An acetabular implant kit includes a first acetabular component that has an inner surface that defines a first concave profile. A second acetabular component includes an inner surface that defines a second concave profile. An instrument includes an elongated body that has a first end and a second end. A head is connected to the second end of the body and has an engagement surface. The engagement surface includes a first convex profile and a second convex profile. The first and second convex profiles are arranged along a longitudinal axis of the head and have a first radius of curvature configured to congruently engage the first concave profile of the first acetabular component. The second convex profile has a second radius of curvature configure to congruently engage the second concave profile of the second acetabular component. The first radius of curvature is different than the second radius of curvature.

An orthopaedic surgical instrument system includes a tibial base trial and a tibial bearing trial. The tibial bearing trial is installed on the tibial base trial from the anterior side of the patient's tibia during an orthopaedic surgical procedure.

A method and system for performing bone fusion and/or securing one or more bones, such as adjacent vertebra, are disclosed. The screws include a threaded tip connected to a main shaft and a threaded outer sleeve that rotates relative to the outer shaft until locked down. Independent rotation of the threaded outer sleeve relative to the threaded distal tip allows compression or distraction to modify the gap between the vertebral bodies. The screws are passed from the inferior to superior vertebra or superior to inferior, for example, through a trans-pedicular route to avoid neurological compromise. At the same time, the path of screw insertion is oriented to reach superior or inferior vertebra. An intervertebral cage of the system is configured for lateral expansion from a nearly straight configuration to form a large footprint in the disc space. The screws and cage may be combined for improved fixation with minimal invasiveness.

The present invention relates to a removable handle (1) for a surgical rasp (2) or similar, the handle (1) and the rasp (2) cooperating, at right angles to their joining ends, via contact faces which at least intersect the mean direction of transmission of the forces between the handle (1) and the rasp (2), said handle (1) having a detachable assembly device (5) and being characterized in that the detachable assembly device (5) has, on the one hand, a means of assembly (6) by engagement in a direction generally perpendicular to said contact faces and using at least two complementary elements, namely a hollow tenon (7) and a mortice (8), and, on the other hand, a locking means (9) for locking said complementary elements (7, 8) in their engaged position, that is to say when the removable handle (1) and the rasp (2) are joined together, with their contact faces applied against each other.

Disclosed is a system for engaging and holding a prosthesis both axially and rotationally relative to an inserter assembly. The inserter assembly can engage an acetabular prosthesis in a selected position, such as axially, with a first portion and then or subsequently engage the acetabular prosthesis with a second portion in a rotationally fixed manner. The acetabular prosthesis can then be inserted into a prepared acetabulum according to a disclosed method with the inserter assembly. The inserter assembly can then be removed from the acetabular prosthesis to allow for reduction of a femur.

A prosthetic knee with an artificial ACL/PCL. The prosthetic knee includes a femoral component and a tibial component. The artificial ACL/PCL connects the femoral component and the tibial component and includes an anterior cruciate ligament portion connecting an anterior anchor point on the tibial component to a posterior anchor point on the femoral component, and a posterior cruciate ligament portion connecting a posterior anchor point on the tibial component to an anterior anchor point on the femoral component. The artificial ligament may be provided as single length of material and may be pre-assembled into an ACL/PCL module having portions that may be inserted into at least one of the femoral component or the tibial component. A system is also provided for total knee replacement that includes a selection of femoral components, tibial components, and one or more ACL/PCL modules of varying sizes,

A modular jaw for attachment to an orthopedic implant extraction tool that includes an elongated body, a claw about a distal end of the elongated body for engaging an object, and a locking mechanism about a posterior end of the elongated body for engaging the orthopedic implant extraction tool. The locking mechanism includes a dovetail lock, a detent mounted to the dovetail lock, and a distally facing surface about a proximal end of the elongated body.

A medical device for implantation in a hip joint of a patient is provided. The medical device is adapted to be fixated to the pelvic bone of the patient. The medical device comprises an inner and an outer surface, wherein a contacting portion, of said inner surface is spherical and adapted to face the center of the hip joint when said medical device is implanted. The medical device is adapted to receive a caput femur or a prosthetic replacement therefor having a spherical portion, wherein said medical device comprises at least one extending portion, extending said contacting portion of said inner surface such that said at least one extending portion clasps said spherical portion of said caput femur, or a prosthetic replacement therefor, such that said spherical portion is restrained in said medical device. Restraining the caput femur in the medical device reduces the risk that the hip joint dislocates when in use by the patient.
