(Cl. 12892) ABSTRACT OF THE DESCLQSURE An improved tapered intra-medullary spinal fixation rod having a drill tip at the tapered end and the method of using the rod to support a human spine by drilling the rod through successive vertebrae.

The present invention relates to bone surgery, and pertains more particularly to a means for and method of positioning and supporting a spine.

In the case of a malformed spine, or one weakened by injury or disease, it frequently would be of inestimable value if the spine could be brought toward its normal or correct shape and maintained in that position. It is common practice in some bone breaks, for example, the neck of the femur, to insert a metal pin lengthwise through the two parts of the bone to secure them in properly set position. Prior attempts have been made to stabilize the spine by metal pins and plates embedded alongside the spine, and by various orthopedic harnesses strapped onto the body, but to date no known prior means or method has provided satisfactory, and if necessary permanent, positioning and stabilization for a malformed, weak or injured spine.

The present invention is directed toward the positioning and stabilizing of a human spine.

A further object of the invention is to provide an improved intra-medullary spinal fixation rod for inserting through the centrum of each of a plurality of adjacent vertabrael processes of a human spine.

A further object of the invention is to provide an elongated, tapered rod with a drill tip thereon, the rod and drill tip being of a metal which will be tolerated by, and stable within, a human body, the rod and drill tip being formed for drilling into and through a plurality of successive spinal vertabrae to support, stabilize and the spine in which such vertebrae are located.

A further object of the invention is to provide an improved method for positioning and stabilizing a plurality of adjacent spinal vertebrae by inserting through the centrum of the vertebral process of each of such vertebrae a metal rod, and then, if the rod is to remain therein, severing the rod at a point below the spine which will be Within the body upon healing.

A further object of the invention is to provide an improved method for positioning and stabilizing a human spine which comprises inserting a stabilizing rod through a plurality of successive vertebrae of such spine while observing by radiograph the forward tip of the rod as it proceeds along its course.

The foregoing objects and advantages of the invention will be apparent from the following description and the accompanying drawings, wherein:

FIG. 1 is a somewhat diagrammatic, perspective view showing the insertion of an intra-medullary spinal fixation rod in accordance with the present invention.

FIG. 2 is an enlarged, side elevational view of a preferred form of spinal fixation rod embodying the invention.

FIG. 3 is a similar view in reduced scale of a curved spinal fixation rod which can be employed where a slight curvature is desired.

FIG. 4 is a somewhat diagrammatic, side elevational view of a spinal column with the skull and a portion of the rib cage attached, the broken line showing the location of a spinal fixation rod inserted in accordance with the invention.

FIG. 5 is a plan view of a thoracic vertebra with the target location of the rod in the centrum indicated by the dotted line circle.

Briefly, in the illustrative form of the present invention, an intramedullary spinal fixation rod or pin 10 preferably is tapered as shown in FIG. 2 with the leading end thereof in the form of a drill tip 11. The rear or driving end of the rod 10 is adapted to be chucked in a suitable drill, such as that A shown in FIG. 1.

The rod 10 preferably is inserted in the peri-anal region or through the colon and thence onto the lower end of the spine 12 (FIG. 4) by drilling through the sacrum. The rent in the colon can be repaired after the rod has been driven through it. The rod 10 is guided to course upwardly through the centrum of each successive vertebra until a desired penetration has been achieved. The lower end of the rod 12 may then be severed, and the portion which has penetrated the spine remains in position therein. During the insertion of the rod 10, the progress of the leading end thereof preferably is followed by radiograph observations.

Referring to the drawings in greater detail, a presently preferred spinal fixation rod 10 (FIG. 2) is of suitable metal, which is relatively inert, and which will be well tolerated within the body, for example, a metal of the type used in the making of an intramedullary rod or nail of the type used for pinning broken bones, such as a bone of the leg or arm. The rod 10 is gradually tapered from the rear or driving end 13 toward the forward or leading tip end 11, since the vertebral bodies 12a, forwardly of the spinal cord 14 (FIG. 5), through which the rod 10 is inserted are of smaller size toward the upper end of the spine than they are toward the lower end thereof.

The rear or driving end 13 of the rod 10 is adapted to be chucked in the chuck 15 of a suitable drill, such as the usual half-inch electric drill A (FIG. 1) having a conventional AC-DC motor and employing a well known type of electronic speed control mechanism (not shown) employing a silicon rectifier to change AC line current to half-wave DC and a potentiometer, and employing a feed-back circuit to provide adequate torque at low speeds.

The forward tip portion 11 of the tapered rod 10 is in the form of a drill, the specific type of drill not being a feature of the present invention provided it is suitable for drilling through bone. Most of the path of the drill, as is obvious from the dotted line 17 indicating such path in FIG. 4, is in comparatively soft, inner bone structure and cartilage, although at the zone of entry into the sacrum it is, of course, harder.

It is not always necessary that the rod 10 be stiff, and it may be desirable in some instances that it be quite bendable either in part or throughout its entire length. It is obvious from FIG. 4 that in order to insert the rod 10 into the spinal processes of the upper thoracic region, and thence, if necessary, on into those of the cervical region, a bending of the rod 10 will be essential. Such bending can be accomplished, for example, by empioying a slightly bendable rod with a slightly offset tip thereon and drilling to the maximum distance wherein the spine can be manipulated into a sufiiciently straight position to permit such drilling. From this point on the rod can be driven, the rod being turned to direct the offset tip toward either the front or back as required, by rotatively moving the rod through an angle of Such positioning of the offset tip will cause a deflection of the tip along a desired path, the rod being sufliciently flexible to permit it to follow such gradually deflected path. Another means for inserting the rod along a curved path is to employ a flexible rod with a drill tip on the leading end thereof oflset to one side slightly so as to cause the drill tip to drift in the direction in which the tip is offset when the rod is oscillated, and to follow a straight course when the rod is rotated.

Some changes in the alignment of successive vertebrae, at least those of the lumbar region is usually possible by manipulation of the body of the subject as the drill advances from one vertebra to the next, thereby to maintain the drill tip on its desired course. The requirement for a more or less flexible rod, and a curving or drifting course for the tip 11 becomes necessary only in cases of an uncorrectable curvature, or for advancement of the rod into the upper portions of the spine, where the presence of the rib cage restricts such manipulation.

A presently preferred method for inserting the rod 10 into a spine 12 is as follows:

The drill tip 11 is introduced in the peri-anal region, or through the colon. The progress of the tip 11 of the rod 10 is observed at required intervals throughout the insertion procedure by radiograph observation, preferably employing two X-ray machines 20 and 21 with their ray axes directed toward a desired point along the spine, and offset from each other through a selected transverse angle, preferably of approximately 90 as shown in FIG. 1.

The rod 10 is directed so that it passes through the sacrum and enters the centrum of the spinal process of the lowermost lumbar vertebra. Thence it is directed along a course through the centrum of each successive vertebra until a desired penetration has been attained, for example, when the zone of the spine which it is desired to straighten or stabilize has the rod inserted therein. The rod 10 is then released from the drill chuck 15, and is cut off as by means of a bolt cutter (not shown) at a desired point, preferably a point which will be within the body after healing if the rod is to remain in place permanently. If the rod is to be removed after a spinal healing process has occurred, the rod is allowed to project so that it can be manipulated as required for its withdrawal.

If it is necessary to advance to rod 10 to a point in the spine which cannot be reached with a straight rod, a rod of suitable flexibility is employed, and is guided in its course from one vertebra to the next as required and as set forth previously herein. Also, in some cases, it might be desirable to insert a pro-formed rod such as that 10a shown in FIG. 3.

The invention provides a means and method for straightening and strengthening malformed, injured, diseased and weakened spines whereby it is possible to restore to almost normal condition and use, many persons who at present are suffering from such spinal conditions.

While I have illustrated and described a preferred embodiment of the present invention, it will be understood, however, that various changes and modifications may be made in the details thereof without departing from the scope of the invention as set forth in the appended claims.
