Abstract: A method of treating a patient who requires surgical implantation of an orthopedic implant is described. The method includes the steps of: determining the DEXA scan T-score of the patient's native bone at a site of surgical implantation where the implant will be in contact with the patient's native bone; retrieve from among three or more implants of the same type an implant that has a density that is closest to the density of the patient's native bone at the site of surgical implantation based on the DEXA scan T-score of the patient's native bone; and implanting the retrieved implant in the patient to the exclusion of the other two or more implants.

Abstract: An interspinous fusion device is described. It includes a first member with a column of teeth, and a second member with a column of recesses adapted to mate with the column of teeth of the first member. The first member and the second member have opposing windows on their walls, such that when the first member is mated with the second member an unobstructed passage is formed through the opposing windows. The first member and the second member lock together when the teeth and recesses are mated, said locking occurring without the aid of a set screw, pin or other mechanical component.

Abstract: An interspinous posterior device (IPD) is described. The IPD has a body and bone fixation elements on either side of the body, each of said bone fixation elements having a ratchet locking mechanism for fixing the body to successive spinous processes of a mammalian vertebra. Each of the bone fixation elements is independently adjustable by ratcheting it separately and independently of the other bone fixation elements. The body of the IPD has a dynamic configuration and a non-dynamic configuration, wherein the dynamic configuration allows for both extension and flexion of the successive spinous processes and the non-dynamic configuration prohibits extension of the successive spinous processes. The IPD also includes a removable extension restriction block, wherein the extension restriction block can optionally be inserted in the body to prohibit extension or can be removed from the body to allow extension.

Abstract: A method of treating a patient in need of an orthopedic implant is described. The method includes obtaining the T-score or bone density of the patient's native bone at a site of implantation, said T-score or bone density being determined by a DEXA scan or other means of determining a T-score or bone density. The method further includes selecting an orthopedic implant that has about the same density as the native bone at the site of implantation, and implanting the orthopedic implant at the site of implantation.
