Abstract
An orthopedic guide may include a cannulated shaft, a body and a plurality of arms. The body can be coupled to the cannulated shaft. The plurality of arms can extend radially outward from the body. One or more of the plurality of arms can include an outer radial end portion that has a length in a radial dimension configured to indicate a minimum safety boundary for a humeral implant relative to a cortex of a humerus.
Claims20
An orthopedic guide for a shoulder arthroplasty comprising:
- a cannulated shaft;
- a body coupled to the cannulated shaft;
- and
- a plurality of arms extending radially outward from the body, wherein one or more of the plurality of arms include an outer radial end portion that has a length in a radial direction relative to a centerline axis of the cannulated shaft, the length of the outer radial end portion configured to indicate a minimum safety boundary for a humeral implant relative to a cortex of a humerus.

An orthopedic system for a shoulder arthroplasty comprising:
- a humeral implant configured for fixation to a humerus, wherein the humeral implant has a body, a centerline axis, and a plurality of arms extending radially outward from the body, each of the plurality of arms has an outermost radial end at a first distance measured in a radial direction from a centerline axis of the humeral implant;
- and
- a guide configured to place the humeral implant at a respective proximal surface of the humerus, wherein the guide has a body, a centerline axis, and a plurality of arms extending radially outward from the body of the guide, wherein each of the plurality of arms of the guide has an outer radial end portion that extends radially outward from an outermost surface of a corresponding one of the plurality of arms of the guide and wherein a length of the outer radial end portion in a radial direction indicates a minimum safety boundary for the humeral implant relative to a cortex of a humerus.
An orthopedic guide for a shoulder arthroplasty comprising:
- a cannulated shaft;
- a body coupled to the cannulated shaft;
- and
- a plurality of arms extending radially outward from the body, wherein each of the plurality of arms has an outer radial end portion configured to indicate a minimum safety boundary for a humeral implant relative to a cortex of a humerus, wherein each outer radial end portion has a different length in a radial direction relative to a centerline axis of the cannulated shaft, the different length of each outer radial end portion based at least in part on a shape of the cortex including a depth of the cortex.
