In the article entitled ¿revision of reversed total shoulder arthroplasty.Indications and outcome.¿ written by mazda farshad; marion grogli; sabrina catanzaro; and christian gerber; was reviewed.The articles purpose was a retrospective study to identify the reasons for revision of reverse total shoulder arthroplasty (rtsa) and to report outcomes.The article was based on rtsa¿s performed with implants of the: delta iii (depuy) 232 implanted, and a competitor, 248 implanted between 1999-2008.67 cases needed at least one additional intervention to treat a complication, 30 of them needed a second, eleven of them a third and four a fourth additional intervention.The most common complication requiring a first intervention was instability, followed by a hematoma or superficial wound complications and complications of the glenoid component.Patients benefited from the rtsa despite the need of additional interventions as indicated by a mean increase in total constant-murley score from 23 points before rtsa to 46 points at final follow-up.Complications were as follows--all of which required revisions: instability resulting in subluxations or dislocation.Five were closed reductions, seven required a change of components to a selection of a higher humeral polyethylene inlay was used in three, revision of glenoid component in two, and revision of a humeral component in two cases.Eight resulted in hematomas with simple evacuation.Three complications of glenoid component-one changed glenoid conversion and two component wear.One for pain.Two deficient in external rotation.Three for infection.Three for humeral component loosening.Two disturbing orif material.Two periprosthetic fractures.One dislocation of greater tuberosity.One heterotopic ossification.
