Abstract: A method of performing joint arthroplasty includes accessing a surface on a bone and supporting a stop with the accessed surface. The method includes positioning an instrument at least partially within the stop, the instrument having a body and a punch, the punch including a portion thereof having a shape similar to a shape of a stem of an implant, and rotating the stop with respect to the accessed surface based upon an indicia on one of the body and the stop so as to position the punch rotationally with respect to the accessed surface at a first orientation. The method further includes moving the body axially with respect to the stop to form a cavity in the bone with the punch at the first rotational orientation, the formed cavity having a shape similar to the stem of the implant, and implanting the stem of the implant into the cavity.

Abstract: A kit for use in performing joint arthroplasty on a head of a long bone is disclosed. The kit includes: a first implant including a first implant articulating surface and an opposed first implant mounting surface having a first implant location feature; and an instrument for preparing a cavity in the head of the long bone. The instrument includes a body and a punch extending from the body. The punch includes a portion thereof having a shape similar to the first implant location surface of the implant. A method for providing joint arthroplasty is also disclosed.

Abstract: A stemless humeral component for replacing the humeral head of a patient's humerus includes a support flange having a number of cantilevered legs extending distally away from a bottom surface thereof. Instruments and methods for surgically installing the stemless humeral component are also disclosed.

Abstract: A prosthesis assembly for use with a scapula in one embodiment includes an acromion spacer unit, a first articulation surface on an inferior surface of the acromion spacer unit, a bone contacting surface on a superior surface of the acromion spacer unit, and a bone mounting member extending sideways from the acromion spacer unit and oriented such that when the acromion spacer unit is mounted on a scapula, the acromion spacer unit is positioned at a height above the height of a midpoint of a glenoid fossa of the scapula.

Abstract: A humeral prosthesis includes a first body having a first body articulating surface defining a generally circular outer periphery, and a first centerline axis. The first body having a support surface opposite to the first body articulating surface, the first body is hollow and configured to receive a head of the humerus, and a stem extending away from the support surface, the stem defining a second centerline axis which is coincident with the first centerline axis. The prosthesis further includes a second body in the form of a flange which extends laterally from a portion of the circular outer periphery, the first body articulating surface and a surface of the second body defining a boundary portion between them which is generally smooth and continuous, wherein the second body is located superiorly and the surface of the second body which bounds the first body articulating surface is a second articulating surface.

Abstract: A kit for making a glenoid prosthesis is provided. The kit includes an articulating member having an articulation side and an opposing second side opposing the articulating side, in which the opposing second side includes a locking mechanism. The kit also includes a plurality of bases. Each of the plurality of bases has an articulating member facing side and a glenoid attachment side, in which each of the plurality of glenoid attachment sides includes at least one glenoid attachment member extending outwardly and sized and shaped to extend into a patient's glenoid. The glenoid attachment member of one of the plurality of bases differs from the glenoid attachment member of at least one other of the plurality of bases, and in which each of the plurality of bases includes a locking mechanism sized and shaped to lock each of the plurality of bases to the articulating member.

Abstract: A method of assembling a glenoid assembly. The method includes selecting a base from a plurality of bases. At least one of the plurality of bases has a size different than a size of one of the other of the plurality of bases. The selected base is coupled to an articulating member and the selected base is locked to the articulating member via a locking mechanism.
