1. An orthopaedic implant comprising:
- a body defining at least one landmark, the body defining a longitudinal groove along an outer surface of the body, the longitudinal groove comprising a driving end portion and a non-driving end portion and having a length along the driving end portion and non-driving end portion, wherein the longitudinal groove is defined at least in part by side walls and a floor connecting the side walls;
a probe comprising a sensor, the sensor being spaced apart from the at least one landmark a set distance, the probe and sensor being releasably fixable to the body of the implant to limit movement of the sensor relative to the at least one landmark; and
wherein the body comprises multiple discrete receiving portions configured to releasably fix the probe to the body, the receiving portions being spaced apart along the length of the longitudinal groove, wherein each of the discrete receiving portions comprises a portion of one of the side walls that is shaped to press a section of the probe received in the receiving portion against the floor.

20. A method comprising:
-
releasably fixing a probe comprising a sensor to an orthopaedic implant such that (i) the sensor is spaced apart from at least one landmark defined in the orthopaedic implant a set distance, and (ii) discrete receiving portions spaced apart along a length of the orthopaedic implant releasably retain the probe in the orthopaedic implant; and after releasably fixing the probe to the orthopaedic implant, calibrating the sensor to determine a spatial relationship between the sensor and the at least one landmark. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27)

28. An intramedullary nail comprising:
-
a body defining at least one screw hole; a longitudinal groove with a driving end portion and a non-driving end portion formed along an outer surface of the body, wherein the longitudinal groove is defined at least in part by side walls and a floor connecting the side walls; and a probe comprising a sensor, the probe being releasably securable in the longitudinal groove such that the sensor is spaced apart from the at least one screw hole a set distance, wherein the body comprises discrete receiving portions that are configured to releasably secure the probe in the longitudinal groove, the receiving portions being located at intermittent locations along the longitudinal groove, wherein each of the discrete receiving portions comprises a structure that extends into or over a portion of the longitudinal groove to releasably secure a portion of the probe in the longitudinal groove, wherein each of the discrete receiving portions comprises a portion of one of the side walls that is shaped to press a section of the probe received in the receiving portion against the floor. - View Dependent Claims (29, 30, 31, 32, 33, 34)
