    • An apparatus and method for preparing a bone for receiving a prosthetic implant (74) having a body portion (75) including a plurality of fins (78, 80, 82) arranged in a predetermined pattern and a stem portion (76). The apparatus comprises a cutter (12) for cutting fin tracks in the bone (70) to guide the plurality of fins (78, 80, 82) on the implant (74) as the implant (74) is installed into the bone (70). The apparatus also includes a rod (14) coupled to the cutter (12) for locating the cutter (12) relative to an intramedullary canal of the bone (70), and a drive rod (18) and head (20) coupled to the cutter (12) for driving the cutter (12) and rod (14) into the bone (70). The rod (14) is preferably removable from the cutter (12) to permit a rod having a different size to be selectively coupled to the cutter (12) depending upon the selected size of the stem (76) of the implant (74). The apparatus also includes a collar (16) slidably coupled to the cutter (12) in a predetermined orientation. The collar (16) is configured to engage the bone (70) to determine a proper rotational position of the cutter (12) relative to the bone (70) about a longitudinal axis of the rod (14).

    • An orthopedic device includes a drill guide configured to be mounted on a patient-specific alignment guide for intraoperatively confirming alignment of the patient-specific alignment guide relative to a bone. The patient-specific alignment guide includes first and second referencing holes. The drill guide includes a main body with a first coupling member and a second coupling member. The first and second coupling members are configured to be received within the first and second referencing holes, respectively. The first and second coupling members each include corresponding first and second drill openings configured to align with the first and second referencing holes, respectively. The drill openings each guide a drilling tool toward the bone to drill corresponding holes in the bone. The main body also includes an alignment confirmation feature configured for confirming alignment of the patient-specific alignment guide relative to the bone before drilling holes in the bone.
    • 整形外科装置包括钻引导件,其构造成安装在患者特异的对准引导件上,用于在手术中确认患者特异性对准引导件相对于骨骼的对准。 患者专用对准引导件包括第一和第二参考孔。 钻子引导器包括具有第一联接构件和第二联接构件的主体。 第一和第二联接构件分别被配置为容纳在第一参考孔和第二参考孔内。 第一和第二联接构件各自包括被配置为分别与第一和第二参考孔对准的对应的第一和第二钻孔。 钻孔开口每个引导钻孔工具朝向骨头以在骨中钻取相应的孔。 主体还包括对准确认特征,其配置用于在钻孔之前确认患者特异性对准引导件相对于骨骼的对准。
