摘要:
A bone cut system comprising a distractor, one or more drill guides, one or more bone cutting jigs, a computer, and a display. The distractor includes electronic circuitry configured to control a measurement process and transmit measurement data. The distractor can include a magnetic distance sensor, a magnetic angle sensor, and load sensors configured to measure a distraction distance, medial-lateral angle, load magnitude applied to the distractor, and position of load in real-time. The distractor equalizes a medial and lateral compartment of a knee joint in flexion or extension at a predetermined loading. Guide holes are drilled to support cuttings with the medial and lateral compartments equalized. The distractor is configured to support one or more bone cuts using cutting jigs coupled to the guide holes that supports installation of a prosthetic component in alignment with a mechanical axis of a leg.
