Abstract: A surgical component, a kit including the surgical component, and a surgical method. The surgical component includes a body portion. The surgical component also includes an elongate stem for inserting into an intramedullary canal of a patient. The elongate stem extends distally from the body portion. The elongate stem has a longitudinal axis; a proximal end; a distal end; and a plurality of splines located on an outer surface of the stem. The splines are circumferentially arranged around the stem. At least some of the splines are tapered such that each tapered spline is narrower at a distal part of that spline than at a part of that spline that is proximal with respect to the distal part. The surgical component further includes an elongate neck portion extending from the body portion at a non-zero angle with respect to the longitudinal axis of the stem.

Abstract: The invention provides a surgical device for performing a controlled resection of the neck of a femur during a hip replacement procedure. The surgical device comprises a body portion having: a frame comprising an aperture dimension for receipt of a femoral head of the femur to position the body portion with respect to a centre of the femoral head; a resection guide for indicating a position of a resection plane on the femoral neck, and an arm extending between the frame and the resection guide. The body portion includes a linear alignment surface for alignment with a femoral shaft axis of the femur while the frame is mounted on the anterior or posterior aspect of the femoral head.

Abstract: An orthopaedic instrument system including an instrument caddy is disclosed. The instrument caddy is configured to receive one or more cutting broaches to house the cutting broaches between orthopaedic surgical procedures. The instrument caddy is also configured to be used during a surgical procedure to assist a user in assembling the cutting broach with another surgical instrument. A method of assembling a surgical instrument is also disclosed.

Abstract: A spiked head assembly for a tibial jig for use during an orthopedic surgical procedure, includes a body and a mount for mounting the spiked head assembly on the tibial jig. The spiked head assembly comprises an elongate member having a central longitudinal axis, a first end and a second end and superior and inferior surfaces. The elongate member also has least one securing spike provided on the inferior surface towards the second end of the elongate member and configured to engage with a bone mass and arms extending from the elongate member in a direction perpendicular to the inferior surface. The arms are spaced apart from a plane that includes the central longitudinal axis and extends substantially perpendicularly to the inferior surface, so that the arms and the inferior surface define an access space for the surgical procedure.

Abstract: A method of marking a surgical instrument with a symbol formed in or on a smooth surface comprises forming a symbol in or on a smooth surface of the surgical instrument; and forming a plurality of angled surfaces over at least part of the area of the symbol. The angled surfaces define a plurality of parallel ridges and grooves in the symbol. The steps of forming the symbol and forming the plurality of angled surfaces take place substantially simultaneously in a single step.

Abstract: A surgical instrument comprising a symbol formed in or on a smooth surface surrounding the symbol, wherein the symbol comprises a plurality of angled surfaces over at least part of the area of the symbol, wherein the angled surfaces define a plurality of parallel ridges and grooves in the symbol. These ridges and grooves create an improved contrast for the symbol relative to the surrounding surface by a combination of different specular reflection of incident light compared to the surrounding surface and shadows formed by the ridges and grooves. A method of marking a surgical instrument with a symbol formed in or on a smooth surface is also described. The method comprises forming a symbol in or on a smooth surface of the surgical instrument; and forming a plurality of angled surfaces over at least part of the area of the symbol, wherein the angled surfaces define a plurality of parallel ridges and grooves in the symbol.
