A total shoulder replacement arthroplasty system which encompasses replacement of the humeral head with a modular artificial humeral head. The artificial humeral head is attached to an implant, which is designed to fit in the metaphysis without protruding into the diaphysis, thus obviating the need to ream the diaphysis. In addition, the implant is designed to allow bone in-growth into the implant, thus avoiding the use of cement to affix the implant. A device for resecting the humeral head to facilitate easy implantation of the prosthetic is also disclosed, as is an operative technique used to implant the prosthetic.
