9 Claims, 5 Drawing Figures METHOD AND APPARATUS OF IMMOBILIZING A FRACTURED FEMUR CROSS REFERENCE TO RELATED APPLICATION This application is a continuation-in-part of my copending application entitled PRESSURE-CLAW- NAIL FOR FEMUR-NECK FRACTURES, Ser. No. 883,255, filed Apr. 13, 1970 now abandoned.
BACKGROUND OF THE INVENTION This invention relates to a device for immobilizing fractures of the neck of a femur.
One device which is commonly used for immobilizing a fractured neck of a femur comprises a three-lamellae nail which is hammered into the neck of the femur through the fracture region. With this nail there is no compression of the bone fragments in the fracture region, since the head of the femur rests loosely against the nail. The spongy bone in the interior of the femoral neck does not permit such a nail to effect sufficient holding together of the bone fragments without movement while healing takes place. Any small movements produced in the fracture region may cause the development of a femoral neck pseudoarthrosis (second joint).
Another device used is a compression screw, but although the screw thread has a greater hold on the spongy bone than the aforementioned nail and exerts compression on the bone fragments, since the compression screw is not provided with lamella the femoral head fragment is not fully prevented from rotating relatively to that neck fragment which is continuous with the femoral shaft.
OBJECTS AND SUMMARY OF THE INVENTION The main object of the present invention is to provide a device for immobilizing a fracture of the neck of a femur which is capable of effecting resilient compression of the bone fragments in the fracture region and of exerting a firm hold on the spongy bone so as to guard against rotation of the femoral head.
According to the present invention there is provided a device for immobilizing a fractured neck of a femur, the device including a tubular body member, four claw members which are mounted within the body member and which are movable simultaneously between positions in which the claw members are extended outwardly from, and are fully retracted into, the body member, the claw members being arcuate in cross section, being formed in such a manner as to press bone fragments of the neck of the femur together in the outwardly extended position when the device is in the neck of the femur and defining, in the fully retracted position, a part ofa duct for a guide wire, which extends axially throughout the device, and means for maintaining the device in position in the fractured neck of the femur.
BRIEF DESCRIPTION OF THE DRAWINGS In order that the invention may be more fully understood some embodiments in accordance therewith will now be described by way of example with reference to the accompanying drawing, in which FIG. I is an enlarged view partially in cross section and partially in elevation ofa device for treating a fracture of the neck of a femur, secured in position in a DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings there is shown, in FIG. 1, in dotted lines, the outline of the upper portion of a femur bone having a head s, a neck t and a shaft with the outer hard surface of the femur being designated e and the inner spongy bone e. The femoral neck t is fractured as represented diagrammatically by the dotted line i.
The device for immobilizing the fracture i e.g., in the position shown in FIG. 1, incorporates a tubular body member c having a nut a secured to one end thereof for rotation about the longitudinal axis of the member c. The'nut a is internally threaded and engages with a threaded rod b which projects axially into the body member 0. Claw members b shown in an outwardly extended position are secured. through a guide member (not shown) to the end of the rod b inside the body member c. The claw members b are movable simultaneously between positions in which they are extended outwardly from, and fully retracted into, the body member through apertures d. The guide member engages in four axial grooves (not shown) formed in the inner wall of the body member 0 to prevent rotation of the claw elements relatively to the body member c during their movement.
Each of the claw elements b is arcuate in cross section for reinforcing purposes as shown in FIG. 4.
Also, the claw members b are formed-in such a manner as to press the bone fragments of the fractured neck of the femur together in theoutwardly extended position, and define in the fully retracted position a part of a ductf" (see FIG. 5) extending axially throughout the deivce. The threaded rod b defines another part of the duct f.
In the fully retracted position the claw members define a substantially square central aperture.
Integral with the threaded rod b is another rod f which, as will be apparent from FIG. 5 is substantially square shaped in cross section with each of its corners being of arcuate shape and being provided with a screw thread f. The longitudinal surfaces of the rod f are smooth and are obtained by milling a screw-threaded rod. The rodfdefines another part of the axial duct,f for a purpose to be described. I
The device further includes a sleeve w having a nonthreaded portion n which projects into the femur when the device is in position in the femoral neck, a threaded nut portion h which threadedly engages with the rod fin the manner shown and an annular flange v. Inthe construction of FIG. 1 the annular flange v is connected to a wedge portion 1 as by a ball joint (not shown) for permitting relative movement between the nut portion 11 and the wedge portion p and to enable the wedge portion p to be firmly pressed against the femur in a manner to be described. A counternut is provided for securely locking the sleeve and the wedge p in the position shown in FIG. I. If the femoral shaft l4 has'been splintered or fractured at the same time as the fracture i, then, as is known, a plate k may be secured to the shaft u in the manner shown to align and immobilize these bone fragments. In this instance the plate k is secured to the rodfby the counternut 0.
In FIGS. 2 and 3 the construction of the sleeve w is modified, the wedge portion p being replaced by a toothed portion g which is integral with this modified sleeve w. The toothed portion 3 has teeth I which are made to bite into the femur during insertion of the device thereby ensuring secure fixing of the device in position in the femoral neck. The nut portion h, is replaced by a hollow clampable member having four resilient tooth-like segments h which slidingly engage with the longitudinal side surfaces of the rodf. A second nut 11 is screwed onto the rodfand exerts a clamping pressure on the segments h thereby securing the sleeve w to the rodf. In FIG. 2, the toothed portion g consists of circularly distributed teeth whereas in FIG. 3, the toothed portion g is divided into two wedge shaped portions.
When a three-lamellae nail having an axial bore is used for immobilizing the fracture, a surgical operation is performed so that after the appropriate area of the femoral bone has been exposed a 2mm. guide wire is drilled into the femoral neck until, under X-ray observation, the wire is in the correct position. At this stage the three-lamellae nail is pushed over a projecting end of the guide wire and hammered through the fracture into the desired position.
Using either of the devices described, however, when the guide wire is in the correct position, a hole is bored in the femoral neck using a hollow crown drill which is guided by the guide wire. The drill is ofa size which will permit fitting of the body member 0 in the bored hole without hammering. The hole depth required can be read from a scale on the outside of the crown drill. In order to fit the device in the femoral neck the sleeve w is removed from the rodf, and the body member 0, with the claw members b fully retracted, is pushed over the guide wire, the wire extending through the aperture defined by the free ends of the claw member and the duct j defined by claw members b, the rod b and the rod f. With the body member c in the position shown in FIG. 1, for example, the rodfis held to prevent it from rotating, while by means of a suitable tool, the nut a is rotated in the direction which effects axial movement of the rod 12, together with the rodf, so that the claw members b are moved into the outwardly extended position shown in FIG. 1. Rotation of the nut a is stopped when the free ends of the claw members have penetrated through the spongy bone :2 and bite into the inner surface of the firm outer layer e (cortex) of the femoral head s. Depending upon the size of the femoral head the claw members can be extended in the range of 5 to 7 cm.
In either of the cases of FIGS. 2 and 3, with the segments h of the nut portion 11, in engagement with the milled surfaces of the rodfthe sleeve w is slid along the rod for in the case of FIG. I the sleeve w is screwed along the rodf. The part n which is of the same diameter as the body member 0, is thereby inserted into the bored hole until the wedge portion p or teeth I of the toothed portion g abut against the exterior of the femur as the case may be. In FIG. 2, a box spanner r is fitted over the nut I1 so that it abuts against the surface In of the toothed portion g which spanner can then be hammercd until the required counterpressure is obtained. The spanner r is hammered until the teeth I of the portion g bite into the femur to prevent rotation of the device relative to the femur. Using the same spanner r the nut h is threaded onto the rod fand is tightened, so that the tooth-like segments are clamped onto the rod f to secure the device in position. The device of FIG. 3 can be similarly positioned using a spanner such as r. In the case of FIG. 1, the spanner r is slid over the rod f, engages with the nut portion h, of the sleeve w and is turned until the wedge portion p firmly abuts against the exterior of the femur to prevent any rotation of the device relative to the femur. In each case, the rodfis withdrawn slightly from the bored hole during securing thereby causing the bone fragments to be pressed firmly and resiliently against one another by means of the claw members b which prevent any relative rotation and movement during healing and re-ossification. Where a plate k is required, the nut 0 is screwed onto the rodfto firmly secure the plate k in position. Without a plate k the nut 0 can be used as a counter-nut and cooperates with the nut portion 12,. The guide wire is then removed.
After tightening of the nut portion h or nut h as the case may be, the claw members 19' exert a resilient effect, thereby closing any gap left between the bone fragments due to resorption prior to the operation.
When the fracture is healed and during a suitable operation the nut o and nut portion h or 11 as the case may be, are unscrewed, the sleeve w is withdrawn from the femur and the nut a is rotated in the direction which causes retraction of the claw member b into the body c and the device can then be easily removed. The portion n of the sleeve w prevents total closing of the bone during healing thereby permitting easy withdrawal of the device after retraction of the claw members [7.
The devices described ensure that the bone is firmly held so that movement of the particular device in the bone, and relative movement of the bone fragments of the fracture is guarded against. The bone fragments are firmly pressed together thereby facilitating healing, and resorption of the bone fragments along the fracture line is prevented due to the resilient effect of the claw members. Thus, the bone fragments are firmly held together until re-ossification has taken place.
