Abstract: A surgical component, a kit including the surgical component, and a surgical method. The surgical component includes a body portion (50). The surgical component also includes an elongate stem (2) 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 (4); a proximal end (8); a distal end (6); and a plurality of splines (20, 30) 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.

Abstract: An instrument comprising a body comprising a distal end spaced apart from a proximal end relative to a longitudinal axis and a handle coupling located near the proximal end, the body defining a channel running between the distal end to the proximal end; a drive comprising a first connector located adjacent the distal end and adapted to be connected to a driven instrument, a second connector located adjacent the proximal end and adapted to be connected to a driving instrument, and a drive shaft arranged in the channel, the drive shaft coupling the second connector to the first connector; and an adjustable handle located near the distal end, the adjustable handle comprising a grip spacing apart a leading end from a trailing end along a handle axis, the leading end coupling the handle to the handle coupling, the trailing end shaped to define an impaction plate; wherein the adjustable handle is arrangeable relative to the body in a first and a second position, in the first position the leading end is arranged relative to the handle coupling such that the handle axis is offset relative to the longitudinal axis, and in the second position the leading end is arranged relative to the handle coupling such that the handle axis is parallel to the longitudinal axis.

Abstract: A planer comprising: a housing (10) encasing a drive (150) and a plane (100); the drive defining a drive axis, a drive first end (152) and a drive second end (154), the drive first end arranged to receive a torque and the drive second end coupled to the plane; wherein the housing holds the plane in such a way that a torque applied to the drive causes the plane to oscillate linearly along a translation axis that is offset relative to the drive axis.
