Abstract

An orthopedic guide that can comprise a base, a first attachment and a second attachment is disclosed. The base can have a plurality of connection features spaced from one another along a longitudinal extent. The base can be configured to seat on a rim of a bone. The first attachment can be selectively coupled to the base at a first end portion thereof and can be selectively coupled to the base at a second end portion thereof. The first attachment can be arch shaped when coupled to the base. The first attachment can define a first plurality of apertures. The second attachment can be selectively coupled to the base at a first end portion thereof and can be selectively coupled to the base at a second end portion thereof. The second attachment can be arch shaped when coupled to the base. The first attachment can define a second plurality of apertures.

First claim

The claimed invention is:

1. An orthopedic system comprising:
a base having a plurality of connection features spaced from one another along a longitudinal extent, wherein the base is configured to be flexible to be bent in an arcuate shape to couple a first end portion with a longitudinally opposing second end portion;
a first attachment configured to selectively couple to a first one of the plurality of connection features at a first end portion thereof and configured to selectively couple to a second one of the plurality of connection features at a second end portion thereof, wherein the first attachment defines a first plurality of apertures; and
a second attachment configured to selectively couple to a third one of the plurality of connection features at a first end portion thereof and configured to selectively couple to a fourth one of the plurality of connection features at a second end portion thereof, wherein the second attachment defines a second plurality of apertures;
wherein the base includes indicia corresponding to the plurality of connection features, wherein a first plurality of the indicia are indicative of an inclination of the first attachment, and wherein a second plurality of the indicia are indicative of an anteversion of the second attachment.

2. The orthopedic system of claim 1 , wherein the first and second attachment are arch shaped when coupled to the base, and wherein the first attachment and second attachment are configured to be selectively moveable relative to one another along the base to align one of the first plurality of apertures of the first attachment with one of the second plurality of apertures of the second attachment.

3. The orthopedic system of claim 1 , wherein when the first end portion of the base is coupled to the second end portion of the base, a first longitudinal end of the base overlaps a second longitudinal end of the base.

4. The orthopedic system of claim 1 , wherein the base has a one or more second connection features configured to couple with at least one of the plurality of the connection features to couple the first end portion to the second end portion.

5. The orthopedic system of claim 4 , wherein the plurality of the connection features are located on at least a first side of the base and the one or more second connection features are located on a second side opposing the first side of the base.

6. An orthopedic system comprising:
a base having a plurality of connection features spaced from one another along a longitudinal extent, wherein the base is configured to be flexible to be bent in an arcuate shape to couple a first end portion with a longitudinally opposing second end portion;
a first attachment configured to selectively couple to a first one of the plurality of connection features at a first end portion thereof and configured to selectively couple to a second one of the plurality of connection features at a second end portion thereof, wherein the first attachment defines a first plurality of apertures;
a second attachment configured to selectively couple to a third one of the plurality of connection features at a first end portion thereof and configured to selectively couple to a fourth one of the plurality of connection features at a second end portion thereof, wherein the second attachment defines a second plurality of apertures;
a computer including at least one processor and a memory device, the memory device including instructions that, when executed by the at least one processor, cause the computer to:
access image data of a target location including a bone of a patient, the image data including at least one of a size of the bone, an orientation of the bone and a shape of the bone;
display based upon the collected image data one or more patient-specific characteristics of the bone;
determine an anteversion and an inclination for an acetabular implant based at least in part upon the one or more patient-specific characteristics of the bone; and
convert the one or more patient-specific characteristics of the anatomy of the patient to a first setting to position the first attachment relative to the base and a second setting to position the second attachment relative to the base.

7. The orthopedic system of claim 6 , further comprising instructions that cause the computer to convert the one or more patient-specific characteristics of the anatomy of the patient to a third setting to determine a size of the base.

8. The orthopedic system of claim 6 , wherein the first setting and the second setting each correspond to one of the plurality of connection features and comprise a first and a second of a plurality of standard settings for the first attachment and the second attachment, respectively, and the first setting and the second setting are selected as a best match to the one or more patient-specific characteristics of the bone.
