Reverse shoulder arthroplasty glenoid fixation: is there a benefit in using four instead of two screws?
This study demonstrates no statistical difference in baseplate motion between 2-screw and 4-screw constructs. Therefore, using fewer screws could potentially lead to a reduction in operative time, cost, and risk, with no significant negative effect on overall implant baseplate motion.
Smoking and ERT-use are associated with lower total and central fat in monozygotic postmenopausal twins. In current smokers, the lower central adiposity appears related to its influence on total body fat. In ERT-users, lower central fat may contribute to the reduced cardiovascular risk associated with postmenopausal oestrogen use.
