Abstract: The present invention relates to a positioning device (100) for implantation of prosthesis in a long bone, in particular for implantation of humeral prosthesis, comprising: at least one centering element (101) with a channel (102) configured to house an intramedullary nail (11); a support element (103) configured to hold a reference mask (200) on a plane (12) at a resected metaphysis of the long bone; an adjustment element (104) configured to connect the centering element (101) and the support element (103), wherein the adjustment element (104) further comprises a displacement device (105) configured to provide a controlled offset to the support element (103) for displacing the reference mask (200) over the plane (12) of the resected metaphysis.

Abstract: A modular reverse shoulder prosthesis, comprising: a stem (110) comprising a tapered body (111) and a first annular housing (112); a tray (120) comprising a dome element (121) for insertion into the first annular housing (112), and further comprising a second annular housing (122); a liner (130) comprising an engaging element (131) for at least partial insertion into the dome element (121), and further comprising a joint concave element (132) configured for coupling with the second annular housing (122). The second annular housing (122) of the tray (120) comprises a raised edge (123) configured to support the joint concave element (132) and which defines an overall outline having a different development in height at least in diametrically opposite portions (123a; 123b) of the tray (120).
