[Resection arthroplasty and arthrodesis in revision shoulder arthroplasty].

Shoulder arthrodesis and resection arthroplasty can be used as salvage procedures to treat severe complications after shoulder prosthesis failure. for both procedures, the indication and patient selection must be very strict. Shoulder arthrodesis after prosthesis failure can be indicated in young patients in case of chronic neuromuscular dysfunction. Filling the bony defect with either autologous or allogenic material and osteosynthetic primary stability are decisive for a good functional outcome. Aftercare comprises immobilization for 12 weeks and physical load is increased thereafter, depending on the sufficiency of bony consolidation. Resection arthroplasty after shoulder prosthesis failure is mostly reserved for multimorbid patients in case of a chronic infection. Thorough debridement and adequate systemic antibiotic treatment are crucial to achieve bacterial eradication.
