摘要： A knee replacement prosthesis includes a distal femoral implant, including a femoral head portion, including an outer arcuate surface, and interior posterior surface, an interior distal surface disposed at a first angle with respect to the interior posterior surface, and a first interior intermediate surface joining the interior posterior surface and the interior distal surface and being disposed at a second angle with respect to the interior posterior surface and at a third angle with respect to the interior distal surface. The distal femoral implant includes stackable femoral spacers secured to at least one of the interior posterior surface and the interior distal surface, thereby adjusting an aggregate spacing between the interior posterior surface and/or the interior distal surface and a resected surface of a distal femur of the patient. A tibial implant is also provided. Related methods of use of either implant or both are also provided.

摘要： A humeral implant is provided. The implant includes a humeral stem including a plurality of fins. At least one fin comprises a serrated bottom edge. A radial distance between an inner bottom edge of the at least one fin and a centerline of the humeral implant increases along a distal length of extension of the at least one fin. At least the serrated bottom edge of the at least one fin is configured to cut into and compact bone of the metaphysis of a humerus toward relatively denser cancellous bone of a peripheral portion of the humerus when press-fit therein, thereby providing sufficient press-fitting for cementless fixation of the humeral stem into the humerus. Related kits and methods are also provided.

摘要： A method of utilizing a distractor in a joint replacement procedure is provided. The method includes releasably engaging a datum to a datum securement of the distractor and gripping a handle of the distractor in an insertion position. The handle includes a first handle portion and a second handle portion. The method includes disposing a paddle of a tissue engaging portion of the distractor against a tissue surface and adjusting the handle from the insertion position to the distraction position to thereby independently move the paddle with respect to both the second handle portion and the first handle portion such that the paddle remains at a generally constant angle against the tissue surface as the tissue surface is distracted. The paddle is attached directly and exclusively to a distal tip of the second handle portion such that the paddle pivots about an axis transverse to a length of the handle.

摘要： Retractor holding frames and related methods are provided. The frame includes a support body including a first bore extending transversely from a first side of the support body to a second side of the support body opposite the first side, and a second bore extending transversely from the second side to the first side. The frame includes a left support frame arm including a first annular hub configured to be disposed within the first bore and a first plurality of posts disposed along an outer edge of the left support frame arm configured to retain a first retractor in a first orientation. The frame includes a right support frame arm including a second annular hub configured to be disposed within the second bore and a second plurality of posts disposed along an outer edge of the right support frame arm configured to retain a second retractor in a second orientation.

摘要： A modular augment cone system and methods of implanting the modular augment cone system. The system includes a main body cone a first cutout in the cone wall, and including a proximal end, a distal end, and a cone wall extending between the proximal and distal ends. A portion of the cone wall proximal to the first cutout includes an attachment feature. A first augment cone is positionable in the first cutout, the first augment cone including an attachment feature configured to mate with the attachment feature of the cone wall to attach the first augment cone into the first cutout. The main body cone can include a second cutout in the cone wall. In such systems, the modular augment cone system can include a second augment cone configured to mate with an attachment feature of the cone wall to attach the second augment cone into the second cutout.

摘要： An elbow prosthesis includes a capitellar implant having an articulating head and a stem. The articulating head includes a first passage along a first axis, a second passage along a second axis, and a receiving groove. The stem includes a proximal end and a connecting end. The connecting end includes a curved body having a bore. The curved body selectively mates with the receiving groove such that the bore axially aligns with the first axis of the first passage in an assembled position for collectively receiving a securing member. The second axis is located between the first axis and the proximal end of the stem

摘要： Disclosed is a tapered femoral hip stem implant for use in total hip replacement surgery. The implant is constructed using anthropomorphic data to obtain an optimal configuration for use in hip replacement surgery as well as to promote bone regrowth in the anterior proximal dimensions. In certain aspects, the implant is particularly well suited for use in an anterior approach to total hip replacement surgery due to its relatively small stem length. The implant includes a 12 degree proximal taper, which affords inherent fixation and rotational stability and a 4 degree distal taper to reduce the possibility of stress shielding.
