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 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.

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 orthopedic prosthesis includes a proximal member which internally accommodates the major motion of a patient, e.g., during walking, thereby reducing wear against a cup or liner. A distal member may be utilized which rotates within the distal member about an axis aligned with the major motion of the patient. The orthopedic prosthesis may also include a head and neck, the neck being rotatably mounted within the head, the head being rotatably mounted within the acetabulum region of a patient.

A method and system for performing bone fusion and/or securing one or more bones, such as adjacent vertebra, are disclosed. The screw includes a threaded distal piece fixedly attached connected to an inner post. Both the inner post and the proximal piece have non-cylindrical receptacles at their proximal ends for engagement with driving tools. Independent rotation of the proximal piece and the distal piece enables for compression or decompression to modify the gap between two bones or bone fragments. During use, the distal piece of the bone screw is placed at least partially within a distal bone, the proximal piece is placed at least partially within a proximal bone, and one of two pieces is rotated while the other is held in a fixed position, causing movement of the proximal and distal bones relative to each other.

A quick release prosthetic connector for detachably joining a threaded prosthetic socket to a prosthetic includes a socket-connect portion configured for connection to the prosthetic socket. A plurality of locking members is carried by the socket-connect portion. The plurality of locking members are positional between a release position and a locking position and normally biased in the locking position. A prosthetic-connect portion is configured for connection to the prosthetic. A plurality of locking member engaging apertures is provided in the prosthetic-connect portion. The plurality of locking member engaging apertures are configured to selectively receive the plurality of locking members, respectively, of the socket-connect portion in the locking position of the plurality of locking members. A lock portion is carried by the socket-connect portion. The lock portion is configured to selectively lock and release the prosthetic-connect portion with respect to the socket-connect portion. A plurality of lock portion depressions is provided in the lock portion. The plurality of lock portion depressions is configured to selectively receive the plurality of locking members, respectively, of the socket-connect portion in the locking position of the plurality of locking members. The plurality of locking members are deployed in the locking position and extend through the plurality of locking member engaging apertures, respectively, in the prosthetic-connect portion and seat in the respective lock portion depressions in the lock portion responsive to rotation of the lock portion in a first direction. The plurality of locking members are deployed in the unlocking position and disengage the plurality of locking member engaging apertures, respectively, in the prosthetic-connect portion and the respective lock portion depressions in the lock portion responsive to rotation of the lock portion in a second direction.
