Abstract

Implant guides, devices, systems and methods for implants to correct bone deformities and fractures in the lower extremity are disclosed. Specifically, implant guides, devices, systems and methods used for implants to correct bone deformities and/or fractures in the foot and ankle are disclosed.

Claims (82)

1 . An implant guide device, comprising:

a base;

a first arm coupled to a first end of the base, wherein the first arm comprises:

a retention mechanism;

one or more through holes associated with the retention mechanism, each through hole of the one or more through holes configured to engage an accessory; and

wherein the accessory facilitates inserting a fastener into a patient's lower extremity;

a second arm coupled to a second end of the base; and

a targeting arm hingedly coupled to the first arm at a first coupling point and the second arm at a second coupling point, wherein a first end of the targeting arm is directly coupled to the first arm, and wherein a second end of the targeting arm is directly coupled to the second arm.

2 . The implant guide device of claim 1 , wherein the base comprises:

an aperture configured to receive an implant, wherein the aperture is positioned near a midpoint between the first end and the second end of the base; and

wherein the implant includes a nail system to be inserted into a patient's lower extremity.

3 . The implant guide device of claim 2 , wherein the aperture is further configured to receive a portion of a mounting system, the mounting system being coupled to the implant.

4 . The implant guide device of claim 1 , wherein the targeting arm comprises:

a lock configured to fixate a position of the targeting arm.

5 . The implant guide device of claim 1 , wherein the targeting arm comprises:

one or more inlays configured to provide a visual trajectory of an accessory to be inserted into the implant guide device; and

wherein the one or more inlays are embedded in a crevice of a side support of the targeting arm.

6 . The implant guide device of claim 1 , wherein the targeting arm is configured to provide elevated support to a patient's lower extremity.

7 . The implant guide device of claim 1 , wherein the targeting arm comprises:

one or more orientation markings; and

wherein the one or more orientation markings are configured to align with one or more corresponding side support orientation markings, the side support orientation markings being located on at least one of the first arm and the second arm.

8 . The implant guide device of claim 1 , wherein the first arm extends perpendicularly away from the base, wherein the second arm extends perpendicularly away from the base, and wherein the first arm is positioned parallel to the second arm as the first arm and second arm extend away from the base.

9 . An implant guide system, comprising:

an implant guide device, comprising:

a base;

a first arm coupled to a first end of the base;

a second arm coupled to a second end of the base; and

a targeting arm hingedly coupled to the first arm at a first coupling point and the second arm at a second coupling point, wherein a first end of the targeting arm is directly coupled to the first arm, and wherein a second end of the targeting arm is directly coupled to the second arm, wherein the targeting arm comprises:

a lock configured to fixate a position of the targeting arm; and

one or more inlays configured to provide a visual trajectory of an accessory to be inserted into the implant guide device; and

wherein the one or more inlays are embedded in a crevice of a side support of the targeting arm;

a mounting system traversing an aperture of the base, wherein the aperture is positioned at a midpoint between the first end and the second end of the base; and

an implant coupled to the mounting system.

10 . The implant guide system of claim 9 , wherein the base comprises:

the aperture configured to receive the implant; and

wherein the implant includes a nail system to be inserted into a patient's lower extremity.

11 . The implant guide system of claim 10 , wherein the aperture is further configured to receive a portion of the mounting system, the mounting system being coupled to the implant.

12 . The implant guide system of claim 9 , wherein the first arm comprises:

a lock;

one or more through holes associated with the lock, wherein each through hole of the one or more through holes are configured to engage an accessory; and

wherein the accessory facilitates inserting a fastener into a patient's lower extremity.

13 . The implant guide system of claim 9 , wherein the targeting arm is configured to provide elevated support to a patient's lower extremity.

14 . The implant guide system of claim 9 , wherein the targeting arm comprises:

one or more orientation markings; and

wherein the one or more orientation markings are configured to align with one or more corresponding side support orientation markings, the side support orientation markings being located on at least one of the first arm and the second arm.

15 . The implant guide system of claim 9 , further comprising:

a targeting guide assembly;

wherein the targeting guide assembly comprises:

a guide arm;

a drill guide tube;

a guide pin;

an alignment fin; and

a drill pin.

16 . A surgical method, comprising:

selecting an implant guide system, the implant guide system comprising:

a base;

a first arm coupled to a first end of the base, wherein the first arm comprises:

a retention mechanism;

one or more through holes associated with the retention mechanism, each through hole of the one or more through holes configured to engage an accessory; and

wherein the accessory facilitates inserting a fastener into a patient's lower extremity;

a second arm coupled to a second end of the base; and

a targeting arm hingedly coupled to the first arm at a first coupling point and the second arm at a second coupling point, wherein a first end of the targeting arm is directly coupled to the first arm, and wherein a second end of the targeting arm is directly coupled to the second arm;

coupling an implant to a mounting system of the implant guide system;

positioning an implant guide device of the implant guide system for desired implant orientation;

inserting the implant into a lower extremity of a patient using the implant guide system;

inserting at least one fastener into the patient's lower extremity and through the implant using the implant guide system;

releasing the implant inside the lower extremity of the patient by removing the implant guide device and the mounting system;

inserting a tensioning fastener onto the implant; and

closing the patient's incisions.

17 . The surgical method of claim 16 , wherein the positioning an implant guide device of the implant guide system for desired implant orientation further comprises:

positioning a patient's lower extremity;

exposing the patient's tibiotalar joint;

exposing the patient's subtalar joint;

preparing the patient's ankle joint; and

fixating, temporarily, the patient's ankle.

18 . The surgical method of claim 17 , wherein the inserting the implant into a lower extremity of a patient using the implant guide system further comprises:

forming a canal in the patient's lower extremity; and

inserting the implant into the canal;

wherein the inserting the at least one fastener into the patient's lower extremity and through the implant using the implant guide system further comprises:

inserting a first fastener into the patient's tibia;

inserting a second fastener into the patient's calcaneus; and

inserting a third fastener into the patient's talocalcaneal joint.
