Orthopaedic transfer guides and methods of repair
This disclosure relates to planning systems, assemblies and methods. The planning systems, assemblies and methods disclosed herein may be utilized for planning and implementing orthopaedic procedures to restore functionality to a joint, and may include one or more transfer members for positioning implants and other surgical devices relative to patient anatomy.
1 . A transfer guide for an orthopaedic procedure comprising:
a guide body including an interface portion configured to be securable to a surgical device, wherein the surgical device includes an implant securable to bone;
a flange extending radially from the guide body relative to a guide axis of the guide body; and
at least one transfer member coupled to the guide body, the at least one transfer member including a carrier and an outrigger extending from the carrier, the carrier rotatable about a periphery of the guide body to set a circumferential position of the outrigger relative to the guide axis, the outrigger configured to contact tissue to set an orientation of the guide body, and the outrigger is configured to set an orientation of the surgical device securable to the interface portion;
wherein one of the flange and the carrier includes an indicator, and another one of the flange and the carrier includes a ruler;
wherein the indicator is moveable relative to the ruler to indicate the circumferential position of the outrigger relative to the guide axis of the guide body; and
wherein a first portion of the carrier extends from the guide body radially beyond the flange relative to the guide axis, and the outrigger extends distally from the first portion of the carrier at a position radially outward of a periphery of the flange relative to the guide axis.
2 . The transfer guide as recited in claim 1 , wherein:
the guide body includes an elongated guide shaft extending along the guide axis between a proximal end and a distal end; and
the interface portion is established adjacent the distal end of the guide shaft.
3 . The transfer guide as recited in claim 2 , further comprising:
the implant; and
wherein the interface portion is adapted to limit relative rotation between the guide shaft and the implant with respect to the guide axis.
4 . The transfer guide as recited in claim 3 , wherein:
the interface portion includes an inserter adjacent to the distal end of the guide shaft;
the inserter includes a plurality of protrusions distributed about the guide axis; and
the protrusions are adapted to mate with an array of insertion apertures of the implant to limit relative rotation between the guide shaft and the implant with respect to the guide axis.
5 . The transfer guide as recited in claim 3 , wherein:
the transfer guide and the implant are rotatable together as a unit in a first rotational direction about an implant axis of the implant.
6 . The transfer guide as recited in claim 3 , wherein:
the indicator and the ruler cooperate to establish a protractor;
the ruler includes indicia associated with circumferential positions of the outrigger relative to the guide axis; and
the indicator is moveable in a second rotational direction relative to the ruler in response to rotation of the carrier about the periphery of the guide body to indicate the circumferential position of the outrigger relative to the guide axis of the guide body.
7 . The transfer guide as recited in claim 1 , wherein:
the carrier includes at least one aperture; and
the outrigger is slidably received in the at least one aperture to set a position of the outrigger relative to the guide body.
8 . The transfer guide as recited in claim 7 , wherein:
the at least one aperture includes a plurality of apertures distributed in a radial direction and/or circumferential direction relative to the guide axis of the guide body; and
the outrigger is insertable in a selectable one of the plurality of apertures to set a position of the outrigger relative to the guide axis.
9 . The transfer guide as recited in claim 8 , wherein:
the at least one transfer member includes a set of transfer members releasably securable to the guide body; and
the set of transfer members are dimensioned such that a distribution of the plurality of apertures differs for each transfer member of the set of transfer members.
10 . The transfer guide as recited in claim 1 , wherein:
the guide body is dimensioned to contact an articular surface and/or a non-articular surface of a bone.
11 . A kit for an orthopaedic procedure comprising:
at least one implant including a baseplate, the baseplate including a main body and an anchor member extending outwardly from the main body, the anchor member securable to bone; and
the transfer guide according to claim 1 , wherein:
the interface portion is securable to the main body of the baseplate; and
wherein the outrigger extends from the carrier such that the outrigger is spaced apart from a periphery of the at least one implant.
12 . The kit as recited in claim 11 , wherein the baseplate includes a plurality of peripheral apertures distributed about an axis of the main body, and the outrigger is configured to set a position of the peripheral apertures in response to contact with tissue.
13 . The kit as recited in claim 11 , wherein the at least one implant includes an articulation member securable to the baseplate, and the articulation member includes an articulation surface configured to engage an articular surface of an opposed bone or implant.
14 . The kit as recited in claim 11 , wherein:
the at least one transfer member includes a set of transfer members releasably securable to the guide body, and the carrier of each transfer member of the set of transfer members includes a plurality of apertures;
the outrigger is insertable in a selectable one of the plurality of apertures to set a position of the outrigger relative to the guide axis of the guide body; and
the set of transfer members are dimensioned such that a distribution of the plurality of apertures differs for each transfer member of the set of transfer members.
15 . A method of performing an orthopaedic procedure comprising:
providing the transfer guide as recited in claim 1 ;
configuring the transfer guide, wherein the guide body extends along the guide axis, and the configuring step includes moving the carrier relative to the periphery of the guide body to set the orientation of the outrigger relative to the guide axis; and
positioning the transfer guide, including establishing contact between the outrigger and tissue to set the orientation of the transfer guide relative to a bone.
16 . The method as recited in claim 15 , wherein the configuring step includes moving the transfer member between a first position and a second position relative to the guide body based on at least one parameter of a preoperative plan.
17 . The method as recited in claim 15 , further comprising:
coupling the transfer guide and an implant to each other; and
positioning the implant in contact with the bone, including orienting the implant relative to the bone based on the orientation of the transfer guide.
18 . The method as recited in claim 15 , wherein the bone is a portion of a glenoid.
