Abstract: This trunk rotation device uses dynamic movement of one's body such as, shoulder, hip, knee, back, thigh, and abdominal musculature. The device provides a method for exercising the spinal column and the muscles of the torso, including those in the abdominal lumbar and thoracic regions involving rotational torque. In a preferred embodiment, the device is a golf exercise and flexibility apparatus. The golf exercise apparatus provides resistance to a golfer during a golf swing to strengthen and condition the muscles of the axial skeleton of the golfer in a functional posture.

Abstract: A removable anchoring pedicle screw includes an implant mounting screw, an anchor screw, and a nose piece. The anchor screw is configured to be rotated relative to the implant mounting screw such that the nose piece engages an expandable anchor. The expandable anchor is disposed between the implant mounting screw and the nose piece such that rotation of the anchor screw relative to the implant mounting screw causes expansion of the expandable anchor.

Abstract: A fixation assembly having one or more insertions member that include one or more expandable and retractable anchoring inserts positioned along at least a portion of the insertion member and methods of use thereof are disclosed.

Abstract: The method and system of this invention provides for core muscle strengthening. The method comprises the step of: providing an apparatus (10) that provides resistance and assistance during core muscle training using dynamic therapeutic movement for chest, back, abdominal and leg musculature to strengthen and condition muscles of the axial skeleton and lower extremities of a performing user. In one embodiment, the method also is for non-invasive physical therapy.

Abstract: An articulating fusible support cage comprises a first support member having a first and second end and a second support member having a first and second end. A first end cap is pivotally connected to the first and second support members at the first ends. The first end cap supports a jackscrew for rotation. A second end cap is pivotally connected to the first and second support members at the second ends opposite the first ends. The second end cap has a threaded sleeve configured to engage a portion of the jackscrew. Rotation of the jackscrew into the threaded sleeve causes the first and second support members to extend outwardly from a collapsed condition to a deployed condition.

Abstract: Methods and apparatuses for performing highly accurate surgery using a finite element model coupled with ultrasonic tracking are described.

Abstract: The present invention discloses a nut to be used in a spinal screw and plate assembly to affix the screw and plate assembly to the spinal bone. The nut has a polymer insert that when contacted with a screw allows a bone plate and screw structure to relax over time.

Abstract: An apparatus for connecting a structure with a vertebral body of a spinal column and for transmitting a load between the structure and the vertebral body. The apparatus includes a fastener with a threaded portion for threaded engagement with a surface defining an opening in the vertebral body to connect the vertebral body with the structure. A spacer is adapted to be located between the fastener and the structure for transmitting load therebetween. The spacer is made of a material which plastically deforms as a function of time and load applied thereto to decrease the load transmitted between the vertebral body and the structure.
