A trial medical instrument for aligning an acetabular component, comprising: a first portion configured to fit within a patient's acetabulum; and a second portion extending from the first portion; wherein the second portion extends from the first portion in a direction that mimics a shape formed by a femoral implant component coupled with an acetabular implant component when a femur to which the femoral implant component is coupled is in a position relative to an acetabulum to which the acetabular implant component is coupled that is near an extent of a typical range of motion of the femur. As used herein, the phrase 'extent of a typical range of motion' describes typical angular displacements of a femur as usually limited by patient anatomy.

Acetabular implant alignment devices and methods

Patient-matched surgical instruments and associated methods having an anatomy facing side including several discrete, physically separate anatomy contacting portions configured to match the anatomy of a particular patient and including one or more of non-uniform in distribution, non-uniform in shape and non-uniform in surface area.

Patient-matched instruments

Patient-matched surgical instruments, and methods for making patient-matched surgical instruments, may include patient-matched surgical instruments having an anatomy facing side with several discrete, physically separate anatomy contacting portions configured to match the anatomy of a particular patient. The anatomy contacting portions may be one or more of non-uniform in distribution, non-uniform in shape or non-uniform in surface area.

Systems and methods utilizing patient-matched instruments

A length-adjustable IM nail system includes a telescoping IM nail with proximal and distal bodies. An inner magnet within the proximal body is connected to a threaded rod which, in turn, is connected to the distal body. The threaded rod passes through a threaded block which is connected to the proximal body. The position of the distal end of the threaded rod is fixed with respect to the distal body, but may rotate freely within this fixed position. An actuator is also disclosed that includes a pair of rotating magnets disposed in an angular relationship with each other and the axis of the IM nail and the patient's limb. Rotation of these outer magnets in the same direction results in rotation of the inner magnet and threaded rod and a telescoping axial movement of the threaded block and proximal body with respect to the distal body.

Telescoping IM nail and actuating mechanism

Orthopedic implants which include the components of zirconium or zirconium-based alloys having surfaces coated with oxidized zirconium or alternatively, other orthopedic implants comprising abrasion resistant surfaces contacting surfaces of cross-linked polyethylene are disclosed. Such implants provide low friction, highly wear resistant coatings especially useful in artificial joints, such as hip joints, knee joints, elbows, etc., but also useful in other implant devices as well. The implants also find use as vertebral disc prostheses.

A mobile bearing knee prosthesis enables a surgeon to convert a mobile bearing insert having articular surfaces, supported by a tibial base plate or tray from a rotating and translating prosthesis to one that rotates only. This conversion is accomplished with a fastener or locking member that connects through an opening in the insert to the tibial base plate. This prosthesis can be used as part of a total knee surgery when the surgeon chooses to use a prosthesis that incorporates a movable articular surface. In one embodiment, a projecting portion extends proximally from the insert and cooperates with a cam on the femoral component. The projecting portion can be a post extending up from the proximal surface of the insert and the femoral component includes an intercondylar surface that may contact the post to constrain the relative motion between the femoral component and the insert. In another embodiment, the insert is a two part assembly that includes a larger member with a central opening and a smaller member that fits the opening.

A joint fixator apparatus conforms to the natural axis of rotation of the joint in question, such as a patient's wrist or knee to avoid the possibility of bone fragment displacement and/or fracture reduction. The apparatus includes two fixation rod sections or shaft sections with a spring module therebetween. The spring module is in the form of a flexible coupler that connects to respective ends of the external fixator rod. The module can include a removable clip to restrain the motion of the spring a desired amount such as before healing takes place. The rods can be used to hold pin clamps which then hold bone pins for attachment to selected bones of the patient such as above and below a joint or above and below a fracture. The pin clamps can be moved along the rod sections to provide distraction of the joints for a ligamentotaxis effect in reducing the fracture.

An improved acetabular cup prosthesis has a cup body with inner convex and outer concave surfaces. The cup body has an apex and a base that defines a plane. The cup body outer convex surface has a curved annular portion between the base and the transition. In one embodiment, the outer convex surface is a curved annular surface extending in between the rim and a distance about two fifths to three fifths (2/5-3/5) of the distance between the rim and the apex. In another embodiment, a plurality of cup bodies are provided in a range of sizes between about 40 mm and 80 mm. Each cup body has a companion rotary reamer that is correspondingly shaped. The companion cup body is oversized between about 1 mm and 3 mm so that a generally constant change in volume is provided for all cup sizes between 40 mm and 80 mm.

An improved acetabular cup prosthesis has a cup body with inner convex and outer concave surfaces. The cup body has an apex and a base that defines a plane. The cup body outer convex surface has a toroidally shaped portion between the base and the transition. In one embodiment, the outer convex surface is toroidally shaped between the rim and a distance about one third of the distance of the rim to the apex. In another embodiment, a plurality of cup bodies are provided in a range of sizes between about 40 mm and 80 mm. Each cup body has a companion rotary reamer that is correspondingly shaped. The companion cup body is oversized between about 1 mm and 3 mm so that a generally constant change in volume is provided for all cup sizes between 40 mm and 80 mm.
