A prosthetic acetabular cup impaction plate comprising an annular cup engaging surface comprising an annular array of first shape portions adapted to substantially complement portions of the natural shape of the right side acetabulum, which first shape portions are intersected by an annular array of second shape portions adapted to substantially complement the natural shape of the left side acetabulum.

Prosthetic acetabular cup impaction plate

A prosthetic acetabular cup inserter and impactor has an expandable annular cup engaging element to engage the inner surface of a cup to be inserted in the acetabulum. An expander is provided for expanding the cup engaging element which is connected to one end of a handle via a hollow or partly hollow extension portion. The other end of the handle is provided with an anvil. An elongate operator is located within the extension portion and connected to the cup engaging element. A device is provided for moving the elongate operator to pull the cup engaging element towards the expander.

Prosthetic acetabular cup inserter and impactor

A prosthetic acetabular cup inserter and impactor has a body, a cup engaging element disposed at a first end of the body which is adapted to engage an inner surface of a cup with which it is used. An operating system is adapted to axially rotate the cup engaging element in relation to the body in use. An impaction plate that is adapted to engage an undulating rim of the cup is disposed between the body and the cup engaging element. The impaction plate is connected to the operating system by a linkage which acts to axially rotate the impaction plate in unison with the cup engaging element in use.

Acetabular cup inserter and impactor

A prosthetic acetabular cup inserter and impactor has a body, and a cup engaging element disposed at a first end of the body and adapted to engage an inner surface of a cup with which it is used via outward biasing of the cup engaging element. The cup engaging element increases in cross-sectional area from an inner end thereof to a fullest transverse section, and decreases in cross-sectional area from said fullest transverse section to an outer end thereof. The cup engaging element has a tapered central bore engaged by a conically tapered actuation element moveable in the bore. The cup engaging element has a slot therethrough allowing the element to resiliently expand on movement of the actuator in the bore.
