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

1-20. -20. (canceled)

21. A method for performing tissue manipulation, comprising the steps of:

implanting first and second markers on first and second portions of tissue, respectively, wherein a position of each of the first and second markers is capable of being determined;

actuating an instrument to capture an image of the first and second portions of tissue with the first and second markers attached thereto;

manipulating the image of the first and second portions of tissue in a simulated environment to a desired orientation;

causing the instrument to determine positions of the first and second markers in the desired orientation; and

manipulating the patient until the desired orientation has been substantially achieved.

22. The method according to claim 21, wherein the first portion of tissue is a bony tissue.

23. The method according to claim 22, wherein the second portion of tissue is a bony tissue.

24. The method according to claim 21, wherein the instrument detects when the positions of the first and second markers indicate the first and second portions of tissue have arrived at substantially the desired orientation.

25. The method according to claim 21, further comprising:

generating, when the desired orientation has been substantially achieved, an indicator signal.

26. The method according to claim 21, wherein the first marker is a passive marker.

27. The method according to claim 21, wherein the second marker is a passive marker.

28. The method according to claim 21, wherein the first and second markers are configured to communicate with one another.

29. The method according to claim 28, wherein the communication between the first and second markers is continuous during the tissue manipulation.

30. The method according to claim 23, further comprising:

implanting a fixation device to fix the first and second portions of tissue in the desired orientation.

31. The method according to claim 21, wherein the instrument comprises one of an X-ray imager, a three-dimensional X-ray imager, computed tomography, a magnetic resonance imager and an ultrasound imager.

32. The method according to claim 22, wherein the first portion of tissue is a vertebra.

33. The method according to claim 22, wherein the first portion of tissue is a portion of a mandible.

34. The method according to claim 22, wherein the first portion of tissue is a portion of a long bone.
