Abstract: A surgical instrument assembly includes a metallic hemispherical component and a driver component removably coupled to the hemispherical component. The metallic hemispherical component has a convex outer surface configured to engage a patient's natural acetabulum, a concave inner surface positioned opposite the outer surface and defining a cavity in the hemispherical component, a plurality of cutting teeth extending outwardly from the outer surface, and a plurality of apertures defined in the inner surface. The driver component has a shank and a plurality of ribs secured to, and extending outwardly from, the shank. Each rib has a tab that is received in a corresponding aperture of the hemispherical component to secure the driver component to the hemispherical component.

Abstract: An orthopaedic surgical instrument system for use in preparing a patient's bone is disclosed. The surgical instrument includes a cutting guide block configured to be secured to a surgically-prepared surface of the patient's bone, and a cutting tool to be used in conjunction with the cutting guide block to resect a section of the patient's bone. A method of performing an orthopaedic surgery is also disclosed.

Abstract: A modular femoral prosthesis for use during performance of a hip revision procedure includes a proximal body component, a distal stem component, and a locking bolt. Surgical instruments and methods for use in implanting such a modular femoral prosthesis are disclosed.

Abstract: Surgical cutting instruments and methods of use are described. The surgical cutting instrument (100) comprises an instrument body (102) with a first attachment mechanism (106) at a distal end. A cutter (104) has a central core (110), a plurality of cutting formations (130, 136) and a plurality of lobes (112, 114, 116) extending from the central core. The central core has side walls (118, 120, 122) which define an entirely open mouth and the side walls include a second attachment mechanism (140, 142, 144) which can interact with the first attachment mechanism to releasably attach the cutter to the distal end of the instrument body. At least one cutting formation (136) is provided on an end outer face (138) of the cutter opposite the entirely open mouth.

Abstract: Surgical instruments and methods for use in implanting a modular femoral prosthesis during performance of a hip revision procedure are disclosed, and include a distal reamer operable to ream an intramedullary canal of a patient's femur during a surgical procedure. The distal reamer includes an elongated shank having a cutting head formed in a distal end of the elongated shank and a drive connector formed in a sidewall positioned at an opposite, proximal end of the elongated shank. The cutting head has a plurality of helical cutting flutes arranged in a geometry that corresponds with the geometry of the distal stem component. The drive connector has a female drive socket and a number of locking slots formed in the sidewall so as to open into the female drive socket.

Abstract: A controlled force surgical implant impaction instrument is provided which includes a striking assembly, a retaining pin, and an actuator component. The striking assembly is configured to impact a surgical implant. The retaining pin is moveable between a first position and a second position. In the first position, the retaining pin inhibits distal movement of the striking assembly. In the second position, the retaining pin does not inhibit distal movement of the striking assembly. The actuator component includes a reloading channel. The actuator component is movable between a third position and a fourth position. In the third position, the retaining pin is in the first position and the retaining pin cannot be forced along the reloading channel. In the fourth position, the striking assembly can be used to move the retaining pin along the reloading channel.
