Reverse total shoulder’s humeral components are subject to greater forces than the humeral portion of an anatomically total shoulder. Secure humeral fixation therefore is necessary. Impaction grafting with standard length reverse humeral stems is a great way to fixate the bone while also preserving the humeral stock. Standard length stems are applicable to all shoulders, even those with osteopenia. As you can see, the standard stem is impaction-grafted to preserve the humeral bones stock.
Stemless reverse shoulders arthroplasty by the authors: Radiological and clinical outcomes at least two years after surgery indicate that a stemless design for reverse shoulder arthroplasty was created to “preserve bone”.
They presented the short-term (2-year) radiological and clinical results of the implant. However, the hypothesis that this design would produce better radiological and clinical results than stemmed implants or be a more economical alternative to reverse total shoulder surgery with a standard stem was not tested.
26 patients experienced capsular notching (24.3%). There was also humeral loosening (5 patients, 4.3%) and glenoid loosening (4 patients, 3.5%). Eight patients underwent an…
