Results of Shoulder Arthroplasty in Primary Gleno-humeral Osteoarthritis

Metal-backed glenoid implant with polyethylene insert is not a viable long-term therapeutic option

“…However, long-term fixation of the glenoid component remains an unsolved problem, and loosening of cemented polyethylene (PE) glenoid components represents an important cause of failure in TSA. 17,22,24 The rate of glenoid lucent lines after cemented all-PE implants in anatomic TSA has been reported to be up to 90%. To improve glenoid fixation and to reduce glenoid lucent lines, uncemented fixation with porous coated or tissue-ingrowth components has been developed with the aim of achieving more stable fixation to the bone and a corresponding increase in implant survival.…”

“…To improve glenoid fixation and to reduce glenoid lucent lines, uncemented fixation with porous coated or tissue-ingrowth components has been developed with the aim of achieving more stable fixation to the bone and a corresponding increase in implant survival. 1,[7][8][9]15,17,23 Despite the body of proof indicating that uncemented glenoid implants are at risk for failure and revision, uncemented metal-backed (MB) glenoid components are still commonly used in TSA. 1,[5][6][7][8][9][13][14][15]19,20,23,[25][26][27] Moreover, with the recent success of reverse prostheses, there is currently renewed interest in the development of ''universal'' uncemented glenoid MB implants.…”

Schulterendoprothetik bei primärer Omarthrose

“…Kempf et al [4] fanden im Rahmen der AequalisGruppe nach 1,5 Jahren einen Constant Score von 69,8 Punkten bei 141 Totalprothesen. In den Untereinheiten des CS berichtet diese Studie über 13 Punkte für den Schmerz, 16,9 Punkte für die Aktivität, 32 Punkte für die Mobilität und 8 Punkte für die Kraft.…”
