The use of inverted prostheses to replace shoulder joints damaged by degenerative or traumatic processes has become widespread over the past three decades. Current designs, used correctly, can restore function and improve pain in the majority of patients in whom they are implanted.

The aim is to carry out a more detailed follow-up of the subjects who are implanted with this prosthetic model on a primary basis, analysing the clinical and radiological results and evaluating the presence of adverse effects of the prosthesis or short-term complications. For this purpose, subjects will be closely monitored for two years.

The use of inverted prostheses to replace shoulder joints damaged by degenerative or traumatic processes has become widespread over the past three decades. Current designs, used correctly, can restore function and improve pain in the majority of patients in whom they are implanted.

However, there are complications associated with shoulder arthroplasty surgery, such as wear of the prosthetic components, infection, allergy to the prosthetic components, or failure to restore full shoulder function. The occurrence of these complications is affected by multiple factors dependent on the subject, the surgeon and/or the implant used.

Inclusion Criteria:

• Patients who, after receiving information about the study design, the aims of the study, the possible risks that may arise from it and the fact that they may refuse to participate at any time, give their written consent to participate in the study.
• Be over 18 years of age.
• Have a shoulder joint disorder that is amenable to treatment with an Embrace reverse arthroplasty.
• Have a CT or MRI scan performed no more than 6 months prior to surgery.
