摘要：
A configurable check and balance system is provided to assess and report orthopedic measurements, including bone cut angles, trial inserts, extension gaps and prosthetic fit. The system can be configured for cut-check, trial-check, alignment and balance, dynamic distraction, and prosthetic trial fit. The measurements can be provided with respect to an anatomical coordinate system defined according to a positioning of a sensorized mechanical plate with respect to one or more referenced anatomical landmarks. In one example, the cut-check provides measurement of varus/valgus angle and anterior/posterior slope for distal femur cuts and proximal tibia cuts. The cut-check permits a surgeon to check bone cuts made by mechanical jigs, guides or patient specific implants (PSI). It also provides distance measurements. Other embodiments are also disclosed.
