    摘要: A patient-specific alignment guide for an orthopedic implant. The alignment guide can include a body having first and second opposing surfaces, the second surface adapted for positioning over a skin surface, and at least one extension extending from the second surface body. The extension has a distal end defining a patient-specific end surface that is mateable in form-fitting manner with a subcutaneous portion of the patient's anatomy, and at least one guiding passage extending between the first surface of the body and the distal end of the extension.

    摘要: A tibial component for use with a resected tibia can include a medial tray portion adapted to engage a portion of the resected tibia and a lateral tray portion adapted to engage a portion of the resected tibia. A linkage can couple the medial tray portion to the lateral tray portion such that at least one of the medial tray portion and the lateral tray portion is pivotable relative to the other of the medial tray portion and the lateral tray portion to position the medial tray portion and the lateral tray portion at separate angles with respect to each other.

    摘要: Solid-state deformation processing of crosslinked high molecular weight polymers such as UHMWPE, for example by extrusion below the melt transition, produces materials with a desirable combination of physical and chemical properties. Crosslinked bulk materials are heated to a compression deformable temperature, and pressure is applied to change a transverse dimension of the material. After cooling and stress relieving, a treated bulk material is obtained that has enhanced tensile strength in the axial direction orthogonal to the dimension change. In preferred embodiments, medical implant bearing materials are machined from the treated bulk material with the in vivo load bearing axis substantially parallel or coincident with the axial direction of the treated bulk material.

    摘要: A guide for cutting a bone comprising an anterior portion and a distal portion orientated at about a right angle to the anterior portion. The distal portion includes a guiding side, a distal surface at the guiding side, a box-cut shaped opening defined by the guiding side, a plurality of first cutting surfaces disposed at the guiding side at an acute angle relative to the distal surface of the guiding side operable to guide a cutting device to the bone to form chamfer cuts in the bone, and a second cutting surface disposed at the guiding side at least about a right angle to the distal surface operable to guide a cutting device to the bone to form a posterior cut in the bone.

    摘要: A system for cooperating with an elongated IM member during preparation of a bone for receiving a prosthesis can include a scaffold, skeleton or frame. An alignment assembly can be selectively coupled to the frame. The alignment assembly can cooperate with the IM member to position the frame relative to the bone. A cutting block can be selectively coupled to the frame. According to other features, a posterior stabilized (PS) box guide assembly can have a PS box guide attachment portion that selectively couples with the first attachment portion of the frame. A posterior foot can selectively couple with a second attachment portion on the frame. The posterior foot can be positioned to occupy space of a joint line in an installed position.
