摘要:
A method and apparatus for reliably positioning a 3-segment limb, such as a leg or arm for imaging and medical analysis, which can accommodate for the patient's “natural alignment”. The apparatus positions the limb in such a way that the position of the proximal segment is controlled while an known external torque is applied at a known rate to the distal segment. The location of each of the limb's three segments is recorded using either external or internal measurement techniques, and the relative motions between the proximal and intermediate segments are used in the orthopedic evaluation of the proximal joint. Furthermore, the relative motions between the intermediate and distal segments are used in the orthopedic evaluation of the distal joint. By applying a known torque at a known rate, clinicians will be provided with valuable information related to joint range of motion, stability, laxity, and compliance.
