Abstract

Claims (35)

1 . A patient-specific surgical guide comprising:

a body comprising:

a metallic material;

a front surface;

a conformal tissue engaging surface opposite the front surface and contoured to a patient's anatomy; and

an opening extending through the body between the conformal tissue engaging surface and the front surface and sized to receive a surgical tool for preparing a portion of the patient's anatomy, wherein the conformal tissue engaging surface comprises one or more porous structure regions and at least one of the one or more porous structure regions has an effective radius of 0.5 mm to 1 mm.

2 . The patient-specific surgical guide of claim 1 , wherein the one or more porous structure regions comprise a gyroid structure.

3 . The patient-specific surgical guide of claim 1 , wherein:

the body comprises a first end, a second end, a first side, and a second side; and

the first end, the second end, the first side, and the second side are contoured not to engage at least one soft tissue structure of the patient's anatomy.

4 . The patient-specific surgical guide of claim 1 , wherein the conformal tissue engaging surface is a conformal bone engaging surface.

5 . A patient-specific surgical guide comprising:

a body comprising:

a metallic material;

a front surface;

a conformal tissue engaging surface opposite the front surface and contoured to a patient's anatomy, wherein the conformal tissue engaging surface comprises one or more textured regions and at least one of the one or more textured regions has a minimum feature size of 0.1 mm to 2 mm; and

an opening extending through the body between the conformal tissue engaging surface and the front surface.

6 . The patient-specific surgical guide of claim 5 , wherein the one or more textured regions comprise a porous structure.

7 . The patient-specific surgical guide of claim 5 , wherein:

the body comprises a first end, a second end, a first side, and a second side; and

the first end, the second end, the first side, and the second side are contoured to avoid at least one soft tissue structure of the patient's anatomy.

8 . The patient-specific surgical guide of claim 5 , wherein the body is a 3D-printed body.

9 . A system for performing a surgical procedure, the system comprising:

a patient-specific surgical guide comprising:

a metallic material;

a front surface opposite a conformal tissue engaging surface, wherein:

the conformal tissue engaging surface is contoured to patient anatomy and comprises one or more textured regions; and

at least one of the one or more textured regions has a minimum feature size of 0.1 mm to 2 mm; and

an opening extending through the patient-specific surgical guide between the conformal tissue engaging surface and the front surface and sized to receive a surgical tool; and

an implant.

10 . The system of claim 9 , wherein the implant is a patient-specific implant.

11 . The system of claim 9 , wherein the implant is an ankle implant.

12 . The system of claim 9 , wherein the implant is a shoulder implant.

13 . The system of claim 9 , wherein the implant is a hip implant.

14 . The system of claim 9 , wherein the implant is a knee implant.
