    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.

    摘要: Various method and apparatuses may be used to perform a procedure, such as a resection of a portion of the anatomy for preparation of the implants of a prosthetic. Various resecting member, including saw blades having selected geometries and shapes, can be used to assist in the resection of an anatomy to provide for implantation of a prosthetic. In addition, a cutting block assembly may be used to guide the resecting member. The cutting block assembly may be moveably mounted relative to the portion to be resected.

    摘要: A method for preparing surgical kits for use during a surgery includes preparing a pre-operative surgical plan for a patient and selecting a set of surgical instruments based on the pre-operative surgical plan. The set of surgical instruments includes at least a general instrument, a first size-specific instrument, a patient-specific instrument, and a surgeon-specific instrument. The general instrument is selected from a predetermined group of off-the-shelf instruments. The first size-specific instrument has a first size selected from predetermined sizes. The patient-specific instrument includes a three-dimensional contoured engagement surface configured to nest into a portion of a native anatomy in a single location. The surgeon-specific instrument is selected based on a surgeon preference and is a different instrument than the selected general instrument, first size-specific instrument, and patient-specific instrument. The method further includes preparing a surgeon instrument kit containing the set of surgical instruments in sterilized form.
