Methods and systems for adjusting an external fixation frame

A method of correcting a deformity of a bone in a patient, the method comprising:

• coupling a first fixation ring to a first bone element of the patient;
• coupling a second fixation ring to a second bone element of the patient;
• coupling the first fixation ring to the second fixation ring using a plurality of adjustable-length struts:
• receiving correction plan data in a tool, the correction plan data for implementing a correction plan to correct the deformity, the correction plan data including information for adjusting one of the plurality of adjustable-length;
• determining, via a processor operably coupled to the tool, a prescribed length change of the one of the plurality of adjustable-length struts based on the correction plan data;
• while the tool is engaged to the one of the plurality of adjustable-length struts, operating a motor of the tool to rotate a driver of the tool and thereby rotate a screw of the one of the plurality of adjustable-length struts to start adjusting a length of the one of the plurality of adjustable-length struts according to the prescribed length change determined by the processor;
• while the length of the one of the plurality of adjustable-length struts is being adjusted, measuring an angular position of the driver using an angular position sensor operably coupled to the tool;
• and
• based on the measured angular position of the driver, determining whether the one of the plurality of adjustable-length struts has been completely adjusted according to the prescribed length change.
