Benefits of technology

[0010]According to invention, a system for determining and placing spinal implants or prostheses includes means for measuring a spatial change in position of vertebrae at an affected level of a patient's spine from a position of pain (POP) where the patient reports experiencing a greatest pain determined to originate from the affected level,

Problems solved by technology

Because any given surgeon's intuition is usually based on his or her training and the fellowship program they completed, the current practice of evaluating patients' spines and identifying implant devices to treat suspected abnormalities is fraught with uncertainties and results in patient outcomes that vary widely.
And, pain alone can not be detected by way of an x-ray or scan.

example one

[0039]Patient 1 is positioned and attached to a mobile surgical table 102 such as, e.g., the SpineSix table mentioned above. The patient controls the table 102 to move his / her spine into extremes of flexion, extension, bending, rotation, distraction and compression. The patient then manipulates the table to position their spine in a position where he or she experiences maximum pain (POP). The table position is recorded in terms of degrees of flexion, extension, bending, rotation, distraction and compression.

[0040]FIG. 13 is a radiographic image (plain x-ray) of the patient's spine in the POP, obtained from a scanner 104 in FIG. 12. The image, which may be taken and recorded digitally, is a plain lateral x-ray in which selected angles of lordosis and kyphosis associated with the motion segment are measured. In this example, MRI images are preferred instead of plain x-rays so that anatomical characteristics of the patient's POP and POC can be quantified once the positions are determin...

[0045]Patient 2 is positioned and attached to the mobile table 102. The patient controls the table 102 to move his / her spine into extremes of flexion, extension, bending, rotation, distraction and compression. The patient then manipulates the table to a position where he or she experiences maximum pain (POP). The table position is recorded in terms of degrees of spinal flexion, extension, bending, rotation, distraction and compression.

[0046]MRI radiographic lateral and coronal images of the patient's spine in the POP are taken separately by the scanner 104 and recorded. FIG. 18 shows the sagittal (lateral) view of the MRI taken with patient 2 in the POP. The image of FIG. 18 reveals anterior shift of L4 on L5 which is consistent with instability at that level and therefore presumed to be a spinal level of pain. Further, the image shows a posterior shift of L5 on S1 which is consistent with instability at that level and is therefore also presumed to be a spinal level of pain. Accordi...

Abstract

A system for determining and placing spinal implants or prostheses includes apparatus for measuring a change in position of vertebrae at an affected level of a patient's spine from a position of pain where the patient reports greatest pain originating from the affected level, to a position of comfort where the patient reports the least pain from the affected level. Spinal implants or prostheses are constructed and arranged for urging the affected level of the spine to the position of comfort when applied to or placed at determined locations in the affected level. In one embodiment, an implant device includes one or more inflatable balloons, wherein each balloon is placed at a certain location in a disc space at the affected level, and vertebrae above and below the balloon are urged to the position of comfort at the affected level when the balloons are inflated.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation-in-part (CIP) of my co-pending U.S. patent application Ser. No. 12 / 215,097 filed Jun. 25, 2008, and titled “System for Determining Spinal Implants”. The '097 application claims priority under 35 U.S.C. §119(e) of U.S. Provisional Patent Application No. 60 / 937,055 filed Jun. 25, 2007, and titled “System for Treatment of Spinal Abnormalities Using Patient Selected Positions”.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention concerns implant or prosthesis devices and systems for the treatment of spinal abnormalities.[0004]2. Discussion of the Known Art[0005]Surgeons and clinical practitioners use radiographic tools such as MRI scans and X-rays, together with their experience and intuition, to evaluate if a patient's spine is configured within a so-called “normal” range. If not, the surgeon then decides how much restoration or positional variance must be imparted to the sp...
