A novel method and instrumentation for insertion of humeral (HC) and glenoid (GC) total shoulder implant using arthroscopic visualization for bony preparation as well as insertion of components through small incisions. Mini instruments (24) and cannulated guides and reamers (64) are used in order to perform the procedure under direct arthroscopic visualization. For ease of insertion, the components are inserted separately and assembled in situ. Securing the humeral components in place is accomplished with bicortical screw (75) transfixing the central peg (2a) of component. Also disclosed are components, parts thereof and instruments used therewith.
