Background : reverse shoulder prosthesis is a prosthesis which has been used clinically in Europe since 1985 and is approved for use in the United States in 2004. This unique prosthesis has a base attached to the glenoid , which holds the spherical component , while the humeral component that includes polyethylene contained in it is flat . This design configuration is " upside down" seen with conventional arthroplasty , in which the ball-shaped components that are part of the humeral component. Indications for prosthesis upside down are: (1) arthritis painful associated with a tear of the rotator-cuff which can not be repaired (torn rotator-cuff arthropathy), (2) hemiarthroplasty fail with tears rotator-cuff which can not be repaired, (3) pseudoparalysis Massive, rotator-cuff tears that can not be repaired, (4) some reconstruction after tumor resection, and (5) some shoulder fractures can not be repaired or reconstructable with other techniques. This prosthesis can produce a significant reduction in pain and some improvements in the functioning of most of the indications mentioned. However, the unique configuration and insertion challenge could result in higher incidence of complications are not uncommon. Some complications, such as dislocation of components, similar to a conventional shoulder replacement. Other complications, such as the formation of stress fracture of the scapula and acromial unique to this prosthesis. Conclusion: The configuration of the reverse prosthesis, and normal radiographic appearance of potential complications related to the use.
