Abstract
A surgical reamer is used in conjunction with a femoral neck cutting guide to enlarge the intramedullary canal of a resected host femur to expose hard cortical bone. The reamer has a longitudinally fluted cutting head that is flexible and able to bend relative to its longitudinal axis whereby to conform to axial or curved cortical bone surfaces to be engaged by like mating surfaces of a hip prosthesis to be implanted therein. In this regard, the cutting head includes a helical band spiralling between the ends of the cutting head.
