1. 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 (i) the adjustable handle is arrangeable relative to the body in a first and a second position, (ii) in the first position (a) the leading end is arranged relative to the handle coupling such that the handle axis is offset relative to the longitudinal axis, (b) the second connector is engageable by the driving instrument, and (c) the adjustable handle can be gripped by a user to provide additional support, and (iii) 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.
