Publication number: 20230389964Abstract: Correction of a scoliotic curve in a spine includes the steps of implanting an expanding rod isolated completely under the skin and attached to selected portions of the scoliotic curve of the spine at opposing ends of the rod; and producing a controlled force by means of expansion of the rod over at an extended time period under external control until a desire spinal curve is obtained. An incremental force is generated to stretch the scoliotic curve of the spine between the selected portions where attachment of the rod is defined. The controlled force is provided steadily for at least one month or alternatively 1-3 months. Multiple rods may be employed with each associated with a different scoliotic curve of the spine or a different portion of the scoliotic curve.Type: ApplicationFiled: June 9, 2023Publication date: December 7, 2023Inventor: P.

Publication number: 20120191138Abstract: In one embodiment, an orthopedic plate system is provided, comprising one or more orthopedic plates, each having one or more openings, a plurality of screws for securing one or more bones to said plates through said openings, and, means for flexibly locking said screws to said plates so that controlled motion of said bones is enabled after the securing of said bones to said plates. One advantage of said system is that of enhancing the healing of said bones and/or their fractures. A screw and bushing assembly, which flexibly locks said screw to an orthopedic plate, and a method of installing said orthopedic plate, are also disclosed.Type: ApplicationFiled: January 21, 2011Publication date: July 26, 2012Inventor: P.

Publication number: 20100094302Abstract: A spinal distraction system includes an adjustable spinal distraction rod having first and second members, the adjustable spinal distraction rod configured for non-invasive elongation of the first and second members. The system includes an anchor rod configured for mounting to a bone of a subject, and a socket coupled to the anchor rod, the socket having a lumen dimensioned to receive an end of a first member, wherein the end of the first member is configured for telescopic sliding movement within the lumen of the socket and wherein the second member is configured for mounting to a second bone of a subject.Type: ApplicationFiled: October 13, 2008Publication date: April 15, 2010Inventors: Scott Pool, Arvin Chang, P.

Publication number: 20090299370Abstract: A locking fracture plate may become a dynamic locking plate with the removal of a single set screw. The set screw removal may be done at the time of the initial implantation of the fracture plate, or several weeks later after the fracture has been allowed to consolidate. The device of the present invention may allow for the set screw to be removed percutaneously under x-ray control. The dynamized plate may allow for fracture compression but not for fracture displacement (loss or reduction) by rotation or sheer. The dynamized plate, with the set screw removed, may still protect the fracture from rotation and sheer. While conventional fracture plates may rigidly hold the bones in place, thereby potentially slowing bone fusion, or, in extreme cases, resulting in nonunion of the fracture, the fracture plate of the present invention may allow for fracture compression and, therefore, permit bone healing, growth and repair.Type: ApplicationFiled: May 29, 2008Publication date: December 3, 2009Inventor: P. Douglas Kiester

Publication number: 20090287220Abstract: Apparatus and methods for percutaneous screw extraction from orthopedic plates are described. The screw extractor eliminates the need for relatively large incisions to expose an orthopedic plate for the replacement of failed screws in the plate. The present invention further provides a device to function with slightly modified screws that allows the screws to be removed quickly, easily, and safely, with no larger incisions than were used to install the plate.Type: ApplicationFiled: November 14, 2008Publication date: November 19, 2009Applicant: CBRK ENTERPRISESInventor: P.
