Fig. 2From: Cemented vs. uncemented reverse total shoulder arthroplasty for the primary treatment of proximal humerus fractures in the elderly—a retrospective case–control studyThis example shows the typical progression of bone resorption effects on the lateral side of the humeral stem. You can see a good reduction of all bone fragments at 3 months after implantation (left), bone resorption effect grade 2 after one year (middle) and grade 3 after two years (right). A similar process, but less pronounced, can also be seen at the medial sideBack to article page
