the bone fragment 6, whereas its rear end portion is located in the bone fragment 6 through which the front end portion was originally driven.
  • the rear end of the trailing or rear end portion of the sleeve 2 is open to the exterior of the bone fragment 6', as illustrated.
  • an expander portion 3 Located at the front end portion of the sleeve 2 is an expander portion 3, and the rear end portion which is stepped, that is which has a lesser outer diameter than the remainder of the sleeve 2, is identified with reference numeral 4. It is also exteriorly threaded and an interiorly threaded tubular stem of a cap screw can be threaded onto it as shown in FIG. 1.
  • an expander element 7 which can mesh with the expander screw 8 threaded into the interior of the sleeve 2.
  • the head 9 of the expander screw 8 is of such dimensions that it engages the rear end face at the rear end of the sleeve 2 as shown in the drawing, or else it can actually be located within the sleeve and engage an inner annular shoulder provided for this purpose.
  • the sleeve 2 is exteriorly provided with projections 10 or other similar means for preventing its rotation with reference to the bone fragments 6, 6.
  • the cap screw is threaded onto the trailing end portion 4 of the sleeve 2.
  • the cap screw 5 is provided with a cap screw head or flange 11 which bears upon the exterior of the bone fragment 6'.
  • a washer 12 As illustrated.
  • annular groove I3 is provided on the sleeve 2 exteriorly encircling the same at the junction with the expander portion 3.
  • An elastically deflectable jacket 14 is pushed onto and surrounds the expander portion 3 and is expanded together with the latter, the purpose being to prevent the growth of callus between the sections of the expander portion 3. The jacket 14 is removed together with the sleeve 2 when the fracture is healed.
  • the expansion of the expander portion 3 is effected by constructing the expander memberv 7a as an actual portion of the screw serving for expanding purposes, or, putting it conversely, to construct the screw in a pin-shaped configuration having a tapering leading end 17 as illustrated and an exteriorly threaded head 15 which meshes with the interior threads in the sleeve 2.
  • the expander portion 3, having a bore corresponding to the tapering configuration of the leading end portion 17, is expanded by threading thev screw head 15 deeper into the sleeve 2 in a sense advancing the pin 7a forwardly, that is towards the left in FIG. 2.
  • the bone fragments 6 and 6' are drawn together into abutment by threading the cap screw 5a into the interior threads of the sleeve 2 as illustrated.
  • the stem of the cap screw is exteriorly threaded as will be appreciated.
  • Reference numeral 16 identifies a slot in the head 15 of the pin 7a for facilitating turning of the latter.
  • the washer 12a can be configurated in such a manner--compare the single or plural projections l2b--that it will serve not only to increase the abutment'surface between the head of the cap screw 5a and the bone fragment 6', but also will serve as a retaining element for preventing undesired loosening of the cap screw 5a for which purpose it is provided-in addition to the projections l2bwith a tongue 12cv engaging and preventing turning of the head of the cap screw 5a.
  • a further advantage is the fact that the connector according to the present inven tion has an identical diameter over its entire exterior-this being true in FIG. 1 also when the cap screw is connected with the sleeve-and thereby can be produced in a simple and relatively inexpensive manner, and also can be very readily and simply inserted into the bone fragments.
  • Sleeve 14 may be of synthetic plastic, elastically deflectable steel, or the like.
  • a connector for fractured bones comprising a sleeve adapted for inserting into a fractured bone bridging the fracture thereof, and having a leading portion adapted to be located in one bone fragment and an open trailing portion adapted to communicate with the exterior of the other bone fragment and provided with an endface and with internal threads inwardly of said endface; expander means for expanding said leading portion, and including an expander screw threaded through said sleeve and having a head portion located in said trailing portion axially bearing upon the same when said screw is rotated in a sense effecting expanding of said leading portion; and a cap screw having a stem threaded into said trailing portion of said sleeve and a cap screw head adapted to exteriorly engage and bear upon said other bone fragment, the threads of said screws being identical.
  • said expander means including an expander element, and cooperating engaging means on said element and said expander screw for drawing the former into said sleeve in a sense expanding the same in response to rotation of said expander screw.
  • said expander means comprising an expander member, and an expander pin portion on said screw operative for expanding said expander member in response to advancement of said expander pin portion longitudinally of said sleeve due to rotation of said expander screw.
