    摘要： An orthopedic device for a shoulder joint includes a patient-specific alignment guide. The alignment guide includes a cap having a three-dimensional engagement surface customized in a pre-operative plan by computer imaging to be complementary and closely mate and conform to a humeral head of a proximal humerus of a patient. The alignment guide includes a tubular element extending from the cap and defining a longitudinal guiding bore for guiding an alignment pin at a patient-specific position and orientation determined in the pre-operative plan, and an orientation feature on the cap. The orientation feature is designed to orient the cap relative to the humeral head when the orientation feature is aligned with a landmark of the proximal humerus.

    摘要： A medical device for preparing an elongated bone, such as a proximal femoral bone, for receiving an implant includes a patient-specific femoral guide and an elongated alignment element. The femoral guide has a patient-specific three-dimensional bone-engaging surface configured according to a preoperative plan based on a three-dimensional image model of the femoral bone to mate complementarily with the surface of the proximal femoral bone extending between the greater trochanter, the femoral neck and the femoral shaft of the proximal femur. The femoral guide includes a first guide end forming a planar guide configured for guiding a neck resection. The alignment member can be removably attached to the femoral guide and defines a reference axis for guiding a cutting tool into the femoral bone through a resected surface of the femoral neck.

    摘要： An instrument set and related method for preparing a proximal tibia during a bi-cruciate retaining procedure are disclosed. The instrument set can include a tibial resection block, a cut guide, and a locking arm. The tibial resection block can be configured to be fixed to an anterior portion of the proximal tibia. The tibial resection block can define a slot that extends in a medial-lateral direction when the tibial resection block is fixed to the proximal tibia. The cut guide can have a body, a medial arm, and a lateral arm. A medial cut slot can be defined between the body and the medial arm. A lateral cut slot can be defined between the body and the lateral arm. The cut guide can further comprise a tongue extending therefrom. The tongue can be configured to be received by and slidably translate along the slot of the tibial resection block.

    摘要： A tibial prosthesis assembly can comprise a tibial tray and a tibial insert. The tibial tray can have an inferior bone engaging surface, a superior surface, and a first retaining feature. The tibial insert can have an inferior tray engaging surface, a superior bearing surface, and a second retaining feature. The first and second retaining features can cooperate to inhibit substantial lift-off of the tibial insert away from the superior surface of the tibial tray while permitting a predetermined amount of rotation of the tibial insert around the superior surface in an assembled position.
