[Glenoid reconstruction in revision shoulder arthroplasty]. Oper Orthop Traumatol. 2019 Mar 15;: Authors: Gohlke F, Werner B, Wiese I Abstract OBJECTIVE: The aim of the surgical technique is the stable fixation of a glenoid baseplate and reconstruction of bone loss with correction of version, inclination, and medialization of the joint line. INDICATIONS: Significant glenoid bone loss due to glenoid loosening or wear in revision shoulder arthroplasty. CONTRAINDICATIONS: Active infection, inoperability due to poor health condition. SURGICAL TECHNIQUE: Reconstruction of advanced glenoid bone stock in case of glenoid loosening of total shoulder arthroplasty can be performed either with autografts and allografts or metallic augmentation together with reverse baseplates in a one- or two-stage procedure. The preferred fixation mode was a transfixation technique using autograft and baseplates with extra-long coated or threaded post with 2-4 locking screws. Baseplates with an extended post and locking screws adjustable in various inclination are required to achieve fixation along the "3-column concept" which is used by the authors based on a recently introduced classification algorithm, which is based on the remaining bone stock available for fixation of the post in native bone stock. POSTOPERATIVE MANAGEMENT: The standard protocol with an abduction brace for 6 weeks and passive exercises is modified, depe...
