Surgical component, kit and method

A surgical kit including a surgical component, the surgical component comprising:

• a body portion;
• an elongate stem for inserting into an intramedullary canal of a patient, wherein the elongate stem extends distally from the body portion and has:
• a longitudinal axis;
• a proximal end;
• a distal end;
• and
• a plurality of splines located on an outer surface of the stem, wherein the splines are circumferentially arranged around the stem, and wherein 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, wherein at least some of the tapered splines each have a distal region and a proximal region, wherein those splines are tapered in their distal region and have a constant width in their proximal region or those splines are tapered in their proximal region and have a constant width in their distal region, and wherein, in each spline having a tapered part and a part having a constant width, an interface between the distal region and the proximal region of that spline is located proximally with respect to a fixation region of the stem;
• and
• an elongate neck portion extending from the body portion at a non-zero angle with respect to the longitudinal axis of the stem.

A surgical method comprising using a surgical component, the surgical component comprising:

• a body portion;
• an elongate stem for inserting into an intramedullary canal of a patient, wherein the elongate stem extends distally from the body portion and has:

• and
• an elongate neck portion extending from the body portion at a non-zero angle with respect to the longitudinal axis of the stem,
• the method comprising:
• inserting the elongate stem into an intramedullary canal of a patient.
