Abstract

Technologies for generating a patient-specific surgical plan from medical image data include receiving an orthopaedic surgical plan request from a computing device of a healthcare facility via a network, receiving a medical image of bony anatomy of a patient, and receiving constraint data corresponding to an orthopaedic surgical procedure to be performed upon the bony anatomy of the patient. Such technologies may further include determining whether the orthopaedic surgical procedure to be performed upon the bony anatomy of the patient is a difficult orthopaedic surgical procedure, generating a first surgical plan for the orthopaedic surgical procedure to be performed in response to determining that the orthopaedic procedure to be performed is not a difficult orthopaedic surgical procedure, and generating a second surgical plan for the orthopaedic surgical procedure to be performed in response to determining that the orthopaedic procedure to be performed is a difficult orthopaedic surgical procedure.

First claim

The invention claimed is:

1. A method for generating a surgical plan for an orthopaedic surgical procedure from medical image data, the method comprising:
receiving an orthopaedic surgical plan request from a computing device of a healthcare facility via a network;
receiving a medical image of bony anatomy of a patient;
receiving constraint data corresponding to an orthopaedic surgical procedure to be performed upon the bony anatomy of the patient;
determining patient-specific anatomical data from the medical image of the bony anatomy of the patient;
determining whether the patient-specific anatomical data is at least one of outside of a reference range or exceeds a reference threshold;
determining whether the orthopaedic surgical procedure to be performed upon the bony anatomy of the patient is a difficult orthopaedic surgical procedure based on the received medical images and the received constraint data;
generating one of: (i) a first surgical plan for the orthopaedic surgical procedure to be performed upon the bony anatomy of the patient in response to determining that the orthopaedic procedure to be performed upon the bony anatomy the patient is not a difficult orthopaedic surgical procedure; or (ii) a second surgical plan, different from the first surgical plan, for the orthopaedic surgical procedure to be performed upon the bony anatomy of the patient in response to determining that the orthopaedic procedure to be performed upon the bony anatomy the patient is a difficult orthopaedic surgical procedure; and
transmitting at least one of the first or second surgical plans to the computing device of the healthcare facility via the network;
wherein determining whether the orthopaedic surgical procedure to be performed upon the bony anatomy of the patient is a difficult orthopaedic surgical procedure comprises determining whether the orthopaedic surgical procedure to be performed upon the bony anatomy of the patient is a difficult orthopaedic surgical procedure as a function of determining that the patient-specific anatomical data is at least one of outside of the reference range or exceeds the reference threshold.

2. The method of claim 1 , further comprising:
comparing the patient-specific anatomical data determined from the medical image of the bony anatomy of the patient to historical anatomical data; and
wherein determining whether the orthopaedic surgical procedure to be performed upon the bony anatomy of the patient is a difficult orthopaedic surgical procedure comprises determining whether the orthopaedic surgical procedure to be performed upon the bony anatomy of the patient is a difficult orthopaedic surgical procedure as a function of comparing the patient-specific anatomical data to historical anatomical data.

3. The method of claim 1 , further comprising:
comparing a degree of femoral rotation obtained from the patient-specific anatomical data determined from the medical image of the bony anatomy of the patient; and
wherein determining whether the patient-specific anatomical data determined from the medical image of the bony anatomy of the patient is at least one of outside of a reference range or exceeds a reference threshold comprises determining whether the degree of femoral rotation obtained from the patient-specific anatomical data exceeds a reference threshold degree of femoral rotation.

4. The method of claim 1 , further comprising:
comparing a tibial slope obtained from the patient-specific anatomical data determined from the medical image of the bony anatomy of the patient; and
wherein determining whether the patient-specific anatomical data determined from the medical image of the bony anatomy of the patient is at least one of outside of a reference range or exceeds a reference threshold comprises determining whether the tibial slope obtained from the patient-specific anatomical data exceeds a reference threshold tibial slope.

5. The method of claim 1 , further comprising:
determining whether a complexity exists as a function of the patient-specific anatomical data determined from the medical image of the bony anatomy of the patient; and
wherein determining whether the orthopaedic surgical procedure to be performed upon the bony anatomy of the patient is a difficult orthopaedic surgical procedure comprises determining whether the orthopaedic surgical procedure to be performed upon the bony anatomy of the patient is a difficult orthopaedic surgical procedure as a function of determining that a complexity exists.

6. The method of claim 5 , wherein determining whether a complexity exists as a function of the patient-specific anatomical data determined from the medical image of the bony anatomy of the patient comprises determining at least one of (i) whether pre-existing metal is present in a surgical area within which the orthopaedic surgical procedure is to be performed upon the bony anatomy of the patient as a function of the patient-specific anatomical data, or (ii) whether an anatomical deformation exists in the bony anatomy of the patient as a function of the patient-specific anatomical data.

7. The method of claim 1 , further comprising:
transmitting the received medical image and the constraint data corresponding to the orthopaedic surgical procedure to be performed upon the bony anatomy of the patient to a remote computing device via the network;
receiving a recommendation affecting the orthopaedic surgical procedure to be performed upon the bony anatomy of the patient from the remote computing device via the network; and
wherein generating the second surgical plan for the orthopaedic surgical procedure to be performed upon the bony anatomy of the patient comprise generating the second surgical plan for the orthopaedic surgical procedure to be performed upon the bony anatomy of the patient as a function of the recommendation received from the remote computing device.

8. The method of claim 1 , further comprising:
generating a notification in response to determining that the orthopaedic surgical procedure to be performed upon the bony anatomy of the patient is a difficult orthopaedic surgical procedure; and
transmitting the generated notification to the computing device of the healthcare facility.

9. The method of claim 1 , wherein receiving a medical image of bony anatomy of a patient comprises receiving at least one of a radiographic image, a magnetic resonance imaging image, a computerized tomography image, or a three dimensional ultrasound image.

10. The method of claim 1 , wherein the first and second surgical plans comprise at least one of (i) a plurality of ordered surgical steps and instructional images corresponding to the orthopaedic surgical procedure to be performed upon the bony anatomy of the patient; (ii) a recommended orthopaedic implant for use during the orthopaedic surgical procedure to be performed; (iii) an image comprising a digital template of the recommended orthopaedic implant superimposed onto the bony anatomy of the patient in the medical image; (iv) one or more recommended reusable instruments to use during the orthopaedic surgical procedure to be performed; (v) one or more recommended patient-specific instruments to use during the orthopaedic surgical procedure to be performed; (vi) one or more recommended single-use instruments to use during the orthopaedic surgical procedure to be performed; or (vii) one or more videos of surgical procedures performed on other patients having a similar bony anatomy.

11. The method of claim 1 , wherein receiving the orthopaedic surgical plan request from the computing device of the healthcare facility via the network comprises receiving the surgical plan request from a surgeon via the co
