An orthopaedic reamer driver includes a tubular housing having at least one first positioning feature. A driveshaft within the housing has a drive end. A variable angle cap is pivotally coupled with the housing adjacent the drive end. The variable angle cap includes at least one leg extending along a side of the housing. Each leg has a second positioning feature selectively engaging and disengaging with a corresponding first positioning feature at a selected one of a plurality of angular positions. Each second positioning feature maintains the variable angle cap at the selected angular position when engaged with the corresponding first positioning feature. A variable angle joint is coupled to the drive end, and a reamer drive head is coupled to the variable angle joint.
