Disclosed is a guided orthopedic bone reamer () for cutting a profile relief shape () into a joint bone (). The reamer () has a cutting head () and an axial guide assembly (). The cutting head () has a profile cutting form () with a rim () and an apex (). The apex () connects to the cutting form () by a set of struts (). An axial guide assembly () has one end () fixed to the apex () and at the other end has a bayonet mechanism () connectable to a drive handle. Rim cutting teeth () are set into the rim () to cut a cylindrical profile (), and bevel cutting teeth () integral to the struts () cut a bevel () onto the cylindrical form () cut into the bone (). A guide pin bore () passes through the apex () and the guide assembly () concentric with the axis of rotation () to receive a guide pin () to guide the reamer () in cutting alignment relative to the joint bone () to be cut.
