Risk factors for loosening of cemented glenoid components in anatomical shoulder arthroplasty

Preoperative planning to preserve glenoid subchondral bone in anatomical total shoulder replacement

“…The critical importance of preserving the glenoid subchondral plate has been previously described in the literature. 6 , 20 , 25 This aims to ensure glenoid component stability and minimize the risk of loosening. Frich et al demonstrated that by reaming 1 mm below the subchondral plate, the average strength decreased by 25%, while reaming 2 mm reduced the strength by 70%.…”

“… 25 Furthermore, Raiss et al reported that removing the subchondral plate increased the risk of loosening by 3.7 times. 20 …”
