Fig. 36.1 UNIC shoulder prosthesis system: one single range of humeral stems (cementless, cemented, trauma) fits all articular options (hemi, anatomic, reverse, CTA) With regard to the fundamental principles of reverse…
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…
Fig. 33.1 Grammont reverse concept These concepts, developed from the experience of DELTA CTA, were the foundation for the development of DELTA XTEND. Center of Rotation on the Glenoid Bone: Long-Term…
Fig. 25.1 Surgical classification system of limb-sparing resections of the shoulder girdle Restoration of shoulder function after proximal humeral resection for oncological reasons is still a challenge. In most oncological cases,…
Fig. 20.1 a Anteroposterior radiograph of a left reverse total shoulder arthroplasty with evidence of glenoid component loosening, including fracture of the inferior baseplate screw. The patient was taken for revision…
Fig. 40.2 Small, standard, and large body sizes are available. Up-sizing reverse body height provides a means of adding additional humeral length if needed when tensioning the soft tissues Fig. 40.3 Four…
Fig. 17.1 Radiographs of a postoperative acromial fracture (a) and scapular spine fracture (b) Acromial wear is often seen in patients with cuff tear arthropathy, and this may have a deleterious…
Fig. 22.1 69-year-old male with a painful hemiarthroplasty secondary to subscapularis insufficiency (Top row). This was treated with revision to reverse shoulder arthroplasty with humeral component removal with a successful result…
Fig. 10.1 The anatomical prosthesis (left) maintains the anatomical center of rotation of the humerus and the moment arm (M1) of the middle deltoid force (F). The reverse prosthesis (right) displaces…
