Fig. 9.1 Schematic of the shoulder simulator. The scapula was potted and rigidly mounted to the simulator such that the glenohumeral joint approximated anatomic orientation. Actuators applied displacement to the deltoid…

Indications – Physiologic age > 70 – 4 part fractures – 3 part fractures with severe greater tuberosity comminution – Articular head-split fractures Contraindications – Dementia patients or patients with non-functional deltoid…
