Abstract

The present invention is directed to a system and method for performing tissue, preferably bone tissue manipulation. The system and method may include implanting markers on opposite sides of a bone, fractured bone or tissue to facilitate bone or tissue manipulation, preferably in-situ closed fracture reduction. The markers are preferably configured to be detected by one or more devices, such as, for example, a detection device so that the detection device can determine the relative relationship of the markers. The markers may also be capable of transmitting and receiving signals. An image may be captured of the bone or tissue and the attached markers. From the captured image, the orientation of each marker relative to the bone fragment may be determined. Next, the captured image may be manipulated in a virtual or simulated environment until a desired restored orientation has been achieved. The orientation of the markers in the desired restored orientation may then be determined. The desired relationship between markers may then be programmed into, for example, the detection device. Next, actual physical reduction and/or manipulation of the bone may begin. During the manipulation procedure, the orientation of the markers may be continuously monitored and when the markers substantially align with the virtual or simulated orientation of the markers in the desired restored orientation, an indicator signal is transmitted.

Claims

1. A method of performing bone or tissue manipulation comprising the steps of:

implanting at least one marker on opposite sides of one or more bone, tissue or bone fragments, wherein the position of the markers is capable of being determined;

capturing an image of the bone, tissue or bone fragments with the markers attached;

manipulating the image of the bone, tissue or bone fragments in a virtual or simulated environment to a desired restored orientation;

determining the orientation of the markers in the desired restored orientation; and

manipulating the bone, tissue or bone fragments until an indicator signal is generated indicating that the desired restored orientation has been substantially achieved.

2. The method according to claim 1, wherein the markers are capable of transmitting a signal to an external device, the signal containing information as to the markers orientation.

3. The method according to claim 1, wherein the markers are capable of receiving a signal from an external device, the signal containing information as to the markers orientation.

4. The method according to claim 1, wherein the markers are capable of both transmitting to and receiving from an external device a signal, the signal containing information as to the markers orientation.

5. The method according to claim 4, further comprising the step of programming the implanted markers before manipulating the bone, tissue or bone fragments, the makers being programmed with the desired restored orientation and instructing the markers to communicate with an external device, the external device being capable of generating the indicator signal upon the markers being manipulated into the desired restored orientation.
