Systems and methods for detecting fixation frame parameters
View Patent ↗A detection device, such as a camera-enabled smart phone, may be used to take one or more pictures of an external fixation frame attached to a patient. The pictures may be transmitted to a computer system accessible by the patient's physician. The computer system may uniquely identify each strut of the external fixation frame and determine the length of each strut. The computer system may compare the determined length of each strut to a planned length of the struts for a particular time interval as outlined in a correction plan. If the struts are the correct length for the particular time interval, the fact may be indicated to the physician and transmitted to the patient. If the struts are not the correct length, the computer system may update the correction plan to account for the discrepancy plan, with the updated correction plan transmitted to the patient.
1. A computer system including at least one processor configured to execute instructions to:
receive a plurality of images of an external fixation system coupled to a patient, each image containing at least one strut of the external fixation system;
determine a length of the at least one strut in each image;
identify the at least one strut in each image corresponding to a predefined correction plan for the at least one strut in each image;
compare the determined length of the at least one strut in each image to a planned strut length of the predefined correction plan, the planned strut lengths being stored in memory of the computer system;
update the predefined correction plan to an updated correction plan to account for differences between the determined length and the planned strut length, the updated correction plan and the predefined correction plan having the same final configuration of the external fixation system;
transmit the updated correction plan for adjusting the struts of the external fixation system.
2. The computer system of claim 1 , wherein the instructions to identify the at least one strut in each image comprise comparing visual indicia on the at least one strut to corresponding indicia stored in the memory.
3. The computer system of claim 2 , wherein the visual indicia is a quick response (QR) code.
4. The computer system of claim 1 , wherein the planned strut lengths stored in memory include a length component and a time-interval component.
5. The computer system of claim 4 , wherein the at least one processor is further configured to execute instructions to receive a time indicator corresponding to each of the plurality of images.
6. The computer system of claim 5 , wherein the instructions to compare the determined length of each of the plurality of struts to the planned strut length further include comparing the time indicator corresponding to each of the plurality of images to a time-interval component of the planned strut length.
7. A computer system including at least one processor configured to execute instructions to:
receive a plurality of images of an external fixation system coupled to a patient, each image containing at least one strut of the external fixation system;
determine a length and an identity of the at least one strut in each image;
compare the determined length of each of the plurality of struts to a corresponding planned strut length, the corresponding planned strut lengths being stored in an original correction plan in memory of the computer system;
update the original correction plan to an updated correction plan to account for differences between the determined length and the planned strut length, the updated correction plan and the original correction plan having the same final configuration of the external fixation system; and
transmit the updated correction plan for adjusting the struts of the external fixation system.
8. The computer system of claim 7 , wherein the instructions to determine the identity of the at least one strut in each image comprise comparing visual indicia on the at least one strut to corresponding indicia stored in the memory.
9. The computer system of claim 8 , wherein the visual indicia is a quick response (QR) code.
10. The computer system of claim 7 , wherein the corresponding planned strut lengths stored in memory include a length component and a time-interval component.
11. The computer system of claim 10 , wherein the at least one processor is further configured to execute instructions to receive a time indicator corresponding to each of the plurality of images.
12. The computer system of claim 11 , wherein the instructions to compare the determined length of each of the plurality of struts to a corresponding planned strut length further include comparing the time indicator corresponding to each of the plurality of images to a time-interval component of the planned strut lengths.
13. A computer system including at least one processor configured to execute instructions to:
determine a predefined correction for an external fixation system including a plurality of adjustable length struts, the predefined correction plan including for each of the plurality of adjustable length struts an original length and a final length;
receive a plurality of images of the external fixation system coupled to a patient, each image containing at least one strut of the external fixation system;
determine a length of the at least one strut in each image;
identify the at least one strut in each image corresponding to a time-interval in the predefined correction plan for the at least one strut in each image;
compare the determined length of the at least one strut in each image to a planned strut length at the time-interval in the predefined correction plan, the planned strut lengths being stored in memory of the computer system; and
update the predefined correction plan to an updated correction plan to account for differences between the determined length and the planned strut length, the updated correction plan and the predefined correction plan having the same final configuration of the external fixation system; and
transmit the updated correction plan for adjusting the struts of the external fixation system.
14. The computer system of claim 13 , wherein the instructions to identify the at least one strut in each image comprise comparing visual indicia on the at least one strut to corresponding indicia stored in the memory.
15. The computer system of claim 14 , wherein the visual indicia is a quick response (QR) code.
16. The computer system of claim 13 , wherein the planned strut lengths stored in memory include a length component.
17. The computer system of claim 16 , wherein the at least one processor is further configured to execute instructions to receive a time indicator corresponding to each of the plurality of images.
18. The computer system of claim 17 , wherein the instructions to compare the determined length of each of the plurality of struts to the planned strut length further include comparing the time indicator corresponding to each of the plurality of images to the time-interval component of the planned strut length.
