Abstract

Claims (38)

1 . A bone tunnel guide for forming a bone tunnel in bone of a patient for a soft tissue transfer procedure, the bone tunnel guide comprising:

a body having a superior side, an inferior side, a medial side, a lateral side, a posterior side, and an anterior side;

a trajectory port that extends through the body, the trajectory port configured to guide a tool for forming the bone tunnel in a bone of a patient, the bone tunnel configured to receive soft tissue during the soft tissue transfer procedure, the trajectory port defined at least partially based on a bone model of at least a portion of the bone, the bone model based on medical imaging of the bone of the patient; and

a bone engagement feature that extends from the body, the bone engagement feature configured to engage at least a portion of the bone such that the bone engagement feature positions the bone tunnel guide in a position that corresponds to a modeled position of a bone tunnel guide model engaging a bone model.

2 . The bone tunnel guide of claim 1 , wherein at least one aspect of the bone tunnel guide is configured based at least partially on user instructions provided before the bone tunnel guide is fabricated.

3 . The bone tunnel guide of claim 1 , wherein the bone engagement feature comprises at least one patient-specific aspect unique to the patient.

4 . The bone tunnel guide of claim 3 , wherein the at least one patient-specific aspect comprises a bone engagement surface on a bone-facing surface of the bone engagement feature, the bone engagement surface configured to engage at least one landmark of the bone.

5 . The bone tunnel guide of claim 4 , wherein the bone engagement surface corresponds to a surface of the bone such that the bone tunnel guide provides haptic feedback to a user when the bone tunnel guide translates to the position corresponding to the modeled position of the bone tunnel guide model engaging the bone model.

6 . The bone tunnel guide of claim 1 , further comprising a plurality of bone engagement features, each extending away from the trajectory port.

7 . The bone tunnel guide of claim 6 , wherein a number of bone engagement features of the plurality of bone engagement features is directly proportional to a number of landmark configurations near, or at, the modeled position of the bone tunnel guide model engaging the bone model.

8 . The bone tunnel guide of claim 6 , wherein a number of bone engagement features of the plurality of bone engagement features is determined at least partially by user directions.

9 . The bone tunnel guide of claim 1 , further comprising:

a handle configured to secure the bone tunnel guide in place for formation of a bone tunnel by way of the trajectory port.

10 . The bone tunnel guide of claim 9 , wherein the handle comprises a shaft having a proximal end and a distal end, the distal end comprising a coupler comprising external threads configured to engage internal threads formed in the body.

11 . The bone tunnel guide of claim 1 , wherein the trajectory port comprises a port body that extends away from the body, the port body having a length that enables a user to grasp the port body to secure the bone tunnel guide in place for formation of a bone tunnel by way of the trajectory port.

12 . The bone tunnel guide of claim 1 , further comprising a bone engagement surface on at least part of the inferior side of the body, the bone engagement surface defined at least partially based on the bone model.

13 . The bone tunnel guide of claim 1 , further comprising a landmark registration feature configured to engage a landmark of the bone.

14 . The bone tunnel guide of claim 1 , wherein a configuration of the bone engagement feature is directly proportional to a landmark configuration of the bone indicated on the bone model.

15 . The bone tunnel guide of claim 1 , wherein the bone tunnel guide is fabricated from one of a polymer and metal.

16 . A tendon transfer system for tendon deployment to remediate a bone condition present in a patient's foot, comprising:

a tendon trajectory guide comprising:

a body having a superior side, an inferior side, a medial side, a lateral side,

a posterior side, and an anterior side;

a trajectory port that extends through the body, the trajectory port configured to guide a tool for forming a bone tunnel in a foot bone of a patient, the trajectory port defined at least partially on a bone model of at least a portion of the foot bone, the bone model based on medical imaging of the foot bone of the patient; and

a bone engagement surface on the inferior side of the body, the bone engagement surface configured to engage a surface of the foot bone such that the bone engagement surface positions the tendon trajectory guide at a desired position on the foot bone;

an inserter having:

a proximal end;

a distal end;

an elongated body between the proximal end and the distal end; and

wherein the distal end comprises a point and the proximal end comprises an opening; and

a handle comprising a first coupler configured to removably engage with a second coupler connected to the tendon trajectory guide.

17 . The tendon transfer system of claim 16 , further comprising a plurality of appendages that extend laterally from the body, each appendage having an appendage inferior surface and comprising a bone engagement surface on the appendage inferior surface.

18 . A bone tunnel guide for forming a bone tunnel in a bone of a patient for a soft tissue transfer procedure, the bone tunnel guide comprising:

a body having a superior side, an inferior side, a medial side, a lateral side, a posterior side, and an anterior side;

a trajectory port that extends through the body, the trajectory port configured to guide a tool for forming a bone tunnel in a bone of a patient, the bone tunnel configured to receive soft tissue during the soft tissue transfer procedure, the trajectory port defined at least partially based on a bone model of at least a portion of the bone, the bone model based on medical imaging of the bone of the patient; and

a plurality of bone engagement features that extend from the body, the plurality of bone engagement features configured to engage at least a portion of the bone and wherein a number of bone engagement features is defined at least in part by user instructions.

19 . The bone tunnel guide of claim 18 , wherein the bone tunnel guide comprises at least one patient-specific aspect unique to the patient.

20 . The bone tunnel guide of claim 19 , wherein the patient-specific aspect comprises at least one bone engagement surface on a bone-facing surface of at least one of the plurality of bone engagement features, the at least one bone engagement surface configured to engage at least one landmark of the bone of the patient.
