SYSTEMS AND METHODS FOR MEASURING RELATIVE ORIENTATION AND POSITION OF ADJACENT BONES |
| 摘要 |
A method for estimating leg length and offset, comprises registering an anatomic coordinate frame associated with a patient's pelvis. The method also comprises measuring a first position of a femur relative to the patient's pelvis. The method further comprises receiving, from magnetic and orientation sensors, information indicative of a change in a position of the femur relative to the pelvis of the patient's pelvis. Alternatively, the method further comprises receiving, from light and orientation sensors, information indicative of a change in a position of the femur relative to the pelvis of the patient's pelvis. The method also comprises determining at least one of a leg length and an offset based on the first position and the change in position. |

1. A method for estimating leg length and offset, comprising:
registering an anatomic coordinate frame associated with a patient's pelvis; receiving, from at least two magnetic sensors, information indicative of a first position of a femur relative to the patient's pelvis; receiving, from the at least two magnetic sensors, information indicative of a change in a position of the femur relative to the patient's pelvis; and determining at least one of a leg length and an offset change based on the first position and the change in position. |
