2025年3月11日 · Reverse Shoulder Arthroplasty is a type of shoulder arthroplasty that uses a convex glenoid hemispheric ball and a concave humerus articulating cup to reconstruct the glenohumeral joint. The center of rotation is moved inferiorly and medialized which allows the deltoid muscle to act on a longer fulcrum and have more mechanical advantage.

In order to address a wide range of possible patient anatomies, the Comprehensive Reverse System provides one of the most complete glenoid portfolios on the market and includes Mini and Standard Baseplates, Augmented Baseplates, Vault Reconstruction System and compatibility with Trabecular Metal™ Reverse System to solve any glenoid deficien...

2024年3月13日 · The suitable glenosphere should allow enough separation from the scapular pillar anteriorly, posteriorly, and inferiorly and free humeral component movement without superior impingement. The 36 mm glenosphere size is commonly used …

Background: The role of glenosphere size in reverse shoulder arthroplasty (RSA) may be important in prosthetic stability, joint kinematics, rotator cuff tension and excursion, scapular impingement, humeral lateralization, deltoid wrap, and the occurrence of "notching."

We conducted a 10-year retrospective review of 145 SMR reverse shoulder arthroplasties (LimaCorporate, Udine, Italy) in 132 patients with radiographs at a minimum of 2 years postoperatively. The primary outcome measure was the survivorship of …

It is commonly known that glenosphere size usually comes down to surgeon preference as a smaller glenosphere lends itself to easier insertion but a larger glenosphere may reduce the risk of future dislocation.

2017年7月24日 · The role of glenosphere size in reverse shoulder arthroplasty (RSA) may be important in prosthetic stability, joint kinematics, rotator cuff tension and excursion, scapular impingement, humeral lateralization, deltoid wrap, and the occurrence of “notching.”

Lateralization and glenosphere size increased significantly deltoid muscle loading, especially in the clavicular head. According to these in-vitro data, the high variability in the amount of lateralization influences the soft-tissue balance in reverse shoulder arthroplasty.

2021年2月11日 · Therefore, the primary objective of this study was to investigate the relationship between preoperative glenoid inclination, postoperative glenosphere inclination and inclination change (∆INC) from pre- to postoperative on clinical outcomes after RSA.

2024年5月29日 · Glenosphere diameter and lateralization are key components of reverse total shoulder arthroplasty (RSA) design and biomechanics.
